A: That is a tricky question. Men who have gained then lost abdominal (potbelly) weight or women who have been pregnant may require an abdominoplasty or "tummy tuck" to tighten the stretched-out abdominal muscles. Young women and men (usually under 30 years of age) may benefit from just abdominal liposuction to reduce girth. The skin of younger patients tends to contract well after liposuction.
