1. What is liposuction to lose weight?
Secret 1: Inject swelling liquid under anesthesia before liposuction.
According to experts, liposuction is to cut a small hole in the surgical site, extend the liposuction tube into the fat layer, and then suck out the fat. There are many methods of liposuction, such as negative pressure, vibration, ultrasound and so on. General or local anesthesia was performed before liposuction, and the same amount of swelling liquid was injected. Director Zhang said that the swelling fluid is mainly composed of sodium bicarbonate, normal saline and anesthetic, which can reduce the amount of bleeding during operation and separate subcutaneous fat from some tissues for liposuction.
Secret 2: liposuction is not to lose weight, and the weight will not drop sharply.
"Liposuction is not suitable for obese people, it is used to improve the body curve." Experts say that if you take a balanced diet and proper exercise, there is still a part that cannot be eliminated, and you can shape it by liposuction. After liposuction, the weight will not drop significantly, "because fat is oily and lighter." But the naked eye does look a lot thinner. "Moreover, liposuction is by no means the more the better. Professor Chen said that it is best to control the amount of liposuction at 2000-3000 ml each time, and not to exceed the safety limit of 5000 ml. Because the more liposuction, the greater the risk of surgery.
Professor Chen said that liposuction on the face and legs must be cautious. There is not much fat in these parts and it is not easy to shape. If the technology is not too hard, liposuction is easy to be uneven.
Secret 4: Liposuction has indications and contraindications.
Patients with systemic diseases, such as cardiovascular diseases, diabetes, thrombophlebitis or drug allergy, coagulation disorders, etc., are not suitable for liposuction. Women in menstrual period and pregnancy, as well as those over 55 years old and minors are not suitable for liposuction. For example, children are in the stage of growth and development, and liposuction will interfere with their normal fat development.
Secret 5: Why does liposuction kill people?
Why does liposuction lead to death? Professor Chen said that besides severe skin necrosis, the most dangerous complications of liposuction are fat embolism and massive bleeding. Fat thrombosis refers to a large amount of fat entering the blood vessels and blood circulation of human body, thus blocking the pulmonary artery, causing lung obstruction, leading to dyspnea, failure and death. "According to statistics, the death rate caused by liposuction is one in ten thousand, which has a lot to do with the experience and qualifications of doctors." Professor Chen said that experienced doctors know the distribution of human blood vessels very well and will try to avoid them during surgery to prevent accidents.
2. Side effects of liposuction to lose weight
One: regional flap necrosis after operation. If the subcutaneous fat is sucked out too much during liposuction to lose weight, which destroys the blood circulation of the skin, blisters or even necrosis of the skin may occur, leaving scars after surgery and affecting the appearance. This is mainly determined by the technical level of doctors.
Two: Delayed wound healing after operation. Liposuction wounds are usually several millimeters deep, which makes it easier to heal. However, if there is excessive injury, infection, water accumulation, etc. Delayed healing may occur, and the small scar left after healing is also obvious.
Three: numbness and abnormal sensation in the postoperative operation area. After liposuction, the skin sensation at the liposuction site will inevitably be affected, with occasional numbness and abnormal sensation such as acupuncture and ant walking, which will gradually recover after 1-3 months.
Four: the operating area is uneven. Liposuction is not absolutely uniform, so the postoperative operation area will be uneven. Mild unevenness is inevitable, and it can be gradually flattened after 1-3 months. But it depends on the skill of the doctor. If there is serious unevenness that cannot be recovered after 3-6 months, liposuction is needed again.
Five: the liposuction site is seriously asymmetrical. This side effect is caused by improper preoperative design and intraoperative operation, and it needs liposuction again.
Liposuction is not suitable for everyone. Before the operation, you need to know what the side effects of liposuction are, then weigh the pros and cons to make the right choice and find out the right way to lose weight. If you decide to do liposuction surgery, you must go to a regular hospital and choose a doctor with high technical level for surgery to minimize the side effects of liposuction and weight loss.
3. The harm of abdominal liposuction
1. Hemorrhage: There may be blood stasis under the skin after operation, which is caused by the rupture of capillaries during aspiration, and aspiration is mostly completed within two weeks.
2. Edema: Due to tissue damage and swelling of the subcutaneous part of the liquid, edema appears in the suction part, and most of them subside quickly.
3. Uneven: It is common in the early stage and will gradually improve after pressure forming.
4. Subcutaneous nodules: After the operation, some induration can be touched or the whole attraction part becomes hard, which is an inflammatory nodule formed by subcutaneous tissue injury or hematoma organized fat liquefaction, and most of them can be slowly absorbed and softened within 3 months.
