Is liposuction effective for weight loss

Liposuction weight loss can usually quickly reduce local fat accumulation, but it cannot replace healthy weight loss methods. Liposuction surgery is mainly suitable for improving stubborn fat accumulation in areas such as the abdomen and thighs, but its effect on systemic obesity is limited. Liposuction surgery removes subcutaneous fat cells through negative pressure suction, and the number of fat cells is non renewable after surgery, resulting in a long-lasting local shaping effect. But surgery cannot change the volume of fat cells. If postoperative calorie intake exceeds consumption, the remaining fat cells will still expand, leading to weight gain. The surgical effect is closely related to the doctor's operating technique, and excessive suction may lead to uneven skin or hematoma. After surgery, it is necessary to wear shapewear for 1-3 months to help the skin retract, and complete recovery takes 3-6 months. The weight loss after liposuction usually does not exceed 5 kilograms, mainly improving body circumference rather than weight values. Liposuction surgery carries certain risks, including anesthesia accidents, infections, fat embolism, and other serious complications. Patients with cardiovascular disease, diabetes or coagulation dysfunction should not be operated. Temporary sensory abnormalities, skin laxity, or pigmentation may occur after surgery. Multiple liposuction may damage the subcutaneous vascular network and affect skin blood supply. In rare cases, deep vein thrombosis or organ perforation may occur. The surgical effect is limited by individual skin elasticity, and patients with loose skin need to undergo abdominal wall plastic surgery and other surgical procedures. To maintain the effectiveness of liposuction, it is necessary to adhere to a low-fat diet and regular exercise for a long time, with a daily calorie intake controlled at 1200-1500 calories, and 150 minutes of aerobic exercise combined with strength training per week. It is recommended to choose a reputable medical institution, conduct a comprehensive evaluation of cardiopulmonary function and coagulation indicators before surgery, and follow the doctor's advice to use elastic bandages and have regular follow-up visits after surgery. After liposuction, high-quality protein should be supplemented to promote tissue repair, and vigorous exercise should be avoided for at least one month to prevent wound dehiscence or delayed healing.
