In cases of acute pancreatitis with severe nausea, it's crucial to first decompress the stomach and intestines. By removing gases, stomach contents, and gastric fluids, this effectively reduces symptoms such as abdominal distension, nausea, and vomiting. It also helps alleviate the burden on the intestines, indirectly relieving symptoms of nausea and vomiting. For more severe cases, it may be necessary to administer antiemetic drugs, including medications like Gastropin, which effectively alleviate issues caused by inflammation-induced nausea and vomiting. When necessary, drugs that suppress pancreatic enzyme secretion should also be administered, as these can help improve symptoms of nausea in acute pancreatitis.

What are the clinical manifestations of acute pancreatitis?

Acute pancreatitis includes two main types: acute edematous pancreatitis and acute necrotizing pancreatitis. It is a common acute and critical condition of the digestive system, particularly acute necrotizing pancreatitis, which can often be life-threatening. The primary symptoms usually include severe upper left abdominal pain, fever, chills, shivering, vomiting, etc. There is a significant relationship between abdominal pain and eating; generally, the pain worsens after eating and can sometimes radiate to the back. The main causes could be binge drinking, overeating, cholecystitis, gallstones, or hyperlipidemia, among others. Diagnosis is usually confirmed through examinations such as an upper abdominal CT and serum and urine amylase tests, followed by appropriate treatment measures.

How long after being discharged with acute pancreatitis can one resume a normal diet?

After being discharged from the hospital, patients with acute pancreatitis, upon re-examination of routine blood tests and upper abdominal CT scans showing complete healing of pancreatitis, may, as appropriate, consume a low-fat, high-carbohydrate diet and gradually transition back to a normal diet. This process generally requires at least two months to be considered safe. Patients discharged after acute pancreatitis must abstain strictly from alcohol, avoid binge eating, and avoid overly greasy food. Greasy food can easily lead to increased bile discharge and potentially cause blockage of the pancreas, possibly triggering a recurrence of pancreatitis.

What can be eaten during the recovery period of acute pancreatitis?

Patients with acute pancreatitis in the recovery phase should start to eat some sugary liquid diets, beginning with easily digestible sugary foods. Generally, it is recommended to transition from liquid to semi-liquid diets, and then to a normal regular diet. However, patients with acute pancreatitis in the recovery phase should still avoid overeating and consuming too greasy foods. They should also abstain from alcohol and avoid eating overly fatty foods such as meat fried noodles, fried rice with eggs, and braised pork. These foods should be largely avoided, while increasing the intake of protein-rich foods for the patient.

Dietary care for acute pancreatitis

Symptoms of acute pancreatitis include severe upper abdominal pain. During the treatment, it is essential to fast and decompress the stomach and intestines initially during the abdominal pain period. Once the pain subsides, the patient can begin a liquid diet, followed by a gradual transition to a semi-liquid diet under the guidance of a doctor. Since the causes of acute pancreatitis include binge eating or excessive alcohol consumption, patients with acute pancreatitis should abstain from alcohol and maintain a balanced diet to prevent binge eating. A light diet is preferable, avoiding fatty, greasy, fried, and barbecued foods. Additionally, it is important to maintain regular rest patterns and avoid excessive fatigue or staying up late.

What IV fluids should be administered for acute pancreatitis?

If the diagnosis confirms acute pancreatitis, venous medication generally involves the use of proton pump inhibitors to suppress gastric acid, which also helps reduce the secretion of pancreatic enzymes. Meanwhile, to prevent infection, antibiotics can be used appropriately. Medications that reduce pancreatic secretion, such as octreotide or somatostatin, can be considered, as well as drugs that inhibit pancreatic enzyme activity. Since patients with pancreatitis must abstain from food and water intake, it is important to pay attention to energy intake and maintain electrolyte balance. Once acute pancreatitis is confirmed, it is essential to seek hospital treatment as this condition can be quite dangerous. All mentioned medications should be used under the guidance of a doctor.
