I would like to have a TT, lipo, BBL ,BA and BL I was wondering if it is dangerous to do everything at the same time?

The number one issue for any surgery is safety.  Cosmetic plastic surgery is usually done as an outpatient to keep cost low. In order to do that safely we need to restrict the amount of time under anesthesia. You should consider doing your surgeries in two or three stages.  One option would be to do the liposuction and BBL during one procedure then to come back 3 months later after inflammation has settled down and do the tummy tuck with or without breast surgery.

Every surgeon has their preference over how many areas to treat in one surgery. I would recommend the lipo/BBL first followed by the breast and tummy tuck in a delayed fashion. I would see a board certified plastic surgeon to discuss your desires and how they would approach your procedures.
