Causes of Gangrene

There are several factors that may cause gangrene to occur on your body. Some of these include:

• a crush injury(something heavy falls on you and stops blood flow to a part of the body).
• a severe burn
• frostbite.
• any disease that affects blood circulation(arteriosclerosis, diabetes, smoking, or Raynaud's disease).
• infection of wounds.

Now that you know the causes, you must know the symptoms. There are totally different symptoms for the two different types of gangrene you can get:
