Host: How do you treat low blood sugar? Kathy Reily: A low blood sugar is treated by eating or drinking about 15 grams of carbohydrate. We want to bring the blood sugar up a little bit, not a lot, so the portion is important and 15 grams of carbohydrate is about four ounces of any kind of fruit juice, about six ounces of regular soda or about 3-4 glucose tablets and those amounts will raise the blood sugar in most people above 40 or 50 points and so, it should bring them out of the low range up to perhaps 80, 90 or a 100 which we would say is in the target range.
