Blood sugar high in the mornings is called the Dawn Phenomenon. It's generally caused by gluconeogenesis, or delayed stomach emptying. Gluconeogenesis is caused by the liver, primarily; it is the creation of new glucose from dietary protein, or from amino acids released from muscles or other tissues. If one has enough insulin-making capability, then that suppresses the action. Also, it seems that the liver is much more prone to "deactivate" circulating insulin in the early morning hours; if you don't make enough insulin to overcome that, you'll see a rise in BG. Delayed stomach emptying, or gastroparesis, is where the diabetes has damaged some of the nerves that govern the muscles of the stomach, and intestines. Unless you've had elevated BG for a number of years, this likely isn't the problem, but you'd have to have tests done to make certain.
