Insulin Resistance & Insulin therapy

Insulin resistance is a condition where the body's cells become less responsive to the effects of insulin, a hormone that helps regulate blood sugar levels. As a result, the pancreas produces more insulin to compensate for the reduced effectiveness. Over time, this can lead to elevated blood sugar levels and eventually type 2 diabetes. Insulin resistance is commonly associated with obesity, physical inactivity, poor diet, and genetic factors.

Insulin therapy is a treatment used to manage diabetes, particularly in type 1 diabetes or advanced type 2 diabetes, where the body no longer produces enough insulin. Insulin can be delivered through injections or insulin pumps and comes in various forms, including rapid-acting, long-acting, and intermediate-acting insulins, each with different time profiles and uses. In people with insulin resistance, insulin therapy may be required when the pancreas can no longer produce sufficient insulin to maintain normal blood sugar levels. While lifestyle changes (such as diet and exercise) are critical in managing insulin resistance, insulin therapy is often necessary to achieve optimal blood glucose control when resistance becomes significant.

The goal of insulin therapy is to keep blood glucose levels within a target range, prevent complications, and improve quality of life. However, it requires careful monitoring, as improper insulin use can lead to hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).
