Continuing the discussion from Do you love to bicycle? Come say hi!:
How do you use your CGM during exercise to help prevent lows (or highs for that matter)? Also, how have you overcome challenges in using your CGM during exercise?
For me, I ride a recumbent tricycle and find I am able to wear shorts with a belt so I can “easily” see the CGM when I stop at a traffic light. However, I am plagued by at least two things.
The first is when the CGM drops below my low threshold and the numbers turn red. I can’t read them in bright sunlight. I sort of solved this by turning off the low alarm which keeps the numbers white until I fall below 55 then they are red again.
The second is once low, the CGM (really it’s the interstitial fluid) takes a longer time to catch up to what’s really happening with my BG, so I might think I am low and over-treat. Of course, the reality is my rides are so strenuous that I am constantly working to keep my BG up, so even when the CGM is reading too low, I will need to eat some more glucose tabs and/or a protein bar at some point.
