[sayanaarun]

Dear all

I am 25 yrs old. And i had diabetes on previous pregnancy. And had a preterm delvry 3 months before. Now

My hba1c test result is mormal 5.3%

fasting blood sugar is 87

and the glucose tolerance test with 75 gm glucose aftr 1hour 168 and urine sugar nil

Aftr 2hr 161, urine sugar is nil

Repeat post meal test twice with gap of few days and see If BS still remains elevated.

Reason for low Hba1c could be that you BS has started rising recently. Some variations in RBCs will show falsely higher or lower Hba1c values.

she is prediabetic. There is a separate entity called diabetes of pregnancy - induced by stress. She is likely to develop D in future. She must control her diet.

there are people who show abnormal glucose tolerance under stress. They have normal glucose tolerance otherwise.

Many ladies show abnormal glucose tolerance during pregnancy and once pregnancy is over they show normal reports. So there is an entity called D in pregnancy. These ladies develop D later on in their lives. Whatever name You can give to this condition preD, latent D or any other name but they have a strong tendency to develop D.

Yes. I'm talking about GD.

So what term would you like to use for it? After all it's a kind of D.

Anup

"Prediabetes is a fancy term.

Diabetes is like pregnancy

It's either a Yes or a No"

so not simple y or n. Can GD be said 1.5?

HbA1c is not to read BS. It is only to read the aftereffect of elevated BS levels over the previous 3-4 months. Correlating HbA1c to BS is nothing better than a "crude approximation". There are more than one calculation to relate HbA1c to BS (eaG). Each one give a different value of eaG for same HbA1c. This is because the formulae are empirical, dependent on the BS data/status of the sample population of diabetics of the exercise/study.

Fasting blood glucose of 87 is borderline. And the fact that you had diabetes in pregnancy could mean that you are beginning to decompensate. This is a warning sign, check your diet.
