Question from Nashville, Tennessee, USA:

When I go to bed at night, my blood sugar will be 106-125 mg/dl [5.9-6.9 mmol/L], and when I get up in the morning, it is always 130-137 mg/dl [7.2-7.6 mmol/L]. What causes my sugar to go up when I sleep?


This is a common problem in type 2 diabetes. Your liver converts stored sugar (or glucose) back into sugar in your blood. Ask your doctor if you may be a candidate for metformin, an insulin sensitizer that works very well in preventing the liver from producing excess glucose.
