A tummy tuck surgery or abdominoplasty surgery is a complicated process though explaining what it is might be too simple. In the strictest terms, it is cutting off the excess skin and suturing up, so that there is a new tight skin in the place where it used to be big.
Normally, patients who have excess skin in the abdomen are those who seek and aim to have this type of surgery done to them. Nonetheless, it is important to keep in mind that when a person is overweighed and looses the excess weight there will be excess skin all over his or her body, in any physical part that was wide and big, mainly stomach, hips, arms, neck and thighs. Loosing the excess weight by any mean that is quick such as a gastric bypass and the like will cause the skin to stay sagging because it has lost elasticity and has not had the time to deal with the new situation of weight and body mass.
Of course patients that have such problems and that subject themselves to a tummy tuck will have a new flattened stomach, and they will feel better about themselves and about the image that they project to the world. However, a person that was once overweight will have the same problem despite the tummy tuck, there will always be things that he or she will not like about his or her new body such as the sagging skin in the rest of the body.
