A good body is what everyone wants to have. With the continuous development of liposuction technology in recent years, more and more people have realized their dreams, and through liposuction, they can easily achieve the purpose of body contouring with immediate effect. What are the risks associated with the changes it can bring to people? Liposuction is one of the plastic surgery body sculpting procedures, the principle is to use negative pressure attraction and (or) ultrasonic high-frequency electric field and other physical and chemical means, through a small skin incision (generally 0.5 ~ 1 cm) or puncture hole method to suck out the excess fat in a part of the body, in order to achieve the purpose of rapid local fat reduction and shaping. For those who want to lose weight through liposuction, we should first understand the cause of our obesity: when did it originate? What is the rate of weight gain? Are you suffering from any diseases that cause obesity? Are there any obese members in the family? Is there any family history? The best indication for liposuction is that the whole body is not too obese, only the local fat accumulation affects the beauty of the shape, the skin is elastic and not sagging, and for some morbid obesity: such as hormone caused obesity is not effective, should treat the original disease. And liposuction is not equal to weight loss, the main role of liposuction is to improve the shape of the body. If some people are not overweight, but the local fat accumulation affects the shape, they can choose to do liposuction surgery to shape, while weight loss is for overweight, the two are not equivalent. For liposuction surgery, the principle of “small amount and many times” should be followed. With fewer sites, there will be less trauma, faster recovery, less pain, and no need for general anesthesia. On the contrary, large area fat suction is very traumatic, painful, slow recovery, and requires general anesthesia, too much fat at one time, will cause a large loss of body fluids and electrolytes, or even chaos, other accidents may occur, complications, and greatly increased risk, so it should be stopped. The plastic surgeon and the plastic surgeon together to develop a detailed liposuction plan, to pay attention to the coordination of the shape, not how much you want to pump, where you want to pump, you need to choose a reasonable liposuction program according to their own situation. The common areas for liposuction are the abdomen waist, hips, thighs, upper arms, etc. Not all parts of the body can be liposuctioned. Some parts of the body cannot be liposuctioned, such as the front and outside of the calves and forearms. These parts of the body are mainly muscular and have little fat, so even if fat aspiration is done, the results will not be good. In addition, for the face and calves, because of the rich nerve distribution, aspiration must be performed with caution. Before the operation, besides general examination: such as blood routine, coagulation time, etc., pay attention to inform the doctor if there is hypertension, heart disease, bleeding disorders, drug allergy, etc. Female beneficiaries should avoid menstrual period, and if there is furunculosis, boils, eczema, etc. on the skin of liposuction area, they need to wait for healing before doing the operation. After liposuction, you should pay attention to a light diet and avoid spicy and stimulating food. In the first few days after surgery, there will be a lot of exudate, so pay attention to keep the dressing clean and dry and change it in time, and the skin may appear petechiae and seroma in the short term, which is caused by many small blood vessels being destroyed when sucking out. There will be swelling and soreness in the initial period after surgery, and the local skin may feel hard and numb, which is normal. You will need to wear a shapewear for 3 to 6 months after surgery. Will liposuction rebound after surgery? Generally speaking, after liposuction surgery, if you carry out perfect care and keep your shapewear habits for 3 to 6 months, you will not rebound. The number of fat cells in adults has been constant, people will be fat and thin because the cell volume increases and decreases, the usual non-surgical weight loss methods cannot reduce the number of fat cells, only liposuction can make the absolute reduction of the number of fat cells, after the number of fat cells is reduced, it is impossible to increase again, thus the effect after liposuction is permanent and will not rebound. Some people may feel slightly fatter after liposuction for a period of time than when they were first liposuctioned. This is actually not a rebound, but is often due to improper diet causing the remaining fat to become larger and fatter.
