The most important treatment for people with type 2 diabetes is maintaining a healthy body weight. If someone is overweight with type 2 diabetes, they really need to make healthy food choices, reduce their caloric intake, be more physically active, and lose weight. When they achieve a healthy body weight, they need to keep being active with diet and exercise in order to maintain it. With type 2 diabetes, there are around a dozen medications that are approved for treating it in addition to diet and exercise when that is not enough. Some of those medications are injectable and some of those are pills Ð it really depends on what kind of diabetes and where you are, which one is right for you.
