Hello and thank you for your question. I appreciate the importance of the question you are asking. With my own patients, we perform a thorough history and physical examination and go over the client's goals, budget, and expectations. Many people would prefer to get it all done at once as a) it saves time off from work/responsibilities, b) allows for one recovery, and c) is more cost effective. For safety reasons, I try to limit my surgeries to less than 6 hours at a time, and in most cases, for simple breast augmentation, liposuction of the abdomen/flanks/lower back and fat transfer to the buttocks/hips, we are able to achieve that in one surgery. In cases where there is more liposuction or work to be performed, we can do one surgery and then the other around 4 weeks later. I hope this helps answer your question. Please make sure to visit a board certified plastic surgeon who specializes in advanced breast and body techniques. Sincerely,Dr. Sean Kelishadi
