Hello, Thank you for your questions regarding non-surgical alternatives to a tummy tuck for someone who is been 30 to 40 pounds overweight for 15 years. The best non-surgical alternative to a tummy tuck for somebody was been 40 pounds overweight is diet and exercise. I would suggest a high protein diet followed by calorie restriction. In addition, I would suggest aerobic and anaerobic exercise. Get a trainer if you must. Another alternative may be a medical weight loss program. There are a significant number of safe medications which can accelerate weight loss. Please seek a reputable medical doctor or registered dietitian, not an online store or the vitamin shop at the corner. If you still cannot lose the weight, unfortunately, there are no good non-surgical alternatives to a tummy tuck in your case. There are modalities like CoolSculpting, Thermage, and Radio Frequency Therapy. However, you will get very limited results and I do not think if you are 40 pounds overweight, they would be worth your time and money. Instead, I would explore why you are reluctant undergo surgery. Surgery will achieve the best results. If you are relatively healthy, and your medical labs, EKG, and chest x-ray are within normal limits, a tummy tuck or abdominoplasty maybe a low-risk procedure for you. The results after a tummy tuck can be life-changing. When considering a tummy tuck, please seek an expert, board-certified plastic surgeon in your neighborhood who has performed hundreds of abdominoplasties. If you have any more questions regarding the non-surgical treatment of the abdomen or any plastic surgery procedure in general, please contact my office. Sincerely, Dr. Katzen.
