Hi Ahmedbenhamidaa, The 360 circumferential lower body lift removes skin and fat from the abdomen, pubic region, hips, and buttocks. Typically, the 360 lower body lift can take 5 to 8 hours to complete. This procedure is performed under general anesthesia. The recovery period is different for every patient, but is usually 3 to 4 weeks.The upper body lift removes excess skin and fat from the chest, lateral breast, and back. Typically, this procedure can take 3 to 4 hours under general anesthesia. I would suggest staging the 360 lower body lift and the upper body lift for several reasons. First of all, I think the anesthesia is a little too long. To reduce the anesthesia and surgical time, I would suggest staging the procedures. Secondly, during the 360 lower body lift, the buttock is pulled up and relies on the blood supply of the lower back. During the upper body lift, the back is pulled up and relies on the upper back for its blood supply. Due to pull of different vectors and the added risk of blood supply, I do not think it is a good idea to combine the upper and lower body lift.I would wait 4 to 6 weeks between procedures. Please be sure you a board certified plastic surgeon with significant experience in lower and upper body lifts as well as with weight loss patients.Good luck. Sincerely, Dr. Katzen
