You may still be a candidate for body contouring in the future, but I would not treat an active flank/lumbar hernia as a routine BBL case. A lumbar hernia means there is a weakness or defect in the abdominal wall, and liposuction around that area, surgical positioning, postoperative swelling, compression, and the physical strain of recovery can all create extra risk if it is not evaluated first. The first step should be confirmation of the diagnosis and size of the defect, usually with imaging such as a CT scan if your doctors feel it is needed. You should be evaluated by a general surgeon or hernia specialist before elective cosmetic surgery. They can tell you whether the hernia needs repair, whether mesh is needed, and how long you should wait after repair before considering liposuction or a BBL. In many cases, it is safer to repair the hernia first and allow full healing before elective fat transfer. Sometimes procedures can be coordinated, but that depends on the hernia, the repair plan, contamination risk, mesh placement, and the plastic surgeon's ability to safely perform liposuction without compromising the repair. I would avoid aggressive liposuction directly over or around an unrepaired hernia. For a BBL, the surgeon also needs to think about donor fat availability, safe fat injection technique, anesthesia risk, and your ability to recover while protecting the hernia or repair. My recommendation would be to get clearance from a hernia surgeon first, then consult with a board-certified plastic surgeon who can review the imaging and plan the safest sequence. If the hernia is symptomatic, enlarging, painful, or associated with nausea, vomiting, bowel symptoms, or skin changes, that should be addressed promptly rather than waiting for cosmetic surgery.
