The body needs insulin for the metabolism of glucose. The insulin is an hormone that is secreted by the islets of Langerhans in the pancreas. The insulin enables the cell's gates to open so that the glucose in the blood can enter the cells. This enables the cells to retain the blood glucose levels in the blood and also helps the body to maintain the required optimum amount of glucose in the body - about 90 mg glucose/ 100 ml of blood. For artificial insulin dosage, the amount of insulin that is needed is 8 unit SC at lunch and 12 units SC qhs. This is ideal for a health patient.
