Intertrigo Under the Belly: Treatment Options

The lower abdominal fold can trap sweat and heat while movement creates repeated rubbing. The resulting inflammation may cause a red, tender, itchy or burning patch, sometimes with scaling, cracks or an unpleasant smell. Yeast can grow in persistently damp skin and may produce small surrounding spots; [Skin Yeast Infection](/conditions/cutaneous-candidiasis/) is one possible related problem. Read more about the condition itself at [Intertrigo](/conditions/intertrigo/).

Rinse or wash the area gently, then dry every part of the fold by patting rather than rubbing. Let air reach the skin when practical and wear loose, breathable clothing. A clean cotton or moisture-wicking layer may separate surfaces, but remove it when damp. Do not use perfume, harsh antiseptic, home acids or steroid cream unless a clinician recommends it. If yeast is suspected, a clinician may recommend [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/). For sweating that repeatedly keeps the fold wet, ask whether [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) is suitable; it should not be placed on broken or severely irritated skin without instructions.

Book an assessment when the rash persists, returns often, interferes with walking or becomes cracked, weeping or increasingly sore. Seek prompt care for fever, pus, rapidly spreading redness, marked warmth, swelling, red streaks or a strong new odour. Diabetes, immune suppression or a history of difficult skin infections lowers the threshold for medical advice because a fold infection may need a different approach.

What is driving this rash: friction, yeast, bacteria or another skin condition? Which product should touch the area, and for how long? How can I keep the fold dry during exercise or hot weather? What changes mean I should return?
