Intertrigo Under the Stomach: What to Know

A fold beneath the stomach can stay warm and damp after bathing, sweating or exercise. Repeated contact and movement irritate the outer skin, causing redness, soreness, itching, burning, scaling or shallow cracks. Yeast may take advantage of the moisture and create a more persistent rash; [Skin Yeast Infection](/conditions/cutaneous-candidiasis/) is one condition a clinician may consider. Learn about the wider pattern on the [Intertrigo](/conditions/intertrigo/) page.

Use a gentle cleanser and lukewarm water, rinse well, and pat the fold dry. Drying after every shower and after sweating matters more than vigorous rubbing. Choose loose, breathable clothing and change damp garments promptly. A clean, dry fabric layer may limit rubbing; remove it when moist. Avoid perfume, harsh scrubs and unprescribed combination creams on broken skin. When yeast is diagnosed, [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) may be part of care. Recurrent heavy sweating can be discussed with a clinician, including whether [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) is appropriate.

See a clinician if the area remains inflamed despite careful drying, returns frequently or limits movement. Prompt assessment is needed for pus, fever, rapidly expanding redness, marked warmth, swelling, red streaks or worsening pain. People with diabetes or reduced immunity should seek advice early for a new fold rash. A professional examination can separate intertrigo from eczema, allergy or another infection.

Does the appearance suggest yeast, bacteria or friction? What can I safely use on a crack or open area? How should I dry and protect the fold at work or during exercise? When should I be rechecked?
