Hi Patrick,
it has been known for doctors to deny ADR surgery to patients because they are overweight. Your BMI should generally be between 20 and 25 in an ideal world. If it's up to 30 then certainly you should be advising your surgeon as your outcome will be far from good. I've experienced this with patients on a number of occasions and although it's not life threatening, it makes the surgery difficult for the surgeon to do, and it makes the recovery extremely difficult for the patient because remember this is an anterior approach. There is a link here to check your BMI out

I don't know if you do it in kilos in the USA -- -- -- I just thought this might help
Best,

PS there have been exceptions to this rule with bodybuilders and people of unusual statures
