For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (, which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

So how do you know when your transmitter is dying?

Comment by Clare on June 30, 2014 at 3:20pm

And to Isaac, I get my G4 belt cases from Tallygear, but there are also cases at I have a shapeways brixometer case attached to my bike handle bars to hold the receiver when I am riding.

The hourglass and the ??? are both system glucose errors. From the Dexcom users manual " These symbols mean the receiver does not understand the sensor signal temporarily. These symbols are related to the SENSOR only. Wait for more prompts, do not enter any blood glucose values when you see these symbols. Often the system can correct the problem and continue providing sensor glucose readings. If it has been at least 3 hours since your last sensor reading, contact technical support."

Just to confirm something: when you see the hourglass on the upper right corner, that means your receiver is dying, right? I have a new one, and I started it up, but just wanted to be sure.

Hey Issac, I get mine at and they have good items, materials and service. I suggest you look there as well as other places.

Above where you can read the comments there is a list of discussions. You can hit the "view all" icon and it will take you to all the discussions. There is a search place but it is really difficult to use because you have to pick out specific words in the title of the discussions.

Comment by Isaac on June 30, 2014 at 11:54am

Am I mistaken that at one time I could search within group discussion, but now I can't?

I am trying to find an old discussion here that Identified alternatives belt clip cases for the G4 receiver.

I remember there was a phone that was exactly the same size.

But can't figure how to search for it.

Hi pilot, That was one example of breakfast, I've tried eating omlets with veggies and wheat toast, scrambled eggs and a crumpet. I count carbs closely sometimes shooting low and still end up high then crash. I rocket down so fast my endo. want me on a high carb diet for weight gain. I only weight 100lbs and need to add pounds, I'm very watchful of the type of food I purchase all wheat products,organic produce, fresh fish and organic grass fed meats. I do choose Dreamfield's pasta which works for me as I've recently heard may no longer claim it's carb value but I do not spike on it as with other pasta's. I love pasta's mixed with anything veggies, seafood, meats, sauces of any type. I am truly finding this group so supportive I'm taking each comment listening.

Thank you Alex's good to hear from someone that has faced the ups and downs I'm really trying to balance All words of wisdom help, my new doctor is excellent and supportive. He put me on the Dexcom it has been a life saver I drop from 110 to 80 in a flash. I'll check before cooking dinner and within 5 min's it's on alarm. I normally need less insulin per carb. or I find myself so low at night. I'll try a high protein snack at night with a smaller carb load. I would just like to sleep through the night without the alarm going off below 80 and reaching for the glucose tabs.. It's very hard on my husband he travel corporate M-F and is frightened I'll have a seizure from a low. I have been experimenting with different meals to find ones that work better.

Food choice makes a BIG difference. There is no way I would eat a carby breakfast like that... I would be on a rollercoaster just like you. I eat a mostly protein and fat breakfast when I do eat breakfast (i.e bacon and eggs , etc , with maybe just a little fruit). Bread, cereal, etc are fast carbs and can causes a spike like that even with the correct insulin to carb ratio. While I am not on a true low carb diet, I usually eat no more than 130-140 grams a day of carbohydrate.

Are you counting carbs and have you tuned the ratios for different times of day ? That really helps prevent highs and lows....
