Can I get a second tummy tuck after gaining 20 pounds?

I think you should lose the weight and then re-evaluate your skin excess. Most likely, you won't need anything, but certainly getting another tummy tuck is possible.Best wishes, Dr. ALDO :)

In your situation, it is often best to proceed with liposuction and then excision of any loose skin at the old scar. An examination by a board-certified plastic surgeon would be able to better evaluate the situation and review your options. It is unlikely you would require a full second tummy tuck.

Yes, you can certainly undergo further body contouring surgery once you have achieved your long-term stable weight.  Exactly what operation you will benefit from will depend on your physical examination, at that time. For example, some patients in your situation may benefit from further liposuction surgery. Some patients also benefit from skin excision and/or further abdominal wall muscle tightening.  Best wishes as you work toward your goals and for an outcome that you will be very pleased with.
