Have you read up on the dawn phenomenon? It’s where your morning fasting glucose is elevated because of hormones released at that time of day. It happens in diabetics and non-diabetics, too.
Jenny Ruhl of Diabetes 101 has the first things I’ve ever read about it:
3.Dawn Phenomenon. If your blood sugar is highest first thing in the morning, and normalizes after you eat or exercise and stays normal hours after dinner, you may have a disturbance of regulatory hormones that is called “dawn phenomenon.”
Our bodies prepare for waking up by secreting stimulating hormones shortly before dawn. These increase our insulin resistance in order to raise blood sugar a small amount. If we were animals who had to go hunt for our first meal, that excess glucose would be useful. Since were are people with refrigerators, it is less so.
Everyone experiences this early morning hormone burst, but in people with diabetes it can become highly exaggerated. In some people it is resistant to any treatment, but once the person goes about their day and eats, the blood sugars become more controllable.
If you have dawn phenomenon that doesn’t respond to various lowering techniques, don’t panic. As long as you are spending most of the day with your blood sugars at a safe level (Always under 140 mg/dl and under 120 mg/dl as much as possible) you’ll be fine.
Hope this helps!
