Are laxatives good for weight loss?

Published

on

Laxatives are a type of medication used by people to relieve constipation. People without constipation sometimes take laxatives in the belief that these drugs will help them lose weight.

The use of weight loss laxatives is not safe or effective. There are other, more healthy ways to lose weight and maintain the desired body weight.

In this article, we examine whether weight loss aid laxatives. We also discuss the safety of using weight loss laxatives, alternative weight loss strategies, and when to see a doctor.

Does the laxatives cause weight loss?

Does the laxatives cause weight loss?
Taking weight loss laxatives is an unsafe and ineffective strategy.

Doctors do not recommend laxatives as a way of losing weight. Research suggests that while some people mistakenly believe that taking laxatives will prevent their body from absorbing calories, it is an unsafe and inefficient strategy.

Laxatives treat constipation by softening the stool or by stimulating bowel movements. People may assume that passing more stools will result in weight loss.

However, although people may feel “lighter” temporarily, there is no evidence to support the use of laxatives as a safe or effective method of weight loss.

Laxatives cause water loss, not weight loss

The temporary weight loss that people may experience from taking laxatives is actually due to a loss of water. Losing water is not the same thing as losing body fat.

Many laxatives work by helping the intestine to absorb more water from the body or by keeping water in the intestines around the stool. This water softens the stool, making it easier to get through. It can also cause diarrhea, which is a very watery stool.

As this additional water passes through the stool, a person may weigh less when using laxatives. This effect, however, is only temporary.

Laxatives do not reduce body fat or encourage long-term weight loss. Even at high doses, stimulating laxatives that promote the movement of stools through the digestive tract have only a “modest” effect on calorie absorption.

Safety and risks

There are many laxatives available in the constipation treatment counter. Misuse of weight loss laxatives may cause the following side effects:

Diarrhea

People are usually using laxatives to relieve constipation. If a person takes or uses laxatives too often when they are not constipated, these drugs may cause diarrhea.

Some people who frequently use laxatives may experience alternating diarrhea and constipation.

Dehydration

Osmotic laxatives draw water from the body to the intestine to soften the stool. Taking or taking too many osmotic laxatives may cause dehydration.

Other forms of laxatives may also cause frequent diarrhea leading to dehydration.

Common signs of dehydration include:

  • thirst
  • dizziness
  • weakness
  • headaches
  • decreased urination
  • dry mouth

Electrolyte imbalance

Taking laxatives may result in an electrolyte imbalance. Certain types of laxatives may cause the body to absorb high amounts of electrolytes from the intestines, such as sodium and phosphorus. Some laxatives may also lead to low levels of potassium, magnesium, or calcium in the blood.

Electrolyte imbalance can cause weakness and abnormal heart rhythm. In severe cases, having an electrolyte imbalance may be life threatening.

Impaired intestinal function

Some laxatives can stimulate the muscles in the intestine, helping them to promote stool movement. Taking any stimulant laxatives too often may cause dependence.

More research is needed on this effect, but some experts believe that the intestine may become increasingly dependent on stimulation. As a result, it may eventually stop moving food along the digestive tract on its own.

The use of laxatives often may also irritate the intestinal lining, potentially putting a person at risk of having bloody stools.

Time to see a doctor

Achieving and maintaining healthy weight can reduce the risk factors for major health problems, such as heart disease and type 2 diabetes. However, it is vital to lose weight in a safe and sustainable manner.

Sometimes, trying to lose weight can have an adverse effect on a person’s physical and mental well-being. Trying to address negative self-images through weight loss without any mental health strategies can make things worse.

For some people, improper weight loss strategies can lead to eating disorders. Signs and symptoms that may indicate eating disorders include:

  • being preoccupied with weight loss
  • being focused solely on calories, fat content, or carbohydrate content
  • refusing certain food types
  • developing rituals around food
  • skipping meals or reducing portion sizes excessively
  • withdrawing from social activities
  • being overly concerned with body size or shape
  • having mood swings
  • looking in the mirror frequently in a critical way
  • losing or gaining weight rapidly
  • having frequent gastrointestinal problems
  • having trouble concentrating
  • feeling cold all the time
  • having trouble sleeping
  • developing dry or thin skin or hair
  • fainting or feeling dizzy

It is possible to have a few of these symptoms without having a eating disorder. However, anyone who is concerned that they or someone they know may have a eating disorder should talk to a doctor.

Safe weight loss strategies

Exercise is a much safer strategy to lose weight.

Taking laxatives for weight loss is not a safe strategy. Drastic and restrictive diet does not work in the long term for most people.

The most effective way to achieve a healthy weight is to make sustainable lifestyle changes.

  • eating a nutritious, balanced diet that consists mostly of whole foods
  • increasing physical activity each day
  • doing regular exercise
  • practicing self-care to improve body image
  • journaling
  • yoga
  • meditation
  • mindfulness
  • talk therapy
  • cognitive behavioral therapy

Anyone who feels they may need to lose weight should tell a doctor if this is important for their safety. The doctor can advise a person on what is the best range of weight for them. Among other things this range may depend on their height and shape of body.

Conclussion

It is not safe or effective to use the laxatives for weight loss. If a person weighs less after taking laxatives, this is likely due to loss of water.

Loss of water from laxative use is temporary, and is not the same as loss of body fat. Long-term, laxatives don’t decrease body weight.

Laxatives have several potential side effects including fatigue and diarrhea.

Eating a nutritious diet and regular exercise will help a person achieve his or her desired weight. However, before starting a new diet or exercise regimen they should talk to a doctor about whether weight loss is necessary for their health.

Weight loss is only beneficial to the well-being of a person when necessary and they do so safely. Anyone experiencing problems with their body image should seek a doctor’s support, which can help them access the right support.

Descending colon: What you need to know

Published

on

The descending colon is a part of the large intestine. The colon’s left side is the one that descends. It is in charge of keeping the leftovers of digested food until they are eliminated through the rest of the colon and rectum.

The large intestine is involved in nutrient absorption. It also prepares the body’s waste products for removal.

The colon is the section of the large intestine that is the longest. Water and salt are absorbed, and liquid waste is solidified into stool. The ascending, transverse, descending, and sigmoid colons are the four primary parts.

Ulcerative colitis (UC), Crohn’s disease, and colorectal cancer are just a few of the disorders that can impact the function of this section of the digestive tract.

We’ll look at the structure of the descending colon, as well as its function and the disorders that can affect it, in this article.

What is it?

Descending colon

The colon is the largest and longest part of the large intestine, and it is divided into four sections:

  • the sigmoid colon
  • the ascending colon
  • the descending colon
  • the transverse colon

The big intestine is a component of the gastrointestinal tract that connects to the small intestine on one end and the anus on the other.

The descending colon connects the transverse colon to the sigmoid colon and is the third primary portion. It begins from the splenic flexure, or bend, and finishes at the sigmoid colon’s junction. It’s called a retroperitoneal organ because it’s located behind the peritoneum. The peritoneum is the tissue that covers most of the abdominal organs and borders the abdominal wall.

The descending colon measures 10–15 cm in length. It’s in the abdomen’s left lumbar area. This area is located in the middle of the abdomen to the left. In this area, the descending colon runs in front of and down the left kidney.

Function

The descending colon’s major function is to store hardened stool that will eventually empty into the rectum and be removed from the body.

The teniae coli, or smooth muscle bands, produce a series of pouches, or haustra, in all four sections of the colon. The colon appears segmented as a result of this.

The gastrocolic reflex is activated when the colon fills with digested food, causing peristalsis, which is a sequence of wave-like muscular contractions that assist move food along the digestive tract. Food can now pass from the descending colon to the rectum.

The colon’s overall function includes:

  • forming and moving stool forward into the rectum for removal
  • producing and absorbing vitamins
  • absorbing water and electrolytes

Conditions

The function of the descending colon and the colon as a whole may be affected by certain disorders. They may have an effect on the colon’s ability to absorb nutrients and create stool.

The following are some of the most prevalent descending colon health issues:

Crohn’s disease

Another chronic inflammatory disease is Crohn’s disease. It’s an autoimmune condition that can affect any region of the digestive tract, including the colon, from the mouth to the anus.

The skin, joints, bones, eyes, kidneys, and liver are all affected, though the digestive system is the most common. Furthermore, it causes intestinal ulcers, which cause discomfort and pain.

Experts are unsure what causes Crohn’s disease, but they believe it is caused by an aberrant immunological response. Other factors, like as genetics and the environment, could also be at play.

Irritable bowel disease (IBD) includes both UC and Crohn’s disease.

Colonic perforation

A colonic or bowel perforation is a type of gastrointestinal perforation that occurs in the colon.

A cut, tear, or puncture in the colon’s wall can be caused by an injury, but it can also be caused by infection, obstruction, or inflammation.

A colonic perforation causes significant abdominal pain and often necessitates emergency surgery, which may include the removal of a portion of the intestines.

UC

UC is an inflammatory condition that lasts for a long time. It is caused by immune system abnormalities that cause inflammation in the colon.

Ulcers form in the lining of the colon lining as a result of UC. This might cause in stool pain and the urge to stool regularly.

Experts are unsure of the actual cause of UC, however it could be caused by a condition of variables, including:

Colorectal cancer

Cancer that begins in the colon or rectum is known as colorectal cancer. This happens when cancer cells in the colon start to grow out of control.

Colorectal cancers typically begin as polyps on the inner lining of the colon. However, not all polyps become cancerous, and the likelihood of a polyp becoming cancerous varies depending on the type of tumor present.

The size and location of tumors, whether the cancer is recurring, and a person’s overall health will all influence treatment. Among the possibilities are:

Diverticulitis

Diverticulitis is a condition in which small pouches or sacs called diverticula form and push outward through weak areas in the colon wall, causing inflammation.

These protrusions may not always be problematic, but when they get inflamed, they can cause symptoms like:

They can also cause problems including perforation and bleeding.

The following treatments may be used:

  • using antibiotics
  • in some cases, undergoing surgery
  • increasing one’s dietary fiber intake
  • taking pain relief medication

Tips for a healthy colon

People should eat a well-balanced diet, drink lots of water, and exercise regularly to maintain a healthy colon.

The American Cancer Society provides the following colon health recommendations to help minimize the risk of colorectal cancer:

  • reducing consumption of red and processed meats
  • reaching or maintaining a moderate body weight
  • limiting or avoiding alcohol consumption
  • having a diet that is rich in vegetables, fruit, and whole grains
  • quitting smoking
  • exercising
  • increasing dietary fiber intake

Conclusion

The big intestine includes the descending colon. It joins the transverse and sigmoid colon and is used to hold stool before it is emptied into the rectum.

The colon as a whole is responsible for absorbing nutrients from the diet as well as producing and releasing wastes.

IBD, colonic perforation, and diverticulitis are just a few of the health problems that can affect colon function.

Making healthy lifestyle choices, such as eating a balanced diet, exercising regularly, and limiting or avoiding processed meats and alcohol, can help to preserve intestinal health.

What to know about the rectum

Published

on

The rectum connects the colon to the anus at the end of the large intestine. It’s the place where a person keeps their stool before excreting it.

The rectum, also known as the intestinum rectum, is a component of the digestive system that sits at the end of the large intestine. It is a connection between the GI tract and the anus. It sits after the sigmoid colon, the last portion of the colon, and is where the body stores excrement before expulsion.

The function and architecture of the rectum, as well as common disorders that may affect it, will be discussed in this article.

What is it?

rectum

The rectum is the last section of the large intestine closest to the anus, according to the National Cancer Institute. The large intestine is around 5 feet long in total, with the rectum accounting for about 12–15 centimeters of that length.

The intestines employ the muscular walls of the sigmoid colon to push excrement into the rectum when the digestive process is completed. The rectum is where the body stores excrement until it is time to defecate. When the rectum is full, stretch receptors in the wall sense it and stimulate the need to pass stool through the anus.

When to consult a doctor

If a person is having rectal discomfort or any other symptoms that could signal a problem around the anal area, they should see a doctor. Any rectal condition can have a negative impact on a person’s quality of life, so it’s preferable to address the issue as soon as possible to minimize problems. If a person is over the age of 50, they should talk to their doctor about having frequent rectal cancer screenings.

Rectal anatomy

Rectal anatomy

The large intestine is divided into four sections:

  • Cecum: Also known as the ileocecal junction, this section joins the small and large intestines. The cecum helps absorb water and any remaining salts during the digestion process.
  • Colon: The colon is the longest portion of the large intestine. It also absorbs water and electrolytes.
  • Rectum: The rectum stores feces until a person is ready to have a bowel movement.
  • Anal canal: The anus is the final portion of the large intestine. It helps a person have bowel movements.

Between the sigmoid part of the colon and the anal canal is where the rectum is located. The sacral and anorectal flexures are two primary flexures, or bends, in the rectum. There are also three lateral flexures, referred to as the Houston valves. These bends help sustain the weight of excrement while also preventing a strong and sudden urge to defecate.

The rectal ampulla, which connects the rectum to the anal canal, is located at the end of the rectum. The ampulla’s function is to act as a brief holding area for feces before it is released through the anal canal. When the ampulla fills up, the intrarectal pressure forces the walls of the anal canal to swell and expand, allowing excrement to enter.

Common rectal conditions

The following are some of the conditions that might affect the rectum:

Hemorrhoids

Hemorrhoids are enlarged veins in the rectum and anus that protrude. They don’t always create symptoms, but when they do, patients may have the following symptoms:

  • discomfort, irritation, or itching in the anal area
  • pain in the anal area
  • sensitive lumps
  • bleeding during defecation
  • protrusion of skin during bowel movements

Infections

A variety of infections can affect the rectum, causing itching, discomfort, and proctitis, among other unpleasant symptoms.

An individual may contract a sexually transmitted infection (STI) after indulging in anal sex, for example. This can include things like:

Antibiotics can sometimes cause a bacterial infection of the rectum. This is due to the fact that antibiotics can kill the good bacteria that keep pathogens like Clostridioides difficile , away. The germs can then grow out of control and invade the rectum.

Infections of the rectum and rectal tissues can also be caused by the fungus. The following are some examples of fungal diseases:

  • histoplasmosis
  • mucormycosis
  • cryptococcosis
  • candidiasis

Parasites can enter the body and cause disease, especially when cleanliness is poor. Protozoa, which are single-celled organisms, and helminths, which are worms, are the two most common parasitic infections in the bowel. Parasites can cause a variety of issues affecting various parts of the gut, including the rectum.

Anal abscess

A collection of pus in the tissue surrounding the anus or rectum is known as an anal abscess. One usually happens after an illness or an obstruction. A perirectal abscess is a type of rectal abscess that affects roughly 68,000–96,000 persons in the United States each year, according to data. A doctor would usually cut and drain the pus-filled cavity as part of the treatment.

Prolapse

Rectal prolapse occurs when a portion or all of the rectal wall passes through the anal sphincter, the seal that keeps the rectal contents contained. The weakening of the muscles that support the rectum is the most common cause of this illness.

Rectal prolapse can be classified into three categories:

  • External: The entire rectum wall protrudes out of the anus, also known as full-thickness or complete prolapse.
  • Mucosal: Only the mucosa, or anus lining, protrudes through the anus.
  • Internal: Also known as an incomplete prolapse, the rectum folds in on itself but does not protrude out through the anus.

Incontinence

The rectum is vital for managing defecation and maintaining continence because it retains excrement. If a person’s rectum suffers from muscle injury, nerve damage, prolapse, or scarring, it’s possible that the rectum is unable to function properly, causing stool to seep from the anus.

Rectal cancer

Rectal cancer is a disease in which cancer cells grow in the rectum’s tissues. Rectal cancer can cause the following symptoms, which are not always present:

  • bright red blood in stool
  • leaks of diarrhea
  • constipation
  • pain
  • changes in bowel habits

Colon and rectal cancers are the second leading cause of cancer death in the United States. Surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy are all possible treatment options.

Rectal health advice

People can try to practice proper anal hygiene to assist preserve rectal health and prevent rectal disorders. This can involve things like having regular bowel movements and using safer sex. Furthermore, lifestyle adjustments can aid in improving rectal health and lowering the risk of rectal cancer. These can include the following:

  • avoiding alcohol
  • reaching or maintaining a moderate body weight
  • maintaining a nutritious, balanced diet
  • avoiding smoking
  • exercising regularly

Conclusion

The rectum connects the colon to the anus and is the last segment of the large intestine. It’s the place in the body where stool is kept until a person is ready to poop.

The rectal area can be affected by a variety of disorders. By producing pain, discomfort, and incontinence, any of these can lower quality of life. If a person is having problems with their bowels, they should see a doctor for a diagnosis.

Crohn's / IBD

Is there a link between IBD and microplastics?

Published

on

microplastics
A recent study investigates the relationship between microplastics and IBD.

In a recent small-scale investigation, researchers discovered a link between inflammatory bowel disease (IBD) and higher levels of microplastics in feces. The results were published in the journal Environmental Science & Technology.

The study, however, does not prove that microplastics cause IBD. More research is needed to confirm the findings and then seek an explanation for the link.

IBD explained

IBD is a broad term that refers to a variety of gastrointestinal disorders marked by inflammation. Crohn’s disease and ulcerative colitis are the two most frequent kinds.

Diarrhea, rectal bleeding, weight loss, abdominal pain, and exhaustion are all symptoms of IBD.

Researchers aren’t sure what causes IBD, but they believe it starts when a person who is genetically predisposed to the disease is exposed to a specific trigger. More research is needed to determine how important environmental triggers are.

IBD and microplastics

The researchers wanted to discover if there was a link between microplastics and IBD in this new study. Microplastics are present in people’s bodies throughout their lives, yet the health repercussions are unknown.

“We urgently need to know more about the health consequences of microplastics since they are everywhere—including in our drinking water,” says Dr. Maria Neira, WHO director of Public Health, Environment, and Social Determinants of Health.

“Microplastics in drinking water do not appear to constitute a health danger at current levels, based on the limited knowledge we have.” However, we need to learn more. We must also halt the global surge of plastic pollution.”

The current study’s corresponding author is Dr. Yan Zhang. He works at Nanjing University’s School of Environment’s State Key Laboratory of Pollution Control and Resource Reuse, where he previously discovered that microplastics accumulate in the liver, kidney, and intestine in animal models.

He also discovered that the particle size of the microplastics had a significant impact on the accumulation.

“Compelling evidence suggests that microplastics primarily collect in the guts of many species and induce intestinal inflammation and metabolic disturbance,” the researcher told Medical News Today. “Microplastics will inevitably come into contact with humans.”

“Estimating the exposure levels and loads of microplastics in people is crucial for assessing the health risk of microplastics.” However, accurate evidence on the effects of microplastics on humans is still unavailable. Furthermore, the actual health danger of human exposure to microplastics has long been a source of worry.

Fecal samples

Because microplastics are routinely ingested through the gut, the researchers wanted to see if there was a link between microplastics and IBD.

They did this by examining fecal samples from study participants. The researchers gathered 52 persons with IBD and 50 people who were otherwise healthy but did not have IBD.

The participants answered questions on the foods and beverages they consume, their working and living conditions over the past year, the state of their IBD, and their demographic characteristics on a questionnaire.

The scientists then looked at the feces samples to see how much and what kind of microplastics were present.

Microplastics linked to IBD

They discovered that those with IBD had considerably more microplastic in their stools than those who were healthy.

Further research revealed a link between the severity of ulcerative colitis and Crohn’s disease and the number of microplastics present.

The researchers also discovered that persons who had more microplastic in their stool samples drank more bottled water, ate more takeout food, and were exposed to more dust where they lived or worked.

“For the first time, this study reveals that there is a significant difference in the concentration of microplastics in feces from IBD patients and healthy people. Our study also indicates that the characteristics of fecal microplastics are useful to estimate the gut exposure of microplastics.”

– Dr. Yan Zhang

“It’s difficult to say whether microplastics play a role in the development of IBD because it’s a complex systemic disease with an unknown etiology.” People with IBD are more likely to retain microplastics, we suspect.”

The study had flaws as well, the most significant of which was its small size. Before scientists can reach more solid findings, they must perform much larger investigations.

“The concentration of [microplastics] in feces found in this study cannot directly match the concentration of [microplastics] in the gastrointestinal system or in the human body,” the study authors write.

To put it another way, just though people with IBD excrete more microplastic doesn’t mean they have more microplastic in their bodies.
