How Do You Know When Your Blood Sugar Is Low


Checking For Low Blood Sugar Levels

HOW DO YOU FEEL IF YOUR BLOOD SUGAR IS HIGH OR LOW?

The warning signs of hypoglycemia are the body’s natural response to low blood sugar levels. When blood sugar levels fall too low, the body releases the hormone adrenaline, which helps get stored glucose into the bloodstream quickly. This can make someone:

  • pale
  • start shaking
  • have an increased heart rate

If the hypoglycemia isn’t treated, more serious symptoms may happen, such as drowsiness, confusion, seizures, and loss of consciousness.

The only way to know for sure if you’re having a low blood sugar level is to test. Blood sugar levels can be tested with a . This computerized device measures and displays the amount of glucose in a blood sample. But if you can’t quickly check your blood sugar level, it’s important to treat yourself for hypoglycemia immediately to prevent symptoms from getting worse.

Sometimes a person with diabetes may have symptoms of low blood sugar levels, but blood sugar levels are not actually low. This is a called a false reaction. The hormone adrenaline is not just released when blood sugar drops too low it’s also released when blood sugar levels fall quickly when they’re too high. If you’re having a false reaction, you might actually have blood sugar levels in a healthy range but feel as if you have low blood sugar. Testing blood sugar levels before treating yourself for hypoglycemia can help you figure out if you’re having a false reaction.

What Causes Low Blood Glucose

  • Symptoms occur when blood glucose levels fall below 70 mg/dl a condition known as hypoglycemia.
  • In most cases, low blood glucose results from overtreatment: Either taking too much diabetes medication or not eating enough food. Higher doses of medicine than the person actually requires can also lead to hypoglycemia.
  • People who aim for too-low values on their A1C test tend to experience more frequent drops in blood glucose.
  • Vigorous exercise doesn’t just burn calories, it also burns blood glucose! Hypoglycemia can occur unless blood glucose levels are carefully monitored during and after exercise.
  • Not eating on a regular basis can deprive the body of glucose and make it difficult to prevent hypoglycemia. Eat balanced meals throughout the day and always keep a snack on hand.

Treating Mild To Moderate Hypoglycemia

If you start feeling any of the symptoms listed above, check your blood sugar as soon as possible, then follow the chart below to treat low blood sugar. If you have any concerns, or cant test immediately, its best to treat first and check when possible.

What Are Blood Sugar Levels

Blood sugar levels, also known as blood glucose level, is the level of sugar/glucose present in the blood. Glucose is a simple version of sugar which comes from the food we eat. Therefore, the more food you consume with high sugar levels over a period of time, will typically increase your blood sugar level.;

Glucose comes from the foods we eat and its sugar content. When a person consumes a food with high sugar content, that is turned into glucose. The glucose is then absorbed into the bloodstream with the support of insulin. This is then distributed between the bodys cells and used as energy.

Foods high in glucose include most carbohydrates and a handful of proteins and fats. Most foods contain glucose as it is simply a natural sugar that occurs in most dietary forms. However, it is carbohydrates that contain the most sugar and 100% of it turns into glucose, through the process mentioned above, once consumed. The concentration of glucose present in the blood will determine your blood sugar level.

Your blood sugar level can either be low, normal or high. Depending on what you eat and health conditions, it will vary from person to person. Here is a breakdown of how your blood sugar works and how low or high blood sugar levels happens:

How Can I Prevent Hypoglycemic Episodes

Effects of Low Blood Sugar on the Body

The key to preventing hypoglycemic events is managing diabetes:

  • Follow your healthcare providers instructions about food and exercise.
  • Track your blood sugar regularly, including before and after meals, before and after exercise and before bed.
  • Take all your medications exactly as prescribed.
  • When you do have a hypoglycemic event, write it down. Include details such as the time, what you ate recently, whether you exercised, the symptoms and your glucose level.

Tingling Hands And Feet

Over the years, hyperglycemia can begin to impact nerve function and eventually cause nerve damage, called neuropathy, Dr. Hatipoglu says. The most common kind of neuropathy is peripheral, according to the NIDDK, which affects the extremities. You might start noticing feelings of tingling, numbness, or burning in your hands, feet, arms, and legs, per the Mayo Clinic.

Complications From Spells Of Hypoglycemia

Mildly low blood sugar levels are somewhat common for people with diabetes; however, severely low blood sugar levels can be life threatening. They may lead to seizures and nervous system damage if left untreated long enough. Immediate treatment is critical.


Its important to learn to recognize your symptoms and treat them fast. For people at risk for low blood sugar, having a glucagon kit a medication that raises blood sugar levels is important. Talk with your doctor for more information.

You may also want to talk with friends, family members, exercise partners, and co-workers about how to care for you if your blood sugar drops too low.

Its important for them to learn to recognize low blood sugar symptoms and know how to use the glucagon kit, as well as understand the importance of calling 911 if you lose consciousness.

Wearing a medical identification bracelet is a good idea. It can help emergency responders care for you properly if you need emergency attention.

Treat low blood sugar as soon as possible. Avoid driving if you are experiencing low blood sugar, as it can increase your risk for having an accident.


There are several ways that you can prevent low blood sugar.

What Drinks And Foods Raise Blood Sugar Fast

  • 4 teaspoons of sugar
  • 1/2 can of regular soda or juice

Many people like the idea of treating low blood sugar with dietary treats such as cake, cookies, and brownies. However, sugar in the form of complex carbohydrates or sugar combined with fat and protein are much too slowly absorbed to be useful in acute treatment.

Once the acute episode has been treated, a healthy, long-acting carbohydrate to maintain blood sugars in the appropriate range should be consumed. Half a sandwich is a reasonable option.


If the hypoglycemic episode has progressed to the point at which the patient cannot or will not take anything by mouth, more drastic measures will be needed. In many cases, a family member or roommate can be trained in the use of glucagon. Glucagon is a hormone that causes a rapid release of glucose stores from the liver. It is an injection given intramuscularly to an individual who cannot take glucose by mouth. A response is usually seen in minutes and lasts for about 90 minutes. Again, a long-acting source of glucose should thereafter be consumed to maintain blood sugar levels in the safe range. If glucagon is not available and the patient is not able to take anything by mouth, emergency services should be called immediately. An intravenous route of glucose administration should be established as soon as possible.

    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 Treated

    When your blood sugar levels are too low, eating something made of carbohydrates is key. If you have diabetes, try to keep high-carbohydrate snacks on hand.

    The American Diabetes Association recommends that your snack have at least 15 grams of carbohydrates. Some good snacks to keep on hand include:


    • glucose tablets
    • honey or table sugar
    • jelly beans or gum drops

    You also can take glucose tablets to rapidly raise your blood sugar if its low. These are available without a prescription. Its important to check how many grams are in each tablet before taking them. Aim to get 15 to 20 grams of carbohydrates.

    Wait 15 minutes after eating or taking a glucose tablet, and test your blood sugar again. If your blood sugar is not going up, eat another 15 grams of carbohydrates or take another dose of glucose tablets. Repeat this until your blood sugar level starts to rise.

    If your regularly scheduled meal is not for a while, eat a small snack after the low blood sugar episode.

    Be sure not to overeat! This could lead to blood sugar levels that are too high.

    What Are Some Tips To Prevent Nighttime Blood Sugar Level Dips

  • Check your level before bed.;According to Sulay Shah, M.D., a board certified endocrinologist, the only way to know if you are at risk is to monitor your blood glucose levelsas there arent always telltale signs.If you check and you notice that your levels are close to 70 mg/dL at bedtime, then you know you might be at risk, Dr. Shah says. In this case, he recommends eating some complex carbohydrates, like a peanut butter sandwich, an apple with peanut butter or one slice of multigrain toast with some avocado.
  • Dont skip dinner.;If you arent eating dinner, Dr. Shah advises skipping your rapid-acting insulin or medicine, like glipizide or glimepiride, that can decrease your blood sugar levels. The goal here is to match your meal and medication, he says.
  • Monitor your alcohol intake.;If you notice that your blood sugar is dropping after having a few beers or vodka sodas, then Dr. Shah warns that you may need to try to eat complex carbohydrates with the alcohol. Dr. Shah notes that blood sugar tends to drop 3 to 4 hours after drinking alcohol. When you regularly drink alcohol, you are decreasing the amount of stored glucose in the liver which helps to maintain a blood sugar in normal range, he explains.

    One of the challenges of managing diabetes is maintaining consistent blood sugar levels. Even with diligence, some situations can cause high blood sugar, or;hyperglycemia, while others can bring on low blood sugar, or;hypoglycemia.

    After all, its not just carbohydrate intake that influences the amount of glucose coursing through your bloodstream when you have type 2 diabetes. Emotional stress and certain medications can increase your blood sugar levels, and a boost in activity can cause it to drop, says Megan ONeill, CDCES, a medical science liaison for diabetes care at Abbott healthcare company in Monterey, California. Sometimes people experience a spike in their blood sugar early in the morning due to the dawn effect, a temporary surge of hormones that occurs as the body prepares to wake, according to the Cleveland Clinic.

    For people with diabetes, managing blood glucose levels is especially important, ONeill says. Levels that are too low or high can result in;complications that affect your kidneys, heart, and vision, reduce your quality of life, require expensive interventions, or even be fatal.
