I am taking Effexor and Wellbutrin, am I in risk to undergo tummy tuck surgery?

Hello and thank you for your question.  As long as you are in good health otherwise and can obtain medical clearance from your primary physician, then a tummy tuck could be safely performed.  If you are an appropriate candidate, this can be done through a low and short
incision, all completely below the bikini line. 
The belly button can be designed to look natural and have no scars on
the exterior.   Your muscles can also be
plicated resulting in a flat abdomen. 
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.

All medications must be cleared by your surgeon's scheduling department at the time of scheduling. After discussing all the medications, instructions should be given at that point.  There are numerous drugs that need to be stopped prior to any procedures so as not to interfere with anesthesia or the healing process.
