The “Rule of 15” is a guideline for treating hypoglycemia (low blood glucose.) If your blood glucose is under 70 mg/dl, take 15 grams of carbohydrates.
Here are some items that contain 15 grams of carbohydrate:
- 1/2 cup of orange juice
- 3–4 glucose tablets
- 1/3 can regular soda
- 1 dose of glucose gel (in most cases, 1 small tube is one dose)
- 1 tablespoon of honey or syrup
- 1 tablespoon of sugar or 5 small sugar cubes
- 4 LifeSavers
Wait about 15 minutes, then recheck your blood glucose level. If your blood glucose is still low, take another 15 grams of carbohydrates and recheck 15 minutes later to make sure your blood glucose levels have risen.
