How safe is it to have a tummy tuck and BBL being Hep B positive? What risks should I consider?

The best place to begin is a visit to your primary care doctor, or specialist who treats your Hep B.  Discuss your desire for a tummy tuck and BBL.  If given clearance you should be fine to proceed in scheduling a consultation with a board certified plastic surgeon.  

Dear Thinking20,
you will need to get a clearance prior to surgery. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Transmission of the hepatitis B virus can happen if you come into contact with an infected person’s bodily fluids or blood so you will need clearance from the medical specialist who is treating your Hep B. You will also need to tell the board certified PS during your consultation so that he/she can take precaution to decrease the risk of intraoperative transmission: use of double latex gloves, changed hourly, enclosed hood and face-masks,  knee-length impermeable gowns, a combination of shoe-covers with coverage to the knee and disposable drapes. Inadvertent pricks or cuts should be bled and washed immediately with iodine, soap and water.  Would recommend that you have the lipo and BBL first; six months of so later, have the TT.
