Gangrene is the result of a body part — usually the fingers, toes or legs — losing blood supply or succumbing to an infection. Severe gangrene can result in the loss of a limb. In some cases, gangrene can lead to septic shock, a potentially fatal condition.
Several risk factors can increase the likelihood of gangrene, including:
- Blood vessel diseases (atherosclerosis)
- Chronic kidney disease
- Weakened immune system (HIV or chemotherapy)
- Traumatic injury
If gangrene affects the skin, its symptoms are readily noticeable. Such symptoms include:
- Blue or black discoloration
- Red or bronze discoloration if the area under the skin is affected
- Sores with foul-smelling discharge
- Severe pain followed by numbness
Gangrene becomes particularly dangerous if the bacterial infection within the gangrenous tissue spreads into the body, causing septic shock. Symptoms of septic shock include:
- Fever greater than 100.4º F
- Rapid heart beat
- Low blood pressure
- Shortness of breath
- Persistent or severe pain
The prognosis for gangrene is better if the condition is caught and treated early.
