Patients with acute pancreatitis cannot drink water or eat anything during the acute phase. They must undergo gastrointestinal decompression to suction out gastric juice, gastric acid, and gastric contents. At the same time, treatment for acute pancreatitis includes inhibiting pancreatic secretion, anti-infection measures, intravenous fluid replenishment, and maintaining electrolyte balance, among others. If a patient with acute pancreatitis experiences bowel movements, gas, relief from abdominal pain, and a decrease in blood amylase to normal levels, they may then consider drinking small amounts of water and consuming light foods like rice soup or thin porridge. If the abdominal pain disappears, the patient can gradually increase their water intake.
