Liposuction is not considered a weight loss surgery, as it is primarily a cosmetic procedure. Liposuction is a surgical procedure that removes localized pockets of fat from specific areas of the body, such as the abdomen, thighs, hips, arms, and back. The procedure involves making small incisions in the skin and inserting a cannula, a thin tube-like instrument, into the fat layer beneath the skin. The cannula is then used to suction out the fat cells, which are permanently removed from the body.
