My almost 13yo does Brazilian Jiu Jitsu 3x week. I would probably have to remove the CGM each time and replace after. That means 3 x a week we would have to replace it on him and use 3 every week. He was just diagnosed about 5 weeks ago. He has been getting a lot of lows right before bed. The lows range from 50-70. The lows have been really upsetting him as he feels sick to his stomach and gets weak legs. Last night he went from 69 to 52 in 10 minutes. I don't know how expensive the CGMs are and if insurance would pay for 3 per week.
