[Diabetes-Talk] Dexcom

[Jamie Gurganus]

Erica,

I love my Dexcom, and it does keep your A1C within a good range.  I don't
feel my low blood sugars, so my doctor insisted that I get one about three
years ago after passing out in the bathroom and suffering a serious
concussion and shoulder injury from the fall.  I have to thank Tom and this
site for telling me about the G5 mobile app for my phone.  Unless you have
some vision or sighted help in the home, the G4 is not accessible to the
blind.  I had to have my kids help me with the twice daily calibrations and
stopping and starting the sensor sessions.  So, if you do get one, get the
G5 system.  I can now do everything with the Dexcom on my own through my
iPhone, and I love the freedom and independence.  

				Jamie

Erica, 

A continuous glucose monitor (CGM) is a system that monitors your blood
sugar every minute then transmits the reading to your smartphone or other
receiver every five minutes. We on this list have found the Dexcom G5 Mobile
system to be the most accessible, but others are available on the market. 

Good question about pumps. Some pumps have a CGM built into them now. Some
Medtronic pumps have the Medtronic CGM built-in, and even use the CGM data
to suspend your basal delivery. Other pumps integrate the Dexcom G4 system,
like the Animas Vibe. But you don't have to have a pump to use a CGM. 

The Dexcom G5 Mobile continuous glucose monitor system (CGM) is worn for up
to 7 days at a time. It is completely waterproof and is intended to be kept
on when showering, swimming, etc. 

The system has no cords or tubes. It does not need to be recharged. 

A CGM sensor is first inserted just under the skin where it is held in place
with adhesive. The adhesive and sensor come all together as one piece so
there is no separate taping that is done, although it can take a while to
get the hang of how the sensor is inserted and getting the adhesive in place
without wrinkling. The part of the sensor that goes under the skin and stays
there for up to seven days is nearly as thin as a strand of hair and very
flexible. Very comfortable. 

The sensor and adhesive tape take up a space on your skin about the size of
three quarters (the coins), placed end to end. 

Then there is a transmitter piece that snaps onto the top of the sensor. The
transmitter is like a rectangular metal electronic device that is not even
as large as the sensor and adhesive, but it does stick up above the skin
about half an inch. 

The transmitter collects the blood glucose information from the sensor under
the skin every minute and sends it wirelessly via Bluetooth to a smart phone
like an iPhone every five minutes. 

Every seven days, you need to remove the old sensor, keep the transmitter
piece, put on a new sensor, and snap the transmitter back on the new sensor.


Using the smartphone app, you can always see what your current estimated
blood glucose is, and also the trend, e.g. it is rising or falling. 

The app in the smartphone also lets you customize when it alerts you if you
are going too high or too low. For example, it can alert you when you drop
below 80 mg/dl, for example, and when you go above 200, for example. 

Hope this helps,

Tom Ley
