Hello, I'm Dr. Zhao from New Life. After 18 years old, the number of human fat cells is in a constant state, and obesity mainly depends on the fullness of fat cells. It can also be said that under the same satiety, the more fat cells there are, the fatter the human body will be. Using surgery to lose weight-liposuction to lose weight, most fat cells are physically removed. Even if a few more fat cells are filled, the filling of two cells is always much thinner than that of 20 cells. Pathological obesity should be ruled out here. The so-called pathological obesity refers to the abnormal division of fat cells in patients, but this phenomenon is very rare. In short, liposuction is not easy to rebound.
