Hypoglycemia or low blood sugar occurs when blood sugar drops, sometimes to dangerously low levels.

If you have diabetes, it is critical to know the signs of low blood sugar and how to treat low blood sugar. 

Look out for these symptoms of hypoglycemia:

  • Irregular heart rhythm
  • Fatigue
  • Pale skin
  • Shakiness
  • Anxiety
  • Sweating
  • Hunger
  • Irritability
  • Tingling sensation around the mouth
  • Crying out during sleep

If you are worried that your blood sugar is low, follow the 15-15-15 rule.

  1. Check your blood sugar. If it is less than 70 mg/dL (or other level told to you by your health care provider), consume 15g of quick acting carbohydrates. This could be simple sugars like fruit juice, honey, or syrup.
  2. Wait 15 minutes. Check blood sugar again, and if it is still lower than 70 mg/dL, consume 15 more grams of carbohydrates.
  3. Wait 15 minutes. If blog sugar is still below 70 mg/dL, contact your healthcare provider or local emergency services immediately. Do not attempt to drive to the hospital.
