Consult your doctor with any questions or concerns you may have regarding your blood sugar levels


What is hypoglycemia?

Hypoglycemia, also called low blood glucose or low blood sugar, happens when your blood glucose drops below normal levels. Glucose comes from food and is an important source of energy for the body.

Hypoglycemia can happen suddenly. It’s usually mild and can be easily treated by eating or drinking something that contains glucose. But if left untreated, hypoglycemia can cause confusion, clumsiness, or fainting. Prolonged hypoglycemia can lead to seizures, coma, and even death.

It’s important to be able to recognize the symptoms of hypoglycemia and be prepared how to correct it.

As always, consult you doctor with any questions or concerns you may have regarding your blood sugar levels.

What are the symptoms of hypoglycemia?

  • Hunger

What causes hypoglycemia?

People with diabetes who take certain glucose-lowering medications may be at risk for hypoglycemia for a variety of reasons: 

  • Eating meals or snacks that are too small, delayed, or skipped
  • Taking too much insulin or other blood-glucose lowing medications
  • Increasing exercise or physical activity

Does hypoglycemia occur in people who don’t have diabetes?

It’s not as common, but people who don’t have diabetes can experience hypoglycemia. diabetic hypoglycemia usually appears in two forms: 

  • Reactive hypoglycemia, which occurs within 4 hours after meals. People with reactive hypoglycemia should follow a healthy eating plan recommended by a registered dietitian.
  • Fasting hypoglycemia can be caused by too little food intake or an overly rapid metabolism. It may also be brought on by certain medications or underlying illnesses. Talk to your doctor for more information.

Symptoms of both reactive and fasting hypoglycemia are similar to diabetes-related hypoglycemia: hunger, sweating, shakiness, dizziness, light-headedness, sleepiness, confusion, difficulty speaking, anxiety, and weakness.

How can I best manage a hypoglycemic episode?

The American Diabetes Association recommends that people experiencing hypoglycemia consume glucose or simple carbohydrates. People who are prone to hypoglycemia reactions may want to consider carrying a glucose product with them at all times.

To quickly and easily raise blood sugar levels to their normal range, many pharmacists recommend products that contain specially formulated glucose. Products like Insta-Glucose offer a variety of advantages:

  • Delivers 24 grams of fast-acting, rapidly-absorbed glucose

After swallowing the glucose, wait 10 minutes and if symptoms do not subside, use an additional tube. If condition persists or recurs, contact a doctor.

People with hypoglycemia unawarness may need to check their blood glucose level more often so they know when hypoglycemia is about to occur.

  • Know your blood sugar range and check your blood sugar regularly with a blood glucose monitor, especially if you’re about to drive or if you’re experienced hypoglycemia unawareness. For people with diabetes, a blood glucose level below 70 mg/dL (milligrams per deciliter) is considered hypoglycemia
  • Take your blood glucose-lowering medications at the same time each day
  • Don’t skip meals. And keep specially formulated glucose products or snacks handy
  • Work with a registered dietitian to develop a meal plan that’s right for you. People with diabetes should eat regular meals, have enough food at each meal, and not skip meals or snacks
