What you may be experiencing is what is commonly referred to as the "dawn phenomenon". This is where blood sugar becomes elevated between 2-8am. This happens when your blood glucose goes low in the evening. The body compensates by releasing stored glucose from the liver. In people without diabetes the body would simply produce more insulin and regulate ...
