Liposuction is a surgical procedure that involves injecting a fat dissolving chemical into an area of excess fat accumulation (eg. in buttocks, abdomen, thigh), then sucking out the partly dissolved fat through a 1 cm. diameter steel tube that is inserted through a cut in the skin.
The procedure is performed under general anaesthetic, and significant bruising is the main complication. It is usually performed for cosmetic reasons on those who are significantly overweight.
