L22: Diaper [napkin] dermatitis

Your skin is inflamed in the diaper area.

Certain substances from your urine and stool are damaging your skin. As a result, your skin has become inflamed in the diaper area. Your skin is red. Blisters may also form, and the skin may become scaly. The affected areas often weep. As a result, those areas are more susceptible to germs and can become even more inflamed.

Diarrhea or a weakened immune system favor skin inflammation.
