The claim of 8 precursors of a bad pancreas is not true. A bad pancreas is considered to be the result of acute pancreatitis, chronic pancreatitis, pancreatic cancer and other diseases, in which the patient experiences typical manifestations such as pain in the upper and middle abdomen, nausea and vomiting. Pancreatic diseases usually have no precursors, so there is no such thing as 8 precursors of a bad pancreas. If a patient has acute pancreatitis there will be pain in the upper and middle abdomen, nausea and vomiting, abdominal distension, fever, pallor, restlessness and other manifestations of a bad pancreas. If the patient has chronic pancreatitis, he or she will have epigastric pain that radiates to the lower back. In addition, patients will also experience symptoms of bad pancreas such as loss of appetite, fullness after meals, weight loss, and diabetes. Patients with pancreatic cancer will also have bad pancreas manifestations, such as persistent and progressive upper and middle abdominal pain, yellowish skin sclera, yellow urine color, lethargy, fatigue, and loss of appetite. The 8 precursors of a bad pancreas are folklore, there is no such thing in medicine. Bad pancreas is considered to be the result of a variety of causes, and patients need to seek medical treatment in time.
