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 is acute severe pancreatitis?

Acute severe pancreatitis is caused by many reasons, including binge eating, especially consuming a large amount of high-fat diet, excessive drinking, obstruction of the pancreatic duct by gallstones in the bile duct, pregnancy, hyperlipidemia, etc. These lead to disorders in pancreatic secretion, resulting in pancreatic juices digesting the pancreas itself and leaking into the abdominal cavity, leading to symptoms such as abdominal effusion. It is classified as severe pancreatitis based on reaching a certain score in some assessments. Severe pancreatitis often accompanies dysfunction of organ systems, common examples include acute respiratory distress syndrome characterized by stubborn hypoxia and respiratory failure, acute renal failure shown by anuria or oliguria, and acute gastrointestinal failure, which manifests as high abdominal pressure and severe intestinal motility disorders, including abdominal distension.

How long will the fever last in acute pancreatitis?

Patients with acute pancreatitis may experience different symptoms based on the cause of the pancreatitis and the staging of the patient's condition. A fever in acute pancreatitis indicates a severe infection. If a CT scan shows extensive pancreatic effusion, coupled with hyperglycemia and hypocalcemia, it suggests that the condition is severe and there is a tendency towards severe pancreatitis. This type of fever generally requires treatment, sometimes even surgical intervention, and usually takes about half a month to a month to subside. If the fever is caused solely by biliary pancreatitis due to bile duct obstruction by gallstones, and surgical intervention to remove the obstruction is performed, the fever will typically diminish significantly in the short term.

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.

Does acute pancreatitis have anything to do with the stomach?

Acute pancreatitis is not closely related to stomach conditions, although it is sometimes associated with overeating, but it is not caused by stomach diseases in patients. Instead, it relates to lifestyle habits. The occurrence of pancreatitis is often considered to be due to biliary, alcoholic, hyperlipidemia, and idiopathic causes. In China, the most common causes are biliary and alcohol-related. Biliary causes are mainly related to gallstones, while alcohol-related causes are mostly associated with drinking. Common stomach diseases include gastritis, ulcers, and stomach cancer. These conditions can sometimes cause an increase in amylase during acute abdominal conditions, but they do not cause acute pancreatitis.

Can you drink water with acute pancreatitis?

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.
