Eczema

Eczema is one of the most widespread skin conditions affecting millions worldwide. Characterized by inflammation, redness, dryness, and intense itching, it can significantly impact daily life. It is not a single disease but rather a group of conditions that cause the skin to become irritated and inflamed.

This blog explores everything you need to know about eczema—its causes, symptoms, types, diagnosis, treatment options, and prevention strategies.

What is Eczema?

Eczema, also known as dermatitis, refers to a group of chronic skin disorders marked by itchy, inflamed, and irritated skin. It can affect people of all ages, though it is most common in children. Some people may outgrow eczema, while others continue to experience flare-ups throughout their lives.

While it is not contagious, it can be uncomfortable and distressing. The severity ranges from mild dryness and itching to painful rashes and blisters that may ooze or become infected.

What Causes Eczema?

The exact cause remains unknown, but it is believed to result from a combination of genetic, immune system, and environmental factors.

Key Causes and Triggers:

1. Genetics – A family history of eczema, asthma, or hay fever increases the risk.

2. Overactive Immune System – The immune system reacts strongly to irritants, leading to inflammation.

3. Environmental Factors – Pollution, harsh weather, and allergens can trigger flare-ups.

4. Skin Barrier Dysfunction – A weak skin barrier loses moisture easily, making it prone to irritants and infections.

5. Stress and Hormonal Changes – Stress and hormonal fluctuations can worsen eczema.

6. Allergens – Dust mites, pet dander, pollen, and mold are common triggers.

7. Chemical Irritants – Soaps, detergents, shampoos, disinfectants, and perfumes can irritate sensitive skin.

Common Symptoms of Eczema

The signs and symptoms vary depending on the type and severity but usually include:

• Dry, scaly skin

• Redness and inflammation

• Intense itching (worsens at night)

• Cracked, thickened skin

• Small raised bumps that may ooze fluid

• Skin infections due to excessive scratching

Eczema flare-ups can appear on different body parts, including the face, hands, elbows, knees, and feet.

Types of Eczema

There are several types of eczema, each with unique triggers and symptoms:

1. Atopic Dermatitis

Complications of Eczema

If left untreated, eczema can lead to several complications:

• Skin infections (bacterial, viral, or fungal) due to scratching

• Sleep disturbances caused by severe itching

• Thickened and leathery skin from chronic scratching (lichenification)

• Emotional stress and anxiety, leading to decreased quality of life

Diagnosis of Eczema

Dermatologists diagnose eczema based on:

1. Medical history – Family history of allergies, asthma, or hay fever.

2. Physical examination – Inspecting skin patches and rash patterns.

3. Patch testing – To identify allergens in contact dermatitis.

4. Skin biopsy – Rarely needed, but may help rule out other conditions.

Treatment Options for Eczema

There is no permanent cure for eczema, but treatments can effectively manage symptoms and reduce flare-ups.

1. Medications

• Topical corticosteroids – Reduce inflammation and itching.

• Calcineurin inhibitors (tacrolimus, pimecrolimus) – Control immune response.

• Antihistamines – Help relieve itching.

• Antibiotics/antivirals – If skin infections occur.

• Immunosuppressants & Biologics – For severe cases (e.g., Dupilumab).

2. Moisturizers

• Frequent use of fragrance-free, hypoallergenic moisturizers prevents dryness.

3. Phototherapy

• Controlled exposure to ultraviolet (UV) light reduces inflammation.

4. Lifestyle and Home Remedies

• Apply moisturizers daily.

• Avoid scratching; keep nails trimmed.
