Depending on how much "real estate" you have and your preference for wearing the Dexcom on your arm, moving the infusion site to a different location is important. In my personal opinion BTW, scaring is minimal from the CGM being a fluid isn't administered. Dexcom G7 lasts 10 days and the 15 day wear G7 is supposed to be released later this year. Pumps and CGM's play better together when they are in direct "sight" of each other. It may be a challenge to keep the tubeless pump, considering site rotation, and CGM in the same area. With a tubed pump, one can move around the infusion set and still keep the pump itself in line of sight. Some thing to consider. I'm due for a new pump the end of next month and I'm staying with a tubed pump. Good you are asking questions. Good luck!
