Can I Think Of Fbg Of 103 As "normal"-even Though It Is 3 Points Above 100?

A DiabetesTeam Member asked a question 💭
Annapolis, MD

Today my fbg is 103-when I divided it by 18 it was 5.7. Since 5.7 is in a normal A1C range, why is the normal fbg range set at under 100? Nit picky-but I'm curious. I DO realize I need to continue lowering my numbers to a safer range though. My endo suggested I aim for 4.-but that is another story. :)

For someone diagnosed with prediabetes or diabetes any number below 7.0(126) is a great number @A DiabetesTeam Member, and @A DiabetesTeam Member, and @A DiabetesTeam Member, and all you warriors.

Non diabetic morning fasting blood glucose numbers are 5.5(99) or less.
I see you might have confused A1C numbers and British Commonwealth blood glucose numbers.

If 5.7(103) was your average blood glucose number, your A1C would be 5.2.

A 5.7 A1C converts to an average blood glucose number of 6.49(116.9).

That should alleviate some confusion.
Baby steps.

And never give up, never surrender, never ever.
You got this.
Have a wonderful day.

@A DiabetesTeam Member You're probably right. I am prone to obsess about nit-picky stuff- in order to avoid annoying stuff I NEED to be doing!! Time for me to put on my Nike's and just do it. (I have a pile of Medicare bills I just can't figure out-for the life of me).

Here is a chart I use to know where I am at, https://mymedicalscore.com/a1c-conversion-chart/
scroll down to find the color coded chart :

Left column is A1C chart in % value, not the same as our Can and UK blood sugar values. A1C is a % average value over a 90 day period of what your your average sugar levels were. Your red blood cells live 90 days so this is why people cannot cheat on an A1C blood test, as it is an average over the last 90 day. So even if you studied hard for your A1C (by really watching what you ate for lets say a few weeks prior to testing), your A1C shows the whole 90 days value, so cheating as per say is impossible. I know some countries also have a different way of calculating A1C.

The next 2 columns are :

Middle column is USA blood sugar values in mg/dL

3rd Column is what Can and UK uses for blood sugar values in mmol/L

So depending which country you live in you can look up your A1C and it will give you your average sugar levels on your red blood cells the past 90 days.

Now on the chart that is color coded, green is non diabetic values, but it is also a safe zone for diabetics and what you need to aim for to manage your diabetes.

Green zone = A1C of 4.0 % to 5.6 %, find the column your country uses and that is where you have to aim for, this is also an average number over 90 day period, so trying to keep your average daily number in this range is good.

Yellow zone : Pre Diabetes = A1C of 5.7 % to 6.4 % again look up the column your country uses.

Pink zone : Diabetes 6.5 % to 10 % This is the zone where many get diagnosed diabetic

Red Zone : Danger zone which you never want to reach as a diabetic.

So the safest is to keep your A1C below 6.5 %, some doctors depending on your age and other health related conditions will only treat with medications if you reach A1C 7 %.

Just remember an A1C of 6.5 % and above means permanent damages to your vessels and organs, hence why it is best to remain below 6.5 %

Therefore if you try and keep your 2 hrs post meals blood sugar below Can and UK 7.8 (USA 140), this keeps you in the safe zones. Your 2 hrs post meal should be your highest blood sugar value, so to test this, check sugar level before the first bite and then exactly 2 hrs post 1st bite, this will allow you to tell if what you are eating is safe for you, sometimes if not just reduce portions or do not eat the culprit food, try combining with something else to see if same happens.

Hope this helps, 1 day at a time
