The first worry I have is the CGM, before, during, and after any training or race I have too know exactly what my blood sugar reading is. I have used nothing but Medtronics pumps for the past eight years, I have also used the Medtronic CGM and must say I have a couple of problems with blood sugar accuracy. I strongly believe that the accuracy will improve with the 670G making the pump a great product for an athlete living with diabetes. What if the CGM reading is off though, what if I'm in the middle of a race or training run and my blood sugar is above my set range? Will I be given insulin while racing? If so what is that going to do to my body? I have been out of range during races and have never taken insulin because I know my blood sugar will get back in range as the race goes on.
On the other end what if my blood sugar is actually lower than the CGM reading and I'm unaware that my blood sugar is below the set range? Yes I know my body very very well when it comes to racing with diabetes, not all athletes do, it took me seven years to get to where I trust myself. I'm worried about the teenager that wants to become an endurance athlete and puts his life in the hands of this insulin pump. I believe in the pump don't get me wrong but things could still go wrong, as great as technology is things still don't work perfectly.
Technology is amazing but I strongly believe that as athletes living with diabetes we must know ourselves before putting our lives in the hands of any insulin pump. If we believe that an insulin pump is going to do everything for us then I believe we are in trouble when it comes to diabetes management. Much like a job you must know the basics before running a business or a piece of machinery. As I have said I love the direction that diabetes management is going but if we overlook all of the little things that come with diabetes we could put ourselves in danger as athletes living with diabetes.
