Thrush is a fungal infection caused by an overgrowth of Candida that affects the mouth, throat, and other parts of the body. The most common symptoms of thrush include white patches in the mouth, a sore throat, difficulty swallowing, pain or burning sensation in the throat, dry mouth, and bad breath. Other symptoms may include redness, cracking, and soreness of the tongue, cracked and crusty lips, or a loss of taste. Treatment for thrush typically includes antifungal medications, which can be taken orally or applied directly to the affected areas. Additionally, maintaining good oral hygiene, avoiding foods and drinks that can worsen thrush, and drinking plenty of fluids can all help reduce symptoms and prevent further infection.
