Tummy Tuck San Antonio: We get many calls in our San Antonio office from women who are confused about the difference between abdominal liposuction and a "tummy tuck", or abdominoplasty, as the procedure is called. Liposuction is the procedure of choice if there is subcutaneous fat present. A tummy tuck is only indicated if there is excessively loose skin, or if the abdominal muscle has been damaged with pregnancy or surgery and is no longer responsive to toning with exercise.
