Liposuction removes fat from your body using suction. 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.
Liposuction is usually done as a day-case procedure. In general, it does not require an overnight hospital stay unless a large volume of fat is being removed. Local anaesthesia is used in some cases. And you may or may not be given a sedative to help you relax. If a large area or volume of fat is being treated, general anaesthesia or deep sedation with a local anaesthetic may be used.
