I had to have one with my first (even though I planned to have a natural birth) and the Dr was confused as to why I was there as although I was overweight/obese, I look smaller than I weigh. The numbers on the scale meant I had to have the appointment to see that they could get an epidural in ok. It was all fine and I didn't end up having an epidural for the first or two subsequent births. Interestingly I was much heavier for my 3rd, and I didn't have to have an appointment for her...

I agree it must just be a hospital policy. Just try to brush it off, go along, get seen and try to put it out of your mind.

The Dr told me you had to be massively obese for it to be a problem.
