Liposuction is basically a tube with a patient on one end and a source of suction on the other.
The most important thing to know about liposuction is that it is for people (of either sex) who are at or near their ideal body weight with good skin tone, who have localized fat deposits resistant to dieting. It is never a substitute for weight loss.
Liposuction is more suitable for certain areas of the body than for others. The lower abdomen, flanks, outer thighs and knees do well. The upper abdomen, where the fat is more fibrous, less well. The inner thighs, while frequently requested, are rarely treated because the skin is thin and tends to ripple. The cannulas or suction tubes used today are smaller than those used in the past, which permits greater control and allows the procedure to frequently be done in the office under local anesthesia. Unfortunately, liposuction cannot treat cellulite.
