For type 2 diabetes, as long as your body is making enough insulin, you won't need insulin injections. Sometimes lifestyle modifications are sufficient to keep type 2 under control in the early years, but many types of medications can help those with type 2 diabetes lower their blood glucose by such means as stimulating insulin production, decreasing the amount of glucose made by the liver, slowing starch absorption and boosting insulin sensitivity. You and your health care professional can decide what is best for you.
