Liposuction at the waist in a regular hospital will not rebound. The number of adult fat cells has always been the same, and people will get fat and thin because of the increase or decrease of cell volume. The usual non-surgical weight loss methods can't reduce the number of fat cells. Only liposuction at the waist can absolutely reduce the number of fat cells. After the number of fat cells decreases, it is impossible to increase it. Therefore, the effect of waist liposuction is permanent and will not rebound.
