Liposuction is a very common procedure for fat removal. The passage of time and the effects of gravity, coupled with weight fluctuations and pregnancy, take their toll on the body. The abdomen often becomes slack, the chin and neck can lose their definition, the arms become droopy and lumpy, and the buttocks and thighs may become saggy. Even with exercise and a healthy diet, some fat resists attack. Unsightly bulges and poorly fitting clothing can become frustrating.
