Sometimes it becomes difficult to eliminate the excess fat accumulated on the abdomen, thighs and other areas of the body through exercise and diet. In such cases people turn to liposuction for achieving the aesthetically pleasing body. Liposuction removes excess and stubborn fat from the body using suction by small, thin, blunt cannula that are inserted through small cuts in the skin. Then fat is sucked out through these tubes from the specific targeted fat deposits. Liposuction has become safer, easier and less painful with improved technique.
Some of the newer techniques include: 1. Tumescent liposuction in which local anesthesia is given to numb the area of the body where the tube will be inserted. Anesthetic solution containing lidocaine and epinephrine is injected into the fatty tissue in a large amount following the traditional liposuction.
2. The technique that uses ultrasound to liquefy the fat which makes it easier to remove fat particularly from the neck, upper abdomen, sides and back. This is called ultrasound –assisted liposuction.
3. In laser assisted liposuction, low energy waves are used to liquefy the fat, which is removed through small tubes or cannula.
Liposuction is generally done as an outpatient procedure and does not require an overnight stay at the hospital unless large volume of fat is being removed. The treated area of the body is firmly wrapped to help reducing the swelling, bruising and pain; special fitted garment may also be used depending on the treated part of the body after surgery. There can be lot of bruising and swelling at least for 10 days for which patient may have to wear the compression garment for two three weeks. Doctor may advise some medicines and antibiotics as fluids may drain from the incision sites for several days. Most people can get back to their normal routine within few weeks after recovering from the treatment depending upon the treated area.
