Generalized Eczema

Eczema, also known as dermatitis, is a skin condition that causes the skin to become red, itchy, and inflamed. Eczema dermatitis is a skin condition characterized by red, itchy, and inflamed patches of skin. It’s a common health problem affecting millions of people globally. There are several types of eczema, each with its distinct characteristics and triggers.

Types

1. Atopic Dermatitis:

Atopic dermatitis is the most common form of eczema. Often starting in childhood, it is linked to a group of conditions that include asthma and hay fever. This type of eczema creates a vicious cycle: dry skin becomes incredibly itchy, and scratching leads to redness and inflammation, which leads to even more itching and discomfort.

2. Contact Dermatitis:

Contact dermatitis develops when the skin touches a substance that causes an allergic reaction or irritates the skin. This form of eczema is often the result of exposure to things like harsh soaps, detergents, or certain metals in jewelry.

3. Dyshidrotic Eczema:

Dyshidrotic eczema is characterized by small, itchy blisters on the hands and feet. It tends to appear during certain seasons (like spring and summer) or during times of stress. If you’ve noticed these symptoms, you may be dealing with dyshidrotic eczema.

4. Nummular Eczema:

Nummular eczema, also known as discoid eczema, manifests as round, coin-shaped spots on the skin. These spots can be very itchy and may become dry and scaly. They can appear anywhere on the body but are most commonly found on the legs and buttocks.

5. Seborrheic Dermatitis:

Seborrheic dermatitis is a type of eczema that primarily affects the scalp but can also appear on oily areas of the body, such as the face and chest. It causes red, scaly patches, and can sometimes lead to dandruff.

6. Stasis Dermatitis:

Stasis dermatitis is a skin irritation on the lower legs, generally related to circulatory problems. It’s more common in middle-aged and elderly people and can cause the skin to become discolored, itchy, and sometimes painful.

Causes

Let’s break down the top 30 causes of a skin condition known as generalized eczema. Eczema, also known as dermatitis, causes red, itchy skin. It can show up all over your body (generalized), or just in certain areas.

1. Genetics: Sometimes, our genes make us more likely to get eczema. If your parents or siblings have eczema, you might get it too.
2. Dry Skin: Skin that’s too dry can crack, itch, and become eczema. It’s important to keep our skin moisturized.
3. Allergens: Things like dust mites, pets, pollens, mold, and dandruff can cause allergic reactions, leading to eczema flare-ups.
4. Irritants: Harsh soaps, detergents, shampoos, and disinfectants can irritate the skin and cause eczema.
5. Climate: Living in a dry or cold climate can dry out your skin, increasing the risk of eczema.

Symptoms

If you’re curious about whether you or a loved one might be experiencing this condition, here are the top symptoms, broken down in simple, everyday language.

1. Dry Skin: The first sign of eczema often includes skin that feels rough and parched. It’s more than just occasional dryness, it’s a persistent dry skin that no amount of lotion seems to fix.
2. Itching: Itching is one of the most common symptoms. The skin might feel so itchy that you’re tempted to scratch until it hurts. It’s especially bad at night, and it could disrupt your sleep.
3. Redness: Eczema causes skin inflammation, making the skin look red or pink. This redness can pop up anywhere on your body, but often appears on the hands, feet, elbows, or knees.
4. Skin Swelling: The affected areas may swell up, especially after scratching. The swelling can be uncomfortable and tender to the touch.
5. Blisters or Sores: In severe cases, eczema can cause blisters or sores to form on your skin. These may ooze fluid and eventually crust over.
6. Changes in Skin Tone: You might notice that parts of your skin are getting darker or lighter than your normal skin tone. This discoloration is a result of the ongoing inflammation.
7. Scaly Skin: The skin may develop a scaly texture, like a reptile’s skin. This rough, flaky skin is another hallmark of eczema.
8. Thickened Skin: Areas affected by eczema might become thicker. This is a result of chronic scratching and rubbing.
9. Sensitive Skin: The skin becomes sensitive and can react to substances that it wouldn’t have before. This can lead to an increase in skin irritation.
10. Skin Cracks: As eczema dries the skin, it may lead to skin cracking, especially on the hands and feet. These cracks can be quite painful.
11. Bumps or Pimples: Some people with eczema develop small bumps or pimples on the affected areas. These bumps might ooze liquid when scratched.
12. Rashes: Eczema can cause a variety of rashes. They can be patchy or cover large areas, and are usually very itchy.
13. Warm Skin: The inflamed areas might feel warm to the touch. This is due to increased blood flow to these areas as your body tries to heal the inflammation.
14. Peeling Skin: As eczema progresses, skin might start to peel off, similar to a peeling sunburn.
15. Bleeding: After excessive scratching, the skin may bleed. This can also lead to potential skin infections.
16. Infections: Open sores or cracks from eczema can become infected. If you see pus, increased redness, or have a fever, you may have an infection.
17. Eye Problems: Eczema around the eyes can lead to redness, swelling, and itching. In severe cases, it could affect vision.
18. Sleep Disturbance: The relentless itching and discomfort from eczema often lead to poor sleep quality.
19. Psychological Distress: Dealing with chronic, uncomfortable skin changes can lead to feelings of embarrassment, frustration, and even depression.
20. Changes in Sweat: Some people with eczema find they sweat more than usual, or their sweat causes their skin to itch.

Diagnosis

Diagnoses and tests for generalized eczema, presented in plain English.

1. Clinical Assessment: The first step is a clinical assessment. The doctor will examine the skin and ask about symptoms and medical history.

2. Patch Testing: This involves applying small patches coated with potential allergens to the skin. If the skin reacts, it might be allergic eczema.

3. Prick Testing: Similar to patch testing, but instead, tiny pricks are made on the skin before applying allergens.

4. Intradermal Testing: Allergens are injected directly under the skin to see if a reaction occurs.

5. Blood Tests: Doctors can look for specific antibodies in the blood that might indicate an allergic response.

6. Biopsy: A small sample of skin is taken and examined under a microscope.

7. Atopy Patch Test: Identifies delayed allergic reactions by applying allergens via patches and observing for 48 hours.

8. Use of a Dermatoscope: This magnifying tool helps doctors examine skin more closely.

9. IgE Level Test: Measures the amount of Immunoglobulin E, an antibody that increases during allergic reactions.

10. RAST Test: Radioallergosorbent test is another type of blood test that detects specific allergens.

11. Food Elimination Diet: If food allergy is suspected, eliminating certain foods might identify the cause.

12. Skin Prick Test (SPT): Small amounts of allergens are pricked into the skin to test for allergies.

13. Total Serum IgE Test: This checks for elevated levels of IgE in the blood, often seen in allergic conditions.

14. Pulsed Dye Laser (PDL) Examination: This test uses a laser to look for changes in blood vessels in the skin.

15. Confocal Microscopy: A non-invasive test providing high-resolution images of the skin to detect eczema.

16. Eosinophil Count: This blood test checks the number of eosinophils, a type of white blood cell often high in allergic conditions.

17. Hydration Test: Measures how well your skin retains moisture, as eczema often causes dry skin.

18. Skin Smear Test: Checks for bacteria or fungi that may be causing or worsening eczema.

19. Sweat Test: Some people’s eczema flares up with sweat, and this test can identify that.

20. Skin Barrier Test: Evaluates how well your skin protects you from environmental irritants.

21. Transepidermal Water Loss Measurement: This test measures the amount of water that evaporates from the skin surface.

22. Lipid Level Test: This test examines the fat levels in your skin, which can affect your skin’s health.

23. pH Test: Checks the skin’s pH, as changes can affect eczema.

24. T-Cell Count: A blood test to measure the number of T-cells, a type of white blood cell, in the body.

25. Skin Scraping: A test where a scalpel is used to scrape off a small skin sample for analysis.

26. Wood’s Lamp Examination: A special lamp is used to illuminate areas of the skin to look for certain conditions.

27. Elemental Diet: This test involves eating a very limited, controlled diet to see if symptoms improve, indicating a food allergy.

28. Elimination-Challenge Diet: Similar to the Elemental Diet, but after elimination phase, foods are gradually reintroduced to identify the culprit.

29. Stool Analysis: Certain digestive issues can manifest as eczema, and stool analysis can help identify these.

30. Magnesium Level Test: Some research suggests a link between low magnesium levels and eczema.

Treatment

Top treatments in a way that everyone can understand. Let’s dive right in:

1. Moisturizers: Applying moisturizers like petroleum jelly, cream, or ointment to your skin right after a bath or shower helps lock in moisture, reducing dryness and itching.
2. Topical Steroids: These are creams or ointments that decrease inflammation and alleviate itching. Remember, it’s best to use them as advised by your doctor to avoid side effects.
3. Oral Antihistamines: These medicines reduce itching and are particularly useful at bedtime because they can make you drowsy.
4. Topical Calcineurin Inhibitors (TCIs): This type of cream reduces inflammation without the side effects associated with long-term use of topical steroids. It’s used for areas like the face or folds of the skin.
5. Topical PDE4 Inhibitors: These are creams like crisaborole (Eucrisa) which can reduce inflammation and help control eczema flare-ups.
6. Phototherapy (Light Therapy): Exposing the skin to controlled amounts of natural or artificial light can reduce eczema symptoms in some people.
7. Systemic Corticosteroids: These are powerful anti-inflammatory drugs used for severe cases. They are generally used for a short time due to potential side effects.
