Sometimes simply dieting and exercising are not enough to take care of waistline problems. In such cases, a patient may wish to consider a tummy tuck (or abdominoplasty). A tummy tuck is the surgical removal of excess skin or fatty deposits from the abdomen, along with the repositioning of abdomen muscles into a tighter formation. This bodily enhancement procedure is designed for those who wish to have a flatter and tighter stomach. It is also helpful in remedying the vertical separation of abdomen muscles known as diastasis, which can occur following pregnancy.
