Why is my Blood Sugar Levels Higher in the Morning?


Whether you have diabetes, pre-diabetes or simply are at risk for blood sugar disorders, it is possible that your blood sugar levels are highest in the morning.

Having high blood sugar levels even before eating the first meal of the day can be quite puzzling and can lead to elevated blood sugar levels throughout the day.

Understanding the causes of high morning blood sugar levels is the first step in correcting the problem and better managing your blood sugar levels, which should be between 3.88 and 7.2 mmol/L if you have diabetes and 3.88 to 5.5 mmol/L if you do not have diabetes.

Somogyi Effect

The Somogyi effect can be responsible for your high morning blood sugar levels, but this problem is most likely to happen if you have diabetes and take diabetes medications or insulin as part of your treatment.

The Somogyi effect refers to a rebound hyperglycemia, which means that after dropping too low, your blood sugar levels rise too much and reach a level above the normal range.

Dawn Phenomenon

Another reason for high morning blood sugar might be the dawn phenomenon. Right around sunrise, your body naturally becomes more resistant to the action of insulin, and insulin resistance is associated with increased blood sugar levels. Moreover, as your body is getting ready for a new day, it releases some sugar that was stored in the liver, which can also contribute to your elevated blood sugar levels in the morning.

Carbohydrate Overconsumption

The main nutrient influencing your blood sugar levels is carbohydrates. Found in grains, starchy vegetables, sugar and fruits, carbohydrates are broken down into glucose, a form of sugar. If you eat too many carbs at once, a lot of glucose will be entering your bloodstream, and it might take some time for your body to process it all.

If you consume large amounts of carbs the previous night at dinner or during the evening, whether it is a large plate of pasta, french fries, soft drinks, cakes, potato chips or cookies, your morning blood sugar levels might reflect carb overconsumption.

What to Do

If your blood sugar levels are high in the morning, you will need to figure out what is causing this problem. Tracking your blood sugar levels at various times of the day and your food intake can help you see if there is a pattern between what you eat at night and your blood sugar levels the next morning.

You can also check your blood sugar levels around 3 a.m. to see whether you experience a drop in your blood sugar levels, which could result in a rebound high blood sugar in the morning. Consult your doctor or diabetes team to see what changes you could make to your treatment plan to optimize your morning blood sugar levels.
