Thank you for the question and picture. Unfortunately, the photograph is somewhat dark making its evaluation somewhat difficult. Generally speaking, I think you are on the right track; best to achieve your long-term stable weight through diet and exercise prior to evaluating the appearance of your abdominal wall. Unfortunately, despite best efforts, the changes that occur after pregnancy may not be completely reversible through diet and exercise. Some women, despite best efforts with diet and exercise benefit from from tummy tuck surgery to re approximate the abdominal wall muscles and remove the “excess” skin/adipose tissue present along the lower abdominal wall. Although difficult to evaluate in your photo graph, if an umbilical hernia is present, it can be repaired at the same time. 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.
