My blood sugar is within range most of the day except when I wake up in the morning. I do not take medication at this time but when I did it was also high in the morning maybe 20 points.
This is possibly due to the "dawn effect".
The "dawn effect," also called the "dawn phenomenon," is the term used to describe an abnormal early-morning increase in blood sugar — usually between 2 a.m. and 8 a.m.
Some researchers believe it's due to the natural overnight release of hormones — including growth hormones, cortisol, glucagon and epinephrine — that increase insulin resistance (a condition where insulin, becomes less effective at lowering blood sugars).
High morning blood sugar may also have other causes. Insufficient insulin the night before, incorrect medication dosages or eating carbohydrate snacks at bedtime may cause blood sugar to be elevated in the morning. When necessary, checking your blood sugars once during the night — around 2 a.m. or 3 a.m. — will help you and your doctor to determine if you have the dawn phenomenon or if there's another reason for an elevated morning blood sugar reading.
Based on the results of blood testing throughout the night, your doctor may recommend one of the following options to prevent or correct high blood sugar levels in the morning:
Not eating a carbohydrate snack at bedtime
Adjusting your dosage of medication or insulin
Switching to a different medication
Using an insulin pump to administer extra insulin during early-morning hours
Hope this helps.
