Early morning highs in blood glucose are common in people with diabetes. This is known as the dawn phenomenon, also called the dawn effect, and describes an abnormal increase in blood sugar, usually between 2 a.m. and 8 a.m. Insufficient glucose lowering hormone the night before, incorrect anti-diabetic medication dosages or eating carbohydrates at bedtime could also lead to high morning blood sugar. If your fasting glucose continues to be high, talk to your healthcare provider about options that may work with your lifestyle and regimen.
