Insulin resistancemeans that the cells of the body have become resistant to the action of the hormone insulin. Insulin, secreted by the pancreas, is critical for the body's use of glucose for energy. When the cells of the body do not respond appropriately to insulin, glucose from the bloodstream cannot be taken up by cells and used for fuel. Consequently, the pancreas tries to compensate by producing even more insulin. When the pancreas cannot produce enough insulin,blood glucoselevels rise. Insulin resistance is a risk factor for the development ofdiabetesand its associated complications. Insulin resistance is a step in the development oftype 2 diabetesand often occurs years before a person develops diabetes. Insulin resistance has been referred to as prediabetes.
Insulin resistance typically does not produce any specific symptoms and is diagnosed by a blood test. Some symptoms and signs are described below that are often seen in people with the condition due to associated medical conditions.
