Liposuction is a type of cosmetic surgery that removes fat from the human body in an attempt to change its shape.
Areas operated on can include the abdomen, thighs, buttocks, and backs of the arms. The procedure may be performed under general, regional, or local anesthesia. It then involves using a cannulae and negative pressure to suck out fat. People operated on should generally have a normal weight and good skin elasticity. Thin tubes called cannulas are inserted into the body, dislodging fat cells and suctioning them out. Lipo can be performed on various body parts, including the abdomen and waist, hips and thighs, and cheeks, chin, and neck. It’s important to note that liposuction is intended to improve body contour and not to significantly reduce weight, cellulite, or sagging skin.
The best candidates for liposuction are men and women who are close to their ideal weight, but still have unwanted bulges of fat. Although liposuction can improve body contour at any weight, those with a BMI over 30 are typically not good candidates for the treatment.
How Does Liposuction Work?
Almost all liposuction procedures use what’s called a tumescent technique to minimize bruising and blood loss. First, a diluted fluid of local anesthetic and epinephrine (capillary constrictor) is injected into the fat being treated. Thin metallic tubes called cannulas are then inserted into the body through tiny incisions in the skin. Using the cannula, the surgeon makes controlled motions to dislodge the fat, which is suctioned out with a surgical vacuum or syringe.
Small areas of liposuction are often done using local anesthesia, with or without oral sedation. Larger areas are typically performed under IV sedation or general anesthesia. The procedure rarely requires an overnight stay at a hospital, unless a large amount of fat is being removed. Liposuction is often combined with other procedures, like a tummy tuck.The fat that’s removed can be purified and transferred to the buttocks, face, or other areas to restore volume loss or create a desired body shape.
