I didn't have any problems from my weight during my pregnancy other than the attitude I got from my OB.
I had a high risk pregnancy due to factors other than the weight, and the only reason I stuck it out with him was that he was the only high risk specialist in my area, and he was very good with taking care of high risk pregnancies.
But the whole time, he had this attitude about the weight, where he wanted to keep my weight gain down to 15 pounds during the course of the pregnancy, and my 20 pound gain was like a crime.
When I passed the glucose test, he almost seemed incredulous, as if being overweight was a guarantee of gestational diabetes. And even after the test came out ok, each pound I gained he kept making comments about the baby gaining too much weight and the baby being too large.
Well, it turned out that my predicted humongous baby only weighed 7 pounds at birth. He was a good doctor in many other ways, but I was just so worried during the course of my pregnancy about food, that I couldn't possibly ever go to him again.
Some people think that when you are overweight, it's because you don't worry about food, but it's true that more often people who are overweight worry about food ALL THE TIME.
Finding that sort of ignorance in a doctor disturbed me. It's not that you have to be a super genius to be a doctor, but I'd much prefer someone who is less influenced by personal assumptions.
