Overview

Gangrene is death of body tissue due to a lack of blood flow or a serious bacterial infection. Gangrene commonly affects the arms and legs, including the toes and fingers, but it can also occur in the muscles and in organs inside the body, such as the gallbladder.

Your risk of gangrene is higher if you have an underlying condition that can damage your blood vessels and affect blood flow, such as diabetes or hardened arteries (atherosclerosis).

Treatments for gangrene include surgery to restore blood flow and remove dead tissue, antibiotics if there is an infection, and hyperbaric oxygen therapy. The earlier gangrene is identified and treated, the better your chances for recovery.
