Generally in women, as well as in men, the abdominal skin and muscles sag and get loose due to deformation resulting from excess weight gain. The most important factor in women is pregnancy. With the rupture of the tissues between the muscles forming the anterior abdominal wall and keeping the internal organs inside to make the muscles appear flat, the muscles are separated from each other and the abdomen appears protruding and saggy due to internal pressure of the organs. If not only your abdomen is fatty, but also the muscles are separated and sagged, it is possible that you can get a whole new look with "abdominoplasty" surgery.
