Gangrene

What Is Gangrene?

Gangrene happens when tissues in your body die after a loss of blood caused by illness, diseases, or infection. It usually happens in extremities like fingers, toes, and limbs, but you can also get gangrene in your organs and muscles. There are different types of gangrene, and all of them need medical care right away.

Signs and symptoms

Symptoms may include a change in skin color to red or black, numbness, pain, skin breakdown, and coolness. The feet and hands are most commonly involved.

Causes

Gangrene is caused by a critically insufficient blood supply (e.g., peripheral vascular disease) or infection. It is associated with diabetes and long-term tobacco smoking.
