What Is The Somogyi Effect

Intermittent Fasting & Hypoglycaemia: Fasting With Low Blood Sugar? | Dr. Nick Z.

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.

Reduce Your Stress Levels Through Meditation

If you find your stress levels are high on a morning, you need to find a way to handle them. Stress is bad for you overall. Its known as a silent killer, as it raises your blood pressure and has no symptoms at all until you start to suffer from health problems seriously.

While exercise is a good way to reduce your stress levels, its not the only option. Nor is it the perfect option.

Meditation is a powerful way to keep your stress levels to a minimum. You can take in deep breaths, allowing your body to get all the oxygen it needs. Your mind focuses elsewhere, helping to release the tension and problems that are affecting your current levels of cortisol.

As your body can release more happy hormones, your stress hormones are suppressed. You can use breathing and meditation techniques regularly to keep your hormone levels balanced. Not only will you improve your morning glucose levels but youll find your overall health benefits considerably.

Normal Blood Sugar Levels After Eating For Diabetics

The American Diabetes Association recommends that the blood sugar 1 to 2 hours after the beginning of a meal be less than 180 mg/dl for most nonpregnant adults with diabetes. This is typically the peak, or highest, blood sugar level in someone with diabetes. Again, this target may need to be individualized for certain people based on such factors as duration of diabetes, age and life expectancy, cognitive status, other health conditions, cardiovascular complications, and hypoglycemia unawareness. Its important that people with diabetes discuss their target blood sugar goals with their healthcare provider.

If you have gestational diabetes or are at risk for developing it, your doctor will monitor your blood sugar.

Other Ways To Measure Blood Sugar

Why Is Blood Sugar High In The Morning?

Checking your blood sugar levels with a glucometer is not the only way to measure blood sugar. Other tests that your healthcare provider might use to check your blood sugar levels are hemoglobin A1c and oral glucose tolerance test . If youre really lucky, you may have access to a continuous glucose monitor .

HbA1c provides an estimate of your average blood sugar levels over time, giving you a sense of your blood sugar control over the last two or three months. An HbA1c test is the most common measurement used for diagnosing type 2 diabetes.16

However, HbA1c tests and blood sugar tests dont always agree. Using HbA1c levels to diagnose diabetes often fails to identify individuals who would otherwise be diagnosed with diabetes using blood sugar levels.17

Your HbA1c is normal if it is below 5.7%. You may have prediabetes if your HbA1c is above 5.7% but less than 6.5%. You may have diabetes is your HbA1c is 6.5% or over.

6.5% or higher
Cautious approach Less than 5.4 %

To learn more about HbA1c measurements and how they relate to blood sugar levels you record with your glucometer, see our full guide to understanding HbA1c.

An oral glucose tolerance test can be more accurate in terms of diagnosing prediabetes or diabetes.18 It measures your blood sugar two hours after you drink 75 grams of glucose. Because it requires drinking a large sugar solution, an OGTT may not be a useful test for someone on a long-term low-carb or ketogenic diet .

    Getting professional medical advice from a healthcare provider like an endocrinologist is the best way to learn more about whether your blood sugar levels are where they should be. Not getting proper treatment for low or high blood sugar levels can be serious and lead to health complications, especially for those with diabetes. Diabetes complications include nerve damage, kidney disease, heart disease, or heart attacks.

    If you see a healthcare provider about your blood sugar levels, be prepared to answer questions about risk factors like what you eat, how much you exercise, and about your family history. Some healthcare providers may want to take a blood sample to test your blood sugar levels. They may also order an A1C test, which is a blood test that measures blood sugar levels over several months. You may have to fast eight hours beforehand to get accurate test results, so its always a good idea to check before your appointment.

    If your blood sugar level goes above 250 mg/dL, you should go to the ER for immediate medical attention, says Dr. Tarugu. Emergency rooms are equipped to handle high blood sugar levels and can administer treatments like insulin therapy and fluid or electrolyte replacement.

    What Happens To Your Blood Sugar When You Fast

    25 Printable Blood Sugar Charts [Normal, High, Low] á? ...

    Lets get rid of the elephant in the room: fasting causes hypoglycemia. As in low blood sugar. When you fast, your body needs to transition from using glucose for energy to using ketones.

    Your cells have to adapt to running on ketones for energy and not glucose. This state is called ketosis and it can come along with what is commonly called keto flu.

    Keto flu includes lightheadedness and headaches. These are two known symptoms of hypoglycemia. Which is logical, since hypoglycemia = low blood sugar. This state will have an impact on your brain first since it runs entirely on glucose, which will be the cause of these symptoms.

    But this type of hypoglycemia, if youre not diabetic, is not a threat to your health. This keto flu is common, but it can be pretty heavy if youre not used to fasting.

    If youre experiencing these symptoms and youre not sure its caused by the fast, simply try and eat some proteins. This should reduce the effect of keto flu drastically. But eating is actually a temporary fix to this problem.

    What you could do to prevent this state is simply to gradually adapt your body to ketosis. Instead of doing, for example, a 24 hour fast, start with 16, or 12. The idea is to get your body used to fast.

    Lightheadedness can also come from low electrolytes, meaning low potassium and sodium levels. As your sodium levels decrease, the body tends to lower blood volume, which can add to the low blood sugar.

Then our liver secrets some stored glucose in our blood vessels which will move into body cells with the help of insulin. So, in a fasting blood sugar test if your blood sugar level is more than normal that means your body lacks insulin and you may have diabetes.

    Fasting Vs Nonfasting Blood Sugar

    Fatigue & Low Blood Sugar While Fasting

    Fasting blood sugar is a test that measures blood sugar and is used to determine if an individual has diabetes. When a person takes this test, they are not to eat or drink for at least eight hours prior to the test. The results determine whether or not a person is prediabetic or diabetic.

    The results are measured in milligrams per deciliter or mg/dL. The following results indicate whether or not a person is prediabetic or diabetic:

    • Normal: Less than 100 mg/dL
    • Prediabetes: 100 mg/dL to 125 mg/dL
    • Diabetes: 126 mg/dL or higher

    To test nonfasting blood sugar, an A1C test is administered to determine the average blood sugar level of an individual over a period of two to three months. There is no need to fast prior to taking this test. The following results indicate whether or not a person is prediabetic or diabetic:

    • Normal: 5.7%
