Which continuous monitor to get

[Rains]

I am considering getting a continuous monitor, but am not sure if one is more accurate or user friendly than the other. Does anyone have any information on how to make the decision. I would have to change pumps to get the Minimed. Any thoughts would be appreciated.

I am planning for pregnancy and have a good A1C, but I do have highs and lows, so my b.g. is not entirely stable. I have read the information that says no b.g. over 150 during pregnancy. I think the continuous monitor will help me see patterns and recognize that I am going high or low without having to test so much. Does anyone know if the CBGM will actually help with this?

Hi Rains,

Yes and no. My pregnant patients are all on a CGM if possible for the reasons you nicely explain and for the speed at which it helps the wearer spot problem foods that trigger postmeal spikes, and for quick corrections of basal and bolus doses during and after pregnancy where insulin need is constantly changing.

But all CGM devices have to be backed up with frequent fingersticks, especially during pregnancy. They are great for trends but can be off on accuracy. I would start on CGM ASAP to get some experience under your belt and to be as stable as possible before conception.

In terms of accuracy, Navigator is probably slightly better on acuracy but was only recently released and will not be available for delivery until about June. Dexcom is generally considered a close second primarily because it detects low readings faster and more consistently than the Paradigm RT, and lows are the major concern with the glucose targets you are aiming for.

All the best and keep us informed,
John

I have used the Dexcom Seven since it came out and is very accurate after the first day although you it gives you a good trend for the first 24 hours. The Medtronic Real-Time is terrible, I am wearing it now and I have gone low twice when it read 150 both times. My HMO pays for the Medtronic product but not the Dexcom but I will but the sensors myself ($240 for four). I have had these sensors last on average 14 to 17 days and had one last 23days!!!Just treat the one you are wearing like it’s a new sensor. It is very accurate and waterproof, plus a much smaller transmitter you have to wear. I can't believe the Medtronic senor passes the FDA. This is a VERY DANGEROUS device since you count on it to be accurate especially at night.
