Hello and thank you for your question. The main benefit of a tummy tuck is in achieving a narrower waist and improved abdominal contour. The weight loss is minimal -- the amount of skin and fat removed is rarely more than a few pounds. However, from talking to many patients, the sight of a "new you" is quite a motivating force to go to the gym and continuing to improve your overall appearance and general fitness, which will help you lose weight subsequently. Also, when I perform an abdominoplasty, I tend to tighten the abdomen significantly which I have had patients say gives a sense of fullness and early satiety – this can help patients further lose weight. Be sure to seek a consultation with an aesthetic plastic surgeon who addresses all your concerns and discusses the surgery details including the risks and benefits of the procedure, recovery time, and post-operative course. When I perform an abdominoplasty, the necessary skin and fat is removed, the abdominal muscles are tightened, a small umbilical incision is made that is not externally visible, and a short, low waistline incision is designed to be easily hidden by your underwear or bikini. Please view plenty of before-and-after pictures in real women (and not just computer-generated images) who have a similar abdominal appearance to yours, and preferably at different time frames (3 weeks out, 3 months out, etc) to more accurately predict your own surgical outcome. And lastly, I think the most important component of the consultation is to establish a good connection with your plastic surgeon. If you don’t feel you have a good connection with your plastic surgeon after your consultation, he/she may not be the best surgeon for you. Good luck.
