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. It can also occur in the muscles and in organs inside the body, such as the gallbladder.
Treatments for gangrene may include antibiotics, oxygen therapy, and surgery to restore blood flow and remove dead tissue. The earlier gangrene is identified and treated, the better the chances for recovery.
