Pancreatic tail resection may produce dyspepsia, hyperglycemia and other sequelae. 1. Dyspepsia: The most common sequela of pancreatic tail resection is dyspepsia. It is mainly because the pancreas is the main organ that secretes pancreatic juice, and the digestive juice will be reduced after pancreatic tail resection, thus affecting the digestive function. Especially when patients consume high fat or high protein food, they will be more likely to have abdominal discomfort and may even have diarrhea. 2. Hyperglycemia: the resection of the tail of the pancreas may also lead to hyperglycemia. Insulin is mainly secreted by the pancreatic islets in the pancreas, and the islets at the tail of the pancreas are most widely distributed. After the removal of the tail of the pancreas, the secretion of insulin will be reduced, and when the insulin secretion is insufficient, it is easy to cause high blood glucose, and in serious cases, it may even lead to diabetes mellitus. After the removal of the tail of the pancreas, it is recommended that patients should strictly control their diet and avoid eating too much high-fat, high-sugar and high-protein food. If you find that your blood sugar rises, you should go to the hospital in time to take treatment.
