About High Blood Sugar
Normal blood sugar measures 70 to 99 milligrams per deciliter after fasting, or less than 140 milligrams per deciliter two hours after eating.

Surge in Hormones
Between the hours of 4 and 5 a.m., most people, whether they have diabetes or not, have a surge in hormones called the "dawn phenomenon." People with diabetes also experience an increase in blood sugar during this time because their body is producing glucagon -- a hormone that raises blood sugar -- but their insulin is not able to compensate for the rise in blood sugar, leading to even higher levels.
