Many people living with diabetes experience high blood sugar levels in the morning. There are a few reasons you may notice high numbers when you wake up.
- Food choices: Your evening meal or late-night snack could be contributing to higher a.m. numbers. Meals containing carbs and fat tend to send your blood sugar up and keep it up longer.
- Hormones: Your body releases natural hormones overnight and in the early hours of the day. This causes your liver to produce sugar. This can lead to high morning blood sugar.
- Medication: The timing or type of diabetes meds you take may need to be adjusted.
What’s the target range for my fasting blood sugar?
Diabetes Canada recommends a fasting blood sugar level of 4.0-7.0 mmol/L.
What can I do to get my blood sugar in target range?
Improving a high fasting blood sugar can depend on what’s causing it in the first place.
If you eat a late dinner:
Try having a lighter dinner. A lean source of protein, non-starchy veggies, a serving of healthy fat may do the trick. For example a bed of spinach with 3 ounces of grilled chicken breast, 1-2 tablespoons of light dressing, and string cheese.
You eat a healthy dinner but your a.m. blood sugar is high anyway:
Talk to your doctor. You may need to have your meds adjusted.
Your blood sugar drops low in the middle of the night and is high when you wake up:
Talk to your doctor about changing your meds. You may also need to add in a bedtime snack that includes 15 grams of carbs paired with a serving of protein. If you are exercising in the evening, try working out earlier in the day.
Regardless of the cause, you can also try:
- Eating dinner earlier
- Going for an after-dinner walk
-
Having a balanced evening snack that includes protein and healthy carbs. Examples:
- Small apple with 1 tablespoon of peanut butter
- ½ turkey sandwich on whole-wheat bread
- 1 6-ounce Greek yogurt
- ½ cup low-fat cottage cheese with 1 cup of blueberries
