Hypoglycemia is a condition in which your blood sugar (glucose) level is lower than normal.
The normal blood glucose range in healthy individuals is between 70 and 125 mg/dl. During times of prolonged physical activity, the glucose level can dip below 50 mg/dl. After carbohydrate-rich meals, it can soar to over 180. Hypoglycemia needs immediate treatment when blood sugar levels are low. For many people, a fasting blood sugar of 70 milligrams per deciliter (mg/dL), or 3.9 millimoles per liter (mmol/L), or below should serve as an alert for hypoglycemia. But your numbers might be different. If blood sugar levels become too low, signs and symptoms can include:
- An irregular or fast heartbeat
- Pale skin
- Tingling or numbness of the lips, tongue or cheek
If you have these symptoms, it might be hypoglycemia.
