What Is Gangrene? What Causes Gangrene?
Gangrene occurs when tissue dies (necrosis) because its blood supply is interrupted. Gangrene may be caused by an infection, injury, or a complication of a long-term condition that restricts blood circulation. It most commonly occurs in the extremities - the toes, fingers, arms and legs - but internal organs and muscles may also become gangrenous. There are five main types of gangrene: 1. Dry gangrene. 2. Wet gangrene. 3. Gas gangrene. 4. Internal gangrene. 5. Fournier's gangrene.
