Acute pancreatitis often occurs following gallstones, hyperlipidemia, and alcohol consumption. Patients with acute pancreatitis sometimes exhibit clear symptoms, including fever. This is due to the significant inflammatory irritation and the extravasation of pancreatic juices, causing infection and effusion around the pancreatic tissue. If not treated promptly, the fever may persist. Therefore, after diagnosing acute pancreatitis, treatments such as dietary restrictions, gastrointestinal decompression, enzyme inhibition, acid suppression, correction of fluid and electrolyte balance, and anti-infection measures should be taken. These treatments can delay or alleviate the progression of acute pancreatitis and help the patient's body recover sooner, thereby reducing the fever.
