Insulin; Vital Hormone

Insulin is a hormone produced by the pancreas, a small organ located behind the stomach with many vital functions. The islet cells within the pancreas secrete insulin. What Does Insulin Do?Insulin allows glucose to enter the body’s cells, which grab the insulin and convert it into energy. When the body detects an increase in blood glucose after a meal, the pancreas secretes insulin. The cells in the bloodstream grab the insulin, which activates receptors that allow the cells to absorb the glucose into the cell. Insulin is like a key, it opens the door of the cell to allow the glucose in the bloodstream to enter it.Without insulin, the body can actually begin to starve, as the cells would not be able to absorb the glucose and convert it into energy. Over time, the build up of glucose in the bloodstream will also cause serious complications. As you can see, insulin is a vital hormone.Insulin and DiabetesIn type 1 diabetes, the body generates antibodies that kill the betta cells within the islet cells, which produce insulin. Type 1 diabetics need to have insulin shots or use insulin pumps in order to control their blood glucose levels.People with type 2 diabetes usually develop insulin resistance, where although the levels of insulin in the body are normal, the body cannot properly use the insulin, causing the glucose to build up in the bloodstream. Type 2 diabetics need insulin shots sometimes, but mostly treatment includes a healthy diet, weight loss and regular physical activity.Types of insulinInsulin is classified by how fast it begins to work and how long the effects last. Based on factors like your body’s natural reaction to the insulin, your lifestyle choices and your age, the doctor will determine which type of insulin is appropriate for you.Types of insulin include:Rapid Acting: Starts to lower blood glucose within 5 to 10 minutes and lasts 3 to 5 hoursShort Acting: Stars to lower blood sugar with 30 minutes and lasts 5 to 8 hoursIntermediate Acting: Starts to lower blood sugar levels within 1 to 2 hours and lasts 18 to 24 hours.Long Acting: Starts to lower blood glucose four to six hours after injection and lasts 20 to 36 hours, depending on the type and brand that is usedPremixed insulin: Combination of intermediate acting and short acting insulin.ConclusionIf you have pre diabetes, type 1 diabetes, type 2 diabetes or insulin resistance, it is important that you educate yourself as much as you can on your condition and on the important functions of insulin. Talk to your health care professional and discuss which treatment options and insulin types are right for you.
