People often ask questions about weight loss in their daily work, and they are influenced by all kinds of liposuction advertisements in the society, thinking that they can achieve the purpose of weight loss by taking out the fat from the body as they like through a simple small surgery, which is a serious misunderstanding of liposuction. As we all know, obesity is divided into two kinds: local obesity and whole-body obesity. Whole-body obesity can only be treated by controlling diet (no matter what method is adopted), strengthening exercise, or with drugs or and treatment of primary diseases or auxiliary liposuction and weight loss surgery, which requires a comprehensive and systematic treatment program to achieve long-lasting and stable results. For most patients with total body obesity, it is unlikely or very limited to achieve the goal of reducing weight, lowering blood lipids and blood sugar, and thus making the body healthy and beautiful through liposuction, which can reduce your subcutaneous fat and improve your appearance to a certain extent through local weight loss, but the fat around the internal organs cannot be suctioned! The fat around the viscera that really affects your health cannot or will not be significantly reduced by liposuction! However, it is not the same for locally obese patients. She or he is not fat or slim, but a certain part such as the abdomen, jaw, waist, etc. is locally bulging and affects the beauty, and these parts are impossible to lose through exercise, or due to a certain part of obesity affects life or walking, etc. It can be done through liposuction, which is simple, effective and immediate, and cannot be replaced by other methods. The procedure is simple, effective and immediate, and cannot be replaced by other methods. In other words, liposuction and weight loss are not exactly the same two concepts. Liposuction, or liposuction for short, emerged in the 1970s, became popular in the United States in the 1980s, and was introduced to China in the late 1980s. It has now become one of the most performed cosmetic surgery procedures in the world and in China. Liposuction or liposuction is a surgical method performed by a professional plastic surgeon to remove fatty tissue from a specific part of the body through a tiny incision, thereby reducing the number and volume of fat cells in a definite and reliable way to shape the beauty of the human body, which is non-rebounding (unless weight gain). For this reason, liposuction is also known as a body sculpting technique. From this we can also see that this procedure is more focused on the improvement of the human body shape fetish. With this procedure, fat can be suctioned from almost any obese part of the body – shape-sculpting – in order to improve the shape. Fat aspiration can be divided into several types of liposuction such as swelling liposuction, electronic liposuction, ultrasonic liposuction and syringe liposuction according to the different ways of aspiration. In addition, there are also resonance liposuction, poly-liposuction, laser lipolysis, drug lipolysis and so on in the advertisements, and the names are dazzling. However, no matter what they are called, ultimately the excess fat under the skin is sucked out of the body through negative pressure. The method used varies depending on the area to be liposuctioned. A double chin or slightly obese cheeks can be treated with just the syringe method, which is a less invasive procedure with good results and no visible scars. If you only need to improve the appearance of a certain part, such as the lower abdomen, it can be performed under local anesthesia in an outpatient clinic, and most of you can go to work after 3 days of rest, which has less impact on work and study; however, if you need to improve the appearance of multiple parts or lower limbs at one time, you need to be hospitalized to perform the surgery, which takes about 7 days. Fat aspiration is suitable for those who have too much local fat, good skin elasticity and no obvious sagging of the skin in the corresponding area. For those with severe skin sagging, fat aspiration should be performed along with partial skin excision at the sagging area. Liposuction is a surgical method to remove localized fat accumulation that cannot be achieved by other weight loss methods (such as diet, exercise, and weight loss drugs). It is mainly for healthy people with relatively normal weight localized fat accumulation (e.g. abdomen, chin, thighs, upper arms, upper breasts, cheeks, chin, etc.). In other words liposuction is a localized weight loss procedure. Liposuction cannot reach the point where there is no fat left at all, i.e. it is not possible to reach the point where the subcutaneous is muscle. The reason is that there are many large blood vessels and nerves in the subcutaneous fat, and if these are damaged, the skin will become necrotic and the consequences will be unthinkable. Therefore, it is important to leave 1-2 cm of fat under the skin. Although the incision is very small and safe, the invisible trauma under the skin is not small, just like other surgeries, there is a recovery period, and some “normal adverse manifestations” may occur for a while after the surgery, such as: skin bruising, mild numbness, local hard knots, local tissue edema and other surgical reactions; in addition, there may be In addition, there may be bleeding, hematoma, seroma, infection, local sensory loss, unevenness of the liposuction site and other adverse reactions; if there is too much liposuction at one time, the operation is too rough or the physical condition is poor, electrolyte disorders, fat embolism and other life-threatening complications may occur. Although these complications are very rare, they can have serious consequences, so the surgery should not be taken lightly. Of course, most of these complications are recoverable, and there is usually a recovery process of about 3 to 6 months, depending on the part of the body being liposuctioned. What should I pay attention to before and after liposuction? (1) A thorough pre-operative examination is a prerequisite for safe surgery and should never be simplified. (2) Discuss with your physician about the areas to be liposuctioned. If there are many areas to be suctioned, a comprehensive and reasonable surgery plan should be made, remembering that the desire for speed is not enough. (3) The surgery should avoid menstruation period ⑷ Due to the large amount of local expansion fluid injected during the surgery, the external dressing may be penetrated on the day after the surgery, and in case of lower abdominal liposuction, there will be edema in the perineum, which are normal phenomena. Appropriate activities can be done after the operation, strenuous exercise or long term bed rest is not advocated. After the liposuction area is bandaged with pressure for 5 to 7 days, the elastic tights are replaced for 3 to 6 months. (5) The “normal poor performance” of the liposuction site in the short term after surgery is usually recovered in about 3 to 6 months. (6) Always follow medical advice. Don’t be fooled by the dazzling terminology if you perform liposuction surgery! Remember: safety is more important than beauty.
