Insulin Insulin Insulin (from Latin "insula", island) is a peptide hormone produced by beta cells of the pancreatic islets; it is considered to be the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of carbohydrates, especially glucose from the blood into liver, fat and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the case of the liver, into both. Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in
Insulin pump being injected, or if the cannula becomes bent or kinked in the body, preventing delivery. Therefore, pump users typically monitor their blood sugars more frequently to evaluate the effectiveness of insulin delivery. Use of insulin pumps is increasing because of: In 1963 Dr. Arnold Kadish designed the first insulin pump to be worn as a backpack. A more wearable version was later devised by Dean Kamen in 1976. Kamen formed a company called "AutoSyringe" to market the product, which he sold to Baxter Health Care in 1981. The insulin pump was first endorsed in the United Kingdom in 2003, by
