Gangrene: Symptoms & Signs

Medically Reviewed on 3/27/2021

Gangrene refers to dead or dying tissue in the body that develops due to inadequate blood circulation. There are two major types of gangrene, known as wet gangrene and dry gangrene.

Signs and symptoms of gangrene can include

  • skin blisters,
  • blue skin from poor circulation,
  • dark scabs,
  • skin discoloration, or
  • skin ulcers.

Other symptoms can be dependent on the exact cause or the presence of the infection with wet gangrene. These can include fever or low blood pressure, creaky joints, pus or foul-smelling discharge, as well as other symptoms of infection.

Causes of gangrene
