Overview What is necrosis? Necrosis is the death of the cells in your body tissues. Necrosis can occur due to injuries, infections or diseases. Lack of blood flow to your tissues and extreme environmental conditions can also cause necrosis. While dead body tissue can be removed, it can’t be brought back to good health. What are the different patterns of necrosis? When your body’s cells die of necrosis, they form different patterns and appearances. The dead cells appear one of six ways. These patterns include: Coagulative necrosis With coagulative necrosis, the dead cells remain firm and look normal for days after death. Lack of blood flow or oxygen to any part of your body except your brain can cause coagulative necrosis. Liquefactive necrosis With liquefactive necrosis, the dead cells partially or completely dissolve within hours of death. Then they transform into a thick, sticky liquid. The cells sometimes appear creamy yellow because pus is forming. Infections and lack of oxygen to your Fat necrosis With fat necrosis, damaged cells release Caseous necrosis With Fibrinoid necrosis With Gangrenous necrosis With gangrenous necrosis, your skin appears black and is beginning to rot. Lack of blood flow to your legs can cause gangrenous necrosis. It can sometimes affect your arms and fingers too. What are the different types of necrosis?

Colon and small intestine The small intestine and colon are parts of your digestive tract, which processes the foods you eat. The intestines take nutrients from the foods. What isn't absorbed by the intestines continues along the digestive tract and is passed as stool during a bowel movement. Intestinal ischemia (is-KEE-me-uh) describes a variety of conditions that occur when blood flow to your intestines decreases. Ischemia can be due to a fully or partially blocked blood vessel, usually an artery, or low blood pressure leading to an overall reduced blood flow. Intestinal ischemia can affect your small intestine, your large intestine (colon) or both. The decreased blood flow doesn't provide enough oxygen for the cells in your digestive system. Intestinal ischemia is a serious condition that can cause pain and make it difficult for your intestines to work properly. In severe cases, loss of blood flow to the intestines can damage intestinal tissue and possibly lead to death. Treatments are available for intestinal ischemia. To improve the chances of recovery, it's crucial to recognize the early symptoms and get medical help right away. Symptoms Signs and symptoms of intestinal ischemia can develop suddenly (acute) or gradually (chronic). Signs and symptoms may be different from one person to the next, but there are some generally recognized patterns that suggest intestinal ischemia. Symptoms of sudden (acute) intestinal ischemia Signs and symptoms of acute intestinal ischem...
