Why is my blood glucose so much higher in the morning before I eat than it was the night before?
When we are not eating, as happens overnight, our liver produces glucoseas the body’s way of keeping blood glucose levels from going too low. Think of the liver as a glucose-making machine and insulin as the switch that makes the machine turn on or off. However, when you don’t have enough insulin in the blood stream, the liver loses its ability to to regulate itself. This is why people with diabetes can go to bed with a blood glucose level in range and wake up with a reading that is elevated, causing a lot of frustration and confusion. The best way to treat this problem is with medications that either decrease glucose production in the liver (metformin), or increase insulin in the bloodstream (sulfonylureas or injected insulin). Some research has indicated that a lowfat low-carb, high-protein snack in the evening, such as cottage cheese or turkey breast, might also help.
