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.
What Is Normal Blood Sugar
ByElizabeth Palermopublished 31 March 14
Blood sugar, or glucose, is an important source of energy and provides nutrients to your body’s organs, muscles and nervous system. The body gets glucose from the food you eat, and the absorption, storage and production of glucose is regulated constantly by complex processes involving the small intestine, liver and pancreas.
Normal blood sugar varies from person to person, but a normal range for fasting blood sugar is between 70 and 100 milligrams per deciliter. For most individuals, the level of glucose in the blood rises after meals. A normal blood-sugar range after eating is between 135 and 140 milligrams per deciliter.
These variations in blood-sugar levels, both before and after meals, are normal and reflect the way that glucose is absorbed and stored in the body. After you eat, your body breaks down the carbohydrates in food into smaller parts, including glucose, which can be absorbed by the small intestine.
As the small intestine absorbs glucose, the pancreas releases insulin, which stimulates body tissues and causes them to absorb this glucose and metabolize it . This stored glucose is used to maintain healthy blood-sugar levels between meals.
When there isn’t enough glucose stored up to maintain normal blood-sugar levels, the body will even produce its own glucose from noncarbohydrate sources . This process, known as gluconeogenesis, occurs most often during intense exercise and instances of starvation.
Does High Blood Sugar Make You Sleepy
Surprisingly, one of the symptoms of diabetes or pre-diabetes is excessive sleepiness. But the cause of it is probably different than youd guess.
Youd think that a high blood sugar would create a sugar rush, which would give you a boost of energy. Right?
That is true initially especially if youre healthy and you dont have insulin problems. But if you arent, then things are different for you.

Take A Correction Dose
For those who take fast or rapid-acting insulin Novolog, Humalog, Apidra, Fiasp, Admelog, Afrezza you can take a correction dose to bring a high blood sugar down.
A correction factor is determined with support from your healthcare team. This number tells you how much 1 unit of fast or rapid-acting insulin will lower your blood sugar. For example, a correction factor of 1:50 means that 1 unit of insulin will lower your blood sugar by 50 points.
Its important to keep in mind how much insulin you may already have on board in your bloodstream before taking an additional dose of insulin.
Most fast and rapid-acting insulin stays in your system for approximately 3 to 4 hours, which means taking an additional dose of insulin to correct a high could lead to a severe low blood sugar if you already have a significant amount of insulin from your most recent dose still in your bloodstream.
Also, remember to give that correction dose of insulin at least two hours to make an impact on your blood sugar before getting frustrated and taking another injection. You wont see a significant improvement in your blood sugar until its been in your system for at least 2 to 3 hours .
Is It Safe To Sleep With High Blood Sugar
Glucose levels that are occasionally a little high at night generally dont pose serious, immediate health concerns. Most people with diabetes cannot avoid some high glucose levels. However, frequent or long-term highs particularly extremely high levels can be dangerous. It is important for people with diabetes to reduce high blood sugar as much as possible for two key reasons:
Frequent hyperglycemia can lead to major health complications caused by damage to blood vessels and nerves, which can affect your eyes, heart, kidneys, and other organs. This occurs when glucose levels are too high over a long period of time.
Very high glucose levels can be a sign of diabetic ketoacidosis . This occurs mainly in people with type 1 diabetes and can be life-threatening. For more information on DKA, read Ketosis vs. Ketoacidosis: Whats the Difference.

Nerve damage, nerve pain and numbness or tingling in the extremities Individuals with diabetes are not able to convert blood sugar into energy either because on insufficient levels of insulin or because their insulin is simply not functioning correctly. This means that glucose stays in the bloodstream, resulting in high blood sugar levels. Diabetes takes two distinct forms: Type 1 and type 2. Diagnosing hyperglycemia is done by assessing symptoms and performing a simple blood glucose test. Depending on the severity of the condition and which type of diabetes the patient is diagnosed with, insulin and a variety of medication may be prescribed to help the person keep their blood sugar under control. Insulin comes in short, long and fast-acting forms, and a person suffering from type 1 diabetes is likely to be prescribed some combination of these. Individuals who are either diagnosed with type 2 diabetes or are considered at risk for the disease are recommended to make alterations to their diet, lifestyle habits and exercise routine in order to lower blood sugar and keep it under control. These changes generally help to improve blood glucose control, individuals with type 2 diabetes may require medication eventually. These can include glitazones, acarbose, glucophage or sulphonylureas.Continue reading > >

Fasting Blood Glucose Level Test Preparation
What should you do if your doctor orders a fasting blood sugar test? The preparation is the same as when you take a fasting test for cholesterol. First, be sure to find out if you need to schedule an appointment for your test . Ask your doctor what time is best to take it.
- Schedule your test if necessary
- Ask your doctor if you need to change any of the medications you take on the morning of the test

What Should My Blood Sugar Level Be
When you’re first diagnosed with diabetes, your diabetes care team will usually tell you what your blood sugar level is and what you should aim to get it down to.
You may be advised to use a testing device to monitor your blood sugar level regularly at home.
Or you may have an appointment with a nurse or doctor every few months to see what your average blood sugar level is. This is known as your HbA1c level.
Target blood sugar levels differ for everyone, but generally speaking:
- if you monitor yourself at home with a self-testing kit a normal target is 4 to 7mmol/l before eating and under 8.5 to 9mmol/l 2 hours after a meal
- if your HbA1c level is tested every few months a normal HbA1c target is below 48mmol/mol

How To Stabilize Your Blood Sugar Overnight
The most important thing you can do to stabilize your blood sugar is monitor your glucose levels at bedtime, during the night, and when you wake up to look for patterns. This will help you determine whats going on in your body and how you can fix it. While there are many strategies people use to stabilize blood sugar at night, every person is different youll have to look for trends in your body, experiment with ways to lower glucose levels over a period of time, and learn what works best for your body.
Check your blood sugar before bed. If its already high, your blood sugar levels may remain high throughout the night. To address this, youll want to start by adjusting when you eat your evening meal and what it consists of, and how much mealtime insulin you take to cover it.
Avoid eating lots of food close to bedtime. For diaTribe writer Adam Brown, the key to staying in range overnight is low-carb, early dinners, with no snacking after dinner.
Consider eating less food at night and taking more basal insulin to cover your evening meal.
Check your blood sugar during the night, between midnight and 3am. If you were in range before bed but have high glucose levels between midnight and 3am, you may need to adjust your basal insulin dosage and timing. If you are low during that time, you may experience a rebound high blood sugar later on this is usually associated with overcorrecting the low.
Blood Sugar Levels During Pregnancy
The NIDDK states that gestational diabetes is high blood sugar that occurs during pregnancy if you were not diabetic before getting pregnant. Healthy blood sugar during pregnancy can help lower your risk of developing type 2 diabetes later. It can also lower the risk of your baby being born prematurely, at a high birth weight, and having respiratory problems.
Blood sugar and insulin levels during the first trimester of pregnancy tend to be lower than usual, but they rise during the late second and early third trimesters. You can be diagnosed with an oral glucose tolerance test .
These are the steps for the 2-step strategy.
- Drink a solution with 50 grams of glucose about the amount in 1 16-oz. bottle of a soft drink
- Get your blood drawn after 1 hour. IF the value is high, retest
- Fast overnight
- Drink a solution with 100 grams of glucose about the amount in 12 peanut butter cups
- Get your blood drawn immediately and after 1, 2, and 3 hours
Or, your doctor might use the 1-step strategy with a 2-hour OGTT:
- Fast overnight
- Drink a solution with 75 grams of glucose
- Get your blood drawn immediately and after 1 and 2 hours
These are some values to know from NIDKK related to gestational diabetes and healthy blood sugar in pregnancy.

How Can High Blood Sugar Levels In The Morning Be Controlled
Once you and your doctor determine how your blood sugar levels are behaving at night, he or she can advise you about the changes you need to make to better control them. Options that your doctor may discuss depend on the cause of the morning high blood sugars.
For dawn phenomenon:
- Changing the timing or type of your diabetes medications
- Eating a lighter breakfast
- Increasing your morning dose of diabetes medication
- If you take insulin, switching to an insulin pump and programming it to release additional insulin in the morning

Recommended Blood Sugar Targets
For people with type 1 diabetes, the American Diabetes Association recommends that blood sugar targets be based on a person’s needs and goals. Talk to your doctor and diabetes educator about these goals. A general guideline is:
Before meals, your blood sugar should be:
- From 90 to 130 mg/dL for adults
- From 90 to 130 mg/dL for children, 13 to 19 years old
- From 90 to 180 mg/dL for children, 6 to 12 years old
- From 100 to 180 mg/dL for children under 6 years old
After meals , your blood sugar should be:
- Less than 180 mg/dL for adults
At bedtime, your blood sugar should be:
- From 90 to 150 mg/dL for adults
- From 90 to 150 mg/dL for children, 13 to 19 years old
- From 100 to 180 mg/dL for children, 6 to 12 years old
- From 110 to 200 mg/dL for children under 6 years old
For people with type 2 diabetes, the American Diabetes Association also recommends that blood sugar targets be individualized. Talk to your doctor and diabetes educator about your goals.
In general, before meals, your blood sugar should be:
- From 70 to 130 mg/dL for adults
After meals , your blood sugar should be:
- Less than 180 mg/dL for adults
What Are The Symptoms Of High Blood Sugar
Whenever the glucose level in ones blood rises high temporarily, this condition is known as hyperglycemia. The opposite condition, low blood sugar, is called hypoglycemia.
Glucose comes from most foods, and the body uses other chemicals to create glucose in the liver and muscles. The blood carries glucose to all the cells in the body. To carry glucose into the cells as an energy supply, cells need help from insulin. Insulin is a hormone made by the pancreas, an organ near the stomach.
The pancreas releases insulin into the blood, based upon the blood sugar level. Insulin helps move glucose from digested food enter into cells. Sometimes, the body stops making insulin , or the insulin does not work properly . In diabetic patients, glucose does not enter the cells sufficiently, thus staying in the blood and creating high blood sugar levels.
Blood sugar levels can be measured in seconds by using a blood glucose meter, also known as a glucometer. A tiny drop of blood from the finger or forearm is placed on a test strip and inserted into the glucometer. The blood sugar level is displayed digitally within seconds.
High blood sugar level fluctations occur daily in people with diabetes. It is important to control blood sugar levels through diet, exercise, and medication , to know the symptoms of elevated blood sugar, and to seek treatment, when necessary.
Are You Suffering From Untreated Hyperglycemia
Untreated hyperglycemia leads to serious complications. Signs are hard to identify, but self-monitoring and early treatment lowers these risks and improves quality of life.
Hyperglycemia, or high blood sugar, affects people who have diabetes. Since the symptoms are difficult to feel and easily go unnoticed, the condition often goes untreated. Prolonged hyperglycemia is the main cause of almost all the complications associated with diabetes but good blood sugar control can prevent them. The more you know about high blood sugar, the more likely you are to recognize it, treat it, and hopefully take steps to prevent it.

What Is The Dawn Phenomenon
Another reason for high nighttime blood sugar levels is the dawn phenomenon. The dawn phenomenon occurs early in the morning when the body naturally signals your liver to produce glucose, giving your body the energy it needs to wake up.
The hormonal changes associated with the dawn phenomenon happen to people with or without diabetes, though those without diabetes do not experience hyperglycemia. If you take insulin, you may need to try a new basal insulin or adjust the timing and amount of your basal dose or your nighttime basal rates to cover an early morning rise.
