Before liposuction, it is important to be prepared to maintain your results. While liposuction reduces the number of fat cells in an area, you can still lose and gain weight. We recommend that you be at or close to your ideal weight before having liposuction surgery. Afterward, it's best to remain within 5 – 10 pounds of your post-surgical weight. Getting pregnant after liposuction will also alter your results; however, another surgery like a mommy makeover may be performed to refresh your appearance.
