Overview of human body necrosis


Necrosis during the death of body tissues. Necrosis can be cured by removing dead tissue, but the affected tissue cannot be restored to good condition .

Types of necrosis

One of the most common types of necrosis is the result of frostbite . During freezing, the tissues are severely damaged by the cold, and if the condition is not treated quickly, the frozen areas turn black and die. These black areas are necrotic or necrotic and cannot be cured and are usually removed during surgery.

Another type of necrosis occurs when a clot, such as deep vein thrombosis (DVT), forms in a blood vessel and blocks blood flow to a specific area of the body. If blood flow is not quickly restored, the area becomes oxygen deficient and eventually dies. This usually occurs in the legs (but can occur anywhere on the body) and can lead to tissue loss below the blockage if the blood vessel is completely blocked.

Causes and risk factors

Necrosis is caused by a lack of blood and oxygen in the tissues. It can be caused by chemicals, a cold, trauma, radiation , or chronic conditions that interfere with blood flow. There are many types of necrosis, as it can affect many areas of the body, including bones, skin, organs, and other tissues.

A clot or cold doesn't always lead to necrosis, these are just common examples. Many types of lesions can lead to necrosis. The infection can destroy surrounding tissues until they become necrotic, as can injuries such as a car accident or falling down stairs. Any time blood flow to an area is blocked or the area is so damaged that blood cannot flow to and from it, necrosis is possible.

Watch out

The good (and bad) news is that a complete blockage of blood flow is usually painful and painful enough for a person to seek treatment immediately. Treatment may include surgery to restore blood flow or remove damaged tissue, use antibiotics to prevent or treat an infection, or treat a burn or other problem that caused the original damage .
