Hi Kensi,
Yes, large weight changes can affect your surgery, but your surgeon will be the one to tell you what will be required. I don't know of any plastic surgeons that specialize in FFS in Virginia. The nearest FFS surgeons that I can think of are in Florida (Mardirossian), North Carolina (MacPhee) Pennsylvania (Rumer, McGinn, Leis) , New York (Bluebond-Langner, Lee), and Massachusetts (Spiegel). There are many, many others across the US. I live in Alexandria, VA and ended up going to Dr. Zukowski in Chicago.
I have to say, though, travel should be the least of your concerns for FFS. I don't know what course of treatment you are considering, but I had extensive FFS, everything from my scalp to my trachea, and recovery was hell. FFS is major surgery, and you will be essentially non-functional for a couple of weeks, and certainly in no position to take care of anyone 24/7, not even yourself. You should pick the best surgeon you can afford, have confidence in their approach, and be in agreement on what they propose to do.
With kindness,
Terri
