If your blood sugar levels are 70 mg/dL or lower, you should consume 15 grams (g) of fast-acting carbohydrates. Try a half-can of regular (not diet) soda, ½ cup of fruit juice, 1 tablespoon (tbsp) of honey, or sugar tablets. Recheck your levels after 15 minutes and repeat if necessary (called the “rule of 15s”).
