Testing at 1 hour

Good morning!
After 2 hrs my readings are well down
with most of the meals I'm choosing so would it be ok to drop the testing at 1 hour or does the potentially very high spike matter a lot?
One meal in particular jumped from 6.1 to 11.3 at 1 hour but then down to 5.9 after two.

As a random BG of >11.1 is used as a diagnosis of T2 I'd look to reduce that 1 hour spike my reducing the carbs in your meal.
You are trying to limit long term complications & a non-diabetic would not spike that high even after a high carb meal.
What you have is dysfunction in your first phase insulin response even though your 2nd phase seems fine.

Have you considered a CGM, these are a game changer & you'd not have to prick at all.
 
Thank you. I am currently trialling a cgm but won't be able to afford to fund it myself after the final week is up. I'm learning from using it and it's much easier as I have very painful fingers but I will certainly continue to test at an hour given the information you have given me.
 
One thing I'm concerned about with the Libre is that readings don't tally with my Codefree. For instance my last reading at 2hrs was 4.2 on the cgm yet 5.7 on the Codefree
 
The results will almost never be the same. The Libre has both a time delay of about 15 minutes to a finger prick reading and it has an averaging effect.
Your Codefree reader probably has the standard error margins of +/-15% in the reading (the Libre also has error margins but I don't believe they are published?).
Edit: furthermore manual readings of the Libre are kind of momentary values or predictions. Your are probably better of using the 15 minute average value that will be on the graph later. If you want to know the exact 15 minute value you can use the libreview website and download the all readings file at the top right and open it in excel for example.
Edit 2: If you want to compare them, do so in a period that the Libre is showing little to no change and even then take into account the error margings (and delay).

Ah thanks so much for explaining that. It's all very interesting. I'm even more intrigued now.
 
I test at one hour as when I was pregnant last year the hospital told me to test at an hour and I had my lowest hba1c of 31. If I can avoid a spike at 1 hours it's unlikely to be a problem though some food like pizza do tend to rise later
 
From what I've read on the forum, the Libre is most accurate for levels between 4 and 9. When I was using the original Libre, I found that while it actually read 1-1.5 points lower than my glucose meter the actual patterns /trends I saw corresponded very closely. I used the Libre reader that came as part of my first sensor kit, and could scan the full 8 hours of graphs and upload them from the reader to Abbott's software on my PC.

Are you keeping a note/record of what's causing any high spikes at 1 hour ? Personally I'd definitely be avoiding anything that was causing them.
 
Thank you both. Yes I am keeping track of everything.
I tested porridge this morning which gave readings of 6.2 9.7 6.9 on the Libre. One of my favourite breakfasts but need to decide whether the 1hr spike is too high.
I am focusing on using that for the rest of the week as I only have it for a few days more.
 
Porridge and fruit for breakfast was the first thing my BG meter 'told me' to ditch.
Try eggs instead (or meat or fish or cheese) I found that gave a big fat zero BG response !
 
Thank you. I do enjoy eggs twice a week. I need to look at breakfast in general I think. The easiest thing for me would be to go without as I used to buy not sure if intermittent fasting is a good idea for diabetics as opinions seem to be divided. I shall read up more. Thanks again.
 
How do you get a cgm on a free trial?

There are many different types of diabetes all of them will require a different approach and fasting may not be ideal for some.
But for type 2's it is a very good idea, because we are resistant to our own insulin our pancreas is working overtime trying to make enough of the stuff to keep our blood sugars in range.
Fasting gives our pancreas a much needed rest and gives our body a chance to use up some of its stored glucose
