Both of these procedures are done to bring the tummy back to its normal position. Liposuction is helpful when the skin of the tummy is tight and there is no sagging, otherwise Tummy Tuck is advised. The final advice is given after examination by the Plastic Surgeon.
In case of Tummy Tuck the redundant skin along with extra fat is removed and the abdominal muscles are tightened, it is usually required in females after multiple pregnancies but males may also need it.
Tummy Tuck not only results in amazingly nice contours but also greatly improves the mobility so that you can get back to routine activity of life.
