Step1
Realize that gangrene causes tissue to decay and die (necrosis).
Step2
Understand that gangrene can be caused by a lack of blood supply to a body part.
Step3
Know that gangrene can be caused by bacterial infection, usually Clostridia.

Consider that gangrene can be a complication of bedsores, deep burns, frostbite, a blood clot, infection, severe arteriosclerosis, diabetes, occlusive vascular disease or any condition that compromises adequate circulation to a body part.
Step5
Figure that over the age of 40, gangrene is 50 times more frequent in diabetic men and 70 times more frequent in diabetic women.
