The Risks of Activity
If you are taking diabetes medication or insulin, hypoglycemia (low blood glucose), can be a real concern. Speak with your healthcare team before starting a new exercise plan or making changes to your current plan.
Check your blood glucose levels before and after exercise. Learn your own signs and symptoms of low blood glucose. Common signs are trembling, sweating, anxiety, hunger, nausea, confusion, dizziness or blurred vision. Low blood glucose can cause people to lose consciousness, if not treated quickly. If you feel any of these symptoms, stop the activity and test your blood glucose, if you can. If not, to be safe, simply treat it as hypoglycemia and ingest fast acting carbohydrate, such as glucose tablets. If after 15 minutes, you still feel low or your blood glucose is less than 4 mmol/L, take another tablet. Be sure to follow up with your normally scheduled meal or snack to prevent post-exercise low blood glucose.
