I wonder if someone could advise me. I'm prediabetic and take my bloods occasionally. This morning my reading before breakfast was 6.6 and two hours later after a bowl of muesli and a cup of tea it was 4.6. I recently had my Hba1c test and it was 46. My blood seems worse after a night's sleep. Even if I've tested my blood 2 hours after dinner my morning test is often higher. Can anybody give me any advice?. After being diagnosed almost 4 years ago, I lost over a stone in weight and I swim 3 times a week (well, except for the lockdowns), plus I walk as much as I can. I'm reasonably fit.
 
Hello there.

You could be getting the classic "Dawn Phenomena" where the body or liver kindly dumps a load of glucose into your system as basically a get up and go or get you started for the day.

It happens too many people and is a natural thing, some diabetics can have issues with it, but at 6.6 it is within the normal range of things.
 
Try testing as soon as you wake up (put your kit by your bed) and see what it is then. The Dawn Phenomenon is a real nuisance. There’s also what I call a Waking Rise - that is, your body pumps out glucose as you get going and move around. That’s why I suggested testing the minute you wake.
 
It is actually perfectly normal for a non-diabetic's BG to increase by up to 2.8 mmol/L overnight, so personally I shouldn't worry about it, as long as it isn't a lot more than that. Of course, that assumes you had normal BG before bed, so 5-ish and max 2.8 higher when you awake.
 
Welcome to the forum @iprobinson

If it is Dawn Phenomenon some people find it can help to have a late night low carb snack with some protein and fat (eg an oat cracker with a chunk of cheese of some cold meats) can help to keep the liver happy overnight.

But either way your BG levels look pretty perky to me, and if you can keep those up I think you would see an HbA1c reduction 🙂
