My Doctor has at times diagnosed me as type 2 without complications and pre-diabetic or hyperglycemic. My doctor is not an endocrinologist but I understand many of them see the issue in similar fashion. Dawn phenomenon as it has been explained to me is a normal physiological process that occurs in everyone diabetics (type 1 and 2) as well as non diabetics. Diabetics inability to produce sufficient insulin or utilize it effectively (insulin resistance) cause sugar numbers to rise higher in the early morning hours. Not to confuse you but type 1 diabetics who are insulin users also experience a similar issue due to insulin dosing or usage and rebound sugars known as the somogyi effect which is addressable my better dosing control. I believe dawn phenomenon can also be controlled by strict dieting, including the reduction of evening carbohydrates and limiting hours of eating I.e., eating all meals within an 8 hr period within a 24hr day the 16:8 diet plan.
