Eczema: Causes, Symptoms, Types, Treatment & Prevention 

~Introduction

Eczema is a common inflammatory skin condition that causes dryness, itching, redness, and irritation. It can affect people of all ages, from infants to adults, and often follows a chronic or recurring pattern.

Eczema is not contagious, but it can significantly impact quality of life due to persistent itching and visible skin changes. With proper understanding and management, symptoms can be effectively controlled.

~What is Eczema?

Eczema, also known as dermatitis, refers to a group of skin conditions that cause inflammation. The skin becomes sensitive, dry, and prone to irritation.

It typically involves a weakened skin barrier, making it easier for irritants, allergens, and microbes to penetrate the skin.

~Common Symptoms of Eczema

Symptoms vary depending on the type and severity but generally include:

Primary Symptoms

• Dry, sensitive skin

• Intense itching (pruritus)

• Red or inflamed patches

• Rough, scaly, or thickened skin

Advanced Symptoms

• Cracked or oozing skin

• Crusting or swelling

• Darkened patches (hyperpigmentation)

• Small bumps or blisters

~Major Types of Eczema

Eczema is not a single disease—it includes several types.

1. Atopic Dermatitis

Atopic Dermatitis is the most common form.

• Often begins in childhood

• Linked to allergies and asthma

• Affects face, neck, elbows, and knees

2. Contact Dermatitis

Contact Dermatitis occurs when the skin reacts to substances.

• Caused by soaps, perfumes, chemicals

• Symptoms appear at the point of contact

3. Dyshidrotic Eczema

Dyshidrotic Eczema causes small itchy blisters.

• Affects hands and feet

• Often triggered by stress or sweating

4. Nummular Eczema

• Coin-shaped patches

• Often mistaken for fungal infections

5. Seborrheic Dermatitis

Seborrheic Dermatitis mainly affects oily areas.

• Common on scalp, face, and chest

• Causes dandruff and flaking

6. Stasis Dermatitis

• Occurs due to poor blood circulation

• Usually affects the lower legs

~Causes of Eczema

The exact cause is complex and involves a combination of genetic and environmental factors.

1. Genetic Factors

A family history of eczema, asthma, or allergies increases risk.

2. Immune System Dysfunction

An overactive immune response leads to inflammation.

3. Skin Barrier Defects

The skin loses moisture easily and becomes vulnerable.

4. Environmental Triggers

• Dust, pollen, and pollution

• Harsh soaps and detergents

• Weather changes (cold/dry air)

5. Stress

Emotional stress can trigger or worsen flare-ups.

~Risk Factors
