Usually the best candidates for tummy tucks are those people who have a large amount of loose skin or fat around the abdomen or stomach. In addition the best candidates are often in reasonably good shape and not very obese. Often these individuals have an area of fat or excess skin around the abdomen that refuses to disappear.
Some of the possible causes creating the best kind of candidates are as follows.
Weight Loss - People who have lost a lot of weight and have prevented the weight coming back. This could be for various reasons such as exercise habits, or a change in diet.
Skin Stretched During Pregnancy - A pregnancy where the woman has put on a lot of weight during gestation and consequently lost it rapidly after birth, can sometimes leave a lot of loose skin stretched around the stomach. Tummy tuck surgery can help these woman achieve a tighter stomach and waist.
