How much does dawn phenomenon raise blood sugar?

A 2013 study of people with type 2 diabetes found that the dawn phenomenon can increase A1C levels, a measure of average blood sugar levels over three months, by 0.4 percent.

Does dawn phenomenon affect A1C?

That’s because early morning spikes in blood sugar may lead to higher average blood sugar levels and the many health complications that stem from it. It has been suggested that the dawn phenomenon may lead to as much as a 0.4% increase in a person’s A1C levels—a measurement of average blood sugar levels over time.

How do you overcome the dawn phenomenon?


  1. Avoid carbohydrates at bedtime.
  2. Adjust your dose of medication or insulin.
  3. Switch to a different medication.
  4. Change the time when you take your medication or insulin from dinnertime to bedtime.
  5. Use an insulin pump to administer extra insulin during early-morning hours.

Do all diabetics have dawn phenomenon?

The Dawn Phenomenon

If you have diabetes, your body doesn’t release more insulin to match the early-morning rise in blood sugar. It’s called the dawn phenomenon, since it usually happens between 3 a.m. and 8 a.m. The dawn phenomenon happens to nearly everyone with diabetes.

Does dawn phenomenon go away?

It can be serious. According to the American Diabetes Association, “Some people with dawn phenomenon find that their glucose continues to rise until they eat in the morning. For others, levels will settle down a few hours after waking, regardless of whether or not they eat.”

How do I get my fasting blood sugar down?

For some people, having some protein or healthy fat with about 15 grams of carbohydrate before bed helps keep the morning fasting numbers in target range. Try having a small amount of peanut butter on a piece of whole grain bread or 1 oz of low-fat cheese and a small apple.

What should I eat before bed to avoid dawn phenomenon?

To combat the dawn phenomenon, eat a high-fiber, low-fat snack before bed. Whole-wheat crackers with cheese or an apple with peanut butter are two good choices. These foods will keep your blood sugar steady and prevent your liver from releasing too much glucose.

How do I stop my liver from dumping glucose?

They may suggest one of the following to help stabilise your morning blood sugar levels:

  1. Adjusting insulin dosage.
  2. Adjusting medication dosage.
  3. Switching to different medication.
  4. Switching to an insulin with a different profile of activity.
  5. Not eating carbohydrate snacks before bed.

Is intermittent fasting good for dawn phenomenon?

However, the impression of the dawn phenomenon is directly linked with insulin sensitivity or production. Improving insulin sensitivity through a low-carb diet and/or intermittent fasting, will reduce morning fasting blood glucose, and lessen the dawn phenomenon effect.

How do you stop your liver from releasing glucose?

Glycogen phosphorylase inhibition

IT IS IMPORTANT:  Is 121 OK for blood sugar?

One method to inhibit glucose release by the liver is to increase its storage as glycogen. In diabetic patients, hepatic glycogen synthesis is impaired83 and the stimulation of glycogen synthesis in skeletal muscle by insulin is stunted, contributing to insulin resistance84.

Is it better to take Trulicity in the morning or at night?

In studies, Trulicity has been proven to lower blood sugar levels. People taking Trulicity may notice better blood sugar numbers before eating in the morning (fasting blood sugar).

Why does my blood sugar spike at 3 am?

In the early morning hours, hormones (growth hormone, cortisol, and catecholamines) cause the liver to release large amounts of sugar into the bloodstream. For most people, the body produces insulin to control the rise in blood sugar. If the body doesn’t produce enough insulin, blood sugar levels can rise.

Why is my blood sugar so high when I’m not eating any carbs?

While protein typically has very little effect on blood glucose, in the absence of carbohydrates (such as a low carb meal) or insulin, it can raise blood glucose. Many individuals with diabetes who eat carb-free meals will take a bit of insulin to cover the difference.
