Patients with acute pancreatitis who have been fasting for a long time need to resume their diet regularly, step by step, and in a stepwise manner when their condition stabilizes and resumes a transoral diet. The doctor should conduct a comprehensive assessment of the disease (removal of the cause, time of onset, progress of the disease, presence of infection around the pancreas, presence or absence of encapsulation of fluid, presence or absence of gastrointestinal fistula, etc.), and after passing the assessment, first drink water through the mouth, and after no discomfort, gradually transition to a light liquid diet, semi-liquid diet, until the resumption of normal diet. During the resumption of diet, enteral nutrition by nasal intestinal tube or oral nutritional powder should be used to ensure nutrition supply, and blood test indexes should be reviewed regularly. If abdominal pain, vomiting or bloating occurs after eating, please stop eating and contact the doctor. The recommended steps to resume eating are as follows: Step 1: plain water, fruit juice; Step 2: rice soup, vegetable soup, egg flower soup, rice porridge, vegetarian noodles; Step 3: vegetarian wontons, bread, less oil cookies, crushed soft vegetables, fruits, etc., gradually add lean meat, steamed fish, shrimp and other high-protein foods; Step 4: gradually release to a normal diet, usually 2-6 months after discharge from the hospital for seriously ill patients. It is recommended not to drink meat soup during this period, which is not nutritious and may lead to the re-emergence of pancreatitis in many patients. To prevent recurrence, fat-rich foods need to be avoided for a considerable period of time after discharge from the hospital. After recovering from the disease, it is still necessary to pay attention to the structure of the diet, avoid smoking, alcohol, greasy food and overeating.
