I have syncope and anemia. What could be the effects on getting Rhinoplasty?

 First of all, it's important to get your anemia and syncope under control by her primary care physician before elective cosmetic surgery on the nose. Depending upon how severe the anemia is, the surgery should probably be held off until  your red blood cell count is normalized. Probably best to get a letter of clearance from  Your primary care physician before the rhinoplasty procedure

Before rhinoplasty, a thorough medical evaluation will ensure that the procedure can be performed safely. We like to ensure that our patients' health is at its best at the time of nasal cosmetic surgery

You need to be evaluated by your medical doctor to determine your reasons for being anemic and then treated appropriately before considering any surgery.
