Both myself and my son are on insulin pumps. My son started on his when he was 11 and has now been on it for nearly 7yrs. He has never been bothered about it being fastened to him other than it is a psychological issue where he has a constant reminder of his diabetes, easier for a boy though as he can just stick it in his pocket. Contact sports and swimming are no problem as you can remove them for an hour without ill effects, there are also waterproof and impact proof aftermarket cases that the pump can be put in to protect them.
Most pumps are waterproof, so that shouldn’t be an issue
the minimed pumps are NOT guaranteed waterproof but there are numerous reports of them surviving water immersion. Canulas can fall out although this has only been an issue on holiday where a combination of high temperatures, sun cream and swimming pools have reduced the adhesiveness of the canula, between the 2 of us this has happened about a dozen times in the combined 15yrs we have been on pumps.
We both run near perfect Hba1c’s, we are able to exercise more freely than when on multiple injections, we can eat whatever we want whenever we want, only 1 injection every 3 days (canula change). neither of us would go back to injections and both feel that the pumps have given us a new lease of life. The only downside is as stated earlier, you have a 24/7 reminder of your diabetes as the pump is permanently attached, small price in my opinion for the improved control and reduced risk of the long term potential complications.
email is in my profile if there are any other questions you want to ask.
