Insulin even be slightly over-corrected) by the end of the test. Even during digestion, in general, one or two hours following a meal, insulin release from the pancreas is not continuous, but oscillates with a period of 3–6 minutes, changing from generating a blood insulin concentration more than about 800 p mol/l to less than 100 pmol/l. This is thought to avoid downregulation of insulin receptors in target cells, and to assist the liver in extracting insulin from the blood. This oscillation is important to consider when administering insulin-stimulating medication, since it is the oscillating blood concentration of insulin release, which
Insulin resistance with insulin resistance. It is hypothesized that increasing cell membrane fluidity by increasing PUFA concentration might result in an enhanced number of insulin receptors, an increased affinity of insulin to its receptors, and a reduced insulin resistance, and vice versa. Many stressing factors may lead to increased cortisol in the bloodstream. Cortisol counteracts insulin, contributes to hyperglycemia-causing hepatic gluconeogenesis, and inhibits the peripheral utilization of glucose, which eventually leads to insulin resistance. It does this by decreasing the translocation of glucose transporters (especially GLUT4) to the cell membrane. Inflammation by itself also seems to be implicated in causing insulin resistance.
