Yes, you can regain weight after any kind of liposuction. You have a set number of fat cells as an adult and liposuction simply removes a certain number of them. The ones removed are permanently gone. The remaining fat cells can grow bigger though if you gain weight. The good news is that there are fewer fat cells remaining in the area of the body that was treated and the “weight” tends to distribute itself more evenly in harmony with your new body contour. All in all, liposuction is not the answer to weight control, rather it is a surgical method of contouring the body. It is always best to be at a stable and realistic weight when you undergo this procedure.
