Second GTT at 35 weeks after passing 28 week test-what next?

[KJM2013]

Hi
I had a routine GTT at 28 weeks (BMI of 31) and passed fine. However baby is measuring big after a growth scan that the midwife requested, so the doctor is sending me for another GTT. I will be 35 weeks when test is done and probably nearly 36 by the time someone discusses results. If I do now have GD (how likely is that after passing at 28 weeks?) what is likely to happen? Its surely too late to change my diet drastically, the baby is hardly going to shrink. I have an elective c section booked for 40 weeks after an emergency c section with my first (no GD in that pregnancy). Any thoughts/experiences gratefully received!

I don't know about whether they will be able to do anything while you are pregnant, it may influence induction though. An important thing to know is that if you do have it then the baby will need to have its levels checked after birth so it's important they know.

It depends. If you are diagnosed with GDM You’ll be asked to monitor your blood glucose levels and depending on how high they are you might be treated with oral metformin, insulin injections or a combination of both. You’ll most likely have weekly wellbeing/growth scans and will probably be advised to deliver earlier than 40 weeks, how early depends on how well your blood glucose is controlled and the results of the scans.
