I am technically obese. My ob has discussed my weight only so far as to calm my worries about something I read in the media that was negative (and scary) about obese women giving birth. She has asked me my weight a couple of times in my visits, but never made a big deal out of it. I've gained around 10 kg so far in my pregnancy (33 weeks).

I had my glucose tolerance test a little early, just in case (I also have borderline PCOS, so I was considered at a higher risk for GD), and my results were perfectly normal.

My blood pressure has been absolutely fine so far throughout my pregnancy. No sign of pre-eclampsia either, or any other problem at all.

I am quite physically active (decreasing now, admittedly), am still riding my bicycle around locally (I stopped riding it to work at about 24 weeks). I am walking lots and keep busy through the day. I eat well and am careful about my health in general. I haven't bothered with a low-GI diet, but generally eat sensibly.

I am sure that I have as good a chance as any other healthy woman of having a perfectly normal pregnancy and birth.

I think you should absolutely complain to the hospital about that doctor and request to never see him again and to not have him attend your birth. I am sure there is space in the system for this. Hospital systems are large and daunting, and like other large, daunting systems I think they are probably a lot more flexible than they look - it's a question of keeping on asking firmly until they give you what you want. I think that his attitude actually puts you and your baby at more risk and that this is worth getting "up in arms about".
