Insulin resistance is the condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. Insulin resistance in fat cells results in hydrolysis of stored triglycerides, which elevates free fatty acids in the blood plasma. Insulin resistance in muscle reduces glucose uptake whereas insulin resistance in liver reduces glucose storage, with both effects serving to elevate blood glucose. High plasma levels of insulin and glucose due to insulin resistance often leads to the metabolic syndrome and type 2 diabetes.
Pathophysiology
In patients who use insulin, "insulin resistance" is production of antibodies against insulin that lead to lower-than-expected falls of glucose levels (glycemia) after a given dose of insulin. With the development of human insulin and analogues in the 1980's and the decline in the use of animal insulins (e.g., pork, beef), this type of insulin resistance has become very uncommon.
The most common type of insulin resistance is associated with obesity and metabolic syndrome. This was first described in the 1930's by H.P. (Harry) Himsworth (University College Hospital Medical School, London). He described results of experiments in an article in 1936, entitled, "Diabetes Mellitus: Its differentiation into insulin sensitive and insulin insensitive types." He found that those with diabetes can be differentiated into two types: those in whom injected insulin produces an immediate suppression of hyperglycemia; and those in whom the insulin has little or no effect. Hyperglycemia itself can lead to insulin resistance, but N-acetylcysteine and taurine can prevent this effect.
