What is liposuction?
Liposuction is a procedure that removes excess fat through a suctioning process. Although
it's not a substitute for weight loss, it can change the body's shape and contour.
Liposuction can be used to remove excess fat that doesn't respond to exercise and
dieting, including fat around the thighs, stomach, upper arms, buttocks, or the waistline.
What are some different liposuction techniques?
Some of the different liposuction techniques include the following:
Tumescent technique. The tumescent technique involves the injection of a large quantity of a medical solution
into a fatty area. The medical solution is a combination of medicines that numb the
area, as well as shrink the capillaries and prevent blood loss. Afterward, a tube
connected to a vacuum is inserted into the fat to be treated. The fat is then suctioned
Ultrasound-assisted lipoplasty. In the ultrasound-assisted lipoplasty, a special tube that produces ultrasound energy
is used. This ultrasound energy breaks down the walls of the fat cells turning them
to liquid. The fat is then suctioned out.
Laser-assisted lipoplasty. Lasers help with liposuction by heating fat to make removal more efficient. It causes less
bruising and faster healing.
Power-assisted liposuction. A tool on the end of the suction device helps to cut through the fat, making it easier
Possible complications linked to liposuction techniques
Possible complications of liposuction may include:
Injury to the skin or deeper tissues
Irregular skin surface. Changes in the skin surface can occur after liposuction, giving it an uneven or baggy
look. There can also be changes in the skin color; and areas that may become numb
or persistently painful.
Greater risks if large areas are treated. The risk for infection, the formation of blood clots or fat clots, excessive fluid
loss, and damage to the skin, nerves, or vital organs is greater when large areas
Lidocaine toxicity or fluid in the lungs. If the lidocaine content is too high, it may cause lidocaine toxicity. If too much
fluid is injected, it may cause fluid buildup in the lungs.
Who are candidates for liposuction?
Generally, people of normal weight who have localized areas of protruding fat achieve
the best results, however, people who are slightly overweight can also benefit from
liposuction. The best candidates for liposuction include the following:
Normal-weight (or slightly-overweight) people
People with firm, elastic skin
People who have pockets of excess fat in certain areas
Physically healthy and psychologically stable people
People with realistic expectations
Age is not a major factor, although older persons with diminished skin elasticity
may not have the same results as persons with tighter skin.
