Side effects of liposuction and weight loss surgery
1 seroma: due to repeated aspiration or aspiration in the same tunnel, the diameter of the needle tube is too large, and a dead cavity is formed under the skin, and the large cavity is filled with non-coagulation fluid, which is easy to form chronic seroma. With the formation of cyst, the fat layer of skin and deep tissue can not adhere and heal, and becomes loose and drooping under the action of gravity;

2 skin necrosis: rare, caused by damage or infection of skin nutrient vessels;

3 Skin drooping: it is mainly caused by improper selection of indications, which may be aggravated after aspiration in elderly patients and patients with poor skin texture. Patients with severe drooping should undergo skin and soft tissue resection and plastic surgery;

Infection: Most of them are caused by Staphylococcus aureus. Antibacterials should be selected according to bacterial culture and drug sensitivity test, and puncture, suction and drainage can be used if necessary;

5, swelling, cyanosis: this is caused by small blood vessel injury, which usually disappears after 7- 15 days;

6, feeling numb: this is caused by nerve endings injury, which disappears after about 20-30 days;

7. induration: This is an inevitable manifestation of the healing process of damaged tissues, which will disappear after healing. Located under the skin, the appearance is not easy to detect, it can be connected into a hard block when touched, and it dissipates in about 60- 160 days;

8. Fat embolism and fat embolism syndrome: A small amount of free fat will appear in blood and urine after operation in patients with fat aspiration volume exceeding 900ml. The incidence of FES in liposuction combined with abdominal plastic surgery is increased, which is related to excessive injury of adipose tissue. 1. Electronic liposuction: Electronic liposuction is also a new technology in the 1990s. It uses two 1.6-2.5 mm needle electrodes connected to the handle to insert into the fat layer, in which one needle automatically injects anesthetic into the liposuction site, and at the same time, a high-frequency electric field is generated between the two electrodes to destroy the redundant fat tissue of the body, and the other needle simultaneously destroys the high-density fat damaged by the electric field. The high-frequency electric field generated by the equipment has obvious destructive effect on adipose tissue, but has no great damage to blood vessels and nerves. Therefore, the amount of bleeding during the operation is small, because the operation is carried out through two small and thin electrodes, so the postoperative wound is very small and does not need suture;

2. Injector liposuction: Injector liposuction is a simple and easy operation method, which uses the negative pressure in the syringe cavity to suck out the adipose tissue at the suction site. This operation is not very complicated. Simply put, the prepared swelling liquid containing anesthetic is injected into the subcutaneous fat layer through one or several pinholes to make the fat tissue swell and liquefy, and the liquefied fat is sucked out of the body by the negative pressure in the syringe cavity. Because the needle diameter of the syringe is small and has certain specifications, the suction speed is relatively slow and the suction amount is less. However, the relatively small trauma of this operation is its advantage. This surgical method is especially suitable for liposuction in small areas, such as mandible and face.

3. Ultrasonic liposuction: Ultrasonic liposuction was first adopted by Italian scholars in 1992. Its principle is to convert electric energy into high-frequency energy through an ultrasonic generator, and generate ultrasonic waves exceeding 16kHz. Due to the loose adipose tissue and poor adhesion, ultrasonic waves have physical, chemical and biological effects on adipose tissue, which denature and rupture adipose cells and then excrete them. Therefore, ultrasonic liposuction has certain advantages: for example, it selectively destroys fat cells without damaging surrounding tissues. This also makes the patient recover quickly after operation. Only the liquid components in adipose tissue are removed, without damaging the cell membrane and matrix, so that the healed skin is easier to level off. In addition, the surgical trauma is relatively small, which is one of the advantages, but it also has some disadvantages: such as low efficiency, long operation time, and sometimes it is unbearable for patients; Because the pumped adipose tissue has been destroyed, it can no longer be used as a filling material;

4. Electric negative pressure liposuction: The operation method of electric negative pressure liposuction is not complicated, and the anesthesia method is still expanded anesthesia technology, that is, one or several small incisions are formed near the attraction site. Usually, the surgical incision is very small, about 3-4 mm, and such an incision will not leave obvious scars after healing. Through these small incisions, the anesthetic is injected into the suction site. After the anesthesia takes effect, the suction head connected to the suction device is inserted into the suction site to suck the adipose tissue in turn. Because the operation is carried out under continuous negative pressure, and the diameter of the suction head is obviously larger than that of the syringe, the speed of the operation is greatly accelerated, and the aspiration amount is also obviously increased. However, because the diameter of the suction head used is not very large, there is basically no obvious damage to blood vessels and nerves during the operation. Action one

Lie on your back, bend your knees, put your feet flat on the bed, put your hands on your abdomen, take a deep breath, and your abdomen bulges and closes.

Action 2

Lie on your back, put your hands around the back of your head, hold your chest slightly and abdomen slightly, and straighten your legs up and down alternately, from small to large, from slow to fast, for about 50 times.

Action 3

Lie on your back, hold the railing with your hands, lift your legs together, keep your knees straight, and keep your toes straight. The angle between your legs and your body should reach 90 degrees. After lifting, stop for a while and then fall, and so on until the abdomen is sour.

Action four

Put your hands on your sides, support the bed with your hands, bend your knees, pedal the bed with both feet, lift your hips as far as possible, stop after lifting, fall for 4 seconds, and then lift after rest. 1, before liposuction, be sure to communicate with the doctor, so that the doctor can have a certain understanding of your physical condition, especially your own fat distribution, which is more conducive to their making treatment plans and making the effect of the operation more satisfactory. In addition, our experts also suggest that if there is too much excess fat in the body, it is not recommended to suck too much fat at one time, otherwise.

The most remarkable feature of liposuction and weight loss surgery is that it is not easy to rebound. This operation should be done after 18 years old. Because of scientific verification, the number of fat cells in human body will be stable in adulthood. If they are still in adolescence, we are not sure about the development of cells in the body and what will happen after the operation.

3. Liposuction is a very good way to lose weight and shape, which can not only lose weight but also achieve the effect of shaping. On the 1 day after operation, the dressing was changed and elastic pants were worn. Take antibiotics orally for a week, and it will take about 10 days to reduce swelling. Exercise properly, remove stitches after two weeks, and wear stretch pants for three months, so as to maintain a good leg shape.
