Thank you for your question regarding what to do with excess skin of your lower abdomen. You mentioned that you were overweight and you have had children. Unfortunately, this is an extremely common scenario. Unfortunately no matter how hard you work out your skin will not recoil. This is due to your genetics, weight loss, and history of pregnancy. Therefore you need a tummy tuck. In my opinion, no amount of working out will help the skin to contract. Also, isolated liposuction to the lower abdomen will only remove fat and probably make your excess skin worse not better. Therefore in my opinion without a physical examination or better pictures, you need a tummy sucker of Domino plasty. The procedure takes approximately 3 to 4 hours to complete. The procedure should be done under general anesthesia. Plan on a 2 to 3-week recovery. Thank you for your question regarding what kind of surgery you need after weight loss and children despite you’re working out all the time. If you have any more questions regarding a tummy tuck, lower body lift, 360 circumferential lower body lift, belt lipectomy, belt abdominoplasty, or belt dermolipectomy please contact my office. Since the body lift is a big procedure, please seek an experienced, board-certified plastic surgeon with significant experience performing the lower body lift. Do your research. Make sure they have performed at least 100 tummy tuck or circumferential lower body lift surgeries and have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. If you cannot find an experienced, tummy tuck or lower body lift surgeon in your neighborhood, consider traveling out of state if you must. Sincerely, Dr. Katzen.
