Insulin is secreted by the beta cells of the pancreas in response to high blood sugar, although a low level of insulin is always secreted by the pancreas. After a meal, the amount of insulin secreted into the blood increases as the blood glucose rises.lood glucose is normally maintained between 70 mg/dl and 110 mg/dl. Blood glucose levels below 70mg/dl, denote the situation of hypoglycemia. Although blood glucose levels of 110mg/dl can be normal, this is only the case if a meal has been taken within 2 to 3 hours.
Hemoglobin A1c: A minor component of hemoglobin to which glucose is bound. Abbreviated HbA1c. HbA1c levels depend on the blood glucose concentration: The higher the glucose concentration in blood, the higher the level of HbA1c.Levels of HbA1c are not influenced by daily fluctuations in the blood glucose concentration but reflect the average glucose levels over the prior 6 to 8 weeks.bA1c levels depend on the blood glucose concentration: The higher the glucose concentration in blood, the higher the level of HbA1c.
