The clinical manifestations of acute pancreatitis vary in severity, and the symptoms of light pancreatitis are relatively mild, while heavy pancreatitis is often acute, with severe symptoms, and if not rescued in time, can lead to death due to shock and various serious complications. The main manifestations are severe pain in the upper and middle abdomen, which can be accompanied by paroxysmal intensification, and when complicated by peritonitis, the pain can diffuse throughout the abdomen, and there can be obvious pressure pain and rebound pain. Next, the patient has nausea, vomiting, abdominal distension, fever and other symptoms. Once diagnosed with acute pancreatitis, 90% of patients can be relieved clinically through fasting, fluid reduction and anti-inflammatory, nutritional support and other conventional treatments, 10% of patients may evolve into heavy pancreatitis, heavy pancreatitis requires the application of drugs that inhibit pancreatic secretion and inhibit pancreatic enzyme activity, and surgery is required if medical treatment is not effective. The key to the prevention of acute pancreatitis is a reasonable diet, avoid excessive alcohol consumption, especially do not drink and overeat. In particular, patients with biliary tract diseases should pay more attention to a light diet and strictly abstain from alcohol. For people who have chronic pancreatitis, they should eat less and eat more.
