When performed by a properly trained, board-certified plastic surgeon in an accredited facility with appropriate patient selection, abdominal liposuction is generally safe. However, it's still surgery, and the risk increases with larger volumes of fat, higher BMI, smoking, and certain medical conditions. As far as pain goes, you will be comfortably anesthetized during your procedure. Most patients describe feeling very sore, as if their muscles are bruised, rather than experiencing sharp pain. The first several days usually bring the most discomfort, which typically improves over 1 to 2 weeks; however, it may take several weeks for soreness and swelling to settle fully.
