If left untreated, gangrene can cause severe health problems, including organ failure, sepsis, and even death.

Types of gangrene:

There are mainly 5 types of gangrene, and each shows different symptoms. These are:

1. Wet gangrene:

Bacterial infections of the affected tissue cause wet gangrene, which progresses rapidly. In addition to discoloration of the skin, wet gangrene also causes blistering, oozing, and a bad odor from decomposing tissues. These infected tissues become the main cause of wet gangrene. When a body part gets injured, then the cells get to die. This is very dangerous as it spreads quickly to the whole body. Especially since it becomes more dangerous to those who already have diabetes.

2. Dry gangrene:

Dry gangrene usually results from poor blood circulation in the affected area. This dry gangrene tends to progress more slowly than wet gangrene.
