What is gangrene disease and how is it treated?

Defined below: Gangrene means death of tissue somewhere in your body. That alone can cause problems with loss of function, but when the dead tissue becomes infected, this can become life threatening (e.g. Gas gangrene). The treatment and prognosis depends on the location, amount of tissue and whether there is infection. Dead tissue may need to be removed, if infection occurs, antibiotics may be necessary.
