Insulin characterized by abnormally high blood glucose concentrations, and generalized body wasting. In type 2 diabetes mellitus the destruction of beta cells is less pronounced than in type 1 diabetes, and is not due to an autoimmune process. Instead there is an accumulation of amyloid in the pancreatic islets, which likely disrupts their anatomy and physiology. The pathogenesis of type 2 diabetes is not well understood but patients exhibit a reduced population of islet beta-cells, reduced secretory function of islet beta-cells that survive, and peripheral tissue insulin resistance. Type 2 diabetes is characterized by high rates of glucagon secretion into the
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
