• Hypoglycemia is a condition characterized by abnormally low blood glucose (blood sugar) levels, usually less than 70 mg/dl. However, it is important to talk to your health care provider about your individual blood glucose targets, and what level is too low for you.
  • Hypoglycemia may also be referred to as an insulin reaction, or insulin shock.
  • Hypoglycemic symptoms are important clues that you have low blood glucose. Each person’s reaction to hypoglycemia is different, so it’s important that you learn your own signs and symptoms when your blood glucose is low.
  • The only sure way to know whether you are experiencing hypoglycemia is to check your blood glucose, if possible. If you are experiencing symptoms and you are unable to check your blood glucose for any reason, treat the hypoglycemia. Severe hypoglycemia has the potential to cause accidents, injuries, coma, and death.
