Going to bed with normal blood sugars, but always waking up high?

You may be seeing the effects of something called dawn phenomenon. People living with Type 2 diabetes may see blood sugar shifts hallmarked by a rise in early morning blood sugars and high morning glucose readings, according to Diabetes Health.

Historically, this phenomenon was thought to only affect those with Type 1 diabetes.

What is "Dawn Phenomenon"?

This phenomenon reflects an abnormal early morning increase in blood sugars that usually happens between the hours of 2 a.m. and 8 a.m. according to the Mayo Clinic.

This is one of the reasons why your health practitioner may ask you to get up and check some middle-of-the-night blood sugars.

What causes this phenomenon?

Overnight, the body may release increased levels of glucose and hormones. The liver is the culprit for the glucose release and the hormones cortisol, glucagon and adrenalin may be thrown into the mix as well.

The end result is insulin resistance and/or extra glucose dumped into your blood stream in the wee-hours of the morning. All of this may equate to high morning blood sugars.

How do I know if this is affecting me?

Set your alarm clock between 2-3 a.m. and check overnight blood sugars to help pinpoint trending. Armed with this information at your next appointment, your health care provider can help you trouble shoot those pesky morning highs.

High sugars can also result from a bedtime snack, not enough insulin or a need for diabetes medications to be adjusted.

Researchers suggest a preventative approach with long acting insulin "before their A1c reaches above 7.0%."
