In brief: Liver produces sugar
The liver breaks down glycogen to glucose overnight when one is asleep, in order to feed the body (when not eating).
In people with type 2 diabetes, this liver production of glucose is exaggerated, and often times leads to elevated fasting morning glucose levels, which may actually be higher than the readings from the nights before. There are medications that can help to control this.
