| After exercising you need to replace the glucose you burned up within 45 minutes with something startchy like a sandwich. This will stop your liver dumping glucose into the system. This is a general guideline for any exercise and especially for a diabetic. I find that if I dont replace the glucgen fast I spike and suffer from fatigue the next day which makes exercising even more difficult. Eat within 45 minutes and bolus as normal, but you may need to reduce the bolus as it will absorb quickly and be used more effectively due to the increased heart rate. |
