Question: What's the best way to prevent lows (or highs!) during exercise?
Answer: Exercise can be a very effective way to help maintain good blood glucose control, but special attention needs to be made in those with diabetes to ensure blood glucose levels don’t drop too low, or in some cases, become too high.
Exercising causes our muscles to use up glucose, which comes from eating carbohydrate-rich foods. This means that not eating adequate carbohydrates before exercise could potentially cause hypoglycemia, or low blood glucose (less than 70 mg/dL), which can be dangerous.
