However, people with type 2 diabetes usually produce some of their own insulin, at least at the point of diagnosis. It's insulin resistance that's the problem. Insulin normally ferries glucose from the bloodstream into muscles. When the body loses sensitivity to insulin, it can't transport glucose out of the blood as efficiently, and blood-sugar levels rise.
The American Diabetes Association recommends that patients initially treat their type 2 diabetes with lifestyle changes (improved diet, more exercise, and weight loss) and the oral diabetes drug metformin. Losing 5% to 7% of your body weight can considerably improve your blood-glucose levels. For many people, that means losing as little as 7 to 10 pounds.
