Hypoglycemia (Low Blood Sugar)

What is hypoglycemia?

Hypoglycemia is a condition characterized by a glucose (blood sugar) level that is too low to effectively fuel the body's blood cells. Glucose is the main source of fuel for the body. According to the National Institute for Diabetes and Digestive and Kidney Diseases (NIDDK), the good range of blood sugar is approximately 60 to 120 mg/dL (milligrams of glucose per deciliter of blood). Blood sugar levels under 60 mg/dL are too low and are considered unhealthy.

Hypoglycemia may be a condition by itself, or may be a complication of diabetes or another disorder. It is most often seen as a complication of diabetes, which is sometimes referred to as insulin reaction.
