Do I have to remove my mirena IUD for lipo and BA?

No you don't have to remove you IUD. A couple of times a year patient come in for surgery and the pre-op pregnancy test gives us a really big surprise. So in some ways you could say that that IUD will guarantee that no surprise happen at the time of surgery. Good luck.

Personally I would not recommend removing the mirena IUD unless there was some underlying reason to do so. Your PS is best to advise. 

Dear Neka,    As long as you do not have any side effects from your IUD like bleeding, PID, breasts tenderness etc., you can keep it on place. The more important issue for you should be selecting the right plastic surgeon. Always, consult with experienced board certified plastic surgeon who operate in accredited surgery center. Check the before and after pictures in the photo gallery to make sure that they are numerous, consistent and attractive.              Best of luck,                                   Dr Widder
