Tian Fei expert: There are two reasons why you won't get fat after liposuction. First, in medicine, the number of fat cells will increase until childhood, and then the number of fat cells will remain at a fixed level. Obesity is caused by the enlargement of fat cells themselves. Therefore, after the operation to reduce fat cells, even if the fat cells are doubled, the obesity in the liposuction area will not be obvious. Second, in the process of liposuction, the liposuction tube passes through the adipose cell layer many times. The site where the liposuction tube passes is scarred after operation, forming a solid omentum between fat cells. Even if you are obese, the size of fat cells is limited.
