Gangrene refers to the decay and death of tissue resulting from an interruption in blood flow to a certain area of your body. Some types of gangrene also involve a bacterial infection. Gangrene most commonly affects the extremities, including your toes, fingers and limbs, but can also occur in your muscles and internal organs.

Your chances of developing gangrene are higher if you have an underlying condition that can damage your blood vessels and impede blood flow, such as diabetes or atherosclerosis.

Treatments for gangrene include surgery to remove dead tissue, antibiotics and other approaches. The prognosis for recovery is good if gangrene is identified early and treated quickly.
