Acute pancreatitis is an inflammatory injury of the pancreas, including edema, hemorrhage and necrosis, caused by the self-digestion of the pancreatic tissue from a variety of etiologies. Cure usually does not affect life expectancy, but some people with severe symptoms may not be cured or even die. Treatment of mild acute pancreatitis is relatively simple, mainly through fasting, fluid replacement, gastrointestinal decompression, application of antibiotics and other treatments, most patients can be quickly relieved, and the prognosis does not affect life expectancy. In patients with severe acute pancreatitis, localized exudation, bleeding and necrosis of the pancreas are accompanied by systemic multi-organ dysfunction and even shock, and their mortality rate is about 15%. After active resuscitation, patients mostly have complications such as pancreatic pseudocyst, pancreatic abscess, splenic vein embolism, and are left with different degrees of pancreatic insufficiency and other symptoms. While treating patients with acute pancreatitis, they should pay attention to dietary regulation, mainly low-salt and low-fat food, avoid intake of too greasy food, and do not drink alcohol, and do some sports to enhance the immunity of the body, which will help to reduce blood lipids.
