Insulin resistance is a condition in which the body's cells become less sensitive to insulin, a hormone that regulates blood sugar levels. As a reaction to this, the body produces more and more insulin, which still cannot metabolise the sugar. It thus leads to high levels of both sugar and insulin in the bloodstream.
Over time, this can lead to the development of type 2 diabetes and other health problems, such as heart disease, stroke, and kidney disease.
Insulin resistance is often associated with obesity, a sedentary lifestyle, and a diet high in processed foods and sugar. However, it can also occur in people who are not overweight and who lead an active lifestyle. Treatment for insulin resistance may include lifestyle changes, such as exercise and dietary modifications, as well as medications to help regulate blood sugar levels.
