Roughly, from outside to inside, the abdominal area consists of the skin, subcutaneous fat tissue, and the abdominal wall muscles. The outermost tissue of these layers is the skin and has the potential to tighten-loosen at a certain rate. Especially as a result of excessive weight gain and weight loss, each time, our skin widens and narrows again, and a little more loss occurs each time.
After a while, no matter how much weight is lost, the skin cannot adapt to the underlying muscle tissue and tighten, and therefore sags. When sagging occurs, there is no return; and the intensity of sagging increases with the negative effect of the gravitational pull. On the other hand, pregnancies lead to the expansion of the muscles in the anterior abdominal wall, loosening in their connection with each other, and angles occur to the edges. As a result of this, the abdominal organs push the protective muscle and membrane layers before them more easily; and especially after eating, there is an abdominal image that shows significant swelling.
