Do I need a cardiologist clearance for a mommy makeover? (BA, full tummy tuck with MR)

Thanks for your inquiry, really it is up to your team of doctors to decide.  Well managed thyroid disease does not mandate an obligatory visit with a cardiologist.

Your surgeon will be the one to advise if you need clearance from a cardiologist as well as your endocrinologist.  As your palpitations are related to your endocrine issues it is likely that will be the only clearance necessary as long as your palpitations are under good control.
