When the body no longer responds well to insulin, it has become insensitive, or resistant. Someone then has insulin resistance. Insulin is the hormone that lowers the blood sugar level. It keeps the blood sugar level in balance. As soon as the body no longer reacts well to insulin, too much blood sugar remains unused in the blood and that is unhealthy.

Also losing weight and more exercise make the body more sensitive to insulin. That is why they are such important advice in the treatment of type 2 diabetes.
Causes of insulin resistance
The causes of insulin resistance are mainly overweight and too little physical activity.
