I typically find most coincidences hard to believe.
76 FDA approved supplements to the original G4 PMA in Oct 2012. Could any of the supplements have had a minor impact so as to reduce the lifespan of the sensor while not reducing it so far as to fall afoul of the FDA approved 7 day sensor wear?
I would consider it a possibility but no idea as to the probability of such.
i was hoping to get 2 weeks out of it like so many others i have read about.
I was just teasing you a little bit with that comment. There were times for me when the Dexcom started to get better and become more accurate and then it would fall off, and I kind of thought it was funny when it happened.
I donāt ever get 2 weeks out of a sensor.
why are we all so dramatically different? i know YDMV, but REALLYā¦
I have always wondered. I have read posting which seemed reliable that spoke of 45+ days.
There is speculation about the reasons for such a wide range of difference but I think nothing conclusive?
its amazing, isnt it!!
I calibrated this morning! - The dex (xdrip) read 5.3 (95.4) and the meter read 5.2 (93.6) so I thought it was time for a calibration as I probably had not calibrated for a week. Sensor is on day 12.
I generally calibrate probably twice a day on day 1-3 of a sensor. After that, I usually just calibrate only when there is a significant deviation between the measured BG and the sensor
After the first few days, I generally only calibrate first thing in the morning. Usually my BG is flat for a while at this time so I am guaranteed that the sensor and my blood sugar are in sync and I will get an accurate calibration.
Here is this morning showing the flat-ish line before calibratingā¦
For me the sensors fall off after 3-4 weeks. On average I pull them around 3 weeks. I find beyond three weeks I start to get some irritation around the sensor too and beyond about 4 weeks I start to see weird numbers from the dex.
I just started day 17 on my sensor when I read your commentā¦and 30 minutes later it started to tank! Just a coincidence, I know, butā¦ 
Iām using sensors that expired Mar 2018. On the last one now, all have lasted 2-3 weeks. Maybe my next one, not expired, from more recent batch will have shorter lifeā¦ not good.
Mine is the same way. I can get between 14 and 26 days on a single sensor, I think placement sometimes affects that. And I do the same thing. When my āSignal Lossā error keeps showing up and itās either in my pocket or on my desk or couch arm, itās time to change it.
Iām not sure Iām willing to go the G6 route until forced. Itās my understanding that the sensors cannot be restarted like the G5s, and that they are only good for a week (or was it ten days?).
G6 sensor is FDA approved and Dexcom intended for 10 days.
Didnāt take long for people to hack the process.
Directions for restart are available online.
We hope to be switched from the G5 to the G6 in a month.
i just want to put out there that i am LOVING my new Dexcom. i found a great sight on my upper left thigh and am having tremendous accuracy. its been a real help.
i am kind of ignoring the direction arrows b/c they seem to change from one direction to another from moment to moment, but if i look at the graph, i can get a really good idea of what direction i am going. and even if if lags for 15 minutes or so, its been spot on on many occasions.
YAY

Good good good.
BTW, i have often had to calibrate it twice a day, but not always. sometimes, i think,ifi am dropping or rising very fast, it doesnt have time to sync. not certain about that though.
Itās best to calibrate only when the graph is relatively flat and has been for a good hour, so the glucose in the blood and in the interstitial fluid have had time to settle at the same level.
thx for that. i think you have suggested this to me before, and i have been following your advice ever since. the mornings are best for me to calibrate, b/c i am most flat and consistent; yet sometimes i find a really wonky reading and have to wait for the dex to level off.
I also ignore the arrows. I like the Dexcom. But the algorithm they use to pick which arrow to display. Well. Nothing is perfect. I think that part of the algorithm is stupid. ha ha ha
I find eyeballing the graph is far superior to whatever the arrow seems to indicate.
I agreeāI find that I can get a horizontal arrow when my blood sugar is trending slowly but significantly downward, heading into a low. Also I can get a double arrow up right as itās clearly about to level off after a brief spike up, such as when Iāve just treated a low. Eyeballing the graph is usually superior to the arrow.
