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

Members: 223
Latest Activity: Dec 14

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.

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

82% time in range

Anytime I can spend over 80% of my time in range with zero hypos, that's a great day. I put a new pump into service so there's an additional 21 grams of carbs at noon.

With a standard deviation of 28 and an average of 114 mg/dl, this day meets 3 of 4 goals for me.

@AR - I've changed my policy on using CGM data many times. I especially find it hard to wake up enough to finger-stick when I'm sleeping. If I know my CGM has been correlating well then I'm more likely to trust it.

You're right, of course. When BGs change rapidly, using a CGM reading to add insulin or food can mean trouble. I've learned this. more than once, the hard way. The CGM lag, however, was not the problem the other night. It was simply a hard-charging low with a lot more power behind it than usual. That, compounded with my restraint in over-treating the low and sleeping led to the long, long hyper event.

@Ralph - regarding your insulin dosing to cover the protein late evening low-carb meals. I suggest, instead of giving yourself 2 units of rapid-acting insulin, why not try 2 units of NPH? NPH onset, peak, and duration are longer than rapid-acting but may match your nutrition profile better. NPH is an older formulation that had its own collection of troubles but may be just the tool that you need for small doses in specific circumstances.

Since I use a pump, in your scenario, I would give an extended bolus over two hours to to cover a similar snack.

12 hour 71-123 oasis

After wild swinging BGs the last few days, this was a welcome groove. Not flat, but welcome nonetheless.

I pretty much always test for lows, because of the "lag" time. Even if the sensors, and I'm using Enlites, are pretty flat, sometimes a reading of 70 can correlate to a 50 or 55 or something. Not a huge deal but I would treat a 50 a bit more aggressively than a 70.

Thanks for sharing the non-flat Terry! I've been having DP mayhem for what seems like months now, maybe since I stopped running a lot when I sprained my knee in early October. I don't usually run in the AM (AM is for lifting...which can also be problematic....) but I only seem to be able to get a 12 hour line as the 24s always have some bumps. I still don't trust my Bayer Meter enough either. I think it reads a shade higher than the One Touch UltraMini it replaced which, in turn, leads to more corrections? Maybe it's more accurate but my A1Cs have been pretty low (2x 5.0 in a row...) despite my perception that my BG is "always" high these days?

I had an encounter with the TSlim guy and was very impressed but then a week or two later the Vibe announcement came. Maybe it's time for a change?

Re circadian issues, I've only been able to string together 3-4 days of flatlines before I get a huge DP blowup. Sometimes, by "huge blowup" I mean 130-140 but still....

The 24-hour echo effect

Even with a different set of inputs (meal and insulin dose leading up to the "echo day") the BG line seems to want to retrace the aberration of 24 hours ago. Note the 2:00 a.m. dive and the 5:30 a.m. peak.

I've noticed this over the years. My metabolism seems to want to revisit in circadian fashion what happened 24 hours ago, even it's a totally dysfunctional trace. It's a metabolic echo.

Thanks for the comment, Clare. I'll trust the Dex when I know it's correlating well with fingersticks. The 51 fingerstick around 3 a.m. with the Dex at 55 showed that to be true. Your idea to respond to the second Dex low alarm with toast and peanut would have been a great move looking back, but I fear not a very good move for most of my lows.

Today is much better, but I observe a moderate "BG echo profile" that retraces, in a much milder form, the drastic down, up and slow down of the previous 24 hours. But I'm 80% in range, with only 2% hypo (2 readings @ 64), a 107 average and a standard deviation of 29. That's 4/4 of my daily goals.

Wow Terry I'm glad I'm not the only one :) Do you always trust Dex for lows ? As a general rule I check and make sure Dex is accurate. Your treatment initially should have been adequate especially the almond butter for the slow burn. I have no idea why it wasn't sufficient but if it were me, the second time Dex woke me up I would get out of bed and make a piece of toast with some peanut or almond butter or something instead of the fast acting glucose tablets which are good for a temporary fix but don't have any staying power. It's so easy to over treat a low. In fact that is why I turn Dex off sometimes when it is nagging about a low. I know the anxiety it causes will prompt me to overtreat and end up skyrocketing later on. Hope today is better for you.

Keeping it real

I sometimes worry that the casual visitor here might conclude that flatliner posters don't have the same challenges as others with diabetes. That we are able to produce flatlines every day. This post should help put that idea to rest.

Just after midnight, around 12:30 a.m. yesterday, my Dex woke me up with a 70 alarm. At that point I had about 0.4 units insulin on board from 9:40 p.m. bolus of 1.35 units. I ate two glucose tablets and a teaspoon of almond butter and went back to sleep. One of the things that often throws off my control is overt-treating lows. I thought this low counteraction was just right.

At 1:30 a.m. my Dex wakes me up again and shows my BG at 53. So I eat two more glucose tabs and roll over.

At 2:35 a.m. the Dex is nagging again and shows a 55. I eat two more glucose tabs and roll over once more.

Finally at 2:50 a.m. the Dex tells me that my glucose level is still in the mid 50s. I get up and do a fingerstick - 51.

I know how this story will go but there's nothing I can do now but treat the low. I have one tablespoon of maples syrup and go back to bed.

As you can see, the pent up counter-regulatory systems shoots be into a sub-orbital hyper that tops out at 330. I got up around 7 a.m. at 290. Ugh! I drink a large cup of water.

From experience I know that I am now sentenced to many hours of hyperglycemia that I can do nothing about. I know that adding insulin will have little effect but I add 3.3 units correction anyway. In fact, adding to much insulin to correct will most likely end up in a roller-caster. I also know that eating will just makes things worse. I know I'll fast until dinner time.

So, at 9:30 a.m. I go out for a 2.5 mile walk with hope that I can break down some of the insulin resistance. It helps some as I start out at 260 and see a 233 at 10:15 a.m. I walk for another mile at 1:15 and my BG goes up from 211 to 223.

I get back into my target range at 6:37 p.m., an ugly 15-hour hyperglycemia episode. I finally enjoyed first meal of the day at 6:45 p.m.

This was a hard driving low fueled from an unknown source. My low treatments were adequate, I thought, but I obviously needed much more aggressive treatment earlier. What held me back from that path were all the times that I over-treated a low and ended up high again. The only thing I can conclude from this event was that I have type I diabetes!

I now have a new policy. When I go below 70 between 11 p.m. and 3 a.m. then I will get up, treat the low, and stay up until my BG safely rises above 80.

Ralph - Are you using the Libre system continuously or did you run out of sensors? I'd love to see another AGP chart.
