Liposuction surgery can achieve local weight loss in the short term, but it is not an ideal way to lose weight. Liposuction is mainly used to improve fat accumulation in specific areas and has good skin elasticity, and cannot replace healthy diet and exercise.

Liposuction removes subcutaneous fat cells through negative pressure suction, which can quickly reduce the size of stubborn fat areas such as the waist, abdomen, and thighs. The most significant effect is observed 1-3 months after surgery, but it is necessary to wear shapewear and apply pressure to shape the body. If postoperative heat balance is maintained, the characteristic of reducing the number of fat cells can make the effect relatively long-lasting. The impact of liposuction on body weight is limited, as removing 2000 milliliters of fat only results in a weight loss of approximately 1-2 kilograms due to the low density of adipose tissue. Surgery cannot eliminate visceral fat or improve obesity caused by metabolic disorders. After liposuction, the skin may appear uneven and discolored, and excessive liposuction may cause skin flap necrosis. Anesthesia risks and fat embolism may occur during surgery, and there is a probability of complications such as infection and hematoma after surgery. After liposuction, it is still necessary to control the calorie intake and strengthen exercise, otherwise the volume of remaining fat cells will increase compensatorily. Long term weight management requires establishing a low sugar and low-fat diet structure, and engaging in aerobic exercise for at least 150 minutes per week combined with strength training. For those with body mass index over 30 or diabetes, nutritional intervention and drug combination treatment should be given priority. Avoid vigorous exercise for three months after surgery, wear elastic socks daily to promote lymphatic return, and supplement high-quality protein to help repair tissues.
