T1 here for 42 years. I row on a rowing machine or I ride a bicycle as primary forms of exercise and do so for 40mins to an hour. If I don’t put my basal rate at ZERO during, or even half an hour prior, I end up low during exercise typically 50-60 BGS. Then approximately 1 hour later, after exercise is over, I put my basal rate back to normal and usually I end up 140-160 about an hour after. What is everyone else doing in this situation? Are you doing a temporary higher basal to deal? Are you taking a smaller correction amount to now knock down the higher BG. Yesterday was on the bike for an hour. Set temp basal at 0% for 1/2 hour prior and during ride. Still was at 50 BG with 15 minutes left so took 12 Grams of carb and continued on. Finished ride around 80 BGS and then the rise happened. Corrected at 165 BGS with half the normal correction amount, still end up bottoming out 4-5 hours later.
Can anyone who has been at it longer than me give me their routine that works? I just keep going low and dealing with it but I know there has to be a better way. Thanks for any insight.
