Prediabetes "High" fasting levels, why and what to do now?

Mathilda Grace said:

Good Morning,

I'm a prediabetic (sort of) and manage my blood sugar levels by adjusting my diet an exercise.
Diet: vegetarian, almost vegan, lots of low carb soy yoghurt, nutbutters, nuts and veggies plus berries. Some beans, some cheese. No added sugar, no grains, no potatoes, no pasta, no bread.

My latest HbA1C: 5.0
So far, so good.
Due to the global pandemic I'm at home and due to another, non-diabetic-illness, I cannot work out at home or go outside at the moment. So no exercise.
I thought, this would be a perfect time to check my blood sugar levels systematically, as I now have a very structured and almost identical daily routine.

This is my system:

1. Fasting blood sugar
2. One hour after breakfast
3. Two hours after breakfast
4. Before lunch
5. One hour after lunch
6. Two hours after lunch
7. Before dinner
8. One hour after dinner
9. Two hours after dinner
+ additional tests if something is out of the ordinary

Now I noticed, that I have abnormally high fasting levels. Abnormally high for me, I might add.
My median is around 100 mg/dl.
I also never stray far away from that, as long as I eat my adjustet diet.
My highest blood sugar level was 139 md/dl after two hours of breakfast.
With one exception.

Yesterday at dinner I tested my reaction to pasta. So I ate 150g (measured dry) white pasta with a lovely tomato salad.
Before dinner: 101 mg/dl
One hour after dinner: 129 mg/dl
Two hours after dinner: 169 mg/dl
I wanted to know how long it took to get down under 140 mg/dl so I tested two times more.
Three hours after dinner: 149 mg/dl
Four hours after dinner: 136 mg/dl

This morning I had a fasting blood sugar of 102 mg/dl. So back to normal, I'd say.

I calculated my HbA1c from all of this and got 5.8. Whenever I get tested at my doctor, I have a fasting blood sugar of around 75 to 85 mg/dl and my HbA1c is a lot lower.

So my questions are:
1. Could my high fasting blood sugar be connected to me not being able to work out?
2. Is it ok to have quiet a low range of blood sugar levels when they are between 100 and 130 mg/dl or would it be better, if they dropped lower in the mornings?
3. Are high levels like the one after pasta ok from time to time? I eat carbs/sugar around 25 days per year. I walk them off at around 14 of them, so after two hours i usually am not above 140 mg/dl on those 14 days. Do these days have a negative impact on my overall health or are they ok?

Thanks so much for your information and to anyone who read through my ramblings.
I'm really grateful for this forum, it helped me not to feel alone with this.
