A yeast infection, also known as candidiasis, is a common fungal infection caused by an overgrowth of Candida, a type of yeast that naturally lives in the body. The infection typically affects the vaginal area in women, but it can also occur in other areas such as the mouth (oral thrush), skin folds, or under the nails. Common symptoms of a vaginal yeast infection include intense itching, burning, swelling, redness, and a thick, white discharge that resembles cottage cheese. Some women may also experience pain during urination or intercourse.

Yeast infections can be triggered by various factors such as antibiotics, hormonal changes (pregnancy, birth control, menopause), a weakened immune system, diabetes, or wearing tight or non-breathable clothing that creates a warm, moist environment.

Treatment for yeast infections typically involves antifungal medications, available in the form of creams, suppositories, or oral pills. Over-the-counter treatments are common, but persistent or recurring infections may require prescription medication. Maintaining proper hygiene, wearing breathable fabrics, and managing underlying conditions can help prevent future infections.
