My Glucose Sensor

I have received my new glucose sensor.  It is the Dexcom7.  I have been wearing a loaner for the last four weeks and I believe it is helpful.  In a short time my A1c lowered back in to the 6 range and I had gone up into the 7 range for the only the second time in 30 years.  I was reluctant to have a second device stuck into me but it is something to which you can accommodate. It is very useful to show the direction that your blood sugar is going, especially when you exercise.  The alarms make the nighttime safer.  At first there were too many alarms.  There is an alarm for being out of range which was going off all the time at night.  The first night really got on my nerves.  Michelle Cordell, CDE and RD who has had Diabetes longer than me is quite expert with this thing and showed me how to regard the differences between my meter reading and the reading on the sensor.  Trends are the important information that you will have.  The graph of your every 5 minute reading and the arrows that indicate rate of change make it less likely that you will chase high blood sugars or over treat lows.  Understanding that the reading comes from an algorithm applied to sugar in the tissue fluid and not the blood explains the delays if your blood sugar is rapidly changing.  When things are stable the Dexcom  can be right on or only a few off.  You still have to stick your finger at least twice in 24 hours to calibrate.  By the way, the number of finger sticks do go down a lot.  Michelle has gotten her A1c down to the high fives.  Of course she is an expert at all the dietary stuff.  Jody is also a trainer on the Medtronic sensor.  A new one is supposed to be out soon.  I hope they are able to marry the pump and the sensor someday so only one thing is stuck in and the day of an artificial pancreas comes.  We hope that our health will be good to take advantage of these developments.
