Eczema (Atopic Dermatitis): Causes, Symptoms & Treatment Guide

Overview

Eczema, medically known as atopic dermatitis, is a chronic inflammatory skin condition characterized by dry, itchy, and inflamed skin. It often begins in childhood but can persist into adulthood. In India, eczema affects millions, with triggers varying from climate to diet. It is not contagious but can significantly impact quality of life.

Causes

Genetic Factors

A family history of eczema, asthma, or hay fever increases risk. Mutations in the filaggrin gene compromise the skin barrier.

Immune System Dysfunction

An overactive immune response to irritants or allergens leads to inflammation.

Environmental Triggers

• Dry or humid weather
• Pollution and dust mites
• Harsh soaps and detergents
• Stress and sweat
• Certain foods (eggs, dairy, nuts)

Symptoms

• Intense itching, especially at night
• Red to brownish-gray patches, often on hands, feet, ankles, wrists, neck, upper chest, eyelids, and inside the bends of elbows and knees
• Small, raised bumps that may leak fluid and crust over when scratched
• Thickened, cracked, scaly skin
• Raw, sensitive skin from scratching

Diagnosis

Diagnosis is primarily clinical, based on medical history and physical examination. A dermatologist may perform a patch test to identify allergens or a skin biopsy to rule out other conditions.

Treatment Options

Medical Treatments

• Topical corticosteroids (e.g., hydrocortisone) to reduce inflammation
• Topical calcineurin inhibitors (e.g., tacrolimus) for sensitive areas
• Antihistamines (e.g., cetirizine) for itching
• Moisturizers and emollients to repair skin barrier
• In severe cases, oral immunosuppressants (e.g., cyclosporine) or biologics (e.g., dupilumab)

Lifestyle Management

• Regular moisturizing
• Avoiding triggers
• Wearing soft, breathable fabrics
• Using mild, fragrance-free products

Prevention

• Keep skin well-moisturized
• Use gentle cleansers
• Manage stress through yoga or meditation
• Maintain a cool, humid environment
• Avoid known allergens

Ayurvedic Perspective & Remedies

In Ayurveda, eczema is linked to imbalance of Pitta and Kapha doshas, leading to toxin accumulation (Ama). Remedies include:

• Neem (Azadirachta indica): anti-inflammatory and antimicrobial
• Turmeric (Curcuma longa): reduces inflammation
• Aloe vera gel: soothes and moisturizes
• Manjistha (Rubia cordifolia): blood purifier
• Diet: avoid spicy, oily, and fermented foods; include bitter vegetables and ghee

Always consult an Ayurvedic practitioner before starting any remedy.
