When you gain weight, fat cells increase in size and volume. In turn, liposuction reduces the number of cells in a specific area. The amount of fat removed depends on the appearance of the area and the volume of fat. The resulting contour changes are generally permanent - as long as your weight remains stable.
After liposuction, the skin molds itself to the new contours of the treated areas. If you have good skin tone and elasticity, the skin is likely to appear smooth. If your skin is thin with poor elasticity, however, the skin in the treated areas may appear loose.
Liposuction doesn't improve cellulite dimpling or other skin surface irregularities.
Likewise, liposuction doesn't remove stretch marks.
To be a candidate for liposuction, you must be in good health without conditions that could complicate surgery - such as restricted blood flow, coronary artery disease, diabetes or a weak immune system.
