Intertrigo is a type of inflammation of the skin, a type of eczema. The skin may be red or red-brown and it may be moist, have coatings, flaking or small cracks/sores in the skin. It can cause itching or discomfort.
Intertrigo comes in skin folds, so that heat and humidity/sweat play a role. One imagines that the skin becomes irritated and this creates an inflammation, and eczema appears in the skin. In addition, the skin barrier is weakened and the growth of bacteria and fungi increases. Age, nutrition and other diseases can predispose.
One should try to reduce moisture and sweating in the area, and at the same time strengthen the skin barrier with a moisturizer. Antifungals and cortisone creams are common medical treatment.
