What Is The Somogyi Effect

A second possible cause of high blood sugar levels in the morning is the Somogyi effect, sometimes also called rebound hyperglycemia. It was named after the doctor who first wrote about it.

If your blood sugar drops too low in the middle of the night while you are sleeping, your body will release hormones in an attempt to rescue you from the dangerously low blood sugar. The hormones do this by prompting your liver to release stored glucose in larger amounts than usual. But this system isnt perfect in a person with diabetes, so the liver releases more sugar than needed which leads to a high blood sugar level in the morning. This is the Somogyi effect.

Late Dinner Or Bedtime Snack With Carbs

Carbohydrates raise blood glucose levels. A high amount of carbohydrates, especially eaten late at night, can lead to morning hyperglycemia. Carbohydrates are in bread, pasta, rice, potatoes, sweets, fruit, and many other foods, as Harvard School of Public Health explains. Having multiple servings at a meal or late-night snack can lead to sustained high blood glucose through the night and into the morning, especially if digestion is slow.

High blood sugar may be linked to a late dinner or a bedtime snack with carbs if you check your blood sugar between 2 and 3 a.m. for a few nights and it is within range, but a little higher than normal, or if it is high and out of range.

Baby Carrots Cherry Tomatoes Or Cucumber Slices

Non-starchy vegetables are a great choice for a snack. They are very low in calories, fats, and carbohydrates, while offering plenty of vitamins and minerals.

These vegetables also provide antioxidants and a good dose of fiber to boost heart and gut health. For more protein, add a low-fat cheese slice to this low-calorie snack.

Test Oatmeal Before It Hits The Trash

But.. before you toss that box of oats into the garbage can, you can try these tips to see if your blood sugar responds any better.

First, make sure you are not adding additional carbs to your oatmeal such as milk, honey, sugar, or dried fruit.

For extra flavor, try adding low carb additions like chia seeds or chopped walnuts instead. If you need some sweetness, you can add some stevia.

Next, keep the portion size in check. Ideally, you want to only consume about a half-cup serving cooked.

Lastly, the type of oats can make a difference so make sure you are choosing whole oats over instant. A packet of instant oatmeal has a higher glycemic index compared to the same amount of steel-cut oats. This may impact your blood sugar response.

Continue to check your blood sugars after consuming oatmeal to see your response and if the above adjustments make any difference. If blood sugar is rising , this is not a good food for you and youre better off eating a lower-carb breakfast.

How To Stabilize High Blood Sugar At Night

Why Does My Blood Sugar Go Up When I Don

When your blood sugar rises at night, there are different actions you can take to tackle the causes and effects.

Drink enough

The symptom of increased urination is the bodys natural reaction to get rid of the excess amount of sugar in the blood. It is therefore important to drink enough to stimulate this process.


It is very important to not do any exercise while your blood glucose level is too high . Instead it is advised to measure your ketones and have a low intensity work out or postpone exercise, depending on your measurements. This is recommended because there may not be enough insulin available to lower the blood glucose that is released during exercise. This can cause more frequent urination that can lead to dehydration. Especially when you lose more water from sweating and breathing during exercise. Furthermore, if the body is forced to burn fat for fuel, as is the case when insulin levels are too low, this can lead to diabetic ketoacidosis. Read on to learn more about this condition.

Dont overeat

Your blood sugar spike at night might be caused by eating too much food at dinnertime compared to the amount of insulin you inject in your body. When you do feel like a snack, consider measuring your blood glucose to see if it should be a snack with a high or low amount of carbohydrates. Read more about this in our food and diabetes guide.

    The best option is to use a continuous glucose monitoring system . This will give you an entire nights worth of blood sugar values, making it easy to identify what direction your blood sugar moved while you slept.

    Treating High Morning Blood Sugar

    A blood sugar high in the morning “can be tough to treat, acknowledges Amori, but with the help of your medical team, you can try different approaches. Talk with your doctor about these strategies:

    Adjust your pump. If youre testing high regularly and you use an insulin pump, you might be able to program it to help manage your morning highs.

    Check blood sugar before bed. Granted, many people have morning high blood sugar after an acceptable blood sugar before bedtime. Even so, “don’t go to bed with high blood sugar,” cautions Amori.

    Take basal insulin. Taking basal insulin at bedtime could help, but be sure to clear any changes in dosing with your physician before you try it.

    Adjust medication. If in fact your high morning blood sugar is a rebound response to a low blood sugar level while youre asleep, you might need to change the dose of any medication you take in the evening that could be causing low blood sugar. Talk with your doctor about whether your medication schedule should be adjusted to treat morning highs.

    Have a healthy pre-bed snack. For those experiencing the Somogyi effect, a healthy mixed snack of protein and carbohydrates could help prevent your blood sugar roller coaster at night. Amori advises working with a registered dietitian if youre not sure how to fit a pre-bed snack into your daily diet.
