Any diabetic nurses or GPs about? Pre-diabetes and continuous glucose monitor showing little variation

[LegoTherapy]

I’ve been diagnosed with pre-diabetes. I’m not overweight and eating healthily and am very active every day, except the odd Sunday.
Out of curiosity I signed up for the two week trial of a continuous glucose monitor to see if I could pinpoint what foods spike my blood sugar. Nothing spikes it. The highest it’s been was 8.1 after a fig roll and was down again within a few minutes. After meals it goes to around 6-6.6 then comes back down quickly. I’ve had quite a lot of readings under 4 but felt fine. I’m wondering why my HbA1c showed prediabetes yet I’m not getting any spikes. Today is much like any other in terms of readings and looks like the attached. I’ve challenged my body by eating and drinking high carb/sugar foods and it refuses to get excited and keeps things steady.
It’s really interesting and I love numbers (autism) so this is fun to do for me but can anybody help me make sense of it please?
Obviously shamelessly posting for traffic

This was mine last August when I was diagnosed with T2 diabetes. I had apparently had it for a while which makes sense, I have had insulin resistant PCOS since puberty, got GD when pregnant with DD and had been feeling ill for months before my diagnosis. I suspected Diabetes but couldn’t get a doctors appt so bought a Freestyle Libre sensor on Amazon and when I started getting these results I called 111 for advice, the Dr who called me back sent me to A&E and they started me immediately on insulin.

The OP is NOT diabetic 🙄

@Notouchingmybhunabut the OP is pre-diabetic and has been advised to adapt their diet to reduce their blood glucose levels. A CGM is a valuable tool in understanding which foods are causing excess glucose levels.

We do not all react in the same way to the same foods. For example I cannot eat potatoes, they spike my sugar levels very high and it takes hours to come back into range, I can eat oats and I can eat a small amount of basmati rice but not long grain.

Libres are pretty accurate to be fair, not sure how a free trial makes it unaccurate?

Has the OP bern advised by an HCP to sign up to a free trial of a monitor and to artificially manipulate their normal diet to try and induce spikes?

@Notouchingmybhunawhat's your point?

@InfoSecInTheCitywow, that’s the kind of spikes I was expecting although at lower levels. This is today’s graph. The lows overnight I think are due to me lying on that side which can cause false lows according to the instruction/care book. The other lows are when I’ve been up and about walking or just going about my day to day stuff. I’ve changed the upper range now to 7.8

Problem is this just one day graph? (Sorry if you posted more) your A1c is measured over a period of 3 months. Anyone can have a good day with blood sugars (even diabetics do!) but doesnt mean the next day will be as good.
Have you done any excerise today? Or upped your excerise at all?

I@NotouchingmybhunaI’m not artificially manipulating my diet. That is my normal diet on a trip to the nearest city. Since diagnosis I wouldn’t usually have those things but wanted to see how my body reacted. You seem to be very offended by my thread so perhaps it’s not the thread for you.

@GoodnessGraciousMeUhOhall days look the same. I do the same amount of exercise each day, more or less, and eat the same things most days except for the Starbucks and bubble tea experiment. I don’t have those regularly.

‘I only started the course a few days ago and have deliberately challenged my body with cake and a caramel Frappuccino along with going out for pizza and pudding’ 😉

Libres can lag and they also are confused by blood sugar going high or dropping quickly. As a type 1 diabetic I find it to be great for patterns but I always check with a finger pick if it is suggesting something different to how I feel.

Your graph looks enviable! For blood sugar it is activity rather than exercise so that could have led to less pronounced spikes if you were up and about after eating. You don’t need to be taking rigorous exercise for it to impact blood sugar levels.

@Notouchingmybhuna actually its a good idea to try these things to see how they effect your BS. Why are you being weird about it?

FGS what is your problem?

leave the OP alone. You are willfully 'misunderstanding' & twisting her posts. I don't know what your angie is, but give it up!

FGS leave OP alone - she's trying to see how various ways of eating might affect her blood sugars. I don't see why you have such a big problem with that. Seriously what is your issue??

Haha X post.

Seriously weird as I'm glad others have picked up on too.

What are you talking about? Offering someone a trial of something does not alter the accuracy of said thing.

Sorry @LegoTherapy I've no experience myself but my DD is T1 and she finds there is a great variance between the sensor and fingerprick. They measure different things.

I'm T2 (also healthy weight and eat well/keep fit) but don't use the sensor although I might try it at some point.

I'd test all your carbs and starchy veg to see which you can tolerate better, and possibly also ratios of carb/fat/fibre/protein to see what's optimal for you.

Also @LegoTherapy there's a diabetes topic here and it may be an idea to have your thread moved by MNHQ so that you will get answers that are more likely to benefit you.

Re read what I wrote. See also ‘genetic tests’, ‘food allergy tests’ and the rapidly emerging and very lucrative ‘home testing’ industry.

The OP is NOT diabetic. She does not have abnormal blood sugars. Trying to artificially produce blood sugar spikes is the weird thing here 😉

I am diabetic and use cgm. It's not as accurate as doing finger pricks. If I'm bouncing along between 5 mMol and 8mMol I don't bother, but outside this range I finger prick to double check and can find the reading I'm getting on the cgm is not particularly accurate.

Do you also realise OP, that if your reading is below 4 then you shouldn't be driving until you've double checked with a finger prick?

I do agree with @NoChristmasGooseForYou. I use a dexcom G6 and some sensors can be off! I had one last week that was reading 5-6 points off had to take it off after a few days. Get a glucometer as well.

I’m about 1.5 hours after my dinner of wholewheat pasta, homemade tomato sauce, mushrooms, red peppers, broccoli and mozzarella. I feel fine 🤷🏼‍♀️ it soon bounces up again but I’m intrigued why it’s low so often. I’m rarely still after meals.

FIVE TO DRIVE! That’s all I remember from my diabetes training years ago. Many years ago. CGMs weren’t a thing. It’s ok, I don’t drive. I walk everywhere.

If you were really at 3.5 you would feel it.

Yes it's clearly not correct. You might just have a dodgy one, I guess.

It’s back up to 5.6 now. Weird. It’s never low for longer than a few minutes. My worry is that my pancreas is pumping out too much insulin to deal with food. A bit of a trigger happy pancreas.
