Unfortunatley generally yes your options are more limited- alot of hospital have a cut off limit of weight (I *think* it based on BMI of 39 or above). In the hospital system you are generally counted as high risk, but it doesnt always mean you are limited for your actual birth choices. I was counted as high risk because of my weight for both my pregnancies, but I delievered both babies vaginally, DD was a bit intense because she was distressed and it was a get her out quick situation. But I gave birth to DS on all 4's on the bed with only 2 midwives in attendence, no drama no complications.

I guess the best thing to do is to know what you want, and not let yourself be bullied into having any medical intervention that is not absolutley neccesary
