A yeast infection, also known as candidiasis, is a common fungal infection that occurs when there is an overgrowth of the Candida yeast, typically Candida albicans, in the body.
It can affect various parts of the body, but vaginal yeast infections are most common in women.
Symptoms often include itching, burning, redness, and abnormal discharge. Yeast infections can also occur in the mouth (oral thrush) or in the skin folds.
Treatment typically involves antifungal medications, either topical or oral, to reduce the yeast overgrowth and alleviate symptoms.
