Despite all the plusses of the CGMS, there are a few downsides.  CGMS cost around $1,000.  Sensors, which should be replaced every 3-7 days, cost about $50 each. Very few insurance companies cover CGMS for diabetics with good control, even though, as I myself have experienced, CGMS can be helpful for everyone with diabetes. Despite this, it's always worth talking to your doctor or diabetes educator about your options.

Also, although the entire system is as small as my pump canula, the sensor comes unstuck when I'm exercising. Although I'm experimenting with different kinds of tape, the sensor is still one more device attached to me. That being said, the positive sides of the CGMS far outweigh this inconvenience.

All in all, I love my CGMS. The short-term blood sugar patterns give me valuable information every day, while the long-term perspective gives me equally important data. The world of CGMS is expanding quickly; who knows what else technology will bring to diabetes care.
