Patients with pancreatitis may experience wasting. In the case of acute pancreatitis, fasting is required in the early stage of the disease, and then as the disease subsides, it is changed to an oil-free semi-liquid diet and gradually transitioned to an oil-reduced semi-liquid diet, and then finally returned to a normal light diet. Therefore, throughout the treatment of acute pancreatitis, and until the recovery of the disease, the patient’s eating amount is relatively small. Because of eating less, the nutrients will be less absorbed, and the patient will appear to lose weight. The main clinical manifestations of chronic pancreatitis patients are diarrhea, steatorrhea, emaciation, abdominal pain, abdominal distension, etc. Because chronic pancreatitis will appear pancreatic exocrine insufficiency, so the secretion of pancreatic lipase, pancreatic protease will be significantly reduced, which will lead to the patient to eat the food is not absorbed, not digested, and so will cause the symptoms of diarrhea, then the patient will be naturally occurring in the emaciation of the situation. However, for patients with emaciation, it is also necessary to pay attention to exclude other special diseases such as malignant tumors, so it is recommended that patients need to go to the hospital when necessary to improve the relevant examinations to clearly exclude.
