In general for tummy tuck, you want to have mainly loose skin, and not just loose skin along with fat. There's no standard magic number BMI, but most plastic surgeons would prefer if you're slightly overweight to thin to be the best candidate for tummy tuck. With a BMI of greater than 30, I'm afraid you should lose overall body weight before considering a tummy tuck. After getting clearance from your family doctor, please consider exercise with a personal trainer, coming up with a lifestyle change strategy that fits your needs, talking to a dietitian, and joining a support group. You will be better off losing the weight before having surgery. Best of luck to you!
All surgical procedures have risks. Many of those risks increase for patients who are extremely overweight. If you are able to lose more weight, you would become a better candidate for the procedure. You have the power to decrease your risk through diligent diet and exercise now. You will also have a better looking result if you are at a lower weight when you do your tummy tuck.
