Diet tips and strategies for prediabetes

Published

on

An individual with prediabetes has high blood sugar levels, but not yet within the diabetes range. There is always time to monitor the levels and to stop the onset of diabetes.

According to research published in the Lancet in 2012, 5–10% of people with prediabetes develop diabetes every year worldwide, and up to 70 % of people with prediabetes continue to develop diabetes.

This risk can be decreased by between 40 and 75 percent by taking preventive measures, such as dietary changes. Indeed, the study says that between 5 and 10 percent of individuals with prediabetes go back to normal levels each year.

There is a strong possibility that if a person with prediabetes knows what action to take, they will avoid the development of diabetes.

Two main lifestyle factors are commonly included in preventive plans: a balanced diet and daily exercise.

Prediabetes diet: Foods to eat and avoid

Kinds of diets
Dietary changes can reduce the risk of prediabetes progressing to diabetes.

Results of the Diabetes Prevention Program in the United States have proposed that every 2.2 pounds (1 kilogram) they lose in a year in people who are overweight will reduce their risk of developing diabetes by 16%.

This will be equivalent to a 58-percent risk reduction after 3 years.

A diet that can aid in weight loss and prediabetes treatment will usually contain foods that include:

The person should eat plenty of:

  • vegetables
  • whole grains
  • lean meats
  • protein-packed legumes

In order to prevent added sugar, they should be careful. Fruits contain sugar, but they also provide fiber and other nutrients. For this reason, in their diet, a person may include a limited amount of fruit.

Glycemic index

The glycemic index ( GI) is a useful tool to calculate carbohydrate types and to select those that are safe. It is dependent on how easily food sugar is going to reach the bloodstream.

People with diabetes need to take care of the amount of carbohydrates they ingest, and particularly added sugar.

Any meal containing carbohydrates or sugar, however, is not necessarily bad. Natural sugars are found in vegetables, and whole grains are high in carbohydrates, but they also provide fiber and other nutrients. This make them acceptable, with moderation, for a person on a diet for prediabetes.

An index, or list, of foods is the GI. It rates foods by the rate at which they influence the amount of blood sugar. The highest score is 100, while the lowest score is 0.

It does not measure amounts of anything, but compares the forms in which food causes sugar levels to increase in the blood, with the highest level being 100.

Some foods that contribute to an unusually high spike in blood sugar can have a value above 100. Russet potatoes have a score of 111 on the GI, according to Oregon State University.

Sample GI values

Here are some more sample values:

  • fruit roll-ups: 99
  • plain white baguette: 95
  • whole-grain bread: 51, depending on the type
  • cornflakes: 93
  • muesli: 66
  • natural oatmeal: 55 on average
  • white rice: 89
  • brown rice: 50
  • full-fat milk: 41
  • skim milk: 32
  • watermelon: 72
  • banana: 62
  • apple: 39
  • unsweetened apple juice: 42
  • white spaghetti: 58
  • wholemeal spaghetti: 42
  • baked beans: 40, but check the brand

Depending on the individual item, the carb amounts can also differ. For instance, some apples are sweeter than others, and different ingredients are used by manufacturers.

The values are shown by a study published in Diabetes Treatment, with variations. These values were set by researchers in 2008, and checked from time to time.

What makes a low or high GI score?

Slowly, the body digests whole grains and high-fibre foods. Their sugars gradually reach the bloodstream. Foods which contain fiber will have a lower GI than those made with refined ingredients, such as fruit and whole grains.

Sugars and refined carbs are easily absorbed by the body. This triggers a sudden increase in blood sugar levels and a “sugar spike,” or elevated blood glucose levels. A high GI score would be obtained for foods containing refined carbs and added sugars.

This is why the GI value of white bread is greater than that of wholemeal bread.

An individual with prediabetes needs a sugar spike to be prevented.

  • foods with a GI value of 55 or less raise blood sugar levels those with GI values between 56 and 69 raise blood sugar levels at a moderate rate
  • those with a GI value of 70 or above raise blood sugar levels rapidly

Some GI tips

Whole-grain-bread-nccmed

It is not easy to tell a food’s GI value simply by looking at it.

Here are some tips that may help:

  • Foods that contain refined sugars usually have a higher GI value than foods that contain natural sugars, such as fruit.
  • Whole foods tend to have lower GI values than products made with refined grains, such as white bread or rice.
  • Sweet potatoes, most vegetables, whole fruit, and legumes have lower GI values than white starchy vegetables, such as potatoes.
  • As most fruits and vegetables ripen, their sugar content increase and their GI value goes up.
  • Pastas tend to be low-GI foods because of the way their starches are bound.
  • Parboiled rice, basmati, and brown rice all have lower GI values than short-grain or jasmine rice.
  • Homemade oatmeal or stone-cut oats have a lower GI count than packaged oatmeal.

However, it is best to ask a doctor or dietitian for advice that suits your situation.

Counting carbs

Some people think that carbohydrate counting helps to ensure an adequate quantity of carbohydrates.

It is not inherently safe to cut carbs entirely. Some high-carb foods provide other nutritional benefits, such as potatoes and peas.

The same nutrients can, however, be given by many low-carb foods. An simple way to minimize carb consumption may be to substitute high- for low-carb options.

For example:

The following starchy vegetables are high in carbs:

  • potatoes
  • peas
  • corn

It is necessary to monitor portions to prevent a spike in blood sugar while consuming these carbohydrates. Around 30 grams of carbohydrates are found in one cup of potatoes, peas or corn.

Fewer carbs per portion have the following and are high in fiber and other nutrients:

  • asparagus
  • broccoli
  • carrots
  • celery
  • green beans
  • lettuce other salad greens
  • peppers
  • spinach
  • tomatoes
  • zucchini

45 to 65 percent of a person’s diet can consist of carbohydrates, the National Institute of Health suggests.

Eat regular meals

An individual with prediabetes needs to maintain as steady a level of blood sugar as possible.

Fasting may cause drastic changes in blood sugar levels, but it can help to control glucose levels by consuming small meals at regular intervals.

Experts recommend:

  • eating three properly-portioned meals regularly throughout the day, no more than 6 hours apart
  • ensuring meals that are balanced, with each containing a source of protein, fat, and carbohydrates

To check whether a meal is correctly portioned, a person might use the plate method.

The plate method

The Diabetes Society recommend that each meal should consist of:

  • one-half vegetables, at least two servings
  • one-quarter meat, fish, or an equivalent
  • one-quarter carbs, for example, rice, pasta, bread or potatoes
  • a drink of water, low-fat milk, or other healthful options
  • a piece of fruit

In addition, each meal should include at least three out of the four key food groups.

The four groups are:

  • fruit and vegetables
  • grain products, preferably whole grains
  • milk or an alternative
  • meat, fish, lentils, or an alternative

Studiesa have found that for people who need or want to lose weight, using a smaller plate can encourage people to eat less.

The DASH diet

For better health , health authorities, including the National Institutes of Health, recommend adopting the DASH diet. It can assist people with prediabetes in conjunction with carb counting and knowledge of the GI.

The emphasis of this diet is not on eating less calories, but on making healthier decisions.

People are encouraged to eat:

  • vegetables
  • fruits
  • whole grains
  • fat-free or low-fat dairy products
  • fish
  • poultry
  • beans
  • nuts
  • vegetable oils

People should avoid foods that are high in saturated fats and sugar, such as:

  • fatty meat
  • full-fat dairy products
  • coconut, palm, and other tropical oils
  • sweets
  • sugary drinks

Eating out

It does not mean that a person should not eat out or enjoy their food with prediabetes, but they need to be aware of decisions.

Here are some tips for eating out:

  • Encourage friends and family to eat with you at restaurants that have healthful options.
  • Choose a salad and ask to have it without dressing, or ask for a little olive oil or lemon juice to dress it with.
  • Avoid buffets if it is too tempting to have more than one plate.
  • Go for quality—such as fresh ingredients—rather than quantity.
  • See if the menu lists the calories for a dish.
  • Opt for sparkling water with ice and a slice of lemon, instead of soda or alcohol.

Meal planning

You might be wondering what you should eat if you have just been diagnosed with prediabetes.

Here are several suggestions during the day for meals.

MealWhat to eatWhat to avoid
BreakfastRolled or whole oatsWholemeal breadWhole peanut butter without added sugarFruitUp to 4 ounces of 100% fruit juice with no added sugarCoffee or tea with low-fat milk and no sugarWhite bread and bagelsSweetened breakfast cerealSweetened juicesMany “specialty” coffees from coffee shops contain sugar, so check before buying
LunchBaked beans on wholemeal toastBrown rice, lentils, and salad with a little olive oilHome-made vegetable soupsAn apple or pear, or a cup of melon or berriesBagels, baguettes, and other white or refined breadsBurgers and many fast-food itemsSalad dressings and ketchup with added sugar
DinnerYam or sweet potato with chicken, broccoli and asparagusWholemeal pasta with home-made tomato sauce and saladFruits, ice-cream made with fruit and yogurt without added sugarPizzasReady-made saucesFatty meats
SnackNuts, fruit, low-fat, natural yogurtCandies and ready-made “health” bars, unless the details on the label show they are really low in added sugar

Fruit is highly nutritious in moderation, and contains fiber, water, vitamins , and minerals.

Enjoy fruit with protein or healthy fats such as nut butter, a small handful of nut seeds, or avocado to reduce the effect on blood sugar and keep you full for longer.

Check with your doctor or dietitian to see how many of your favorite things are suitable.

To prevent sugar spikes, you should aim to even out your carb intake during the day. Eating a lot of sweet foods for breakfast and then skipping them for the rest of the day would not help.

Alcohol

Consumption of alcohol can increase weight and the risk of diabetes as well.

One study showed that “risky” alcohol use in men increased their chances of developing diabetes significantly.

Limiting or avoiding the intake of alcohol can also enable a person to regulate their level of blood glucose and lead to weight loss.

Stop sugar mixers, such as soda, when drinking alcohol.

Other strategies

Diet alone does not prevent the development of prediabetes into diabetes. Other strategies include exercise and medication.

Exercise

Physical exercise can help an individual lose weight and regulate the amount of sugar in their blood. Exercise utilizes excess blood sugar for energy and can increase the sensitivity of insulin.

An article published in Exercise and Sports Science Australia recommends 210 minutes of moderate-intensity exercise or 125 minutes of intense exercise per week for individuals with prediabetes.

30 minutes of physical exercise, such as brisk walking, is recommended by the American Diabetes Association at least five days a week, preferably every day. One advantage of exercise is that it can help reduce levels of blood glucose.

Activities that could assist include:

  • swimming
  • brisk walking
  • running
  • strength training
  • flexibility

Housework, gardening, and other activities can all contribute. The American Diabetes Association recommends that every 30 minutes, individuals working in a sedentary job can get up and walk around.

Medications

A physician may prescribe metformin to help regulate blood sugar levels for some people with prediabetes.

This can help, but it does not seem to be as successful as lifestyle interventions, and metformin may have side effects, like all medications.

For this reason, physicians advise most individuals to use lifestyle interventions to the greatest extent possible.

A research published in the Annals of Internal Medicine found that less than 4 percent of people with prediabetes were given the medication metformin by American doctors.

At least one study published in 2014 reported that dietary improvements and exercise are successful in preventing diabetes progression.

RECALL OF METFORMIN EXTENDED RELEASE

In May 2020, the Food and Drug Administration (FDA) recommended that some makers of metformin extended release remove some of their tablets from the U.S. market. This is because an unacceptable level of a probable carcinogen (cancer-causing agent) was found in some extended-release metformin tablets. If you currently take this drug, call your healthcare provider. They will advise whether you should continue to take your medication or if you need a new prescription.

What is prediabetes?

Diabetes and prediabetes are metabolic disorders. The condition may be caused by actions and health conditions that impair the ability of the body to metabolize, consume, or store energy.

Why do blood sugar levels rise?

Factors that can cause blood sugar levels to rise include:

  • insufficient insulin production
  • impaired insulin expression
  • the cells not responding properly to insulin

Prediabetes can affect anyone, but some people are more likely to experience it.

Factors that increase the risk include:

  • being over the age of 40 years
  • having low activity levels
  • carrying excess weight

Other factors include:

  • family or genetic traits, including having a direct relative with diabetes or being from certain ethnic or racial groups, including Pacific Islanders and African Americans
  • having high blood pressure, heart disease, or both
  • having high levels of triglyceride and “bad” cholesterol, or high-density lipoprotein (LDL)
  • having low levels of “good” cholesterol, known as high-density lipoprotein (HDL)
  • having excess belly fat or carrying extra weight around the middle, rather than the hips
  • having another specific condition, such as polycystic ovary syndrome (PCOS), gestational diabetes, and low testosterone in men

Warning signs

The symptoms of prediabetes, if there are any, may be hard to spot.

A person may notice:

  • increased thirst and urination
  • tiredness
  • difficulty concentrating
  • unexpected weight changes

On different parts of the body, such as the neck, elbows, knuckles, and knees, skin darkening, called acanthosis nigricans, may also occur. It may take more time than usual for daily wounds to heal.

A glucose monitor can be used by people to check their blood sugar levels.

Takeaway

Prediabetes can develop into diabetes if a person does not take care of their diet and exercise regime.

However, a person with this diagnosis has a decent chance of avoiding a more severe condition in the future by taking the right action.

There is no one-size-fits-all diet for prediabetes. Anyone who gets a diagnosis should ask for advice from their doctor or healthcare provider.

Uses of vitamin B-12 level test: Normal ranges, and results

Published

on

The amount of vitamin B-12 in the blood or urine is measured in a vitamin B-12 level test to determine the body’s overall vitamin B-12 reserves.

Vitamin B-12 is required for a variety of body functions, including neuron function, DNA and red blood cell formation.

Treatment is required if a person’s vitamin B-12 levels fall outside of the usual range. Vitamin B12 deficiency can cause neurological symptoms as well as fatigue, constipation, and weight loss. B-12 levels that are too high could indicate liver disease, diabetes, or another condition.

Continue reading to learn more about B-12 testing and what the results indicate.

Purpose of a vitamin B-12 level test

worried lady

The vitamin B-12 level test determines the amount of vitamin B-12 in your body. Doctors can use the data to see if low vitamin B-12 levels are causing symptoms.

If a person exhibits any of the following symptoms, a doctor may recommend a vitamin B-12 level test:

Vitamin B-12 insufficiency

Vitamin B-12 deficiency is thought to affect up to 15% of people in the United States, according to research. The following are signs and symptoms of a deficiency:

  • fast heartbeat
  • numbness and tingling in the hands and feet
  • poor memory
  • a sore mouth or tongue
  • confusion
  • dementia
  • depression
  • difficulty maintaining balance

Vitamin B-12 deficiency in infants can cause them to underachieve. They may have mobility issues in addition to developmental delays.

Pernicious anaemia

A vitamin B-12 level test may be required for people who have signs of low iron. Pernicious anaemia is caused by a lack of vitamin B-12 absorption, resulting in poor red blood cell causes.

It usually affects the elderly or people who are deficient in intrinsic factor. Intrinsic factor is a gastric material that binds to vitamin B-12 and allows it to be absorbed by the body.

The following are signs and symptoms of pernicious anaemia:

  • pale skin
  • weakness
  • weight loss
  • constipation
  • fatigue
  • loss of appetite

High levels of folate in the blood

The level of folic acid in the blood is known as serum folate. High levels of serum folate might disguise the signs and symptoms of vitamin B-12 deficiency, exacerbating the neurological symptoms.

They can also make you more susceptible to anaemia.

Symptoms of other illnesses

Vitamin B-12 levels that are unusually high can be a symptom of liver disease, diabetes, or certain types of leukaemia. The findings of a vitamin B-12 test may be used by a doctor to help them make a diagnosis.

Risk factors

Vitamin B-12 deficiency is more common in some people than in others, especially those with low stomach acid or other digestive problems. Stomach acid helps the body absorb vitamin B-12 more effectively by separating it from meals.

Low vitamin B-12 levels are more common in the following groups of people than in others:

  • people with conditions that reduce vitamin B-12 absorption, including celiac disease and Crohn’s disease
  • people who have had gastric bypass surgery
  • those who are breast-feeding
  • people who are taking medicines such as chloramphenicol, proton pump inhibitors, or H2 blockers
  • older adults
  • children
  • vegans and vegetarians
  • people with diabetes

How does the B-12 vitamin level test work?

Vitamin B-12 status is normally determined by a blood test, but home urine tests are now available. Vitamin B-12 levels can be checked as part of a routine blood test by a doctor.

Although fasting is not required before a B-12 test, it may be necessary if the doctor is utilising the test to check at other blood components.

It is important that patients inform their doctors about any medications or supplements they are taking, as some may have an impact on the outcome.

Acknowledging the results

The following are possible results:

  • Low. Vitamin B-12 levels below 200 pg/mL are considered low. This indicates that you may have a vitamin B-12 deficiency, pernicious anaemia, or an overactive thyroid. Neurological symptoms are common in people who have low vitamin B-12 levels.
  • High. Anything over 900 pg/mL is considered excessively high vitamin B-12 status. This result could indicate problems with the liver or kidneys, diabetes, or certain types of leukaemia.

Because the ranges of results differ from one laboratory to the next, it’s important to talk to a doctor about the results and what they signify.

To rule out vitamin B-12 deficiency, the doctor may measure levels of methylmalonic acid (MMA) and other chemicals. These lab results aid in the early detection of vitamin B-12 deficiency.

Vitamin B-12 deficiency treatment

Vitamin B-12 injections are frequently required by people who have low amounts of the vitamin. These shots are more successful at boosting vitamin B-12 levels than supplements, especially when people have medical issues that make supplements difficult to absorb.

High doses of vitamin B-12 supplements may help some people improve their B-12 status. Supplements are sold in the form of capsules or liquids in pharmacies, supermarkets, health food stores. It may also be beneficial to consume extra vitamin B-12-rich foods.

Treatment for high vitamin B-12 levels

There is no upper limit on vitamin B-12 consumption because high amounts do not cause problems. Having naturally high levels of vitamin B-12 in the body, on the other hand, could be cause for alarm, since it could indicate a serious underlying condition. Doctors will focus on treating the underlying medical condition rather than the vitamin B-12 levels.

Vitamin B-12  foods.

Eggs are rich in vitamin B-12.
Vitamin B-12 is abundant in eggs.

Although low vitamin B-12 levels are frequently caused by absorption problems and other medical conditions, some people may be deficient because they do not acquire enough vitamin B-12 through their food. This is especially true for vegans and vegetarians who have been vegetarian for a long time.

Vitamin B-12-rich foods include:

  • fortified plant-based dairy alternatives
  • fortified breakfast cereals
  • fortified nutritional yeast
  • fish and seafood
  • meat
  • eggs
  • dairy products

Vitamin supplements can help vegans and strict vegetarians make up for dietary deficiencies. Older persons should seek to achieve their vitamin B-12 needs through fortified meals and vitamin supplements, as supplements are simpler for their bodies to absorb than naturally occurring vitamin B-12.

Vitamin B-12 dietary recommendations

Vitamin B-12 is required in 2.4 micrograms (mcg) per day for adults and adolescents over the age of 14. During pregnancy, this rises to 2.6 mcg, and breast-feeding raises it to 2.8 mcg.

Conclusion

Vitamin B-12 is an essential nutrient that is necessary for good health. The status of a person’s vitamin B-12 is determined by a vitamin B-12 level test. This test may be recommended by a doctor to people who have symptoms of a deficiency or who are at risk of having low vitamin B-12 levels in their bodies.

Vitamin B-12 deficiency can be avoided by eating a well-balanced diet that includes many sources of the vitamin on a daily basis, or by taking supplements. If they have trouble absorbing vitamin B-12 from food, oral supplements or injections can help them avoid symptoms and consequences.

Symptoms, stages, causes, and treatment of diabetic nephropathy

Published

on

Diabetic nephropathy is a type of kidney disease that affects people who have diabetes for a long time. It happens when a person’s kidneys are damaged by high blood glucose levels.

Diabetic nephropathy is a type of chronic kidney disease caused by diabetes. The kidneys aid in the regulation of fluid and salt levels in the body, which is critical for blood pressure control and cardiovascular health.

When a person has diabetes, whether type 1 or type 2, or gestational diabetes, their bodies are unable to use or manufacture insulin properly. Gestational diabetes is a kind of diabetes that develops during pregnancy and increases the risk of developing type 2 diabetes later in life.

High blood sugar levels are a symptom of diabetes. High glucose levels can harm several parts of the body over time, including the cardiovascular system and the kidneys. Diabetic nephropathy is the term for the kidney damage that occurs as a result of diabetes.

Diabetic nephropathy is a leading cause of chronic kidney disease and end-stage renal disease in people with diabetes (ESRD). The kidneys in ESRD are no longer able to satisfy the demands of daily life. Kidney failure can occur as a result of ESRD, which can be life-threatening.

This page examines how diabetes affects the kidneys, as well as the treatment options and ways to prevent the risk.

Definition

alzheimer’s patients

Because nephropathy is caused by damage caused by high blood glucose levels, it can affect people with any kind of diabetes.

High blood glucose levels have an effect on the arteries in the body, and the kidneys filter the blood that passes through them.

According to the authors of a 2016 study, 20–40 percent of people with diabetes suffer renal disease.

A person’s tests may reveal one or both of the following:

High levels of albumin in the urine: When the kidneys are in good shape, the urine should include no albumin protein.

A low glomerular filtration rate (GFR): The kidneys’ primary role is to filter the blood. Their ability to do so is hampered by kidney disease. The kidneys should ideally function at 100% or have a GFR of 100Trusted Source. A doctor will not diagnose renal disease unless the GFR is 60 percent or higher. Kidney disease affects 15–60% of the population. Kidney failure is indicated by a percentage of less than 15%.

The end stage of renal disease is ESRD. In the United States, diabetic nephropathy is the most common cause of ESRD. Diabetes is responsible for 40–50% of all occurrences of ESRD, according to Trusted Source. Dialysis will be required if a person has ESRD.

Controlling blood sugar levels can help to lower the risk. Whether you have type 1 or type 2 diabetes, you can lower your risk of diabetic nephropathy by doing the following:

  • blood glucose levels should be monitored and kept within the target range
  • consuming a nutritious, low-sugar, low-salt diet
  • exercising on a regular basis
  • adhering to a treatment plan that may include the use of insulin or other drugs
  • keeping a healthy weight is important.

What is chronic kidney disease? Find out more here.

Causes

Kidney damage puts a strain on these critical organs, preventing them from functioning normally.

When this occurs:

  • the kidneys cannot maintain healthy fluid levels in the body
  • the kidneys cannot remove waste products from the blood
  • the body starts to lose protein through the urine

Diabetic nephropathy takes time to develop. According to one study, 15 years after a diabetes diagnosis, a third of people have high levels of albumin in their urine. Only about half of these people will acquire complete nephritis.

Kidney disease is uncommon in people who have had diabetes for less than ten years, according to statistics. Also, if a person does not get nephropathy 20–25 years after diabetes begins, they have a low probability of developing it later.

Diabetic nephropathy is less likely if a diabetic’s blood glucose levels are well controlled.

Because of the damage to blood vessels, high blood glucose levels raise the risk of high blood pressure. Hypertension, or high blood pressure, can aggravate kidney disease.

Other potential dangers

Other aspects to consider are:

Smoking: A relationship between smoking and increased levels of inflammation may cause kidney injury. While the exact link between smoking and diabetes is unknown, people appear to have a higher risk of diabetes, as well as hypertension and kidney disease.

Age: Kidney disease, particularly a low GFR, is more common in people over the age of 65.

Sex: The condition is more common in men than in women.

Ethnicity, race, or both: African Americans, Native Americans, and Asian Americans are more likely to have it.

Conditions of health: Obesity, chronic inflammation, high blood pressure, insulin resistance, and high blood lipids (fats) are all risk factors for kidney disease.

Some of these risks are or appear to be contributing factors to diabetes or complications.

Diabetic nephropathy is distinct from diabetic neuropathy, a condition that affects the nerve system.

Stages and symptoms

A person with diabetic nephropathy may not experience any symptoms in the early stages. Changes in blood pressure and fluid balance in the body, on the other hand, may already be evident. Waste materials can accumulate in the blood over time, causing symptoms.

Stages

Depending on the GFR, which also measures the proportion of functional kidney function, a clinician may divide renal disease into phases.

Stage 1: Kidney damage is present, but kidney function is normal and the GFR is 90 percent or higher.

Stage 2: Kidney impairment, with some function loss and a GFR of 60–89%.

Stage 3: Mild to severe function loss, with a GFR of 30–59%.

Stage 4: Severe impairment of function with a GFR of 15–29%.

Stage 5: Kidney failure with a GFR of less than 15%.

Symptoms

A person may not detect any symptoms in the early stages. They may feel sick and exhibit the following symptoms at stage 4 or 5:

  • fatigue due to lack of oxygen in the blood
  • nausea or vomiting
  • a metallic taste in the mouth
  • swollen ankles, feet, lower legs, or hands due to water retention
  • darker urine due to blood in the urine
  • shortness of breath

Cardiovascular disease is a complication of late-stage renal disease.

Following a diabetic treatment plan and getting frequent health checks can help a person with diabetes maintain their blood sugar levels, lower their risk of kidney problems, and detect problems early.

A urine test is used to check for proteins in the urine during screening. Protein in the urine, on the other hand, does not always indicate kidney disease; it could also be the result of a urinary tract infection.

Treatment

Diabetic nephropathy can be delayed or prevented with early treatment.

The major goal of treatment is to keep blood glucose and blood pressure under control. This may entail the administration of drugs.

Drug treatment

Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) can help to control blood pressure, protect renal function, and avoid future damage.

In individuals with CKD associated with type 2 diabetes, Kerendia (finerenone) is a prescription drug that can minimize the risk of persistent GFR decline, end-stage renal disease, cardiovascular death, nonfatal myocardial infarction, and hospitalization for heart failure.

In addition, because people with kidney disease generally have low vitamin D levels, a doctor may give vitamin D or a statin to lower cholesterol levels.

For people with type 2 diabetes and CKD, the American College of Cardiology issued guidelines in 2018 supporting the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors or glucagon-like peptide-1 receptor agonists (GLP-1RAs). These medications may lower the risk of CKD progression, heart attacks, or both.

Dietary changes

If you have kidney disease, your doctor may advise you to track the following nutrients:

Water: Although necessary, drinking too much water or fluid can lead to edema and high blood pressure.

Sodium: Because it is a salt component, it might elevate blood pressure.

Protein: Protein can cause waste to build up in the blood, putting extra strain on the kidneys in people who have kidney disease.

Phosphorus: This can be found in a variety of protein and dairy sources. Phosphorus overload can weaken bones and put strain on the kidneys.

Potassium: Potassium levels in people with kidney disease can be greater than they should be, which can harm nerve cells.

Keeping blood sugar levels in check

This is critical for reducing the risk of diabetes complications such as renal disease, cardiovascular disease, and diabetic neuropathy, a nerve system disorder.

These disorders can also lead to additional difficulties. Blood sugar control can also help prevent these problems from arising.

Late-stage treatment options

Diabetic nephropathy can proceed to end-stage renal disease (ESRD), which necessitates dialysis or a kidney transplant. They will very certainly require dialysis for the remainder of their lives or until a kidney donation becomes available.

Dialysis

Kidney dialysis is a process that separates waste items from the blood and removes them from the body using a machine. Dialysis is used to replace a healthy kidney.

Dialysis comes in a variety of forms:

Hemodialysis: Blood is drawn from the body by a needle in the forearm and transported to a dialysis machine via a tube. The blood is filtered outside the body by the machine, then returned through a tube and needle.

Depending on the choice selected, a person may need to do this three to seven times a week and spend two to ten hours per session.

Dialysis can be done at a dialysis facility or at home, and in some cases, overnight alternatives are available. People are increasingly able to incorporate dialysis into their work and personal routines because to flexible choices.

Peritoneal dialysis: The peritoneum, or lining of the abdomen, is used to filter blood inside the body.

  • Dialysis fluid enters the abdomen by a catheter in continuous ambulatory peritoneal dialysis (CAPD). Before draining out, the fluid lingers inside for several hours, filtering waste materials. It takes 30–40 minutes to drain.
  • Continuous cycler-assisted peritoneal dialysis (CCPD), also known as automated peritoneal dialysis, involves a person sleeping linked to a dialysis machine for 8–10 hours. The fluid drainage is controlled by the machine.

Peritoneal dialysis can be done at home, at work, or while traveling. It provides flexibility and gives the individual some control over their condition. If a person is going to travel, for example, they will need to learn how to operate the essential equipment and make sure they have all of the necessary materials.

Kidney transplant

If diabetic nephropathy has progressed to the point where a kidney transplant is necessary and a qualified donor is available, a doctor may propose it. It may take some time to find a donor.

Because a person can live with only one functioning kidney, some people offer to donate a kidney to a loved one.

The individual who receives the kidney, on the other hand, may find that their body rejects the new organ. The body has the best chance of accepting a kidney donation from a family member.

To lessen the risk of the new kidney being rejected by the body, the individual who has had a kidney transplant will need to take medicine. This can have some negative consequences, such as raising the risk of infection.

Financial help

Many people can get financial assistance. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), Medicare and Medicaid normally cover kidney failure treatment.

If all of the following apply, a person can acquire Medicare for ESRD at any age:

  • Their kidneys are no longer functional.
  • They require dialysis on a regular basis or have had a kidney transplant.
  • They have worked for Social Security, the Railroad Retirement Board, or as a government employee for the required amount of time.
  • They are receiving Social Security or Railroad Retirement payments or are eligible for them.
  • They are the dependent kid or spouse of someone who fits one of the aforementioned criteria.

The individual should discuss their options with their insurance provider or their doctor.

Prevention

Controlling blood sugar and blood pressure is the greatest strategy for someone with diabetes to lower their risk of diabetic nephropathy.

This can be aided by making the following lifestyle changes:

  • checking blood glucose levels regularly
  • following any treatment plan their doctor suggests
  • limiting stress where possible
  • eating a nutritious diet that is high in fiber and low in sugar, processed carbohydrates, and salt
  • exercising regularly
  • limiting alcohol intake
  • avoiding tobacco

Learning as much as possible about diabetes and related consequences, such as kidney disease, can make a person feel more confident and in charge of their condition and prevention options.

The National Kidney Disease Education Program of the National Institute of Diabetes and Digestive and Kidney Diseases provides a downloadable record of test results that can assist a person maintain track of their kidney testing and development.

Outlook

The outlook for diabetic nephropathy people will be determined by how well they manage their blood sugar and blood pressure levels, as well as the stage at which they are diagnosed. The sooner therapy begins, the better the outlook.

Diabetic nephropathy can be slowed or stopped with treatment. People with diabetes should have their blood pressure checked as recommended by their doctor and take precautions to prevent kidney disease from worsening.

Exercise-induced hypoglycemia: Things to know

Published

on

The medical name for low blood sugar during or after exercise is exercise-induced hypoglycemia (EIH). The condition can cause itself in a variety of ways, including weakness, shakiness, and extreme exhaustion.

The body’s major source of energy is glucose. The body requires more energy during activity and hence uses more glucose. EIH is caused by an increase in the desire for glucose. Other factors could also be at play.

The symptoms, causes, treatment, and prevention of EIH are all covered in this article. It also covers if EIH is an indication of diabetes and when EIH should be treated.

When to ask assistance

If blood glucose levels go too low, hypoglycemia can be fatal. If you have one or more of the following symptoms, you should get medical help right away:

  • loss of consciousness
  • confusion
  • symptoms that persist despite resting or consuming more food
  • seizure

If people commonly develop EIH or hypoglycemia at other times, they should see a doctor. If the person has diabetes, this could indicate that they are taking too much insulin or that their diabetes medicine dosage is inaccurate.

What is EIH?

Exercise-induced hypoglycemia

Hypoglycemia is a condition in which the blood glucose level is insufficient to supply the body’s energy requirements. Hypoglycemia is defined as a blood glucose level of less than 70 milligrams per deciliter (mg/dl) according to doctors. Most people, however, do not experience hypoglycemia symptoms until their blood glucose levels fall below 55 mg/dl.

Carbohydrates are broken down into glucose by the body. The glucose then enters the bloodstream, prompting the pancreas to produce insulin in response. Insulin aids glucose entry into the body’s cells, allowing it to be used as fuel.

Because active muscles require more fuel, exercise raises glucose demand. Exercise may also make a person more insulin sensitive, which means the insulin works more efficiently and lowers blood glucose levels faster. These factors, when combined, can cause in EIH.

If a person has the following characteristics, they are more prone to develop EIH:

  • have insulin sensitivity or take insulin
  • already have low blood glucose, such as from hunger or from diabetes medication
  • do an intense workout that demands more energy

Symptoms of EIH

Glucose fuels the majority of major bodily activities. As a result, EIH symptoms can vary. The following are some probable signs and symptoms:

  • weakness
  • confusion
  • anxiety
  • fainting
  • shaking
  • dizziness

Hypoglycemia that lasts for a long time or is severe might be fatal. It could result in the following:

Causes

Exercise increases the body’s energy demands, causing it to respond by burning more glucose. People with low glucose levels or those whose bodies metabolize glucose quickly can develop hypoglycemia.

EIH can be caused by a number of reasons, including:

  • exercising immediately after a meal
  • being sick
  • drinking too much alcohol without food
  • using insulin or other diabetes medications
  • not eating enough, or fasting
  • not consuming enough carbohydrates

Exercise causes a significant increase in insulin, which eliminates glucose from the blood, in certain people. Even if a person is well-nourished and does not take blood glucose-lowering drugs, this rise might cause hypoglycemia.

If a person has persistent EIH, a doctor may prescribe medicine to help them recover. Most people, however, can solve the problem by making proper lifestyle modifications.

Is EIH a sign of diabetes?

EIH is not always a symptom of diabetes. Exercise by itself can significantly lower blood glucose levels. People with diabetes, on the other hand, have increased risk factors for hypoglycemia.

Hyperglycemia, or high blood glucose, is a complication of untreated diabetes. If people who take diabetes drugs take more than they need, they are more likely to develop hypoglycemia. It’s also possible that you’re not getting enough nourishment to match your exercise level.

Also, if people with diabetes take diabetic medicine while fasting or commencing a restrictive diet, they may develop hypoglycemia.

Treatment for EIH

Mild EIH normally does not necessitate therapy. In many cases, the condition arises as a result of a person not eating enough food before exercising. Individuals should consume a carbohydrate-rich meal 1–2 hours before a workout to avoid EIH.

Chronic EIH might occasionally indicate a problem with insulin manufacturing. A doctor may administer diazoxide to treat low blood sugar in people who have chronic EIH.

A doctor may consider removing a portion of the pancreas to reduce insulin production in rare circumstances.

Prevention in people with diabetes

People who take diabetic drugs to control their blood glucose levels should check their blood glucose levels before exercising, according to the American Diabetes Association (ADA). If their blood glucose level is below 100 mg/dl, they should consume 15–20 grams (g) of carbs to raise it.

Among the possibilities are:

  • 4 glucose tablets
  • 1 glucose gel tube
  • 1 tablespoon of honey or sugar
  • 4 ounces (oz) of soda or juice

The American Diabetes Association recommends that a person recheck their blood glucose after 15 minutes. If the blood sugar level stays below 100 mg/dl, they should eat another 15 g carbohydrate portion. They should do this every 15 minutes until their blood glucose level reaches at least 100 mg/dl.

Anaerobic exercise, such as high intensity interval training (HIIT), may reduce the incidence of hypoglycemia in people with diabetes, according to a 2019 review. Short bursts of intensive activity are followed by a rest and then another brief burst of intense activity in HIIT.

Prevention in people without diabetes

People without diabetes can usually avoid EIH by doing the following:

  • avoiding drinking alcohol before a workout
  • eating regular meals throughout the day
  • gradually building up to new exercise routines to give the body time to adapt

Stop and take a break if you start to feel unsteady or dizzy throughout your workout. They should drink 4 oz (113 g) of juice or eat a slice of toast before continuing their workout.

Conclusion

Hypoglycemia occurs when blood glucose levels fall too low to meet a person’s body’s energy needs. Hypoglycemia that happens during or after exercise is known as EIH. The condition can affect both people and non-diabetics.

Diabetes patients are more likely to develop EIH, especially if they use insulin or other blood glucose-controlling drugs. In such circumstances, a person should consult a doctor to see whether their drug amounts can be adjusted.

EIH is most commonly caused by not eating enough before exercising or not giving the body enough time to acclimatize to a new exercise schedule in people who do not have diabetes. If a person continues to have regular EIH despite following the necessary precautions, they should seek medical advice to establish the underlying cause.
