What are the different types of gangrene?

When the blood supply to the part of the body part is stopped, the resulting tissue death is called gangrene. There are two main categories of gangrene: dry and wet. The dry type is the result of cardiovascular diseases of the cutting of circulation, while the wet variety is caused by bacterial infection, often due to damage. Both varieties usually affect the limbs and require the removal of dead tissue as a primary medical treatment. Less common subtypes of the disease can destroy parts of the trunk, face or groin, often after a serious trauma or rare health. Tissue death - called necrosis - begins if the circulation stops for a sufficiently long time and if enough cells are denied oxygen. Infections, cardiovascular disease and traumatic damage can initiate processes that lead to necrosis. While each part of the body can become gangrenous, most often afflico limbs, especially hands, legs and numbers. Different varieties of this disease are clinically classified according to their symptoms and diseases orInjuries that began the necrotic process.

One common type of necrosis is dry gangrene. This is often the result of an arterial blockade due to cardiovascular disease and may occur as a complication of diabetes. It is a slow and progressive disease that is not caused by trauma and usually does not lead to bacterial infection. Tissues first become red or brownish black and cold, then dry and may fall from the body. If the underlying diseases are not treated, dry gangrene can affect more than one part of the body in a susceptible individual.

wet gangrene is caused by wound infection, where an uncontrolled bacterial cell increases blood flow to the affected area. The muscles are attacked by bacterial cells and putrefs, while immune cells are unable to achieve the site of infection and kill bacteria. In gas gangrene bacteria of clostridia multiply in tissue with oxygen and release the amount of gasas a by -product of their metabolism. Since Clostridia thrives in the absence of oxygen, they increase how tissue dies.

The rare type of necrosis that destroys the tissue of the face is called noma, while necrotizing fasciitis is a more common type of infection in which bacteria destroys tissues. Dry and wet gangrenes attack all tissues in the body area below the point of blood blocking, but especially destroy the skeletal muscle. None of the gangrene types can be treated with antibiotics because these chemicals cannot achieve infected tissues without circulating blood. Surgical removal of dead tissue is necessary, and in some cases this involves amputation of gangrenous limb if necrosis spreads far enough.
