IR meaning in Medical ?

Insulin resistance (IR) is a pathological condition in which cells fail to respond normally to the hormone insulin.

Insulin is a hormone that allows glucose to enter cells which also reduces blood glucose (blood sugar). Insulin is released by the pancreas in response to carbohydrates consumed in the diet. In states of insulin resistance, the same amount of insulin does not have the same effect on glucose transport and blood sugar levels. There are many causes of insulin resistance and the underlying process is still not completely understood. But sulphate depletion may be the important factor. Risk factors for insulin resistance include obesity, sedentary lifestyle, family history of diabetes, various health conditions, and certain medications. Insulin resistance is considered a component of the metabolic syndrome. There are multiple ways to measure insulin resistance such as fasting insulin levels or glucose tolerance tests but these are not often used in clinical practice. Insulin resistance can be improved or reversed with lifestyle approaches such as exercise and dietary changes.
