This is major surgery, not a large cosmetic procedure: what that actually means
A lower body lift has among the highest complication rates of any operation in plastic surgery, and patients deserve that stated plainly rather than buried in a longer list of smaller risks. A circumferential wound in a post-weight-loss patient is long, under tension along its entire length, and passes through skin whose quality has been genuinely damaged by being stretched and then deflated. Wound separation somewhere along it is the rule rather than the exception, particularly at the back where sitting loads the closure directly.
The second point is equally important: this is major surgery with a genuine physiological load, not simply a large cosmetic procedure. Four to six hours of anaesthesia, extensive dissection, meaningful blood loss and a very large raw surface put it in a different category from abdominoplasty. It belongs in a hospital with proper monitoring and the ability to transfuse if needed, and the pre-operative work matters as much as the operation: stable weight for 6 to 12 months, corrected anaemia and protein deficiency, and no smoking. Surgeons who refuse to operate on smokers, or who insist on blood tests first, are protecting you from the complications this specific operation is genuinely capable of producing.
