Types of eczema:

Atopic Dermatits

Contact Dermatits

Dyshidrotic Dermatits

Neuro Dermatits

Nummular Dermatits

Stasis Dermatits

Seborrheic Dermatits

1 Atopic dermatitis :

This is the typical meaning of the term “eczema.” Over 7% of adult Americans are afflicted by the most prevalent kind. It can be brought on by other allergy conditions including hay fever and asthma. It frequently begins in childhood.

2.Contact Dermititis :

This is something that almost everyone encounters in their lifetime. It occurs when something that makes rashes comes into contact with your skin. An allergic reaction or irritation may result from the trigger. Each person has specific triggers, which differ depending on the type of contact dermatitis they have:

A. Irritant Dermatitis : This more prevalent type is more strongly associated with individuals who have atopic dermatitis. Skin care products, soaps and detergents, nickel-containing jewellery, and industrial chemicals like cement and solvents can all be triggers.

B. Allergic Dermatitis : When an allergen comes into touch with your skin, allergic dermatitis flares up. Poison ivy, nickel and other metals, perfumes and fragrance-containing cosmetics, rubber, latex, and the preservative thimerosal are among the common allergies.

3. Dyshidrotic Dermatitis :

This type of eczema is more difficult to treat but is less prevalent. On the sides of the fingers, the soles of the feet, and the palms of the hands, it results in little blister outbreaks. It might be brought on by metals or sweat.

4.Neurodermatitis :

One or two extremely itchy spots, usually on the back of the neck, an arm, or a leg, are typical symptoms of this kind of eczema. Having extremely dry skin or another type of eczema, such as atopic or contact dermatitis, are risk factors. It can also be brought on by certain mental health conditions like obsessive-compulsive disorder (OCD) and anxiety disorder. Compared to other persons, women between the ages of 30 and 50 are more likely to have it.

5.Nummular Dermatitis :

This coin-shaped eczema frequently develops following a burn or insect bite to the skin. If you or any members of your family have asthma, allergies, or atopic dermatitis, you are more likely to develop nummular eczema.

6 Seborrheic Dermatitis :

This occurs in body parts that have a high concentration of oil glands. It’s referred to as dandruff when it’s on your scalp. It is associated with a number of different diseases and several other skin problems, including rosacea, acne, and psoriasis.

7.Stasis Dermatitis :

People with inadequate blood flow, mainly in the lower legs, are more likely to experience this type. These plaques don’t indicate that you have faulty genes, in contrast to certain other types of eczema. Certain lifestyle choices can increase the risk, such as being overweight or not exercising enough.

Factors  Increasing The Risk for Eczema

Stress and genetics are two of the most prevalent risk factors for eczema. However, there are others, such as:

Having very dry skin

Using hair care or skin care products containing allergens.

Allergies to foods.

Living in chilly, damp climates or swampy, hot climates.

Who is more prone to eczema?

If someone in your family has eczema, you are more likely to have it. Although it is not totally hereditary, genes do enhance the possibilities.

Eczema is most common before the age of five, and most children outgrow it.

If you develop eczema as an adult, you are more likely to have it in your twenties or beyond the age of 50.

Atopic dermatitis is more frequent in children, but nummular eczema is more common in adults.

This skin ailment is most frequent in youngsters, although it can also affect adults. According to the National Eczema Association, 10% of the population will have the ailment at some point in their lives.

Eczema may affect anyone at any age. Some races and ethnicities may be more vulnerable than the others:
white individuals 11%
African-Americans 10%
Asian and Pacific Islanders 13 %
Native Americans 13%

Causes of Eczema

Immune System :

Your immune system overreacts to little allergens or irritants (triggers) in your surroundings if you have eczema. Your immune system interprets triggers as foreign invaders, such as germs or viruses, that might cause harm to your body when you come into contact with them. The triggers therefore cause your body’s defence mechanisms to become active. Inflammation is your immune system’s way of protecting you. Your skin develops eczema symptoms due to inflammation.

Genetics :

If your family has a history of dermatitis or eczema, you are more likely to have it yourself. Additionally, if you have a history of allergies, hay fever, or asthma, you are more vulnerable. Common allergens include pollen, pet hair, and foods that provoke an allergic reaction. Another possibility is that you have a genetic mutation that interferes with the normal operation of your skin’s barrier function.

Environment :

Many things in your surroundings have the potential to irritate your skin. Exposure to tobacco, air pollution, harsh soaps, woollen garments, and some skin care products are a few examples. Your skin may become dry and irritated due to low humidity or dry air. Sweating brought on by heat and high humidity can exacerbate your itching.

Emotional :

The state of your skin may be impacted by your mental well-being, potentially leading to a worsening of your eczema symptoms. Eczema flare-ups may occur more frequently in those with high levels of stress, anxiety, or depression.

What triggers Eczema

Some people have itching rash flare-ups in response to factors like:

Fabric or clothing that is rough or harsh

Too hot or too cold?

Soap and detergent are examples of household items.

Animal hair or fur dander

Colds or infections

Sweat from Stress

Symptoms of eczema

Dry, itchy skin: The primary sign of eczema, this condition can be extremely upsetting. When the skin is exposed to irritants like sweat, dust, or wool, the itching may be more intense at night or during those times.

Red, irritated skin: The skin that is impacted may seem bloated, red, and inflamed. Moreover, it could be thickened, scaly, or cracked.

Bump or blisters: Eczema can occasionally result in the formation of tiny bumps or blisters on the skin. These could crust over or ooze.

Thickened skin: The impacted skin may get leathery and thicker over time.

Apart from above mentioned common symptoms of dryness, cracking, redness, and itching. Based on age, certain generalizations can be made, such as : Babies who have an itching rash may develop an oozing, crusting condition that mostly affects the scalp and face. It could also happen on their arms, legs, back, or chest. Newborns may show symptoms within a few weeks or months following birth. Rash most frequently affects youngsters in the elbow bends, behind the knees, on the neck, or on the wrists or ankles of young people. The rash turns scaly and dry. When it comes to grownups Usually affected areas include the face, hands, feet, wrists, and backs of the knees.

Most likely, you’ll have extremely dry, thick, or scaly skin. These spots in fair-skinned individuals may begin crimson and subsequently turn brown. Eczema can alter skin pigmentation in those with darker complexion, lightening or darkening the afflicted area.

How is Eczema Diagnosed ?

Eczema diagnosis isn’t always straightforward, often requiring a dermatologist’s expertise. Typically, it starts with a detailed discussion of your medical history and symptoms, focusing on itch, rash location, and potential triggers. Your skin will undergo a thorough examination, looking for dryness, redness, scaling, and thickening.

Sometimes, additional tests like allergy skin prick tests or patch tests might be needed to pinpoint allergens. In rare cases, a tiny skin sample (biopsy) may be taken for lab analysis to rule out other conditions. While there’s no single “eczema test,” piecing together these clues allows your dermatologist to confidently diagnose and tailor a treatment plan for your unique case.

On Positive Diagnoses Ask Your Doctor the following questions:

Can I still workout if sweating makes things worse?

What happens if my symptoms don’t improve or if I acquire an infection from scratching?

Is it true that stress causes flare-ups?

Is it usual to go for lengthy periods of time without experiencing symptoms?

What is the best approach to moisturise my skin? Can I take over-the-counter medications, or do I require a prescription?

Is it necessary to purchase specialised soaps, lotions, and laundry detergent? Are fragrance-free or sensitive-skin products beneficial?

Is there anything I should avoid to keep flares at bay?

Is there anything I shouldn’t wear? What materials should I wear?

Do pets aggravate symptoms?

Is there anything I can do to treat my skin to lessen the possibilities of another flare-up?

Sleep issues. Because of the irritation, eczema can induce these.

Foods To Avoid

While specific triggers differ among individuals, certain foods are notorious for causing eczema flare-ups. Dairy tops the list, with cow’s milk protein a common culprit. Its inflammatory properties can worsen itching and redness.

Eggs also deserve a raised eyebrow, especially for those with allergies. Their proteins can trigger eczema symptoms in both children and adults.

Soybeans lurk in many processed foods, and their high isoflavone content can mimic estrogen, potentially aggravating eczema. Even seemingly healthy citrus fruits like oranges and grapefruits can be problematic. Their acidity can irritate sensitive skin, especially when applied directly.

Gluten, the protein found in wheat, barley, and rye, can worsen eczema in individuals with gluten sensitivity. Though not a true allergy, gluten can trigger inflammatory responses that manifest as skin problems.

Spicy foods might tantalize your taste buds, but they can wreak havoc on eczema. Compounds like capsaicin, found in chili peppers, trigger the release of histamine, a chemical that dilates blood vessels and worsens inflammation.

Remember, this isn’t an exhaustive list. Food sensitivities are highly personal, and what triggers one person’s eczema might be perfectly fine for another. Keeping a food diary to track your intake and flare-ups can be a detective’s game, but ultimately empowering in identifying your unique triggers and navigating an eczema-friendly diet.
