Thank you for the question. These terms refer to surgical procedures that serve to improve the appearance of the abdominal wall, often performed for patients who have had pregnancies and/or weight gain and loss. Generally, the operations involve removal of excess skin/adipose tissue and usually plication (re approximation) of the abdominal wall muscles (that may have spread with pregnancies and/or weight gain/loss). Liposuction surgery is a tool often used for contouring purposes during these procedures.
Generally speaking, the “ideal” patient for tummy tuck surgery is one who has completed pregnancies, is psycho socially/emotionally/financially stable, has an excellent social support system surrounding him/her, is capable of arranging enough recovery time, does not smoke and who has reached a long-term stable weight.
I hope this, and the attached link, helps. Best wishes.
