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

You are really getting overly hung up about this. Stop self diagnosing issues that are not there. 44 is low enough that basic lifestyle changes will usually reverse it, without need for constant if any bm readings.

Not true. Some people cant feel hypos.
I have been 1.4 before and didn’t feel it at all and yes it was double checked with a meter.

Totally agree with this , you don’t need to be monitoring blood sugars you are not diabetic . You would be better off working out how to reduce your HbA1C so that you don’t end up diabetic . Mine was 43 last August , I’m at risk as I take replacement steroids for Addisons disease , I went low carb in mid Sept 24 as I was diagnosed with NAFLD and it’s just been rechecked and is 38 .

Yes low carbing works very well; that's how I control mine.

Still don't see why OP can't use a monitor for a couple of weeks to see if she can gain any insight. If not, well, no harm done.

I agree- which can actually be a sign of the risk of developing diabetes in the future. Same as prediabetes. Does it run in your family out of interest?

3.5 is a normal blood sugar for someone without diabetes (and ok to drive if not diabetic!)

It probably has to do with insulin resistance which I am going to focus on now as I no longer want to be quite so strict with my carb intake!

But hypos in t2 when unmedicated are very unusual.

No diabetes in my family at all @Agiftandacurse although my older sister has recently been diagnosed with pre-diabetes too. She’s 15 years older than me and has been overweight and inactive most of her life with an ultra processed diet. Total opposite of me. No diabetes anywhere in parents or grandparents or anywhere.

Im treating this purely as an interesting bit of research to see how I react to certain foods. My diet is very limited due to autism/ARFID so any changes are going to be challenging. I will not eat rather than eat food I don’t like and often skip meals if I haven’t got the right combination of foods for that meal. I’ll see the GP at the end of the two weeks and see what she says. The advice was to see the HCA for dietary and lifestyle advice but I’m already doing everything anyway. I’ll also ask for my bloods to be redone in a couple of months. One raised HbA1c reading doesn’t seem enough to me. Two raised ones fair enough.
Id forgotten how AIBU can be 🤣

I read what you wrote.

How does a free trial alter the accuracy?

Where did she "artificially" produce blood sugar spikes? I seemed to have missed the post from OP saying she was injecting glucose. Note: eating food isn't artificial.

Your diet is almost certainly the issue. You say you are following the advice anyway but skipping meals and eating selective foods would not fall within their recommendations. Would it not be more productive to eat as you normally do and see the trends resulting from that? Is your regular diet balanced or carb/sugar heavy, do you drink enough water, is portion size an issue, are you overweight, do you exercise?

I’ve already said I’m not overweight (BMI 21/22) and am very active. I walk an average of 50 miles a week up and down big hills. I’m rarely still. I’m vegetarian and don’t eat ultra processed food usually. The Starbucks was not my normal diet, just an occasional thing. I drink lots of water each day as it’s my drink of choice. I don’t drink alcohol except some baileys at Christmas and maybe a glass of wine with Christmas dinner. I eat porridge with seeds for breakfast, hummus and breadsticks and veg sticks for lunch, or Greek yogurt and berries with seeds, snack on babybels and canteloupe, dinner varies but is made from scratch.

The dietician attached to the course is happy with my diet and exercise levels. The only thing she’s suggested is adding a little more protein, fat and vegetables to meals. Nothing major though. I need to prioritise better sleep and manage stress which isn’t easy.

Something is causing you to be insulin resistant. Unfortunately eating 'well' doesn't always prevent this and will still cause your blood glucose to stay too elevated for too long at times. I would suggest you look into that and see if you can make some changes.

Or it could be elevated stress levels which can add more points than you might think.

Yes just from your list there I would say you need to add more protein.

Nonsense. The Freestyle Libre 2 plus is what almost all people on insulin with T2 diabetes use to monitor their levels, and lots of people with T1 (some use a dexcom). The free trial is just than. One device for 15 days.
@LegoTherapywith an HbA1c at that level you would expect most of you glucose levels to be perfectly normal.
If you eat well and exercise, still take up what your GP has offered, you may learn something

Yes it's definitely worth remembering that prediabetes doesn't have to get worse by any means. It just usually does for a lot of people, some of whom may not even be aware until it becomes fully fledged T2.
