A tummy tuck is the best choice for patients who have loss of skin elasticity with an overhanging skin fold. This is often associated with underlying abdominal muscle weakness, also known as rectus diastasis, which is commonly seen after childbirth or weight fluctuations.    Liposuction is an effective technique to target stubborn pockets of fat that remain despite diet and exercise efforts. Liposuction by itself works best in patients that have good skin elasticity and no skin folds. Aside from the abdomen, patients commonly seek liposuction of the thighs, hips, buttocks, arms, neck or back.    In some cases, it may be appropriate to combine tummy tuck and liposuction in a procedure known as lipoabdominoplasty. This surgery allows for removal of stubborn fat pockets and excess skin and tightening of the muscles in a single procedure. Combining both techniques allows the surgeon maximal flexibility in contouring the abdomen and surrounding areas.
