Low fasting insulin can be seen in physiologic conditions or in diseases such as type 1 diabetes, type 2 diabetes, and pancreatitis.
Insulin is secreted by pancreatic β-cells and is the only hormone in the body capable of lowering blood glucose, which can provide a basis for the diagnosis and typing of diabetes, and can also be used to diagnose diseases such as insulinoma.
Low fasting insulin may be caused by physiological factors, because fasting blood glucose will be low, insulin secretion will also drop accordingly, if there are no other uncomfortable symptoms generally do not need special treatment.
In addition, low fasting insulin may also be type 1 diabetes, type 1 diabetes pancreatic β-cells have been damaged leading to a decline in insulin secretion, fasting insulin and postprandial insulin are low; type 2 diabetes, pancreatic β-cell failure can also occur fasting insulin is low. In patients with pancreatitis, damage to pancreatic cells leads to a decrease in pancreatic β-cells, which can also cause a decrease in insulin.
Low fasting insulin can be determined by a doctor at a hospital.
