Skin gangrene involves the death of tissue usually due to a decrease in blood supply to the affected area followed by a bacterial invasion. Gangrene is the result of a bacterial infection. Serious lesions (for instance, a crushed leg) may block the access of blood and oxygen to the damaged area and create conditions for the development of bacteria. Infection progresses within hours or days of the lesion. Gangrene may also develop as the result of a surgical wound, particularly when the amount of blood that reaches the affected area is limited. This is particularly dangerous for people with poor circulation.

In conclusion, we may say that gangrene develops when a tissue dies due to lack of blood irrigation and becomes exposed to complications of infectious nature. Self-esteem and self-respect are associated with blood. In this case, blood ceases to irrigate the area of the lesion. What is at stake here is one’s capacity to understand what is good for him and his ability to be who he really is without need for approval from others. It is often necessary to amputate the area affected by gangrene.

It is useful to consider what part of the body was affected and how. If amputation is necessary, see Amputation.
