Atopic Dermatitis / Eczema

What causes rashes on the inner thighs

Published

on

A rash is a fairly common complaint on the inner thigh. The lack of heat and ventilation around the inner thighs enables the flourishing of bacteria and other germs. Often, this region is easily irritated by friction or clothing contact.

This page outlines 11 common causes, along with potential treatment methods and preventive strategies, of a rash on the inner thigh.

Causes

There are a variety of potential causes for a rash in the inner thigh. While the causes can differ between the sexes, both women and men are prone to inner thigh rashes.

Potential causes include:

1. Atopic dermatitis

A rash on the inner thigh
A rash on the inner thigh may be accompanied by itchiness, oozing lesions, and scaly patches.

Red, itchy, and dry skin is caused by atopic dermatitis, more commonly known as eczema. In children, the condition is more common, although it can occur at any age.

An estimated 10 percent to 20 percent of children worldwide have eczema, according to the American Academy of Dermatology Association, while only 1 to 3 percent of adults do.

In the creases of the elbows or knees, eczema may start, but it sometimes spreads to other areas of the body, including the inner thighs.

Over time, this skin condition may cause:

  • a leathery appearance
  • Skin with dry skin
  • Skin lightening or darkening
  • Perpetual Bumps

2. Chafing

As they may rub against each other or be irritated by clothing and pantyhose, the inner thighs are particularly prone to chafing. Physical activities, such as running, can lead to chafing as well.

Chafing is marked by redness and blistering, but if the cause of the chafing is treated, those symptoms should clear up.

3. Contact dermatitis

Upon skin exposure to an irritant (irritant contact dermatitis) or an allergen (allergic contact dermatitis), contact dermatitis causes a rash to flare up.

A number of substances can be caused by irritant contact dermatitis, including:

  • bleach
  • detergents
  • fragrances
  • soap

Allergic contact dermatitis is less common and results from exposure to substances such as:

  • latex
  • nickel
  • poison ivy

The inner thighs may be particularly vulnerable to contact dermatitis because, on a daily basis, they come into close contact with clothing and detergents.

4. Heat rash

Heat rash, also called miliaria or prickly heat, happens when the pores are blocked and the skin’s sweat is trapped. Although this skin rash can be itchy and unpleasant, it is not harmful.

It appears as small bumps on the skin and can affect any area of the body, from the groin and inner thighs to the back and chest. Typically, signs resolve once the skin cools down.

In hot and humid conditions, heat rash occurs and affects babies, children, and people on bedrest most commonly.

5. Hidradenitis suppurativa

Hidradenitis suppurative (HS) is a rare rash that may burst and ooze pus under the skin as blackheads or pimple-like bumps. It happens when the skin rubs against the skin, so in the inner thighs, groin, and armpits it is prevalent.

The cause of HS is unknown, but it is most common in people who:

  • have excess weight or obesity
  • smoke
  • have depressionanxiety, or both
  • have diabetes, metabolic syndrome, or both
  • have follicular occlusion tetrad, a syndrome that combines HS with acne conglobata and dissecting cellulitis of the scalp
  • have squamous cell carcinoma in the affected areas

According to the American Academy of Dermatology, HS affects three times more women than males, and it typically starts during puberty and menopause.

6. Jock itch

Despite the term, not just athletes, everybody can get a jock itch. It is more prevalent in men than in women because, especially around the groin, men tend to sweat more.

Jock itch, caused by the same fungus that leads to the foot of the athlete, can itch, burn, and cause a flaky and scaly rash on the genitals, inner thighs, and buttocks.

This rash, particularly through direct contact or through sharing towels or other objects, is highly contagious.

7. Pityriasis rosea

A doctor with his patient
Rashes that get worse or do not fade after a couple of weeks should be assessed by a doctor.

In the spring and fall, this common rash sometimes occurs, with symptoms including small, scaly patches on the thighs, neck, upper arms, back, or chest.

Approximately 75% of all pityriasis rosea cases begin with a “herald patch,” which is a single oval, scaly patch, accompanied by more patches within 2 weeks.

In younger people, the condition affects women more than men and is more common. Rarely does it affect those over 60.

The cause of rosea pityriasis is not known, but within a few months, the rash normally disappears completely.

8. Razor burn

Razor burn is caused by shaving, especially with unclean or dull razor blades, or when improper methods of shaving are used.

On any part of the body that is shaved, Razor Burn may develop.

9. Swimmer’s itch

Swimmer’s itch is an allergic reaction to some parasites that reside in certain lakes , ponds, and oceans, medically referred to as cercarial dermatitis.

Symptoms include skin tingling or burning, reddish pimples, and small blisters that occur in infected water within days of swimming. Unless symptoms persist or get worse, most cases do not need medical attention.

Swimmer’s itch can occur anywhere in the world, but during the summer months, it occurs more frequently. There is, however, no chance of scratching from properly chlorinated pools for swimmers.

Symptoms

A rash in other parts of the body resembles rashes on the inner thigh. Symptoms following this may include:

  • blisters
  • burning sensations
  • discomfort
  • itchiness
  • oozing from the lesions
  • pain
  • red bumps
  • scaly patches

If the thighs rub together or if a person is wearing tight clothing on the legs, the rash may become more irritated.

STIs and inner thigh rashes

A rash on the inner thigh can be caused by certain sexually transmitted infections ( STIs). They include:

10. Genital herpes

More than 1 in 6 Americans aged between 14 and 49 years have genital herpes. There is no cure for the disease, and there are no symptoms for many individuals with the infection, but they can also spread STI to others.

Symptoms include red bumps or blisters on the genitals, buttocks, and inner thighs that are itchy and painful.

11. Secondary syphilis

In its early stages, syphilis is easy to treat, but when left untreated, it can lead to severe complications.

Sores around the genitals or anus provide the initial signs. Its symptoms include fever and skin rash at the second stage , known as secondary syphilis, which can appear on any part of the body, including the inner thighs.

Diagnosis

An individual should see a doctor if the rash is followed by other symptoms, such as fever or pain.

Diagnosis of the underlying cause of a rash on the inner thighs is based on:

  • a visual examination of the rash
  • a person’s medical history
  • any other symptoms

A sample of the rash can be submitted for further testing in some cases. A dermatologist (a doctor who specializes in skin disorders) may be recommended to certain individuals.

Treatment

The therapy prescribed will depend on the cause of the rash. Not all rashes, as they may clear up on their own, may require intervention.

When treatment is necessary, options include:

Medications

Several medications are available to treat a rash on the inner thigh, including:

  • antibiotics for some STDs and other infections
  • antifungals for cases of jock itch
  • antihistamines for itching
  • topical or oral steroids to decrease inflammation

Home remedies

An oatmeal bath may help to soothe the symptoms of a rash.

One or more of the following home remedies can help, depending on the type of inner thigh rash:

  • Cold compress. Placing a cool, wet compress on the rash can reduce itching and inflammation. Gently pat the skin dry after use. Repeat as often as necessary.
  • Oatmeal bath. Oatmeal is a common remedy for skin complaints. Research suggests that it has antioxidant and anti-inflammatory properties that may soothe itchy and irritated skin.
  • Tea tree oil. Some research suggests that tea tree oil is more effective in controlling allergic contact dermatitis than other treatments, such as zinc oxide and clobetasone butyrate. It was not shown to be effective for irritant contact dermatitis. Tea tree oil can be added to a cold compress or applied to the skin if diluted with a carrier oil.
  • Natural astringents. Some people use natural astringents to ease the symptoms of razor burn and other itchy rashes.
  • Avoid irritants and allergens. Rashes that are caused by contact dermatitis will often clear up once the irritating substance is removed.

Prevention

To avoid getting an inner thigh rash:

  • Stay cool. Hot, sweaty skin can provide a breeding ground for bacteria or fungi. It can also cause heat rash.
  • Keep the skin dry. Drying the skin thoroughly after bathing and removing sweaty clothes after workouts can help prevent a rash.
  • Shower with temperate water. Water that is too hot may cause heat rash or make other skin conditions worse.
  • Maintain a healthy weight. Certain rashes, including those caused by chafing, are more common in people who are overweight.
  • Avoid sharing towels. The risk of getting certain contagious conditions, including jock itch, can be reduced by not sharing towels, clothing, and other items.
  • Use proper shaving techniques. Avoid using dull or dirty blades, never dry shave, and always shave in the direction of hair growth.
  • Quit smoking. Tobacco use can increase the risk of getting certain rashes, such as hidradenitis suppurativa.
  • Abstain or take care with sex. Reduce the risk of getting an STI by using latex condoms, getting tested regularly for STIs, and ensuring all sexual partners have also been recently tested and are STI-free. Note that condoms cannot fully protect against genital herpes or syphilis.

Outlook

A rash is a common symptom on the inner thigh that can have several underlying causes. Most cases of inner thigh rash are not serious, but in order to ascertain the exact cause and to obtain adequate treatment, it is necessary to see a doctor.

An inner thigh rash can be easily treated with many medical and home remedies. Some rashes do not need any therapy at all, but with time they can resolve on their own.

In addition, in the first instance, several cases of inner thigh rash can be prevented by using the preventive techniques mentioned above.

Atopic Dermatitis / Eczema

Varicose eczema: All you should know

Published

on

Stasis dermatitis, often known as varicose eczema, is a kind of eczema that affects people who have varicose veins. It occurs as a result of inadequate circulation. It commonly affects the lower legs, with sores developing as a result.

Other names for the same condition include gravitational dermatitis and venous eczema.

Adults are more likely to experience it, especially if they are overweight. According to studies, it affects 20% of people over the age of 70.

Symptoms

Poor circulation causes a skin condition called statis dermatitis.
Poor circulation causes a skin condition called statis dermatitis.

When blood flow in the lower legs is impaired, the valves in the veins weaken, allowing blood to leak into body tissues, stasis dermatitis develops.

This is known as venous insufficiency, and it can lead to the development of stasis dermatitis symptoms.

Initially, the symptoms will be felt in the ankles. There might be:

  • Swelling that appears toward the end of the day and lessens after sleeping overnight
  • Varicose veins covered with dry, itchy, or irritated skin
  • Red, swollen, and painful skin, which may be weeping and crusty
  • Heavy or aching legs when standing for a prolonged period

Other symptoms develop when the disorders go upward to the calf of the leg.

These include:

  • Purple or red sores, or venous ulcers, on the lower legs and the tops of the feet
  • Skin that is dry, cracked, shiny, and itchy

Sores that leak and crust become scaly on the skin. Bacterial infection and skin color changes are possible. Scabs and scars emerge when the wounds heal.

Eczema can affect other parts of the body in certain people.

If left untreated, the condition might deteriorate over time.

This can result in:

  • Deeply pigmented skin
  • Red and scaly skin in the affected area
  • Intense itching in the skin
  • Hard areas of thickened, fibrotic skin
  • Shrinking of the lower part of the leg

The situation may then get much more complicated.

Bacterial infection can infiltrate the skin through the gaps and poor skin condition. Cellulitis can develop in the leg and spread throughout it. Cellulitis is an illness that affects the deeper tissues of the body.

The combination of the effects of stasis dermatitis on the skin and the usage of various drugs can make it exceedingly sensitive and painful to touch. Contact dermatitis is the medical term for this condition.

Risk factors and causes

varicose veins
Varicose eczema is more common in people who have varicose veins.

Blood can be pushed upward toward the heart through valves in the legs. These valves fail as people age, allowing blood to flow out and pool in the lower leg, resulting in swelling and a condition known as venous insufficiency.

Blood leakage and cell death can result from these circulation issues, which can contribute to stasis dermatitis.

Those who have, or have had, the following conditions are at a higher risk:

The following are some lifestyle aspects to consider:

  • Excess body fat
  • A lack of exercise
  • Standing or sitting for a long time, for example, at work

People who are overweight or obese, as well as women who have had many pregnancies, are at a higher risk. The veins in the legs are strained even more as a result of extra weight during pregnancy.

Diagnosis

A physical examination will be performed by the doctor. The condition will be indicated by obvious signs and symptoms. They’ll inquire about the patient’s past medical history, including blood clots, surgery, heart disease, and previous damage to the afflicted area.

Tests may be performed to determine the cause of poor circulation.

These may include the following:

  • Heart function tests
  • Ultrasound to detect any blood flow problems
  • Blood tests

Because a person with stasis dermatitis is more likely to develop a skin allergy, allergy testing may be performed.

Treatment

Treatment will focus on relieving the symptoms.

  • Swelling can be reduced and circulation improved by compression stockings or dressings. The patient’s legs should likewise be lifted above the level of their heart.
  • Raising the legs can be beneficial. The American Academy of Dermatology (AAD) recommends that patients elevate their legs for 15 minutes every 2 hours and sleep with them propped up on a pillow.
  • To minimize inflammation, including redness, swelling, and discomfort, a corticosteroid or a topic calcineurin inhibitor (TCI) may be administered.
  • Special dressings may be required for ulcers or weeping sores. The dressing must be changed every 2 to 3 days at first, but after that, once or twice a week will enough.
  • Cellulitis, erosions and ulcers, and other forms of infection will necessitate the use of antibiotics. A skin graft may be required for a big ulcer.
  • Itching can be relieved with antihistamines.
  • Moisturizers and emollients can aid in the prevention of dry skin. The ADD suggests using petroleum jelly or a thick lotion that says “fragrance free” on the label. Options might be discussed with a doctor, dermatologist, or pharmacist.
  • Varicose veins, which cause pain, irritation, and ulcers, can be removed by surgery.

If your skin gets discolored, a dermatologist can help you find ways to lighten it.

Management and prevention

sitting for long
Long durations of sitting or standing increase the risk.

The majority of people who have stasis dermatitis will have it for the remainder of their lives.

The following steps are included in the treatment of the condition:

  • Using medication for skin care and when symptoms flare up
  • Keeping the legs raised when possible
  • Using compression stockings

Stasis dermatitis may be avoided by taking care of the legs.

Among the measures are:

  • Avoiding bath products and soaps that dry the skin
  • Using emollients or moisturizers to keep the skin supple
  • Not standing or sitting for prolonged periods

Stasis dermatitis and a variety of other illnesses can be avoided by leading a healthy lifestyle that includes exercise and a well-balanced diet.

Atopic Dermatitis / Eczema

Does Dead Sea salt help with eczema?

Published

on

For ages, people have bathed in the Dead Sea for medicinal purposes. People may now buy Dead Sea salt and utilize it at home. According to a few studies, this may help with eczema.

A prior study from 2011 revealed that a topical lotion mixed with Dead Sea minerals enhanced the skin barrier function in 86 children with eczema. However, there is currently no larger-scale research available.

People who want to try Dead Sea salt for eczema can buy the salts to dissolve in baths or use topical treatments containing the minerals.

Continue reading to find more about how and why Dead Sea salt could help with eczema, whether there are any hazards, and how to use it.

What is dead sea salt, and how does it work?

The Dead Sea is the lowest point on the planet and the world’s saltiest body of water. It has a long history of being thought to have medicinal powers.

Scientists are still attempting to figure out if and how it helps with certain ailments.

The Dead Sea water contains a variety of minerals, including:

Salt may be made by evaporating water from the Dead Sea, which includes these minerals. These salts are subsequently used in goods like bath salts, body lotions, and soaps by some corporations. Dead Sea mud is used in other goods.

Is Dead Sea salt good for eczema?

There hasn’t been much research on whether Dead Sea salt can help with eczema. Two studies, however, suggest that it may be advantageous.

Dead Sea salt bathing

A 2005 scientific experiment looked at the effects of swimming in Dead Sea water containing magnesium chloride on people with atopic dermatitis, a kind of eczema.

For 15 minutes, research participants dipped one forearm in a water solution containing 5% Dead Sea salts. They dipped the second arm in the sink.

The researchers evaluated their skin quality at the start of the trial and once a week for the next six weeks. They found that individuals who soaked their skin in Dead Sea salts had greater skin hydration and less symptoms of roughness and irritation at the conclusion of the trial.

Dead Sea salt cream

An prior clinical experiment from 2011 looked at the benefits of a Dead Sea mineral-enriched lotion on children with mild to moderate atopic dermatitis.

The participants were divided into three groups for the study. For 12 weeks, all groups applied a cream to their entire bodies twice daily, in the morning and evening. Each group, however, utilized a cream that included different ingredients:

  • One cream was a simple emollient moisturizer with no ingredients from the Dead Sea.
  • One cream contained Dead Sea water.
  • One cream contained Dead Sea mud.

The group that used the Dead Sea water cream had the greatest outcomes of all the groups. Over the course of the 12 weeks, this cream had the most favorable impact on the skin barrier. Improvements were seen in the other groups as well, but they were not as significant.

How might Dead Sea salt help with eczema?

The possible advantages of Dead Sea salt for eczema are thought to be owing to its mineral content, according to researchers.

The authors of the 2005 research hypothesize that the therapeutic impact of Dead Sea salt was due to magnesium, which may assist bind water to the skin and aid in skin restoration.

According to a 2020 research, the high magnesium content of Dead Sea salt contributes to its therapeutic characteristics. Magnesium, according to the authors, can:

  • promote skin barrier integrity
  • reduce inflammation
  • boost water retention in the skin

Zinc, which is used in numerous skin healing treatments due to its propensity to aid wound healing, is also found in Dead Sea salt.

Is there a danger in utilizing Dead Sea salt?

The subjects in the 2005 and 2011 investigations tolerated the Dead Sea minerals well. This component by itself is unlikely to cause negative effects in otherwise healthy people. There are, nevertheless, certain possible dangers.

Balneotherapy is the practice of bathing in mineral water. In general, this is a safe procedure with little adverse effects. These can include the following:

  • exfoliative dermatitis, which refers to the shedding of the top skin layer
  • infections
  • low blood pressure and fainting with prolonged immersion
  • skin irritation
  • itching

If a person uses Dead Sea salts at home, however, negative effects are less likely to occur since they may control how concentrated and hot the water is. Water that is extremely salty or extremely hot can be drying.

The Dead Sea has a high concentration of salt, around 34 percent. The 2005 research, on the other hand, only utilized a 5% concentration and still found a favorable impact.

Balneotherapy should not be used by some people. This comprises people with the following conditions:

  • severe anemia
  • an impaired sense of balance
  • drug or alcohol intoxication
  • a recent stroke or heart attack
  • open wounds
  • skin infections
  • acute arthritis or other acute inflammatory conditions
  • a current atopic dermatitis flare-up
  • weeping lesions
  • blisters or ulcers
  • pustular or erythrodermic psoriasis
  • epilepsy
  • cardiovascular disease
  • severe high or low blood pressure

Before adopting any home remedies for eczema, people should always see a doctor, since they are not good for everyone.

Best way to use Dead Sea salt for eczema

If your doctor thinks it’s okay, there are numerous methods to sample Dead Sea salt. People can take a bath with the salt or use topical items containing Dead Sea salt, water, or mud.

To use the salt in a bath, follow these instructions:

  1. Run a bath of warm, but not hot, water. For balneotherapy, the water temperature is usually in the range of 86–104°F (30–40°C).
  2. Add 1 cup of Dead Sea salts to the water and allow them to dissolve.
  3. Get into the bath and stay in the water for a short time. The National Eczema Association recommends that people with eczema limit baths to 5–10 minutes.
  4. After leaving the bath, pat the skin dry with a clean towel. Try not to rub or scratch the eczema.
  5. Gently apply an emollient to the skin immediately afterward.

If a person just has eczema on one part of their body, such as their feet or hands, Dead Sea salts can be used in a mini bath that specifically treats those regions. However, the salt should not be used as a scrub since it might irritate eczema-affected skin.

Another alternative is to use fragrance-free Dead Sea mineral creams or lotions on the skin. This should be done after washing to ensure that the cream remains on the skin as long as feasible.

Other natural solutions

There are several additional natural therapies that may assist with eczema in addition to Dead Sea salts. These are some of them:

  • Colloidal oatmeal: Colloidal oatmeal can be added to bathwater to help reduce itching. Alternatively, you may form a paste and use it as a therapy on your skin before washing it off.
  • Vinegar: Vinegar straight from the bottle is far too abrasive for skin application. Vinegar, when diluted in a safe amount of water, can assist in the killing of germs. To a full bath, people can add 1 cup to 1 pint (236–568 milliliters).
  • Coconut oil: According to research, coconut oil decreases the number of Staphylococcus germs on the skin, lowering the risk of eczema infection. Apply virgin or cold-pressed coconut oil to wet skin once or twice a day to attempt this cure.

Conclusion

According to a few studies, Dead Sea salt may help enhance the skin barrier’s function and minimize the obvious indications of eczema. Minerals like magnesium and zinc may have a role in the benefits. More current and large-scale research, however, are required to prove this.

There is now no proof that it performs better than medical therapies, although it may be a valuable complement to people’s eczema treatment regimens.

Despite the fact that Dead Sea salt is typically safe, it may not be suitable for everyone. Before using, a person should consult with a doctor.

Allergy

Is eczema considered an autoimmune disease?

Published

on

Eczema is a blanket word that refers to a variety of inflammatory skin disorders, often known as dermatitis. Several kinds of dermatitis are caused by an immune system response, and some evidence shows that autoimmunity may play a role.

An autoimmune disease occurs when the immune system attacks the body’s healthy tissues by mistake. This is often distinct from other forms of immune responses, such as an allergic reaction, which occurs when the body considers a specific substance to be a threat.

However, according to research published in the Journal of Autoimmunity, atopic dermatitis (AD) can begin as an allergic reaction and proceed to an autoimmune response.

What is eczema?

eczema

Eczema is a term used to describe a collection of skin disorders that create itchy, inflammatory rashes. Eczema can show in red spots on people with light skin tones. On darker skin tones, the patches may appear brown, purple, or gray.

There are now seven forms of eczema recognized by doctors:

  • contact dermatitis
  • atopic dermatitis
  • stasis dermatitis
  • dyshidrotic eczema
  • seborrheic dermatitis
  • nummular eczema
  • neurodermatitis

The immune system appears to be linked to most kinds of eczema, although the data is limited.

This article examines the putative relationships between autoimmunity and three forms of eczema: atopic, dyshidrotic, and nummular eczema.

Is atopic dermatitis an autoimmune disease?

According to the American Academy of Dermatology Association, (AD) is a prevalent type of eczema with no clear etiology. Researchers believe that Alzheimer’s disease develops as a result of a combination of genetics, a weak immune system, and environmental factors that cause symptoms. Autoimmunity may also have a role, according to some studies.

According to dermatologists, patients with Alzheimer’s disease have a hereditary characteristic that causes their skin to lose moisture too fast, leaving breaches in the skin barrier. This might result in dry, unprotected skin.

This isn’t necessarily enough to produce Alzheimer’s disease. Other variables that may increase the likelihood of getting the illness in persons who are susceptible to it include:

  • living somewhere that is cold and damp for at least some of the year
  • exposure to pollution and tobacco smoke
  • stress

Autoimmunity may possibly play a role in Alzheimer’s disease. According to the authors of a research published in 2021, Alzheimer’s disease may begin as an allergic reaction before evolving to an autoimmune response. They believe that persistent inflammation and relapses are caused by this.

A major population-based research from 2021 discovered that patients with one or more autoimmune conditions, particularly those affecting the skin and digestive tract, have a greater risk of Alzheimer’s disease. This shows that one may cause or enhance the risk of the other.

More study on how Alzheimer ‘s disease develops, however, is needed to clarify whether it is an autoimmune disease and, if so, what therapies could assist.

Is dyshidrotic eczema an autoimmune disease?

Small, irritating blisters appear on the soles, palms, and margins of the fingers and toes in dyshidrotic eczema, also known as pompholyx. Although the reason is unknown, many people who suffer from it also have another kind of eczema. Doctors have also discovered that dyshidrotic eczema may run in families.

The following are some of the most prevalent causes of flare-ups:

  • metal allergies, especially nickel allergy
  • seasonal allergies, such as hay fever
  • heat and humidity
  • stress

Because there have been few research on the immune response in persons with dyshidrotic eczema, it’s uncertain if it’s autoimmune.

Is nummular eczema an autoimmune disease?

Nummular eczema is characterized by coin-shaped areas that are itchy and occasionally oozing. Patches can occur on any part of the body. Experts are unsure what causes nummular eczema, although they believe it has something to do with:

  • having dry or sensitive skin
  • having other types of eczema
  • metal allergies
  • cuts, insect bites, or chemical burns
  • low blood flow in the legs, if the patches appear there

Can eczema be a symptom of other autoimmune diseases?

Eczema and skin rashes are common symptoms of autoimmune diseases, however none of these symptoms alone would prompt a clinician to suspect an autoimmune illness. Eczema is a common skin condition that can develop on its own.

Eczema and autoimmune diseases can coexist, and the one can exacerbate the other. Eczema can be made worse by conditions that make the immune system more sensitive or cause inflammation.

Additionally, eczema can develop as a side effect of an autoimmune disorder. Inflammatory bowel disease (IBD), for example, can make it difficult to absorb nutrients.

According to a 2012 research, if certain nutrients, such as essential fatty acids, are deficient, the skin might become dry and prone to eczema.

Skin problems can potentially be an adverse effect of autoimmune disease therapy. For example, one of the drugs used to treat Crohn’s disease, infliximab (Remicade), can induce eczema.

According to a 2015 research, after taking this medicine, 29.6% of patients acquired scaling eczema and 18.5 percent had aggravated atopic eczema.

What other factors contribute to eczema?

Other causes, in addition to autoimmunity, can stimulate the immune system, including:

  • allergens
  • irritants, such as artificial fragrance, harsh cleaning products, or smoke
  • friction on the skin from itchy fabrics
  • certain bacteria, viruses, and yeast
  • dysbiosis, which is when the microbiome in the gut or on the skin is imbalanced

Symptoms can also be caused by things that decrease the skin’s capacity to moisturize and defend itself. Frequent hand washing, alcohol hand sanitizer usage, and hot showers, for example, can promote skin dryness. After having the skin wet, moisturizing it or applying sanitizers with moisturizers can assist.

Some of these variables have a greater impact on specific forms of eczema than others. Experts believe that seborrheic dermatitis is caused by a kind of yeast known as Malassezia.

This yeast thrives on the skin, but if it becomes too large, it might cause an immunological reaction. It may be controlled using antifungal treatments and shampoos.

To understand the causes of eczema and provide the appropriate therapies, doctors must first diagnose the precise form of eczema. People might have many types of eczema in different parts of their body, requiring different treatments.

Eczema can appear a lot like other skin illnesses including infections, psoriasis, and actinic keratosis, which is a precancerous skin rash.

If you haven’t received an official diagnosis or if conventional eczema treatments aren’t working, consult a dermatologist.

Conclusion

Eczema is a catch-all word for a group of seven inflammatory and itchy skin disorders. Each is unique and can be triggered in a variety of ways.

Some data, however, shows that autoimmunity may play a role in Alzheimer’s disease. Environmental factors, genetics, and a family history of allergies and asthma can all increase the risk.

More study into Alzheimer’s disease might lead to new medicines that tackle the underlying process.

Consult an eczema specialist for a diagnosis and treatment options that can help you manage your symptoms.
