What Causes Low Blood Glucose In People With Diabetes

Low blood glucose levels can be a side effect of insulin or some other medicines that help your pancreas release insulin into your blood. Taking these can lower your blood glucose level.

Two types of diabetes pills can cause low blood glucose

  • sulfonylureas, usually taken once or twice per day, which increase insulin over several hours
  • meglitinides, taken before meals to promote a short-term increase in insulin

The following may also lower your blood glucose level

What Are Target Blood Sugar Levels For People With Diabetes

A target is something that you aim for or try to reach. Your health care team may also use the term goal. People with diabetes have blood sugar targets that they try to reach at different times of the day. These targets are:

  • Right before your meal: 80 to 130
  • Two hours after the start of the meal: Below 180

Talk with your health care team about what blood sugar numbers are right for you.

Treating Low Blood Glucose If You Take Medicines That Slow Down Digestion

Some diabetes medicines slow down the digestion of carbohydrates to keep blood glucose levels from rising too high after you eat. If you develop low blood glucose while taking these medicines, you will need to take glucose tablets or glucose gel right away. Eating or drinking other sources of carbohydrates wont raise your blood glucose level quickly enough.

A Low Blood Sugar Level Without Diabetes

A low blood sugar level is uncommon in people who do not have diabetes.

Possible causes include:

  • a gastric bypass
  • other medical conditions, such as problems with your hormone levels, pancreas, liver, kidneys, adrenal glands or heart
  • some;medicines, including quinine

See a GP if you think you keep;getting symptoms of a low blood sugar level. They can arrange some simple tests to check if your blood sugar level is low and try to find out what’s causing it.

Why Is It Important To Recognize A Low Blood Sugar Level

Low blood sugar levels can happen with Type 1 and Type 2 diabetes. Low levels are more likely to happen if you use insulin. Hypoglycemia can cause you to have falls, accidents, and injuries. A blood sugar level that gets too low can lead to seizures, coma, and death. Learn to recognize the symptoms early so you can get treatment quickly.

What Does It Mean To Have Low Blood Sugar

Low blood sugar is defined as the glucose levels in blood dropping below 70 milligrams per deciliter, impacting the body’s ability to function normally, according to Healthline. Also referred to as hypoglycemia, low blood sugar is typically accompanied by symptoms such as blurry vision, rapid heartbeat and fatigue. Low blood sugar requires immediate treatment, usually in the form of a small snack of carbohydrates.

Hypoglycemia can be caused by skipping meals, eating less than normal, or exercising more than usual, reports Healthline. It is also common in people with diabetes, especially if too much insulin is taken in proportion to the amount of sugar consumed. While mildly low blood sugar levels can be quickly resolved, severely low blood sugar levels can be life-threatening and lead to seizures, comas or death. For this reason, diabetics are advised to carry a glucagon kit to raise their blood sugar levels immediately when necessary.

Hypoglycemia has a wide range of symptoms that vary with the individual, according to Healthline. However, a condition called hypoglycemic unawareness affects the symptoms and can prevent a person from noticing rapidly decreasing blood sugar levels. Blood glucose meters are available to test and diagnose low blood sugar immediately. If blood sugar levels are regularly dropping without cause, a physician may be needed to diagnose the underlying condition.

What Are The Symptoms Of Low Blood Sugar In Dogs

What a Low Blood Sugar Feels Like

The symptoms of low blood sugar as:

  • Loss of appetite or an increased hunger
  • Visual instability, such as blurred vision or even blindness, causing your dog to walk cautiously or bump into objects they are used to walking around
  • Disorientation and confusion your dog may show an apparent inability to complete basic routine tasks that they are used to performing
  • Weakness, low energy, loss of consciousness
  • Seizures, although rare
  • Tremors, shivering, or uncontrollable shaking
  • Heart palpitations
  • Unusual behavior

If your dog is experiencing these symptoms, or you believe that they have low blood sugar you should take them to the veterinarian if they are conscious and you do not fear that they will lose consciousness prior to getting to the veterinary clinic.

Your Diabetes Devices And Hypoglycemia

Several insulin pumps are now available that make managing blood sugar levels easier, particularly when connected to a glucose meter or a CGM.;

Some of the most important advantages of CGM devices are the improved insulin control and the ability to detect trends and lows early. With improved technology, it is; now possible for parents to track blood sugar trends in their kids even when they are hundreds of miles apart .

In addition, automated insulin delivery systems, also known an artificial pancreas or a hybrid closed-loop system, will automatically adjust insulin to match your bodys need to help you spend more time in your target range.;

Resources that provide people with T1D and their families with more detailed information about pumps and CGM devices are available through JDRF here. For people looking for a deeper understanding of technology that helps people with T1D better manage their blood sugar, JDRF resources are available here. ;

Faq: Frequently Asked Questions

Who is most at risk for hypoglycemia? Aside from diabetics, Dr. Jennifer Shine Dyer notes that children are more prone toexperience episodes of hypoglycemia because of their smaller body size, as well as having less fat to burn to maintain energy when glucose levels are low. Eating meals every 4 to 6 hours should maintain glucose levels if this is the only cause of hypoglycemia, she says.


How do I know it’s low blood sugar?;;To know if you’re suffering from hypoglycemia, you’ll need to begin tracking your glucose levels under the supervision of your doctor. Drugstores and pharmacies carry test strips, as well as glucose meters, which will help. You can even see the effect that different foods have on your body by checking your blood sugar after eating.

Does fasting affect my blood sugar levels?;Yes, going without food can trigger hypoglycemia. If you have diabetes and are concerned about hypoglycemia, aim to eat smaller, more frequent meals and snacks that are low in processed sugars every three hours or so.

Does alcohol consumption trigger low blood sugar?Excessive alcohol consumption, defined as more than one drink per day for women and more than two drinks per day for men, especially with little food, can keep your liver from releasing glucose, which can lead to hypoglycemia.

What Is Low Blood Glucose

How To Treat Low Blood Sugar (Diabetes Type 2)

Low blood glucose, also called low blood sugar or hypoglycemia, occurs when the level of glucose;in your blood drops below what is healthy for you. For many people with diabetes, this means a blood glucose reading lower than 70 milligrams per deciliter .1 Your number might be different, so check with your doctor or health care team to find out what blood glucose level is low for you.

What Should I Do If I Have Symptoms Of A Low Blood Sugar Level

  • Check your blood sugar level, if possible. Your blood sugar level is too low if it is at or below 70 mg/dL.
  • Eat or drink 15 grams of fast-acting carbohydrate. Fast-acting carbohydrates will raise your blood sugar level quickly. Examples of 15 grams of fast-acting carbohydrates:
  • 4 ounces of fruit juice
  • 4 ounces of regular soda
  • 2 tablespoons of raisins
  • 1 tube of glucose gel or 3 to 4 glucose tablets
  • Check your blood sugar level 15 minutes later. If the level is still less than 100 mg/dL, eat another 15 grams of carbohydrate. When the level returns to 100 mg/dL, eat a snack or meal that contains carbohydrates. This will help prevent another drop in blood sugar.
  • Teach people close to you how to use your glucagon kit. Your blood sugar may be too low for you to be awake. People need to know when and how to use your kit.
  • What Extreme Conditions Can Occur If Hypoglycemia Is Left Untreated

    Although severe episodes which can trigger potentially life-threatening comas are rare, they require immediate emergency room care, so its best to make sure you are tracking your blood sugar so that you never have to worry about getting to that point. A drop in blood sugar means less fuel for your brain, so its critical for your body to receive enough glucose. Hypoglycemia that leads to extended, reduced brain function is the biggest concern, as this can lead to seizures and loss of basic bodily functions controlled by the brain, which can ultimately lead to death, explains Dr. Dyer.

    The Effects Of Low Blood Sugar On Your Body

    Every cell in your body needs energy to function. The main source of energy might come as a surprise: Its sugar, also known as glucose. Blood sugar is essential to proper brain, heart, and digestive function. It even helps keep your skin and vision healthy.

    When your blood sugar levels fall below the normal range, its called hypoglycemia. There are many identifiable symptoms of low blood sugar, but the only way to know if you have low blood sugar is by taking a blood glucose test.

    Learn more about the symptoms of low blood sugar, as well as the long-term effects on the body.


    most common reasons for low blood sugar are some medications used to treat diabetes, such as insulin.

    In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesnt make enough insulin, or your body cant use it properly. Too much insulin or oral diabetic medication can lower the blood sugar level, leading to hypoglycemia.

    However, contrary to popular belief, low blood sugar isnt exclusive to diabetes, though it is rare. It can also happen if your body makes more insulin than it should.

    Another possible cause of low blood sugar is drinking too much alcohol, especially over long periods of time. This can interfere with the livers ability to create a buildup of glucose and then release it into your bloodstream when you need it.

    Other causes include:


    How Is Hypoglycemia Diagnosed

    WHAT IS LOW BLOOD SUGAR LEVEL?LOW BLOOD SUGAR EXPLAINED

    If you suspect you have low blood sugar, its important to check your blood sugar right away. If you dont have a meter and youre on diabetes medications that increase insulin, talk with your doctor about getting a blood glucose meter.

    If you experience low blood sugar often say, a few times a week see your doctor right away to determine why. Your doctor will begin your visit by requesting your medical history, asking questions about your eating habits, and learning more about the symptoms youre experiencing.

    If you dont have diabetes but suspect you have hypoglycemia, talk with your doctor about your symptoms. They will perform a physical examination. They will use three criteria, sometimes referred to as Whipples triad, to diagnose low blood sugar. These include:

    • Signs and symptoms of low blood sugar. Your doctor may require you to fast, or abstain from drinking and eating for an extended period of time, so they can observe your low blood sugar signs and symptoms.
    • Documentation of low blood sugar when your signs and symptoms occur. Your doctor will order a blood test to analyze your blood sugar levels in a laboratory.
    • Disappearance of the signs and symptoms of low blood sugar. Your doctor will want to know whether the signs and symptoms go away when your blood sugar levels are raised.

    To perform a blood sugar test, you will need to prick your finger with a lancet . Youll put a small sample of blood from this onto a strip inserted into the blood glucose meter.

    Other Causes Of Sugar In Urine

    A rare condition called renal glycosuria can cause a person to have sugar in their urine even if their blood sugar levels are normal. This condition occurs when the kidneys’ filtration system doesn’t work correctly and the kidneys eliminate glucose through urine, according to the National Organization for Rare Disorders17.

    Renal glycosuria rarely causes side effects. In fact, it is typically asymptomatic, meaning that it has no symptoms at all, and is therefore usually not a cause for concern.

    Warning Signs Of Low Blood Sugar

    Hypoglycemia can cause both short- and long-term complications. Know the signs so that you can treat the condition as soon as you’re aware of it.

    As a person living with diabetes, you know how important it is to reduce blood sugar when it is too high, a phenomenon called hyperglycemia. But blood sugar that is too low, or hypoglycemia, is equally critical to avoid.

    Hypoglycemia happens when the amount of blood glucose drops to a level that’s too low to sustain normal functioning,” says;Erin Palinski-Wade, RD, CDCES, who is based in Sparta, New Jersey. “In most people, this is defined as a blood sugar level at or below 70 milligrams per deciliter .”

    Hypoglycemia is common among people with type 2 diabetes, according to a review published in June 2015 in the journal PLoS One. Individuals with the condition had an average of 19 mild or moderate episodes of hypoglycemia per year and nearly one severe episode per year on average, according to the researchers. Low blood sugar was particularly common among those taking insulin.

    This decrease in blood sugar levels can cause both short-term;complications, like confusion and dizziness, as well as more serious issues, including seizures, coma, and, rarely, death, according to the American Diabetes Association .

    Hypoglycemia is usually the result of a too-high dose of insulin or a change in diet or exercise habits, according to Harvard Health Publishing.

    Digestive Endocrine And Circulatory Systems

    After you eat, your digestive system breaks down carbohydrates and turns them into glucose. Essentially, glucose is your bodys fuel source.

    As your sugar levels rise, your pancreas releases a hormone called insulin, which helps glucose get taken up and used by cells throughout your body. If you have insulin-dependent diabetes, you must take the right about of insulin to get the job done.

    Any excess glucose goes to your liver for storage.

    When you go a few hours without eating, blood sugar levels go down. If you have a healthy pancreas, it releases a hormone called glucagon to make up for the absence of food. This hormone tells your liver to process the stored sugars and release them into your bloodstream.

    If everything works as it should, your blood sugar levels should remain in the normal range until your next meal.

    Insufficient blood sugar levels can cause a rapid heartbeat and heart palpitations. However, even if you have diabetes, you may not always have obvious symptoms of low blood sugar. This is a potentially dangerous condition called hypoglycemia unawareness. It happens when you experience low blood sugar so often that it changes your bodys response to it.

    Normally, low blood sugar causes your body to release stress hormones, such as epinephrine. Epinephrine is responsible for those early warning signs, like hunger and shakiness.
