Most of the causes of thigh fat are too much fat. There are two ways to remove thigh fat: first, massage, you can jog for 5- 10 minutes, don't exercise too hard, you can sweat slightly. Then you can massage the thigh with a hot towel along the longitudinal axis of the thigh for about 5 minutes to promote blood circulation of the thigh and accelerate the catabolism of fat. Second, if the conservative treatment effect is not very good, liposuction can be used. Liposuction is to insert a metal tube into the fat layer and connect a negative pressure suction device behind the tube. The fat in the thigh can be sucked out by negative pressure, up to 3000ml at a time. It is best to wear a corset after liposuction, which is beneficial to the skin to cling to the fat layer and accelerate postoperative healing.
