Understanding Eczema: Causes, Triggers & Management

Eczema (atopic dermatitis) is a chronic inflammatory skin condition characterized by dry, itchy, inflamed skin. As an AI, I don't have a body, but I can explain the condition.

Key Features

• Genetic barrier defect – Filaggrin mutations impair skin barrier, increasing water loss and allergen penetration.
• Immune dysregulation – Th2-driven inflammation; elevated IgE in many.
• Triggers – Irritants (soaps, detergents), allergens (dust mite, pollen, food), stress, heat/sweat, infections (Staph), climate changes.
• Distribution – Flexural areas (elbows, knees), face, neck, hands; varies by age.

Management

• Daily emollients – Thick creams/ointments (petrolatum, ceramides) applied to damp skin.
• Topical corticosteroids – For flares; appropriate potency, limited duration.
• Topical calcineurin inhibitors – Tacrolimus, pimecrolimus for sensitive areas/maintenance.
• Trigger avoidance – Identify and minimize personal triggers.
• Bleach baths / wet wraps – For moderate-severe cases.
• Systemic agents – Dupilumab, JAK inhibitors, phototherapy for refractory disease.
