Supersapiens - continuous blood glucose monitoring

From the diabetes.org.uk web site Driving and diabetes

“Five to drive – your blood sugars have to be 5mmol/l or above before you drive. If they’re between 4mmol/l and 5mmol/l, eat some carbs before heading out.”

“These rules are only about checking for low blood sugar levels – the DVLA don’t have any specific limits on high blood sugar levels.”

I belive, that it can line you up with being charged as “driving under the influence of drugs”, which is fair enough really, what’s the difference of being drunk/having a hypo (T1 living in the uk)

But can you imagine the backlash if a hypo driver ploughed into a group of children?

I’m surprised that there isn’t something like that in the US.

Though as I don’t live there it makes no difference to me, though it may do to others…

Edit - Random Internet search suggests its state dependant…

But if you’re hypo and cause a crash they can take your licence off you.
I believe you also have to tell the DVLA how often you’re hypo and you get a shorter duration licence than the normal population.

Think this is the case…

Edit here’s the info…

From the same site you linked to. :grin: :+1:t2:

What are you butting me about ???

Ha ha, you’re taking that out of context. :grin:

I’m not butting you… Personally.

Ah sorry, you made it sound like I said something wrong, I just didn’t lay out all the rules about being diabetic and driving (left that to the link) as thats not what they were talking about …

No, not at all.

Well, you don’t need to be worried because we weren’t talking about blood sugar levels. We were talking about hgba1c levels so you were arguing with yourself lol :joy:

Then that’s more worrying as that’s a readjng of the last three months average. So super tight control but every time he’s been over he’s also been under to balance it out.

Not arguing just commenting on a post. :grin:

Not exactly. There is instrument variation, along with population variation so each lab establishes their normal reference ranges for a given population. You’ll see some variation in the decimal point range or no variation. In general 4.0 to 5.4 is considered normal and is effectively normal as far as health outcomes go. This individual is in the 4.3 hgba1c range with some ± which is incredibly good considering how hard it is for a type 1 individual. Even the glucose readings by finger stick and cgm has a ± 10 to 20%. If you wish to interpret the data correctly you’ll have to account for that and factor relative values into account because absolute values may never be that precise.

I agree. It’s important as it is basically a dui. Unfortunately, the scenario you mentioned is basically everyday here in the usa, minus the hypo stipulation. So yes, there would be way more backlash to that regulation being added than kids getting run over. :man_facepalming:

I’m not really understanding optimum levels for us folk here.

More often than not, our levels will be elevated as a result of high workout intake, pre and post workout supply, and then recovery mode where elevated cortisol is likely to result in higher resting levels.

Am i making sense here? I do see both variations. When I’m training a lot, or experiencing high volume and thus body stressors with often lots of daily fuelling, highish levels. I do see though my fasting levels be about the recommended normal. But this takes a while. I do high volume (800 - 1000 tss per week), so this is somewhat expected, right?

Interesting it’s now got a Connect IQ app for Garmin. So now I’m interested.

Can it tell you when your energy is about to dip and therefore power will begin to drop?

This is not so straightforward to gauge for the reason that activity level and intensity, say an interval or rest phase, will also change the monitoring level. Going for a walk simply can bring it up but then quickly down, so the temporal change is rather hard to understand at first. However, it can help you in this direction. I used it for my morning workout to gauge how much some of SS work needs.

Picture below shows how it looks on an edge 530.

My Brother in law uses the G6 and he says there is no delay either.

Thanks @admigo really appreciate an actual pic too.

What do you think about long sustained efforts, like 1hr + efforts where you want to keep an almost constant power and consistent stream of fuel intake - do you think it would helpful to show if you fuelling strategy for that is falling apart and you maybe need to up the intake, or even ease off the intake as you’re well loaded for the time being?

That’s absolutely the use case. Being able to see your levels and the trend rather than guessing or just blindly fuelling. Also helps to experiement with different fuel sources and your reaction to them - for example taking a gel that spikes your levels causing an insulin response that then actually inhibits fat oxidation.

In that case this makes it super interesting. I have to try this. The trial pack will last 2 weeks… do you think one sensor might be able to last a bit longer than that? What’s the deal with the shelf life on this thing?

Basically I’d need to pick out a 2 week period over the summer and run smash fests, long multi hour tempo and sweet spot and threshold efforts. Could learn a lot I’m thinking here. Just wish they could get the price down a bit, can’t see me paying this much all summer unless it really helps me smash long sustained rides in a way I haven’t managed to before (which could be the case, I very often under and over cook efforts by being too wary of my fuelling or not fuelling enough).

UPDATE: Looks like you can now order a trial pack of just one sensor, it was previously a pack of two. Each sensor will last 14 days from when it is activated, this can not be extend. The app works on both iPhone and Android but check the device compatability. Initialisation is done via NFC, data from then on is streamed via Bluetooth if the phone is in range or can be manually scanned once back near the phone (again uses NFC for that). The sensors I have in desk at the moment expire March 2022, so there is a shelf life, but it isn’t too short. You need to be careful with the sensor, if you knock it off inside the 14 days you are hosed - it can’t be re-applied - you just have to remember you have it on. There’s a super helpful facebook group you probably want to join.

One thing to note on the Garmin integration - right now it requires your phone to bridge between the sensor and the Garmin device - so you have to have your phone with you. Also the glucose level is NOT written to the activity file, so don’t expect to find the data if you export the workout event to a .FIT file.
