Acute pancreatitis is a relatively serious disease that has a very significant impact on the physical and mental health of patients. After the onset of acute pancreatitis, its symptoms are actually multifaceted, such as sudden onset of right upper abdominal cramps, nausea and vomiting, acute abdomen, jaundice, fever, diarrhea, feeling of banding in the upper abdomen and lower back, and a series of other symptoms. Acute pancreatitis with different etiology and different pathological types may also have different clinical symptom manifestations. In case of simple edematous acute pancreatitis, the symptoms will be mild and generally confined to the abdomen. In contrast, the symptoms of hemorrhagic or necrotizing acute pancreatitis are more severe, and symptoms may appear in the abdomen and the whole body, such as fever and shock. Biliary pancreatitis is usually accompanied by severe jaundice, and this type of acute pancreatitis is usually caused by gallstones or lesions in the biliary system. The symptoms of jaundice can occur because it affects the normal drainage of bile. Acute pancreatitis attacks are followed by severe abdominal pain and therefore frequent vomiting, which is also a defensive reflex of the body to abdominal pain and pancreatic inflammatory stimuli. If these symptoms occur after drinking a lot of alcohol or eating a lot of food, you should highly suspect that it is caused by acute pancreatitis and should immediately go to the hospital for treatment, otherwise there is a possibility of death.
