There is no absolutely painless surgery, no matter what kind of liposuction is used, anesthesia must be implemented. Surgery will cause intraoperative pain due to injection of anesthetic, insufficient and uneven anesthesia and low anesthetic concentration. Under normal circumstances, the pain is not obvious within 24 hours after operation, and then you will feel sore, and the pain will be aggravated when you apply local force. Generally, it gradually decreases and disappears after 3 days of operation. If the situation is the opposite, pay attention to whether there is infection, hematoma or seroma in the liposuction area. Pay special attention to whether liposuction damages limbs.

2. Bleeding

Liposuction can damage capillaries and small blood vessels, leading to bleeding. At present, due to the use of swelling agent, the operation is correct, and the amount of bleeding is very small, most of which is within 100 ml, and blood transfusion or infusion is not needed. There is a small amount of blood in the postoperative fluid, which can be significantly reduced after 24 hours, so don't worry. If the patient's coagulation function is not good, or the doctor's rough operation damages more blood vessels, it will also increase bleeding.

3. Dizziness, nausea, trembling and syncope

A few patients are caused by mental stress, and most of them are postural hypotension caused by long operation time, large liposuction range, large absorption of anesthetic, more bleeding and sudden standing. At this time, you should lie flat on the bed to avoid sudden lifting, which can be relieved in a moment. If the reaction is serious, you should contact a doctor as soon as possible for timely treatment.

4. fever

Some patients may have fever after operation, generally not exceeding 38.5℃. This situation mostly occurs in patients with large liposuction range and large liposuction amount, but it only occurs within 3 days after operation and generally lasts for 1 ~ 2 days, so it can be treated symptomatically. However, if the patient still has fever with local redness, swelling, heat and pain 1 week after operation, it is necessary to consider the possible infection and report it to the doctor in time.

5. Subcutaneous hyperemia

Most patients will have subcutaneous congestion after operation. Generally 1 ~ 2 weeks can be absorbed.

6. Hematoma, edema and seroma

Hematoma is caused by concentrated bleeding after vascular injury and improper postoperative compression bleeding. Edema is due to the reaction after tissue injury or the pressure of dressing on the blood vessels in the operation site, which leads to poor venous blood return. Seroma is caused by poor drainage of body fluids and uneven compression. Hematoma and seroma can disappear after proper dressing. Edema can slowly disappear, and if the blood vessels in the surgical site are compressed, the pressure in the site can be reduced.

7. Skin changes

Most of them are caused by too thick instruments, too shallow liposuction, less subcutaneous fat, uneven dressing pressure, etc., and most of them occur in the abdomen because the abdomen often flexes. It can be prevented by improving the liposuction tube and retaining appropriate subcutaneous fat. Adjustable bandages for uneven or flexible parts can be recovered in a few days.

8. Depression deformity

Mainly due to lack of operating experience and excessive liposuction in the local area.

9. Skin blisters

(1) Because liposuction is too thin, it damages the subcutaneous vascular network and affects the blood supply to the skin. (2) Excessive local compression affects blood flow.

(3) Allergy due to the use of adhesive tape. Blisters on the skin should be treated by a doctor in time.

10. The skin is numb, itchy and stiff.

Temporary numbness is the effect of narcotic drugs. Numbness within 1 month after operation is caused by liposuction. Generally, it begins to recover gradually on 10 day after operation, and itching may occur during the recovery process. Skin hardness is the process of repairing liposuction area, which can be softened in 3 ~ 8 months.

1 1. Rebound

Fat in many parts of the body is divided into two layers, deep and shallow. If the deep fat is removed, only 0.5 ~ 1 cm remains, and the deep fat will not rebound locally. The reason for the rebound is that the local liposuction amount is insufficient, and there is no regular diet and exercise after liposuction. Some patients mistakenly think that all parts of the body will not gain weight after liposuction, and they will eat and drink, which is absolutely unacceptable. You know, if you don't pay attention to scientific diet and exercise, the parts without liposuction will still get fat.

12. Skin relaxation

The skin of most young and middle-aged patients retracts elastically after liposuction, and there will be no skin relaxation. For people who show apron-like skin relaxation before liposuction, it is safe and effective to remove loose skin after liposuction.

13. Breastfeeding

Some people have lactation after liposuction in the upper body, which is caused by excessive absorption of swelling agent in the breast. It appears 2 ~ 3 days after operation and can heal itself.

14. Incision scar

Any operation has traces, just because the doctor's skills and personal physique are different, and the size and degree of incision marks are different. If it is difficult to find hairsprings, some are like red beans or even broad beans. After operation 1 year, it can be softened slightly, and if it is still obvious, it can be removed.

15. Muscle injury syndrome

It is because the liposuction device is mistakenly inserted into the muscle layer under the deep fascia, especially the calf, which will cause the muscle fiber to break and bleed. Due to the wrapping of myofascia, bleeding is not easy to be discharged, and the pressure in myofascia increases, compressing nerves and blood vessels, which can affect nerve and muscle functions, resulting in severe pain and limited activity. This is often caused by the operator's inexperience and rough movements. In this case, you should see a doctor immediately.

16. Serious complications

There are complications such as hemorrhagic shock, fat obstruction, abdominal wall perforation, intestinal rupture, etc., which can lead to death in severe cases, but these situations are extremely rare.
