Hypoglycemia is the medical term for a blood sugar (glucose) level that has dropped below normal. Glucose is the body's main source of energy, and if it falls below 70 milligrams per deciliter (70mg/dL), a variety of symptoms and signs may occur. The onset can be rapid and recognizing the symptoms ensures prompt treatment and reduce the chance of serious consequences.
One of the most common causes of hypoglycemia is related to diabetic medications. Diabetes results in abnormally high blood glucose unless people receive treatment. Drugs used to treat diabetes help reduce blood glucose levels, but this can lead to hypoglycemia, especially if the person does not eat enough food after taking their medication or misses a meal. Unusual or unplanned amounts of exercise or excessive alcohol may also cause hypoglycemia in people with diabetes.
