well i am 170kg and having number 6 i guess lucky for me i acn have my baby at our local hospital but i must say i can only have him at the big one jhh and not at belmont like i wanted but they have told me this is because of the number of babies i have had ,i dont know what to say i have come across 1 very rude doctor whom i have laid a formal complaint against because while yes i am very over weight my pregnancy is very uncomplicated and so were all my others and yes i was very over weight for them as well,and i didn't like hearing this doctor say that i was the hugest thing he had ever seen,how whould i have felt if the hospital refused to treat me not real sure about that one but i would be looking into it see what there reasons are maybe if they cant cope with you if you needed a c/s but i was assesed for that as well and even though that is the last thing i want they have told me if they have to they can do a c/s but jhh is the major hospital up here so i guess that helps,i really think you need to talk to the hospital and find were they stand on this and take it from there were is the nearest large hospital to you.
best of luck try not to let them get you down us bigger mums are just as intitaled to good care and respect as everyone else.
