Exercise to lower blood sugar


I have been running on a treadmill when my blood sugar is higher than what I feel comfortable with. I watch my sensor. It used to really bug me when I was high for too long, like 10.5mmol. Now I can jog on the treadmill for 5-10 minutes and it will come down, then I am happy again. I am so afraid of having complications. I have been a type 1 for almost 24 years, with no complications and I have been having the best control on the pump. My a1c has been in the 6.5-6.9 range and few lows.


Good for you for adopting this tactic. It’s not always convenient when the blood sugar decides to go higher and you’re ready for some down time. I see exercise as a magic catalyst that sensitizes the body to insulin’s action and clearing glucose from the system. The CGM has enabled us to respond to glucose swings in a timely way. I’m glad to read that you’ve found the sweet spot between good control with few lows. Keep up the good work!

Thankyou so much. I strive for the best control I can get and feel let down when I go high. I also found that the insulin seems to be working better since exercising. I am a small person so I find that only 10-15 minutes of walking/jogging is a small price to pay for a high bloodsugar. I am usually watching the sensor to wish the arrow to trend down. I can’t stand it when I am high for very long. By high I mean between 10 and 13 mmol.

I find my best overall BG control happens when I use 20-30 minute walks to cut off post-meal “BG mountain-tops.” This is definitely superior to using insulin to correct. Exercising when meal insulin is peaking is a potent combo.

I totally agree!


I’ve been going to physical therapy for a few weeks now (hip bursitis). They have been having me lift weights with my legs, etc., a real change from my daily don’t do much routine. I noticed that a session of PT will knock my BG diwn by 20-30 points. So I’ve had to let my BG rise beforehand to avoid going hypo.


I pulled up my data from dexcom clarity and it showed that the first week I wasn’t exercising that my average was


I usually rise about three hours after supper. I really don’t feel like exercising past 730pm.


I am happy you found something that works for you. I use the Leslie Sansone videos (walk at home exercises) and a bike and the results are amazing. I see my readings down to 5 to 5.5.

The truth be told here is that I also pay attention to what I eat. I stick with whole foods and I use the glycemic index as well. Continued success to you.


I had a problem with my knee in January 2019. I couldn’t do a deep bend with my right leg and my knee was swelling & felt bruised. So I wasn’t walking on the treadmill. I got a stationary bike instead. Now it is better that the weather has warmed up a little bit. I don’t feel so old anymore.


Stationary bikes are great options for diabetics. My blood sugar drops significantly when I exercise and so I love doing it at home, so that I am free to stop whenever I need to and that I can also break it up into bits and pieces. Thanks for the response and all the best.


Only 2 pieces of hardware are needed to control diabetes. A scale and a CGM.

If you eat, dose and exercise to your CGM and Scale, I am sure that you will find you can control your diabetes far better than any fad eating plan or exercise. CGM + Scale gives real time actionable feedback with which you can take lots of different avenues to correct as needed. Variety makes life and living with this scourge much more enjoyable. Set plans have proven to fail over and over again.

But I don’t think the point of the post was actually just controlling spikes, but rather that exercise is another way of aiding in the control of diabetes. The other benefits of exercise is strengthening the cardio system which is also important for people with diabetes. You don’t get this with the scale and CGM. There are aspects of exercise that help with the mental well being. Exercise also helps to build strength and balance.
