(Dry Gangrene; Gas Gangrene; Organ or Tissue Death; Wet Gangrene)
Gangrene is the death of an organ or body tissue. When the blood supply is cut off, the tissue doesn't get enough oxygen and begins to die. If the gangrene is widespread, shock
There are three main types:
- Dry gangrene—lack of blood supply causes the tissue to dry up and slough off
- Wet gangrene—usually occurs when the tissue is infected with bacteria, tissue becomes moist and breaks down
- Gas gangrene—a particular type of bacteria ( Clostridia ) produces gas bubbles in the tissue
Causes of gangrene include:
- Infection, especially after surgery or injury
These factors increase your chance of developing gangrene. Tell your doctor if you have any of these:
Symptoms may include:
- Pain, followed by numbness when the tissue is dead
- Sloughing off of skin
- Color changes, ranging from white, to red, to black
- Shiny appearance to skin
- Frothy, clear, watery discharge
- Fever and chills
- Nausea and vomiting

The doctor will ask about your symptoms and medical history, and perform a physical exam.
Tests may include:
- Blood tests
- Tests of the discharge and the tissue
- X-rays —a test that uses radiation to take pictures of structures inside the body
CT scan—a type of x-ray that uses a computer to make pictures of the inside of the body MRI scan—a test that uses magnetic waves to make pictures of the inside of the body
