Pancreatitis is mainly caused by the return of pancreatic juice and bile to the pancreas after bile duct obstruction, which makes the pancreas digest itself, thus causing some symptoms. It usually happens after eating greasy food or drinking a lot at night. It is an acute and severe disease, and severe pancreatitis may be life-threatening. The treatment is mainly to inhibit the secretion of pancreatic juice, including fasting and drinking and some drug inhibition, in addition to preventing infection, relieving spasm and relieving pain. It is not inflammation in the traditional sense, nor is it an early bacterial infection. This is a comprehensive treatment, and it is impossible to cure it by any medicine. Hospitalization must be considered.
