A tummy tuck (abdominoplasty) is a procedure that tightens the abdominal muscles and eliminates excess skin to create a smoother, flatter look. There are different types of tummy tucks. A full abdominoplasty must be differentiated from a mini-tummy tuck or liposuction of the belly. Patients seeking a tummy tuck usually have stable weights, but have excess skin that does not contract after liposuction. Sometimes, the muscles may be weak or spread apart from several pregnancies. Dieting and exercise have not been effective and the patient feels that surgical intervention is necessary to regain their youthful shape.
