Insulin Resistance (IR)
Definition - What does Insulin Resistance (IR) mean?
Insulin resistance is a medical condition where the body does not effectively use the insulin it produces naturally. Insulin is a hormone produced by the pancreas which enables cells to utilize glucose as an energy source or to store it in the body's fat reserves. Insulin resistance causes the body to generate more insulin which increases blood sugar levels.
WorkplaceTesting explains Insulin Resistance (IR)
Insulin resistance is not identified by any physical symptoms and requires an A1C blood test for accurate diagnosis. However, increased blood sugar levels brought about by insulin resistance can cause an increase in appetite, weight, cholesterol, and blood pressure levels. Insulin resistance typically serves as an early indicator of pre-diabetes and type 2 diabetes. The cause of insulin resistance is not well understood but it is believed that several metabolic disorders may play a role, as well as certain lifestyle behaviors such as high calorie diets and low activity levels.
