Intertrigo is a skin condition that occurs within the skin folds of the body and is caused by chafing of the skin. It is more common in overweight individuals and may occur on the thighs, breasts or the underside of the belly. Symptoms of the rash that develops under the rolls of belly fat include redness, itchiness and discomfort. The American Osteopathic College of Dermatology recommends that a doctor look at the rash in case an underlying medical condition, such as psoriasis, is causing it.
Clean the Skin
One of the risks of intertrigo is that an infection may develop if cuts and breaks occur. To prevent infection, keep the skin clean at all times, recommends the Skinsight website. Do not use any harsh soap to wash the area; instead rely on a gentle cleanser.
Moist Compresses
You may use moist compresses to ease an intertrigo rash that occurs on the underside of the belly, according to the American Osteopathic College of Dermatology. The moist compresses may control the oozing that can develop from the skin irritation. Place the compress on the rash and leave it on for several minutes. Burrow’s solution is a common household antiseptic that you can place on the compresses. Once you remove the compress, air dry the area or use a hair dryer on the cool setting.
Cotton Fabric
Pieces of cotton fabric help absorb perspiration and can prevent chafing between the folds of the skin. Wrap a band of cotton fabric around the area of your belly where the skin folds meet. Change the fabric as needed if the pieces become moistened with sweat.
Powder
Keep a small amount of absorbent powder on hand if you notice any sweating that occurs in the area of the rash. Apply a generous amount to the belly area to soak up sweat.
