How Common Is Low Blood Glucose

WHAT IS LOW BLOOD SUGAR LEVEL?LOW BLOOD SUGAR EXPLAINED

Low blood glucose is common among people with type 1 diabetes and among people with type 2 diabetes who take insulin or some other diabetes medicines. In a large global study of people with diabetes who take insulin, 4 in 5 people with type 1 diabetes and nearly half of those with type 2 diabetes reported a low blood sugar event at least once over a 4-week period.2

Severely low blood glucose, defined as when your blood glucose level drops so low you cant treat it yourself, is less common. Among U.S. adults with diabetes who take insulin or some diabetes medicines that help the pancreas release insulin into the blood, 2 in 100 may develop severely low blood glucose each year.3

Signs That Blood Sugar Levels Are Low

There are a bunch of symptoms that someone with low blood sugar might have. It’s not the same for everybody. The symptoms are as minor as feeling hungry and as serious as having seizures or passing out. Have you ever had low blood sugar? If so, do you remember how it felt? Noticing those problems early can help you if it happens again.

If you have diabetes and you have low blood sugar, you may:

  • feel hungry or have “hunger pains” in your stomach
  • feel shaky or like you’re trembling
  • have a rapid heart rate
  • feel sweaty or have cold, clammy skin
  • have pale, gray skin color
  • have a headache
  • be unsteady or stagger when walking
  • have blurred or double vision
  • feel confused
  • have seizures
  • pass out

If you think your blood sugar level could be low, tell a parent, teacher, or whoever is taking care of you. An adult can help you test your blood and get you treatment so you start feeling better.

No Symptoms Be Alarmed

Surprisingly, the most dangerous episodes of hypoglycemia occur with little or no warning. When low blood glucose occurs on a regular basis, the body can become used to the warning signs and the person may stop noticing symptoms. This is a particularly dangerous condition known as hypoglycemic unawareness. People with this condition might not realize they have low blood glucose until it’s dangerously low seizures and coma are sometimes the first indication of a problem. The good news is that this condition can often be reversed allowing people to once again notice the signs of low blood glucose if hypoglycemia is avoided for a few weeks through careful monitoring of blood glucose.

    If your blood sugar drops low enough for you to become unconscious, you must be taken to the hospital and/or treated with glucagon.

    Glucagon is a hormone that causes the blood sugar to rise. It can only be given by injection. It is used to treat a low blood sugar if a person becomes semi-conscious or unconscious due to a severe low blood sugar. Please ask your nurse for instruction on glucagon. Your doctor will need to write a prescription for glucagon so you can have it available at home.

    • Three glucose tablets
    • 4-6 ounces of fruit juice
    • 2 tablespoons of raisins
    • 6 jelly beans
    • 5-6 ounces of regular soda

    If A Person Is Unconscious

    How to convert AVERAGE BLOOD GLUCOSE into HBA1c

    If a person loses consciousness because of severe hypoglycaemia, they need to be put into the recovery position and given an injection of the hormone glucagon . The injection will raise their blood glucose level.

    The injection should be carried out by a friend or family member who knows what they’re doing, or by a trained healthcare professional.

    You should dial 999 to request an ambulance if:

    • a glucagon injection kit isn’t available
    • there’s nobody available who’s trained to give the injection
    • the injection is ineffective after 10 minutes

    Never try to put food or drink into the mouth of someone who’s unconscious as they could choke.

    If you’re able to give a glucagon injection and the person regains consciousness, they should eat some longer-acting carbohydrate food, such as a few biscuits, a cereal bar or a sandwich.

    You should continue to monitor the person for signs of recurring symptoms in case they need to be treated again.

    • Cannot tell by your symptoms that your blood sugar is low.
    • Have low blood sugar several times a week.
    • Have type 1 diabetes, or have had type 2 diabetes for a long time.

    If you have hypoglycemic unawareness, test your blood sugar often, especially before activities like driving a car. Keep some glucose or sucrose tablets or solution or quick-sugar foods with you. If you take insulin, carry a glucagon emergency kit. You can also give friends and family instructions to treat low blood sugar.

    Talk To Your Doctor Or Nurse

    If you use insulin and your blood sugar is frequently or consistently low, ask your doctor or nurse if you:

    • Are injecting your insulin the right way

    When Blood Sugar Is Too Low

    What a Low Blood Sugar Feels Like

    Glucose is a sugar that comes from the foods we eat, and it’s also formed and stored inside the body. It’s the main source of energy for the cells of our body, and is carried to each cell through the bloodstream. Our brains depend on glucose to function, even when we’re sleeping.

    The is the amount of glucose in the blood. When these levels drop too low, it’s called hypoglycemia . Very low blood sugar levels can cause serious symptoms that need to be treated right away.

    The Causes Of Low Blood Sugar

    Low blood sugar levels can happen to kids with diabetes because of the medicines they have to take. Kids with diabetes may need a hormone called insulin and/or diabetes pills to help their bodies use the sugar in their blood. These medicines help take the sugar out of the blood and get it into the body’s cells, which makes the level of sugar in the blood go down.

    But sometimes it’s a tricky balancing act, and blood sugar levels can get too low. Kids with diabetes need to keep their blood sugar levels from getting too high or too low. How do they do it? With help from grown-ups, they keep three things in balance:

    Each one of these can affect the other. For instance, eating more might mean a kid needs more insulin. And exercising might create the need for an extra snack. Again, a grown-up can help you learn how to juggle those three activities so you keep feeling good.

    Some things that can make low blood sugar levels more likely to happen are:

    • skipping meals and snacks
    • not eating enough food at a meal or snack
    • exercising longer or harder than usual without eating something extra
    • getting too much insulin
    • not timing the insulin doses properly with meals, snacks, and exercise
    • taking a long bath or shower right after an insulin shot

    • 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.

    What Is Low Blood Glucose

    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.

    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.
