Insulin oscillation blood from the pancreas to the liver, which is a major insulin target. Disturbances of the insulin oscillations occur early in type 2 diabetes and may contribute to insulin resistance. Pulsatile insulin delivery to the portal vein or islet cell transplantation to the liver of diabetic patients are therefore attractive therapeutic alternatives. Insulin oscillation The insulin concentration in blood increases after meals and gradually returns to basal levels during the next 1–2 hours. However, the basal insulin level is not stable. It oscillates with a regular period of 3-6 min. After a meal the amplitude of these oscillations increases but
Insulin of a rapid acting and a protracted insulin is also available, making it more likely for patients to achieve an insulin profile that mimics that of the body´s own insulin release. Insulin is usually taken as subcutaneous injections by single-use syringes with needles, via an insulin pump, or by repeated-use insulin pens with disposable needles. Inhaled insulin is also available in the U.S. market now. Synthetic insulin can trigger adverse effects, so some people with diabetes rely on animal-source insulin. Unlike many medicines, insulin currently cannot be taken orally because, like nearly all other proteins introduced into the gastrointestinal tract,
