Insulin resistance is a condition where the body's cells become less responsive to insulin, a hormone that helps regulate blood sugar levels. This reduced sensitivity means that higher amounts of insulin are necessary to effectively manage glucose, leading to escalating insulin levels in the bloodstream. Insulin resistance is closely linked to type 2 diabetes, as prolonged resistance can result in the pancreas being unable to produce enough insulin to maintain normal blood sugar levels. This can contribute to various health complications, including cardiovascular diseases, fatty liver disease, and other metabolic disorders. Lifestyle changes, such as improved diet and increased physical activity, are crucial for management.
