Delayed insulin secretion is mainly a delay in the peak secretion of insulin by human pancreatic islet cells, not a decrease in the amount of insulin, but a decrease in the number and function of pancreatic islet B cells, which will cause a decrease in the uptake and utilization of glucose by the human liver and peripheral tissues, as well as a decrease in hepatic glycogen and an increase in gluconeogenesis in the body, leading to a persistent increase in postprandial blood glucose. Delayed insulin secretion usually means abnormal pancreatic function in the body, often accompanied by pancreatic diseases, such as pancreatitis, pancreatic cancer, etc. It is recommended that patients with delayed insulin secretion promptly go to the hospital for testing to avoid a serious rise in blood sugar in the body and induce adverse cardiovascular diseases.
