20 weeks scan - small head and huge tummy. Problem?

[neolara]

I've just had my 20 week scan. Apparantly my baby's head measurements are around or just below the 3rd centile but the tummy is huge. All other measurements are average. As a result the hosptial want to rescan me in two weeks to check the babies head is growing. They didn't seem too concerned but I wondered if anyone else has had this and what the outcome was.

Ummm, not sure whether this will help you, but at my 20 week scan, the baby was fully in proportion, but at my 28 week scan, head and legs were still in proportion but stomach was much bigger.

On the same day, I had to have a Glucose Tolerance Test (because my Mum has type 2 diabetes - no other reason than that) and it came back positive.

Apparently the diabetes can cause the baby's stomach to get bigger because your own insulin doesn't filter out the sugar so it goes to your baby.

I'm now diet and insulin controlled and the diabetes will go once baby is born. At the 32 week scan, stomach was much more in proportion, since managing the diabetes.

So maybe this could be your situation, although I didn't think it usually happened that early, thought it was much later. But might be worth checking with your MW...

Thanks Dawn. I'm actually not too worried about the huge tummy as my DS also had a vast tummy. In fact it was so big at a scan at 36 weeks the computer could not deal with the figures and the sonographer had to work out the measurements by hand. Because I'd been taking part in a research study, I'd had the full glucose tolerance test at 28 weeks and that showed that I did not have diabetes. I had just grown a big fat porky boy. I'm pretty sure that my babies big tummy now is probably just the same thing, but I will definitely get this checked out with MW, just in case.

The hospital seemed more concerned about the small head and also the discrepancy between the small head and big tummy.

Oh dear - well, think yourself lucky on the GD side - not pleasant that I haven't been able to have chocolate, biscuits or cakes since 28 weeks.

Hope everything is Ok though and that someone else pops on who can tell you more!!
