The main purpose of liposuction is to reshape one or more areas of your body, not to reduce body weight.
Liposuction is usually done as an outpatient procedure in a properly equipped doctor‘s office, ambulatory surgery center, or hospital. In general, it does not require an overnight hospital stay unless a large volume of fat is being removed. If a large area or volume of fat is being treated, general anesthesia or deep sedation with a local anesthetic may be used.
During liposuction, small, thin, blunt-tipped tubes (cannula) are inserted through tiny cuts in the skin. Fat is suctioned out through these tubes as the doctor moves the tubes around under the skin to target specific fat deposits.
In recent years, improved techniques have made liposuction safer, easier, and less painful. These newer techniques include:
Tumescent liposuction. A local anesthetic is used to numb the area of your body where the tube will be inserted. Next, a large amount of an anesthetic solution is injected into the fatty tissue before traditional liposuction is done.
Ultrasound-assisted liposuction. This technique uses ultrasound to liquefy the fat, which makes it easier to remove. This technique may be particularly helpful in removing fat from the upper abdomen, sides, and back.
Laser-assisted liposuction. This technique uses low-energy waves to liquefy the fat, which is removed through a small canula.
