OGTT and HbA1c results interpretation

[ILovedSugar]

Hi all,

I really need your help interpreting my results. I will see a doctor as soon as it is possible but I just want to prepare myself for where I'm headed.

I was diagnosed with gestational diabetes with
Fasting: 5.5
1-Hour: 9.2
2-Hour: 9.1

I was diet and exercise controlled but was pretty low carb (below the recommended threshold).
I was ordered a postpartum OGTT 3-4 months after. Well it's been 4 months and I finally took the test.

My HbA1c is 5.0 % which I'm not surprised about as I went low carb post pregnancy.
However my OGTT are alarming:
Fasting: 5.33
1-Hour: 11.71
2-Hour: 7.6

The 1-Hour is obviously what's really alarming. I read that a reading over 11.1 at any point during the test is an automatic diagnosis for diabetes.

Is this what beginning of diabetes looks like? Or am I already diabetic? Is this prediabetes? I know the typical ranges of diagnoses but that fasting and 1-hour indicate a problem.

I'm pretty heartbroken right now as I was told that the gestational diabetes should go away after delivery.

Any input on this is very welcomed!

Edit: Just a bit about myself I'm 5'6 and 60kg. I'm not on keto diet but my carb intake is very low. All the carbs I get are from milk products, vegetables and nuts. My fasting numbers tend to be below 100 and in the 90s range. For some reason the diet did not improve them as it seems is the usual for those who go low carb. I'm not sure why.

No one here can diagnose- discuss the resin with your doctor. Be aware that low carb diets are not advised before oral glucose tests as the result is affected.

I have taken several GTTs, and only ever been tested at the start and at 2hrs.

my own prick tests during the 2hr period went over 15mmol/l (but it is several years ago, so memory may be dodgy). The last test gave a definite result of 11mmol/l at 2hrs and 10 mins (they were late taking the final test),

- and I was cheerfully told ‘you are pre-diabetic, not diabetic. Bye’.

You may find the following links interesting.

And
https://www.diabetes.co.uk/oral-glucose-tolerance-test.html
they both suggest that the diagnostic number is being over 11mmol/l at 2 hours.

being on a low carb way of eating may affect the result to some extent, but advice varies as to whether the patient is advised to ‘carb up’ for several days before the test, or not. According to a number of posts that I have read here on the forum, doctors and nurses seem to have different views on this, and give different instructions (or no instructions at all).
