Is it possible for someone with an autoimmune disease (Lupus) to get Smart Lipo and a Brazilian butt lift?

I'm interested in body contour but have a history or various conditions steaming from an SLE lupus condition. I have been doing very well for the past year, as close to remission that I've ever been in (10 years). When dealing with a person with lengthy but past previous health concerns, what is the major determining factor in exceptence, or rejecting a patient? Also, is there a specific medication type that the patient isn't allowed to be on when attempting a cosmetic surgery?
