Kirsty, sorry I just noticed this thread. How are you going?? I totally sympathise with you

I suffered from gall stones when I was pg with Nicholas, I had one really bad attack late in pregnancy, but didn't know it was b/c of gall stones, then suffered from them again a few weeks after his birth.

I then suffered from them again when I was pg with ~Matthew~ and as you may/may not know, I ended up having to have my gall bladder taken out while I was pg with him, as it became severly inflamed.

As for preventing them, as the other girls have suggested low fat foods are the best and try and avoid all saturated fat all together.
