Gastrointestinal Fistula


A gastrointestinal (GI) fistula is an abnormal opening in your stomach or intestines. Fluids from your stomach and intestines leak into other parts of your body through the opening. They can leak into other organs or through your skin to the outside of your body. A GI fistula can lead to infections, malnutrition (not enough calories or nutrients), or dehydration.
