A few questions if I may

[IanBish]

My first is relating to my CGM graph (below) which is where I ate some 10% Greek yoghurt followed by a small (sourdough) bacon sandwich. My question is why it stayed up for so long. I know there was a fair bit of fat in that meal. The lower line is 4, and the upper is 10 mmol/L.

My second is why do I feel a bit jittery and a bit lethargic when my BG is high (around 8-10)? I know I can feel a bit like that when it's low (below 4).

My third is what would be a rough equivalent of a CGM graph for a non-diabetic eating a similar meal?

Thanks in advance.

Was this your first meal of the day?
How does this pattern compare to other days?

I definitely start to feel lethargic when my bg gets close to 10.

It was the first meal, it usually is. I don't feel hungry till then. It's happened before at lunch with similar, high-carb meals. I feel fine once my blood sugar starts coming down, though.

If I may, a question back at you?

why do you feel...... Symptoms?

The answer to your first is, I would be guessing, but I think that it is your body's reaction to that food.
if you include, the insulin resistance etc.
The hyper is the sudden rise in by BG levels, by more than your body likes.
when you drop back down from your diabetic levels, hba1c levels when diagnosed, and have been in and around normal levels. Your brain notices this nd and may give you a warning that it doesn't like this sudden high.

Have seen so many graphs, that, it would remiss of me to interpret too much.
With the proviso that each one is different depending on what you have ate.

Symptoms are your brain, signalling around your organs, your gut, your enteric system, your nervous system, and everywhere else in giving a warning that something is not right.
The same when you feel pain.
The old joke about going the doctors.
I feel pain, when I do this.
Well, don't do it.

There is a thing called hypo awareness, after a while that you don't have a hypo.
In my experience, I get this. The series of my symptoms start with blurred vision, headache behind eyes, sweaty and so on.
I get a different series of symptoms when I trigger a reaction to carbs.
Hope this helps.

For me (as a T1 with some insulin resistance as far as I know), my first carbs of the day need a higher dose of insulin, independent of my morning rise.
No matter if my first meal is in the morning or late afternoon (my eating pattern is rather chaotic). So a slice of LC bread at 10 am needs the same amount of insulin as that same slice of bread at 4 pm if it's my first meal. But if I had a slice of bread at 10 am and a second one at 4 pm, I'd need way less insulin for that second slice.

You might be seeing something similar. If I weren't on insulin and seeing that graph, I'd be tempted to have a close to no carb breakfast and have the meal you described a couple of hours later to see how this changes things.

Thanks for your answers. They mostly make sense to me.

But I'm not sure what you mean by this.

I'm not hungry before lunch time, but I'll try what you suggested and see if it makes a difference.

Ian, have a look at this - it's a study of a small number of non-diabetic folks eating various types of meals while wearing a CGM. The basic demonstration is that BG quickly rises, as you'd expect, and then falls, also reasonably quickly.

Or you could eat a no/very low carb meal when you're hungry and have the bread type meal later when you're hungry again?
My post wasn't one trying to solve a problem, just what I would do out of curiousity to see if it would change the pattern.
I love those little experiments.

Thanks Kenny. I've seen that before but thanks for posting it again.

I will do. I may not do that today as it might interfere with my Friday night takeaway plans! Thanks.

If I eat something a bit carby, I will feel uncomfortably hot, tired and just "off". I have my main meal about lunchtime now, but late last night I had two slices of Bavarian ham. Not the most carby but enough for me to have a rise of blood sugar in the morning and make me feel sluggish.
