No one knows why high glucose levels cause complications in people with diabetes. But keeping glucose levels as low as possible prevents or slows some complications.
For the Diabetes Control and Complications Trial, researchers followed 1,441 people with type 1 diabetes for several years. Half of the people continued standard diabetes treatment while the other half followed an intensive-control program. Those on intensive control kept their blood glucose levels lower than those on standard treatment, although the average level was still above normal.
Bottom line: For better help, talk with your doctor about all the ways you can help keep your diabetes under control.
