High Abdominal Circumference measurement - should I worry?

[londontj]

As my BMI is a bit high I'm being scanned regularly to check on the baby's growth. Am 32 weeks and she's measuring just above the 97th percentile for Abdominal Circumference. All other measurements are pretty much on the 50% line. I've had blood tests because of slightly raised glucose levels but the last one came back normal and am watching what I eat. Don't have an appointment with my midwife for another 2 weeks and just wondering if it's something I should worry about or not?

hi when did you have blood tests? if you haven't had a GTT test for gestational diabetes you should ask for one - not saying that you have anything wrong at all, but worth being checked out - your GP can arrange if you not seeing midwife this week. hope all goes well!

Thanks for the reply. I'm waiting for a GTT appointment to come through (expect it's stuck in the postal strikes) so hope it will clear things up a bit. Just looked at your GD thread and going to take on board the diet tips just in case...

I wouldn't worry too much. DS (now 3) always had higher Ab. circumference measurements and it was explained to me that it depends how much of the fluid is in their system at the time of the scan which can vary enormously, etc. He was a very very big baby no doubting but I didn't have gestational diabetes. This time round (carrying twins and being scanned fortnightly) both babies are always measuring small heads, large tummies, long legs (exactly same as DS) - all the sonographers have said it's fine. Seems to just be the way I make them!

Mine is like this too (50% for most then 97% for abdominal) but my BMI is on the low side. My m/w was not at all concerned by this pattern and said that the abdominal measurement can vary hugely in the same baby e.g. if the baby has swallowed a lot of fluid just before the scan. I'm sure the GTT test is a good idea but it could just be normal (I've not had the GTT test but my finger prick test showed blood sugar normal).

Hope all is OK for you too.

its absolutely true as well that some people just grow big babies! and theres nothing wrong with that its worth being tested just to put your mind at rest if nothing else... don't know about you but worrying seems to triple in pregnancy! I like having things ruled out...

I've just had a scan at 36 weeks and the abdominal measurement is 347.1mm and the head is 348.7mm both measurements are off the scale . I grow big headed, big stomached babies, my previous two dds were also similarly sized and were 7lb 12oz and 7lb 6oz so big abdomen/head does not equal big baby just a bobble head/beer belly baby!

I was being scanned regulalry with DS as i had uterine notching, an dhe too measured on the 98th percintile for abdominal circ, and on the 50th for eveything else. He was born absolutely fine though, well in porpotion and is now a strapping 17 month old.

Thanks all, very reassuring. Waiting for a GTT to rule out any problems but I slightly suspect she might just take after her parents (a bit round).
