Candidiasis is a fungal infection caused by an overgrowth of the Candida yeast, which normally lives in small amounts in our bodies. This condition can affect various parts of the body, including the mouth, throat, and genital area. Symptoms may include itching, redness, and discomfort, depending on the location of the infection. The most common type of candidiasis is oral thrush, which appears as white patches in the mouth. Another common form is vaginal yeast infection, leading to irritation and discharge. Treatment often involves antifungal medications, and maintaining a balanced diet can help prevent future infections.
