Good question. Generally people would say it makes your BG levels low and you may have a seizure/ black out. And that is actually true most of the times but I have seen the opposite as well. For eg I was at 194 at the start of the workout and after an hour of brisk walking followed by 45 minutes of gym I was at 395. Wow. I was laughing at myself, as it would have been better to have a chocolate bar instead. : ))

This has not been a one off case and I have witnessed it a no. of times. I do get lows as well after workouts, but it is not guaranteed.

I feel understanding T1's is a bit more difficult as compared to T2's. So better be prepared for both highs as well as lows. Good luck and take care.

The biggest risk is that your blood sugar goes low. Before you do any hard exercise it is a good idea to have eaten at least 6 hours prior. Your body needs some fuel to burn. Generally the rule is that for every 30-45 min of exercise consume some 15-20 grams of carb. But your body may require more or less. When you work out ensure that keep some fast acting carb on hand like glucose tablets or jelly beans. Make sure that you test before you work out and don't start unless your BG is above 100. A good range before working out is 100-160. Also it is a good rule to check your BG every 30 min as you work out at first until you figure out how your body will react. Different exercises have different effects on your BG. Aerobic exercises tend to slowly lower your BG as your cells use their fuel. Some hard anaerobic exercises like weight lifting, sprints, and cross fit can actually cause a rise in BG in the first 30 min then a fall because your liver quickly releases it's glucagon stores to provide energy to your muscles. When you start to feel bad just test and take a break and eat some quick acting carb and wait 20-30 min and you can start up again. You just need to start off slower than normal to rediscover your limits. Also remember to check your BG after the work out. Hard exercise can cause your body to use insulin a lot more effectively for 12 to even 24 hours after a workout. So you need to ensure that you don't go low in the hours following a workout or you can give give a small increase to your carb to insulin ratio. You just need to find out what works best for you best of luck!

I want to add to Adam's excellent response: I would also like to add this little caveat from the ADA: "If your blood glucose is high before starting exercise, check your blood or urine for ketones. If you test positive for ketones, avoid vigorous activity." (see ~ )

Also a safety item to keep in mind if one happens to hypo during exercise: keep your BG meter handy and at the first sign of a low, check your BG levels and then if going low, follow the 15/15 plan: "If some one is experiencing a low test first.
If it is below 70 or dropping give them 15 grams of a fast acting carbohydrate.
Wait 15 minutes and test again.
If it is not going up, administer another 15 grams of a fast acting carbohydrate.
Wait 15 minutes and test again.
Repeat this until numbers begin to rise.

If things are not turning around by the third time, you may want to call 911" for more ~

I pray you exercise safely!
