Can a Tummy Tuck be performed on an HIV person?

HIV by itself is not a contraindication to the surgery. 
Find a board certified plastic surgeon who performs hundreds of TTs each year. Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results. Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Yes, a tummy tuck or any other cosmetic procedure is safe to do in a patient who is HIV positive as long as they are in good health with no viral load detectable and normal CD 4 counts. Most surgeons will request medical clearance from your primary care physician. Please be upfront and advise your surgeon of your HIV status. Despite the low risk of transmission, additional precautionary steps can be taken in the operating room to lessen the risk of potential exposure to the surgical team. For instance, I minimize the number of surgical assistants who can potentially come in contact with sharp instruments and use special blunt tip needles to lessen the chance of accidental needle stick injuries in surgery.

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  If your HIV counts are stable and you can obtain medical clearance from your primary physician, then you can safely undergo a tummy tuck.   Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most
important aspect is to find a surgeon you are comfortable with. I recommend
that you seek consultation with a qualified board-certified plastic surgeon who
can evaluate you in person.
Best wishes and good luck.
