What to Do if You Have Low Blood Sugar

Low blood sugar is also called hypoglycemia (hy-po-gly-SEE-mee-uh).

  1. If your blood sugar is below 70 mg/dL, or if you have any of the symptoms of low blood sugar, eat or drink 15 to 20 grams of glucose or simple carbohydrates. The items below are commonly used:
    • 1/2 cup of fruit juice or regular soda (not diet)
    • 1 tablespoon of sugar, honey, or corn syrup
    • 2 tablespoons of raisins
    • 1 cup of low-fat (1%) or fat-free milk
    • glucose tablets (follow package instructions)
  2. Wait 15 minutes. Then check your blood sugar again.
  3. If your blood sugar is still below 70 mg/dL, or if you do not feel better, repeat step 1 every 15 or 20 minutes until your blood sugar is 70 mg/dL or above.
  4. If your next meal is 1 hour or more away, eat a snack once your blood sugar is 70 mg/dL or above.
  5. If you still do not feel better, or if your blood sugar stays below 70 mg/dL, call your health care provider right away.

You should have a medical ID with you at all times, which can offer important information to medical personnel if you are unable to speak. For example, the ID can state that you have diabetes and whether or not you use insulin, and include drug allergy information.
