Pancreatitis is a disease belonging to gastroenterology, so there are many digestive symptoms manifested, among which patients with hyperlipidemia or hypercalcemia are more likely to be more frequent. First of all, we need to understand the physiological structure and function of the pancreas. Under normal circumstances, pancreatic juice contains pancreatic zymogen in the glandular tissue, which is then shown to be inactive. However, when it flows through the common bile duct to the duodenum, it undergoes a series of chemical reactions, such as the mixing of bile and enterokinase, and the pancreatic zymogen is transformed into a highly active digestive enzyme. Therefore, if its outflow duct is blocked at this time and cannot be excreted properly, then pancreatitis will be caused. In addition, patients with stones or tumors can easily cause spasm of the common bile duct or increased pressure, which can lead to bile reflux and cause pancreatitis. The common causes of pancreatitis are biliary tract diseases, infections, or poor diet and alcohol abuse, often accompanied by abdominal pain, abdominal distension, nausea, vomiting, and fever. In laboratory tests, we can use white blood cell count and blood and urine amylase to assist in the diagnosis, and depending on the actual situation, we can take surgical or non-surgical treatment. Therefore, we must regulate our diet, not to drink alcohol to harm our body, and do physical examination on time in order to effectively prevent the occurrence of pancreatitis.
