Target Blood Sugar Ranges For Pregnant People With Diabetes

What should my blood sugar level be on average?

Blood sugar targets during pregnancy are lower due to hormonal influences. The ADA, AACE, and Joslin Diabetes Center have slightly different guidelines for target blood sugar levels during pregnancy. In general, pregnant women with diabetes will want to follow individual guidelines provided by their endocrinologist.

The ADA recommends maintaining blood sugar levels of 95-140 mg/dL for pregnant women. However, some providers recommend an even tighter goal of blood glucose levels below 89 mg/dL before a meal and below 120 mg/dL after a meal.

To keep close tabs on levels, most diabetes specialists recommend that women with diabetes during pregnancy check their blood sugar:

  • First thing in the morning
  • Before all meals

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.

Diabetes Is Diagnosed By Any One Of The Following:

  • Two consecutive fasting blood glucose tests that are equal to or greater than 126 mg/dL
  • Any random blood glucose that is greater than 200 mg/dL
  • An A1c test that is equal to or greater than 6.5 percent. A1c is an easy blood test that gives a three month average of blood sugars
  • A two-hour oral glucose tolerance test with any value over 200 mg/dL
  • Sometimes you may have symptoms of fatigue, excessive urination or thirst, or unplanned weight loss. However, often people have no symptoms of high blood glucose and find a diabetes diagnosis surprising.

    High Blood Sugar In The Morning: Is It The Dawn Phenomenon

    If you have high blood sugar levels in the morning, you may be experiencing the dawn phenomenon, the name given to an increase in blood sugar that usually occurs between 2 a.m. and 8 a.m., according to the Mayo Clinic. One reason this occurs: During the early hours of the morning, our bodies secrete higher levels of a hormone called cortisol, says Dr. Spratt. When cortisol levels are high, it can make you more resistant to insulin, a hormone that helps regulate your blood sugar levels.

    “Some people have a striking dawn phenomenon,” says Dr. Spratt. “You can look at their continuous glucose tracing and see that their blood sugar level suddenly goes up at 3 a.m.” If this is the case for you, your doctor may adjust your insulin medication or suggest you use an insulin pump .

    How To Treat Low Blood Sugar

    Avoiding imbalance of sugar levels

    If you think you have low blood sugar, be sure to check it.

    Keeping your blood sugar levels on target as much as possible can help prevent or delay long-term, serious health problems. While this is important, closely managing your blood sugar levels also increases your chance for low blood sugar . Blood sugar below 70 mg/dL is considered low. If you think you have low blood sugar, check it. If you arent able to check it, go ahead and treat it.

    Untreated low blood sugar can be dangerous, so its important to know what to do about it and to treat it immediately.

    How Do I Measure Blood Sugar

    If you have diabetes, you probably already keep a watchful eye on your blood sugar through the use of a continuous glucose monitor or a blood sugar meter . Blood sugar measurement is also typically included in routine lab work for people without diabetes — your physician will usually order a glycated hemoglobin test, which measures your average blood sugar over the past two to three months.

    Say your A1C test comes back with no sign of diabetes — constantly measuring your blood sugar can still be helpful. For instance, some people experiment with using a CGM to see how their body responds to different types of food. However, it’s good to note that this is a fairly cost-intensive way of figuring out your nutrition, and writing down a food diary that includes how you felt after each meal will also help you figure out what to eat.

    Check out these blood sugar monitors if you’re looking for recommendations on how to keep track of your levels at home.

    Personalizing Your Diet Based On Blood Sugar Response

    In addition to seeing your healthcare provider, there are steps you can take to reduce your blood sugar levels. If you check your blood sugar after meals and keep track of those measurements, along with the types and amounts of food you ate, you may be able to see which foods are problematic.

    Although an increase in blood sugar is usually due to eating high-carb foods, all carbs are not the same when it comes to raising blood sugar. Because starchy foods digest down to glucose very quickly, some starchy foods may end up having a much greater impact on blood sugar than you might expect.

    For instance, even though a banana tastes sweeter than a baked potato, the potato may actually have a bigger impact on blood sugar.13

    Because high-carb foods have the biggest impact on blood sugar levels, it makes sense to reduce them, no matter what type of diet you follow. The American Diabetes made this point in a 2019 paper on nutrition for people with diabetes.14

    Sometimes making gradual changes can work best. Our guide, Eating better: six steps down carb mountain, can help you lower your carb intake, one step at a time.

    If youve been diagnosed with type 1 or type 2 diabetes, our guide to the best foods for diabetes can help you make choices that may reduce your need for blood sugar control medications.

    If a food or beverage seems to be causing your blood sugar to rise too much, try leaving it out of your diet for a few days to see if you notice a difference.

    Normal Blood Sugar Levels For Adults With Diabetes

    Normally, your pancreas releases insulin when your blood sugar, or âblood glucose,â gets high — after a meal, for example. That signals your body to absorb glucose until levels get back to normal.

    But if you have diabetes, your body doesnât make insulin or doesnât respond to it normally . That can leave your blood sugar too high for too long. Over time, that can damage nerves and blood vessels and lead to heart disease and other problems.

    If you have diabetes, your doctor may ask you to keep track of your blood sugar by testing it at home with a special device called a blood glucose monitor or home blood sugar meter. It takes a small sample of blood, usually from the tip of your finger, and measures the amount of glucose in it.

    Follow your doctorâs instructions about the best way to use your device.

    Your doctor will tell you when and how to test your blood sugar. Each time you do it, log it in a notebook or online tool or in an app. The time of day, recent activity, your last meal, and other things can all affect whether a reading will be of concern to your doctor. So try to log relevant information like:

    • What medication and dosage you took
    • What you ate, when you ate, or whether you were fasting
    • How much, how intense, and what kind of exercise you were doing, if any

    That will help you and your doctor see how your treatment is working.

    Guide To Prediabetes: Symptoms Causes And Treatments

    How to Measure Your Blood Sugar When You Are Fasting? And What It Tells You

    Approximately one in three Americans have prediabetes, according to the CDC. However, the majority of cases go undiagnosed and untreated. Prediabetes is when your blood sugar levels are higher than normal, but not yet high enough to be classified as diabetes. Prediabetes symptoms often go undetected, and without prediabetes treatment, blood vessels and nerves can be damaged. This can lead to heart disease and stroke, and eventually, develop into type 2 diabetes.

    Type 2 diabetes, the next stage after prediabetes, is when your body cannot regulate blood sugar levels correctly because you can no longer produce or properly use the hormone insulin. When your body cannot properly use insulin, its known as insulin resistance. Without the proper use of insulin, blood glucose levels can get dangerously high. This is because insulin is a hormone that helps your cells use and process glucose.

    Blood Sugar Level Chart By Age

    Blood sugar levels tend to rise with age due to an increase in insulin resistance and decrease in insulin sensitivity. In one study by the National Health Institute , each extra decade of age was linked to a 2.7 mg/dl increase in fasting glucose, and a 4.5 mg/dl increase in 2-hour post-prandial glucose levels.

    The Nuances Of Low Glucose

    In a recent study, researchers reviewed the published literature to see if low fasting glucose levels affected healthy peoples long term risks of health problems, like strokes and heart attacks. They found that healthy non-diabetic people who had baseline fasting glucose levels of less than 72 mg/dl had a 56% increase in all-cause mortality compared to people with normal fasting blood glucose levels. Also, the risks for heart attacks and strokes were higher in people with baseline fasting glucose levels less than 72 mg/dl. This result is likely due to the body releasing more epinephrine to counteract the low glucose levels too much epinephrine for too long leads to heart problems. Interestingly, people with low fasting glucose levels of less than 83 mg/dl but higher than 72 mg/dl did not have an increased risk of future heart attacks and strokes.

    While there has been an association between low fasting plasma glucose levels and worse health outcomes, it is not clear whether transient dips in glucose levels during a continuous 24-hour period are unhealthy for nondiabetic individuals. Part of the reason that this is unknown is that continuous glucose monitoring is a relatively new technology and has been studied more extensively in diabetic individuals than in healthy individuals.

    How Accurate Are A1c Tests

    A1C levels rise well before the clinical onset of diabetes, making early diagnosis possible according to the 2017 Standards of Medical Care in Diabetes by the American Diabetes Association . Sometimes, however, in the early stages of diabetes, blood sugar levels are not high enough to show up as problematic. Testing environments, such as temperature in the lab, equipment used, and handling of samples, can affect the results however, this is more common in the fasting plasma glucose and the OGTT than in the A1C. Strict quality controls and advancements in testing have made the A1C test more precise than in the past, according to the NIDDK. Doctors should be aware of laboratories that use an NGSP-certified method of testing for A1C levels. The NIDDK warns that blood samples taken at home or analyzed in a healthcare providers office should not be used for diagnosis.

    There are some health conditions and situations that might skew the results of the test. These include:

    • Anemia
    • Dialysis
    • Blood loss or blood transfusions

    Also, the test can be unreliable for people of African, Mediterranean, or Southeast Asian descent, people with a family member with sickle cell anemia, and those with thalassemia. For those who fall into these groups, a healthcare provider might suggest a different test or a specialized A1C.

    Beyond Normal Goals: Whats An Optimal Glucose Level And Why Does It Matter

    Exact numbers for what is considered optimal glucose levels to strive for while using CGM to achieve your best health are not definitively established this is a question that is individual-specific and should be discussed with your healthcare provider. With that said, research shows that there is an increased risk of health problems as fasting glucose increases, even if it stays within the normal range, making finding your optimal glucose levels all the more important.

    While the International Diabetes Federation and other research studies have shown that a post-meal glucose spike should be less than 140 mg/dL in a nondiabetic individual, this does not determine what value for a post-meal glucose elevation is truly optimal for your health. All that number tells us is that in nondiabetics doing an oral glucose tolerance test, researchers found that these individuals rarely get above a glucose value of 140 mg/dL after meals.

    So, while this number may represent a proposed upper limit of whats normal, it may not indicate what will serve you best from a health perspective. Many people may likely do better at lower post-meal glucose levels. Similarly, while the ADA states that a fasting glucose less than 100 mg/dL is normal, it does not indicate what value is optimal for health.

    The following is a summary of insights from our review of research. You should consult with your doctor before setting any glucose targets or changing dietary and lifestyle habits.

    What Else Can I Do To Help Manage My Blood Sugar Levels

    Eating a healthy diet with plenty of fruit and vegetables, maintaining a healthy weight, and getting regular physical activity can all help. Other tips include:

    • Keep track of your blood sugar levels to see what makes them go up or down.
    • Eat at regular times, and dont skip meals.
    • Choose foods lower in calories, saturated fat, trans fat, sugar, and salt.
    • Track your food, drink, and physical activity.
    • Drink water instead of juice or soda.
    • Limit alcoholic drinks.
    • For a sweet treat, choose fruit.
    • Control your food portions .

    What Is Blood Glucose Anyway

    Blood glucose, or sugar, is sugar that is in your blood . It comes from the food that you eat foods that contain carbohydrate, such as bread, pasta and fruit are the main contributors to blood glucose. The cells in our bodies need glucose for energy and we all need energy to move, think, learn and breathe. The brain, which is the command center, uses about half of all the energy from glucose in the body.

    What Causes Blood Sugar To Be High

    Normal Blood Sugar Readings

    Many things can cause high blood sugar , including being sick, being stressed, eating more than planned, and not giving yourself enough insulin. Over time, high blood sugar can lead to long-term, serious health problems. Symptoms of high blood sugar include:

    • Feeling very tired.
    • Having blurry vision.
    • Needing to urinate more often.

    If you get sick, your blood sugar can be hard to manage. You may not be able to eat or drink as much as usual, which can affect blood sugar levels. If youre ill and your blood sugar is 240 mg/dL or above, use an over-the-counter ketone test kit to check your urine for ketones and call your doctor if your ketones are high. High ketones can be an early sign of diabetic ketoacidosis, which is a medical emergency and needs to be treated immediately.

    Your Blood Sugar Isnt Just Because Of What You Eat

    Mainstream media would have you believe that your blood sugar levels are impacted only by what you eat and how much you exercise, but people with type 1 and type 2 diabetes who test their blood sugars frequently could tell you otherwise.

    Its especially important to keep this mind when looking at your own blood sugars and your goals because there are certain variables and challenges that impact blood sugar levels that you cant always control.

    For example:

    • Menstrual cycles: raises blood sugar and insulin needs
    • Adrenaline rushes from competitive sports, heated arguments, rollercoaster rides: raises blood sugar and insulin needs
    • The common cold and other illnesses: usually raises blood sugar and insulin needs
    • Hormonal changes due to puberty and healthy growth in young adults: raises blood sugar and insulin needs
    • An injury which raises overall inflammation levels: raises blood sugar and insulin needs
    • Glucogenesis during anaerobic exercise: raises blood sugar

    While you cant necessarily prevent these factors that affect your blood sugar from occurring, you can work with your diabetes healthcare team to adjust your insulin, other diabetes medications, nutrition and activity levels to help compensate for them when they do occur.

    For example, when engaging in anaerobic exercise like weightlifting many people with type 1 diabetes find it necessary to take a small bolus of insulin prior to or during their workout because anaerobic exercise can actually raise blood sugar.

    What Is Hyperglycemia

    Hyperglycemia is the medical term for high blood sugar . It happens when sugar stays in your bloodstream instead of being used as energy.

    For people without diabetes, a healthy blood sugar level is about 70 to 140 milligrams per deciliter of blood . For people with diabetes, though, the target or healthy blood sugar range depends on a number of other factors, like their age, how long theyve had diabetes, and other health conditions they may have. To achieve good long-term glucose control, people with diabetes should focus on the time they spend in their target range, which is typically 70 to 180 mg/dL. Doctors may say you have hyperglycemia if your blood sugar is higher than 130 mg/dL after not eating or drinking for at least 8 hours or if your blood sugar is higher than 180 mg/dL 2 hours after a meal .

    For people with diabetes, blood sugar control over the long term is important. Your healthcare team will work with you to evaluate your long-term control by looking at your HbA1c and/or the amount of time your blood sugar is within your target range based on data from a continuous glucose monitor, or CGM, or your blood glucose meter.
