A fistula is an abnormal connection between two body parts, often involving organs or blood vessels. It can occur due to injury, surgery, infection, or inflammation. Fistulas can develop in various areas, such as the digestive system, urinary tract, or between blood vessels. Symptoms of a fistula may include pain, swelling, or discharge from the affected area. Treatment often involves surgery to close the fistula and address any underlying issues. Proper medical care is essential to prevent complications and promote healing. Regular follow-ups with a healthcare provider are important for managing this condition effectively.
