Trying to learn how to lower morning blood sugar? Heres why your glucose levels rise in the morning and a few things you can try to keep them in range.

Waking up with high glucose levels may feel like it doesn’t make sense. You spend several hours asleep, not consuming any carbs, and yet somehow your glucose levels are still high when you wake up in the morning.

Why does this happen? What can you do to make sure your glucose levels are safely in range in the morning? Learn more about some tips on avoiding high morning blood sugar levels so you can start your day off right.

Factors That Can Affect Blood Sugar Levels

If you have prediabetes or diabetes, you may have insulin resistance or an inability to produce insulin. This means your body has difficulty regulating blood sugar levels on its own.

Its a delicate balance to maintain, so the following list can help you familiarize yourself with factors that can cause your blood glucose levels to go up or down.

Should You Get Screened For Type 2 Diabetes

If someone in your family has had type 2 diabetes, your chances of developing it rise. Patients with a first-degree relative mother, father, sibling with type 2 diabetes have a two to threefold risk of developing it, says Sarah Rettinger, MD, an endocrinologist at Providence Saint Joseph Health in Santa Monica, California.

Blood Sugar Level After 2 Hours:

Another crucial time to check blood glucose level is about an hour and a half after a meal. Generally, around this time the process of digestion and absorption is near its end. So, high blood sugar during this time generally means that the body cant process sugar properly.

In case of a normal individual, blood glucose level at this time is below 7.8 mmol/L. If the sugar level is 11.1 mmol/L or more, then the individual is considered to be diabetic.

Why Doctors Order It

Study ties higher blood sugar to dementia risk

A fasting blood glucose test is done to screen for prediabetes and diabetes. It also helps doctors monitor diabetes and determine if medications and dietary changes are having an effect .

Your fasting blood glucose level is the lowest your blood sugar can be because the influence of recent meals is minimized .

Fasting blood sugar is often checked alongside HbA1c , which is a measure of your blood sugar levels over the past three months. The more sugar there is in the blood, the more it will attach to hemoglobin, raising HbA1c .

Taken together, the two offer more information than each test alone. For example, even if your blood sugar levels are very high at one random point, they may have been mostly low over the past couple of months . On the other hand, HBA1c could be higher but your glucose levels at the moment lower.

Apart from diabetes, abnormal levels can point out issues such as insulin resistance, hormonal imbalances, and pancreatic, liver, or kidney disease.

Causes Related To Personal Health

Insulin resistance

This condition occurs when the cells in your muscles, fat, and liver are unable to use the glucose in your bloodstream for energy. Your pancreas responds to this increase in glucose by producing more insulin to help your body process it. This excess amount of insulin in the bloodstream can eventually cause your body to lose insulin sensitivity or build resistance to it, leading to higher blood glucose levels.

Bodyweight and body fat

Research connects being overweight and having a higher body fat percentage with high blood glucose levels. In fact, a high body fat percentage might be a clearer indicator of high blood sugar and diabetes than weight or body mass index .

Other health conditions

Certain conditions could make you more likely to have high blood glucose. These include Cushingâs disease, polycystic ovarian syndrome , and gestational diabetes. Blood glucose may also rise as the result of common illnesses like a head cold or the flu.

Hormonal changes

It isnât just stress and sleep that can cause fluctuations in hormones. Illness, physical pain and trauma, menopause or menstruation can as well. In any of these instances, your blood glucose levels may rise due to the changes in your hormone levels.

Medications

Gut issues

A growingbody of research links imbalances in the microbiota living in our guts to an inability to regulate glucose levels in the blood. This is sometimes due to antibiotic use or infection.

What Are The Symptoms Of High Blood Sugar

The symptoms of high blood sugar can vary depending on severity.

Early signs and symptoms of high blood sugar

When your blood sugar is around 200 mg/dL, but not yet dangerously high, you may experience the following symptoms:

  • Increased thirst
  • Shortness of breath
  • Coma

If you are experiencing any of the later-stage symptoms of high blood sugar, seek immediate medical attention.

What Is Considered Low Blood Sugar

For the average person with diabetes, low blood sugar means anything under 80 mg/dL .

Very low blood sugars are any readings under 40 mg/dL. Anything under 40 mg/dL is considered extremely dangerous and potentially fatal.

A person is at a significantly higher risk of falling into a diabetic coma if they cannot get their blood sugar above 40 mg/dL for several hours.

If a person is experiencing a severe low, and they are unable to chew food or swallow liquids, they will require an emergency shot of Glucagon .

A complex array of factors affects blood sugar levels, including hormones, diet, and lifestyle.

Q: I have prediabetes and now eat minimal carbs and sugar. My doctor told me to monitor my sugar levels, morning and night. At night, two hours after eating, my sugar levels are between 112 and 130 mg/dL . But in the morning, my fasting sugar level is always higher than the night number. Why is that? What am I doing wrong?

There are a few reasons why your blood sugar may be elevated in the morning. First, its important to understand that certain hormonal changes that occur overnight may lead to high blood sugar levels in the morning.

Do I Need To Check My Blood Sugar Level

Your healthcare provider will tell you if you need to check your blood sugar level. He or she will also tell you how often to check it. Ask your healthcare provider what your blood sugar level should be. Write down your results, and show them to your healthcare provider. Your provider may use the results to make changes to your medicine, food, and exercise plan.

High blood sugar, also called hyperglycemia, occurs when there is too much glucose in the blood. High blood sugar is the , but it can also occur in people who dont have type 1 or type 2 diabetes, either because of stress or trauma, or gradually as a result of certain chronic conditions.

It is important to manage high blood sugar, even if you dont have diabetes, because elevated blood glucose can delay your ability to heal, increase your risk of infections, and cause irreversible damage to your nerves, blood vessels, and organs, such as your eyes and kidneys. Blood vessel damage from high blood sugar also increases your risk of heart attack and stroke.

What Is Blood Sugar

Blood sugar, or blood glucose, is a measurement of the amount of glucose in your blood.

When you eat carbohydrates, your body breaks down those carbs into glucose. This becomes your body’s main source of energy, and fuels the vital functions in your brain, heart, liver, and muscles, says Nestoras Mathioudakis, MD, a diabetes expert at Johns Hopkins Medicine.

For people without diabetes, the pancreas releases insulin to help your cells absorb glucose and fuel your body. But for people with diabetes, the body does not produce insulin or it doesn’t work properly, and as a result, blood sugar levels must be carefully regulated to prevent health complications.

Techniques To Manage Your Blood Sugar In The Morning

Based on your glucose levels and trends, there are a few things you can do to manage your glucose levels so they dont run high in the morning. Some of these strategies focus on adjusting medications to better suit your needs. Other strategies include adjusting your exercise routine, as well as what and when you are eating before bed.

  • If your glucose levels are in range before bed, they may rise throughout the night without enough insulin. This can be especially true for people who take long-acting insulin in the morning, since it may be wearing off before your next dose.

  • Consider changing the time of day when you take your long-acting insulin. You may also benefit from switching to either twice-daily basal insulin or ultra-long-acting insulin, or from starting on an insulin pump. Read our article, Are You on the Right Kind of Insulin, to learn more.

  • Check your blood glucose during the night between 3 am and 8 am. If you are running high during these hours, you may be experiencing the dawn phenomenon.

  • Talk with your healthcare team about finding the best nighttime insulin regimen for you. If you take basal insulin, you may need to delay the timing of your dose to as close to bedtime as possible. Another option is to try an insulin pump or automated insulin delivery system. AID systems will automatically adjust your basal insulin doses throughout the night to help keep your glucose levels stable.

  • Oral Glucose Tolerance Test

    The oral glucose tolerance test takes a little more time than the other two glucose tests for diabetes. In this test, your blood is taken after an overnight fast, and then again two hours after you drink a sugary drink.

    Its normal for blood sugar to rise after the drink. Normal blood sugar falls to below 140 mg/dL within two hours, however.

    If your blood sugar is between 140 and 199 mg/dL, your doctor will diagnose prediabetes. Anything 200 mg/dL or above is diagnostic for type 2 diabetes.

    Type of results

    You should have healthy fats each day as well.

    Using the information from your food log, you can begin to make small changes. The goal is to choose less processed, whole foods, instead of highly processed foods that contain added sugar, little fiber, and unhealthy fats.

    For example, if you arent eating the recommended servings of vegetables, try adding one serving of vegetables a day to your diet.

    You can do this by having a salad with lunch or dinner, or snacking on carrot sticks. Just be careful about add-ons such as salad dressing or dips. They can sneak in unhealthy fats or extra calories. Check out these 10 healthy salad dressing recipes.

    Youll also want to work on reducing the number of empty-calorie foods and beverages youre consuming, as well as switching out simple carbohydrate foods for complex carbohydrates. Examples of substitutions you can try to include:

    Signs Of High Blood Sugar In The Morning

    High blood sugar is significant when its too high. Thats when its called hyperglycemia. Hyperglycemia is usually defined as above 126 mg/dL or 7.0 mmol/L in a period of fasting . This will be the clearest sign of high blood sugar in the morning.

    Before breakfast, you usually would have had a period of at least eight hours without eating . As such, hyperglycemia during a period of fasting is particularly important here: youll know that the high blood sugar wasnt caused by any recent meals.

    Other signs of high blood sugar in the morning will be the usual symptoms of hyperglycemia:

    • Nausea
    • Blurred vision
    • Increased urination

    Of course, its normal to feel somewhat groggy and thirsty when waking. Its important to distinguish between hyperglycemia and the I-hate-Mondays morning tiredness. And the best way to do that is to test your blood sugar.

    What Are Normal Blood Sugar Levels

    You might want to measure your blood sugar before meals to get a baseline, and then two hours after your meal to measure your normal blood sugar level. Your doctor might also suggest measuring blood sugar before bed to be sure you have been eating well throughout the day and can go to sleep with peace of mind.

    These are considered within the range of normal for blood sugar:

    • Less than 140 mg/dl if you do not have diabetes.
    • Less than 180 mg/dl if you have diabetes.

    What Do The Results Mean

    Doctors measure the amount of glucose in a persons blood in milligrams per deciliter .

    For a random glucose test, a result of 200 mg/dl or above indicates that a person may have diabetes. However, the doctor will usually repeat the test on another day for a more reliable diagnosis.

    To help confirm the diagnosis, the doctor may also order a different type of test, such as a fasting glucose test or an OGTT.

    Results of a fasting glucose test indicate the following:

    • Normal: less than 100 mg/dl
    • Prediabetes: 100125 mg/dl
    • Diabetes: 126 mg/dl or above

    Results of an OGTT

    • Diabetes: 200 mg/dl or above

    One 2015 study suggests that one random glucose test with a reading of over 100 mg/dl is a greater risk factor for diabetes than traditional factors, such as obesity.

    Prediabetes means that a persons blood glucose levels are higher than usual, but doctors do not yet consider that they have diabetes. Doctors sometimes call this impaired glucose tolerance or impaired fasting glucose .

    People with prediabetes are at increased risk of developing diabetes. Lifestyle modifications, such as weight loss and exercise, and certain medications can help reduce this risk.

    Causes Of Blood Sugar Levels

    Why are my Morning Fasting Blood Sugar Levels high?

    Whilst the liver and muscles produce some glucose, most comes from the foods we eat. Food and drinks that are high in carbohydrates are most impactful on blood sugar level. What we eat provides us most of the nutrients our body needs and sometimes, does not need. That is not to say that food is a major cause of blood sugar level increasing or decreasing too dramatically.

    Typically, if a person has health conditions or poor nutrition, this will lead to a spike or decline in blood sugar level. The causes differ from high to low blood sugar levels and are as follows:

    Understand Nutrition And Adjust Your Diet

    What you choose to eat and drink can have a major impact on not only your waistline, mood, and well-being, but also on your blood sugar levels.

    All macronutrients can affect your blood sugar to some degree so developing a good understanding of how they affect your blood sugar will enable you to be proactive and prevent blood sugar swings.

    Carbohydrates

    Carbohydrates have the greatest impact on your blood sugar, which is why many people with diabetes can benefit from following a low- to medium-carb diet . The fewer carbs you eat, the less insulin you need to take, which makes diabetes management easier.

    However, you dont have to follow a low-carb diet if it doesnt work for you physically or mentally. As I wrote in my post about which diet is best for people with diabetes, it is very possible to have great blood sugar control on a medium carb diet, as long as you experiment, take notes, and learn to take the right amounts of insulin for the carbs you are eating.

    It is very important to realize that we all react differently to carbs so you have to find the diet and foods that are right for you.

    As an example, people react very differently to carbs like oats or sweet potato. Some people can eat oats with only a small increase in blood sugar while others see a quick spike. By simply knowing this, people struggling with a certain type of carb can choose to reduce their consumption or cut it out of their diet altogether.

    What Is Normal Blood Sugar

    Morning Fasting Blood Sugar 136

    What constitutes normal blood glucose varies for an individual depending on a range of factors.

    Blood sugar, or glucose, is a form of sugar that serves as the body’s main source of energy. We obtain glucose from the food we eat, predominantly carbohydrate-rich foods such as potatoes, rice and bread. The absorption and storage of glucose is regulated constantly by complex processes that take place in our digestive systems.

    What constitutes normal blood glucose varies for an individual depending on a range of factors, including age, any underlying medical conditions, and the medications they take and depends on when they consumed their last meal.
