What to Know About Reactive Hypoglycemia

Can You be Hypoglycemic Without Having Diabetes?

Updated May 28, 2014

Reactive hypoglycemia occurs in people who do not have diabetes. It's a different type of hypoglycemia than the one that affects people who have diabetes. Although the causes are unrelated, the symptoms of both kinds of hypoglycemia are the same.

Symptoms of hypoglycemia:

  • Trembling or weakness
  • Lack of coordination
  • Drowsiness or confusion
  • Headache
  • Dizziness
  • Double vision
  • Convulsions or unconsciousness

What is the cause of reactive hypoglycemia?

The exact cause of reactive hypoglycemia is still unknown, but there are several hypothesis that might explain why it can happen.
  • Sensitivity to epinephrine, a hormone that is released in the body during times of stress.
  • Insufficient glucagon production. Glucagon is also a hormone which has the opposite effect of insulin. It raises blood glucose levels.
  • Gastric surgeries can also cause reactive hypoglycemia because food may pass too quickly through the digestive system.
  • Enzyme deficiencies can also cause reactive hypoglycemia, but these are rare and occur during infancy.

How to manage reactive hypoglycemia

  • Limit foods with a high sugar content, especially on an empty stomach. For example, eating a doughnut first thing in the morning can trigger a hypoglycemic episode.
  • Eat small, frequent meals and snacks.
  • Eat a varied, high fiber diet, with adequate servings of protein, whole grain carbs and vegetables, fruits, and dairy foods
  • Carry pieces of hard candy with you, for those times when you feel your blood sugar dropping.

What to do if you are having a hypoglycemic episode.

  • Eat or drink something that is a fast sugar source, such as orange juice, regular soda, a few pieces of hard candy, or sugar cubes. This should relieve the symptoms within 15 minutes.
  • Avoid choosing chocolate as a sugar source. The fat in chocolate makes it absorb more slowly and it won't raise your blood sugar up as quickly as you need it too.
  • Make sure to eat a small balanced meal after the symptoms are gone. This will prevent another blood sugar spike and consequent drop.

*A rare type of tumor, called an insulinoma, in the pancreas can also cause hypoglycemia in people who do not have diabetes. If you do suffer from episodes of hypoglycemia, it is wise to follow up with a visit to your doctor, to rule out the possibility of an insulinoma or other medical condition.
