Can people who have autoimmune rheumatological complications undergo plastic surgery?

depending on your particular situation you may well be able to have plastic surgery.  You probably wouldn’t want breast implants because of the possible link between implants and autoimmune disease which is still uncertain.  But other procedures should be no problem.

Thank you for the question.
 Plastic surgical procedures can be done safely for patients with a variety of different “medical conditions”. Careful evaluation and treatment of the medical condition is necessary prior to determining the appropriate candidates for the tummy tuck procedure.  In your case this would be best done by your rheumatologist.  The physicians who know your situation best would be best suited  to discuss your suitability for the procedure and the potentially increased risks/ complications that you should consider.
 
If/when the time is right, please make sure you are seeking consultation with  well experienced board-certified  plastic surgeons who preferably work with board-certified anesthesiologists.

I hope this helps.  Best wishes.
