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.

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.

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....

Hi Bambi: Every person with diabetes has these problems of controlling blood sugar. I also go up and down, and can get quite low. The Dexcom has made such a difference in my life! I love it. But, just reading over what you've told us, there are a couple of things I can see that would cause problems for me. If I eat something like French toast with whatever kind of syrup, I'm going to go high unless I really take extra insulin. I need about one unit for every twenty grams of carbs. Some people need more and some fewer unit. Cereal is loaded with carbs, and I have to do the same, take extra insulin. I went to a dietician years ago and she told me to always have a protein snack before bed, so I try to have something like cheese or an egg along with a very small serving of carbs before bed. I take my Lantus in the morning, not at night as many people do. Some people separate their Lantus, but that made no difference for me. I also try to keep the amount of my fast acting insulin (Humalog) at about the same number of units per day as my Lantus. (That is, unless I eat something very high in carbs and have to take extra Humalog. When I go high, I take a little insulin and I drink loads of water, which seems to help me get down. I set my Dexcom to alarm in an hour after I've treated a high, so I can see where it is now. If it is still high, it alarms. If it isn't, it doesn't. Some people with Type I really can keep their levels pretty steady. I've met some of these lucky folks. Some of them don't get it that not everyone can achieve that. However, that cereal you're eating might be a big problem for you. I'd try something else and see if it helps, and don't forget the protein. Protein helps your blood sugar stay more even. I don't know why, but it seems to do that. Good luck.

I understand this very difficult and you are all being very supportive. Andy I do go several hours without eating and I have such reactions to the insulin. Let me give you an example, breakfast wheat french toast w/sugar free syrup 3 unit SA Novolog, lunch Ramen noodle soup w/veggies 4 units LA Levemir & 3 SA Novolog snack mid aternoon will be under 90 for dinner. Tonight will be Shrimp risotto and salad with cereal before bed 4 SA will climb above 230 and crash below 80 in the night, some nights it's into the 40's and I've had my cereal at 11 PM. It's up and down really looking for how you experts that have been here longer have worked through your issues. I have only been diabetic for 3 years and have had epilepsy for the 10 years.

Comment by Andy on June 4, 2014 at 10:57am

Sounds like a fasting test would help get things settled. If you go without food for several hours while wearing the Dexcom, you can see if your sugars go up or down and adjust your long acting insulin accordingly. Pumps certainly make this a lot easier because you can set a schedule of insulin in case you need more in the morning to cover random dawn phenom spikes but less midday, especially if you are more active then.

If you are on Lantus, look up how people manage it with multiple Lantus injections. Instead of one large dose daily that may not necessarily be level the whole time, you might benefit from two or more smaller doses in the day as a way to adjust your "basal".

Comment by HPNpilot on June 4, 2014 at 10:43am

I have to say I don't understand this issue of having to eat to keep your BG up. If you have to do that, then your basal insulin is not correct. When your basal is adjusted properly, your BG should be stable (neither rising nor falling) without eating. Exercise, of course, would require a change.

Comment by Bambi on June 4, 2014 at 9:07am

I'm currently not on the pump we find it had to find a place to locate the unit I have now but my upper abdomen. PNB is a good suggestion but it spikes me and I crash like a rocket. I will try eating more often as this endo. so not so concerned with A1C as my last he felt I might see an increase wearing this unit but more stable numbers. My A1C with my last endo was 6 and he was not happy- I will be getting results my next visit from blood work by my GP.
Morning example French toast wheat, sugar free syrup BS 101 3 SA units soared to over 200 within 45 mins.
