The causes of delayed insulin secretion include endocrine disorders caused by lesions of the secretory organs such as pancreatic diseases or psychological causes such as poor mood. 1. Diseases of secretory organs. Insulin is secreted by pancreatic β-cells. Pancreatic diseases such as diabetes mellitus, pancreatitis, pancreatic cysts or pancreatic cancer can affect the function of pancreatic islets, which in turn leads to delayed insulin secretion. At this time, patients should be further examined to find the primary disease and take appropriate treatment measures to solve the problem under the guidance of professional doctors. 2. Psychological reasons. When the mood is unstable, it will affect the endocrine function of the human body, and the delay of insulin secretion may also occur at this time. At this time, it is necessary to actively adjust the mood, insulin secretion delay can be restored to normal. If the delayed secretion of insulin occurs, it is recommended to go to the hospital in time, under the guidance of the doctor for the next step in the treatment.
