A club to share your successful and not so successful trends (graphs) from your CGM or Glucose Meters....

Members: 213
Latest Activity: Jul 17

The most elite Diabetes club on the net ;)

Below you will find FIVE different discussions to chose from to post your trends (Please do not post them on the main page)....


1. Flatline 12-24 hours (trends that you are proud to share).


2. Flatline 1-11 hours (trends that you are proud to share)


3. Rocky Mountains (low and high blood sugar peaks).- Days where we have very low blood sugars and the highest of high blood sugar peaks.


4. Rollercoaster- "lines that aren't flatlines, but aren't exactly Himalayas/Rocky mountains either" this is the in between area


5. What in the World? This is the area for those things that just are'nt right with your CgM trends.


Post your trends, don't be bashful. There's not many things better in a diabetics life than discussing glucose trends (good or bad) with other diabetics. Remember, the bottom line is this group is for support, not in anyway a competition.

The below 24 hr trend is from Nate, a 15 year old type 1 Diabetic... with a little help from his mom Emily, they are achieving some of the most inspiring trends to date. A 15 year old producing 24 hr Flatlines??? wow! Need I say more?"WOW, a little…Continue

Kate, AKA Queen of the 1-11 hour Flatline area strikes again. She has managed to pull off a perfectly level 3 hour Flatline this time.... not an easy task to achieve. Good morning Sunshine indeed!Reply by Kate on May 24, 2011 at 4:44am"Good Morning,…Continue

70-140 Range 11/14/2010 I had friends and family over and went a little crazy. I'm human! Does it look more like the Himalayas or Rocky Mountains? Hmm..  Post your not so flatline (low and high peaks) like photo's within this discussion. I…Continue

So, there has to be a category for lines that aren't flatlines, but aren't exactly Himalayas either. I thought, maybe, Appalachians, but I'm not sure if I'm even spelling the word correctly. How about just, 'Rollecoasters". Here's my attempt to…Continue

What in the world??

This is the area for those things that just are'nt right. For instance from yesterday to today my Dexcom sensor has been off. If I fingerstick 100 the Dex says 180, if Im 150 the Dex says 260! So, the PG expression is "what in the world?" Normally,…Continue

I have estimated my SD for some time. My experience is that my blood sugar does not behave properly to be characterized with SD. I tend to have "outliers." I will have 90% of my readings be in a tight range and then some "real doozies." This means that calculating SD over a short time period (with few samples) can be markedly influenced by a single bad reading, but that over a longer period of time those outliers have less influence on SD because of the larger number of samples. Bottom line, you can't compare the SD of the MM and Dex over the same time span, the number of samples significantly affects the SD estimate.

Thank y'all for your explanations. Now it makes sense.
Onesaint, I couldn't find any pinhole in my computer, and I think they'll have to take it apart so going to the shop today. Gotta pay for stupidity, ya know! :-(

Helmut, the idea of non-diabetic, typical Type 2 and typical Type 1 cracked me up! As if anyone on this list is typical! Maybe we were all Type 2's and didn't know it before we got our CGMs?

So I went home and downloaded the Dex and the MM to see what they said. The MM had a grand total of 103 readings over the last 14 days (wow really??). The Std. Dev. or SD was 29.

The Dex has 2,707 readings over the last 2 weeks (again wow really??) with an SD of 22. Thats a drop of 25% of the total MM SD. So, it seems SD can be widely effected by # of readings. Interestingly enough, the MM avg BG was lower than the Dex's.

SD 10-15: Non-diabetic
SD 20-30: Typical T2
SD 50-60: Typical T1
Before dex my SD was in the typical T1 range. Now it is in the typical T2 range.

I have seen a bunch of people say that they could not delete readings and I would hate that. AccuChek spoiled me!

I try to test about once every hour - sometimes more if I am low but the Dex does the rest. Since I am using the Dex, I rarely look at the SD number in the AccuChek software since I know the Dex has more readings.

Yes, it is the whole point behind flatlining!
Comment by onesaint on April 7, 2011 at 6:44pm
Oh thats brilliant Kelly! I wish I could delete reading on the MM meter. I really dislike when I have an off reading due to dirt or water on my fingers.

Plus I tests for highs, lows and meals only, the rest of the time its the Dex at work. The more readings you have closer to the target would make the average closer and thus effect the SD.

I will say I think the theroy behind SD is what I strive for in my management style and is the whole point of flatlinning isnt it? =^)
Comment by Kelly WPA on April 7, 2011 at 6:33pm
Onesaint, I agree that there are variables that you have to look at. My testing 18 times a day is going to have a more “realistic” number than someone only testing only before meals. My Dexcom has a more realistic number than my meter because it checks every 5 minutes (as long as I don’t have an out-of-whack sensor).

One thing I really like about my Aviva meter is I can delete readings – the ones with something on my fingers, I try to delete because that throws my number off. If it is a true high, I don’t.

Standard deviation (SD) is something all diabetics should watch very closely. I was getting close to a SD of 2o while using my Dexcom, but now I have moved away from that target since my insurance is no longer covering my Dex.
Comment by onesaint on April 7, 2011 at 6:28pm
Oh, disc out. You say its a mac? There is a pin hole depending on the model. put a paper clip in the pin hole and the CD opens up. Sim, Sim, Salabim!!
Comment by onesaint on April 7, 2011 at 6:26pm
Standard Deviation is supposed to be the measure of variability of your BGs. It essentially takes the average and shows the average points you move one way or the other from that average. From Wikipedia:
A low standard deviation indicates that the data points tend to be very close to the mean, whereas high standard deviation indicates that the data are spread out over a large range of values.
As for what it should be, well it depends on how many readings you have, weather those readings are high or low tests only, and other variables I suppose. I tend to take it with a grain of salt as I think it can be erratic based on my tests (what happens if I have sugar on my fingers and that test is taken into account?). But for PWD as I understand it, the lower the better.
