The role of insulin in the body. It may be easier to understand the importance of insulin therapy if you understand how insulin normally works in the body and what happens when you have diabetes. Regulate sugar in your bloodstream. The main job of insulin is to keep the level of glucose in the bloodstream within a normal range.
Back to basics. Insulin is a hormone secreted by the pancreas that helps regulate the way the body uses glucose. Its main job is to allow glucose in the blood to enter cells of the body where it can be used for energy. In people who donât have diabetes, the pancreas changes how much insulin it releases depending on blood glucose levels. Eating a chocolate bar? The pancreas releases more insulin. Sleeping? The pancreas releases less insulin until the wee hours of the morning when the hormones secreted in the early morning naturally increase insulin resistance, so the pancreas needs to release a little more. Insulin also controls how much glucose is produced and released from the liver.
