What is Insulin and how does it work?

Insulin is a hormone produced by the pancreas, the organ situated behind the stomach. When insulin is absent, or is deficient, or is defective, sugar (glucose) cannot enter the cells and remains in blood in high amounts. Causing Diabetes When diabetes progresses, insulin becomes inevitable. After injection, insulin enters the bloodstream and is carried throughout the body where it acts by attaching itself onto cell surfaces and allows sugar to enter the cells. Who needs Insulin Injections? Persons with type 1 diabetes are dependent on insulin injections as their pancreas is unable to produce insulin. In type 2 diabetes, there may be periods (e.g. during illness, surgery or pregnancy) when an otherwise effective tablet treatment has to be temporarily replaced by insulin treatment. In addition, many patients with type 2 diabetes do much better on a daily insulin injection, especially when tablets are no longer effective. The decision about whether you require insulin is best made by your doctor. Don't have any aversion for insulin.
