The Dawn effect, also called the Dawn Phenomenon is the term used to describe an abnormal early morning increase in blood sugar. (usually between 4a.m. and 8a.m.) in people with diabetes. This phenomenon is more common in people with type 1 diabetes than those with type 2 diabetes.
The exact cause is not known. Some researchers believe it's due to the natural overnight release of hormones. Such as cortisol, epinephrine, and glucagon, which normally increase insulin resistance.
High morning or a.m. sugars may also have a myriad of other reasons. Such as insufficient insulin the night before. a bigger meal than planned, carbohydrate snacks at bedtime. Checking your sugars through the night may provide some insight into what the issue may be.
Based on your nighttime log,or insulin log, you and your Dr. may decide on several factors. to increase your p.m. insulin dose, change your snacks or not eating a bedtime snack, changing medications.
It's difficult to say as everyone is affected so differently. A log is the best bet as it will provide ideas as to what you can do.
Good luck and don't give up!
