What Does It Mean If Your Blood Sugar Is Low


What Should I Do If I Experience A Hypoglycemia

HOW TO STOP LOW BLOOD SUGARS FROM RUINING YOUR WORKOUTS? | Diabetes

Low blood sugar can be treated quickly with fast-acting glucose. If you are at risk for lows, you should always have something fast and sweet with you. Glucose tabs, for example, are available at any pharmacy, are relatively affordable, and are designed to digest quickly and raise blood glucose fast.

Other options are fruit juice, regular soda, candies , or other . It is important that whatever you use to treat the low does not contain a lot of fat or fiber, which slows digestion and takes longer to raise blood sugar.

The general guidelines are to eat 15-20 grams of glucose or simple carbohydrates then check your blood sugar again in 15 minutes. If you are still low, repeat.

If you experience low blood sugars often, talk to your doctor. Together, you’ll be able to figure out why they are happening and then make adjustments, so they don’t happen so often.


So What Do I Need To Know

Maybe it’s more accurate to say that people with type 2 diabetes who take certain types of medication are more at risk for lows. We’re getting closer! But to get to the truth, we should take a look at someone without diabetes. Is it possible for them to have lows, too?

Theoretically yes, especially if doing long-lasting physical activities without proper food intake. Additionally, extreme stress and binge drinking are also common causes of low blood sugar for people without diabetes.

However, it’s pretty rare because as soon as BG’s drop, the body’s natural counterregulatory system kicks in, raising blood sugar back to normal levels. It stops the production of insulin and activates its stress system.

I’ve never experienced hypoglycemia , even though I am very active and eat a rather low carb diet.

When To Call 911

Your friend, relative, or coworker should call 911 for help if:


  • You pass out and no glucagon is available
  • You need a second dose of glucagon
  • You had glucagon, but are still confused
  • Your blood sugar stays too low 20 minutes after treatment or doesnt respond to your usual treatments

The emergency medical technicians can give you IV sugar . This raises your blood sugar level right away. You might need to stay in the hospital for a few hours.

NEVER be afraid to call 911 or ask someone to call 911 for you if you are concerned .

Other things to know about hypoglycemia:

It takes time for blood sugar to rise after eating, and its important to give your first treatment time to work. Use the table above to guide your treatment and timing instead of eating until you feel better, which will almost always lead to eating too much.

Hypoglycemia can be common with certain types of exercise. Managing blood sugar during and after physical activity is important and is something that a lot of people with T1D have questions about. JDRF has a number of resources available for people with T1D and their families, many of which can be found here.

What Are Target Blood Sugar Levels

While your target blood sugar levels may be different from another person’s, the ADA tells most adults with diabetes to shoot for a blood glucose level of 80 to 130 milligrams per deciliter before a meal and less than 180 mg/dL one to two hours after a meal.

Doctors can also measure your average blood sugar levels with an A1C test, which can give you an idea of how high or low your glucose levels have been over the past few months. Most people with diabetes will want to keep their A1C levels to less than 7 percent, according to the ADA.

Hypoglycemia: Battling low blood sugar

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.

A low blood sugar level triggers the release of epinephrine , the fight-or-flight hormone. Epinephrine is what can cause the symptoms of hypoglycemia such as thumping heart, sweating, tingling and anxiety.

If the blood sugar level continues to drop, the brain does not get enough glucose and stops functioning as it should. This can lead to blurred vision, difficulty concentrating, confused thinking, slurred speech, numbness, and drowsiness. If blood sugar stays low for too long, starving the brain of glucose, it may lead to seizures, coma and very rarely death.

    If A Person Is Unconscious

    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.
