Insulin: How It Works

Insulin is a hormone that helps your body control the amount of sugar (glucose) in your blood. It is produced by the pancreas, a large gland that is located in the abdomen behind your stomach. How does insulin work? Insulin is produced in the islets of Langerhans (pancreatic islets), which are small isolated clumps of special cells in the pancreas. Insulin works alongside glucagon, another hormone produced by the pancreas, to manage the levels of glucose in your blood. Both insulin and glucagon are secreted directly into your bloodstream, and work together to regulate your blood glucose levels. Insulin should stop your blood sugar from rising too high and glucagon should prevent it from becoming too low. Insulin is produced by the beta cells of the pancreatic islets. Insulin is released when you have just eaten a meal and the level of glucose in your bloodstream is high. It works by stimulating the uptake of glucose into cells, lowering your blood sugar level. Your liver and muscles can take up glucose either for immediate energy or to be stored as glycogen until it’s needed. Glucagon is produced by the alpha cells of the pancreatic islets. It is released when your blood sugar le Continue reading >>

    Insulin Injections and Insulin Resistance?

    Will going on Insulin Injections too early cause Insulin Resistance in the future? Does the body build a resistance to the Insulin over time?

    If you gain weight with insulin (which is likely unless on strict diet and exercise), then yes, insulin resistance will go up over time. I would work on the diet and exercise part first to lower the insulin resistance.

    If you can keep your insulin levels modest then this may not have much of an effect. If you increase your insulin levels too high then this does make you fat and also worsens insulin resistance to be sure. So the main problem here is that this causes the liver to make too much fat and this fat kills beta cells and also raises the hormone that puts our blood sugar up. This is actually the big thing with insulin, this all causes cells to be less sensitive to it, especially the alpha cells in the pancreas which is what puts our blood sugar up.
    Since this all happens from too much fat storage, and this fat storage is driven by both insulin and carb intake, if you are on insulin then watching your carb intake is critical. Insulin is the fire, carbs is the wood. The overconsumption of carbs also drives insulin up so you have the wood stoking the fire more as well, and if you use insulin you can really go high. Some people here do fine on a little insulin though because they watch their carbs closely.

    Insulin is a hormone made by one of the body's organs called the pancreas. Insulin helps your body turn blood sugar (glucose) into energy. It also helps your body store it in your muscles, fat cells, and liver to use later, when your body needs it. After you eat, your blood sugar (glucose) rises. This rise in glucose triggers your pancreas to release insulin into the bloodstream. Insulin travels through the blood to your body's cells. It tells th ...
