1. Candidiasis

Candidiasis is a fungal infection caused by the overgrowth of a yeast called Candida, which normally lives in small amounts in the body. It can affect various areas, such as the mouth (thrush), skin, or genital region (yeast infection). Factors like a weakened immune system, antibiotics, or diabetes can promote this overgrowth. Symptoms may include itching, discomfort, and unusual discharge. Treatment usually involves antifungal medications. While candidiasis is common and often easily treated, it can become a problem if it recurs frequently or occurs in severe forms.
