What is atopic dermatitis?
Atopic dermatitis (eczema) is driven by a combination of a weakened skin barrier and an overactive immune response. The skin loses moisture easily and lets irritants and allergens in more readily, triggering itch-scratch cycles that keep flares going.
Common symptoms
- Dry, rough, itchy patches — often cheeks and scalp in infants, elbow/knee creases in older children
- Red or darkened, thickened skin with repeated scratching
- Weeping or crusting during flares, especially if infected
- Sleep disturbance from night-time itching
What can trigger flares
Flares can be worsened by dry weather, sweating, harsh soaps, wool clothing, and in some children, specific allergens such as house dust mite or certain foods. Not every child's eczema is food-triggered — this needs proper testing rather than broad, unsupervised diet elimination.
Diagnosis
Diagnosis is largely clinical, based on the pattern and history of the rash. Where food or inhalant triggers are suspected, skin prick testing helps separate true triggers from coincidental ones, since self-reported food triggers are frequently inaccurate.
Treatment approach
- Daily moisturising (emollients) — the single most important routine, even between flares
- Gentle, soap-free cleansers and lukewarm baths
- Topical corticosteroids or non-steroidal anti-inflammatory creams for active flares, used correctly and for the right duration
- Identifying and reducing specific confirmed triggers
- Treating any coexisting food allergy, asthma or rhinitis as part of the same allergic picture
Talk to Dr. Narwani: If your child's symptoms are affecting sleep, school, play or growth, or you suspect a specific trigger, book a consultation for proper allergy work-up rather than guessing at home remedies.
