Overview

Anal Fistula

Anal Fistula is an abnormal tunnel between the anal canal and skin near the anus.

Asthma

Asthma is a chronic inflammatory disease of the airways that causes episodes of wheezing, coughing, chest tightness, and shortness of breath. The airways become inflamed and overly sensitive to triggers such as allergens, pollution, exercise, or respiratory infections. Symptoms may vary from mild to severe and can sometimes become life-threatening if not properly managed. With appropriate treatment and trigger avoidance, most people with asthma can lead normal and active lives.
