Although the safety of liposuction technology is improving, the risks of liposuction surgery still need to be paid attention to, not everyone can have liposuction, and some people are not suitable for liposuction. As a beauty lover, liposuction requires rational consumption, and health and safety are equally important. 1, minors under the age of 18 should not be liposuction, because the number of fat cells in adults can only be constant and not easy to rebound after surgery, and liposuction has an impact on the endocrine system of minors, which may affect the development of the body, except for the case of breast development in boys. 2, pregnant and lactating women need sufficient nutritional supplements, and anesthetic agents will have unpredictable effects on the fetus or baby, so women should not go for liposuction in this period. 3, with the development of the times, the demand for beauty of the elderly is increasing, but the elderly should choose the appropriate plastic surgery projects, liposuction is not suitable, because with the increase in age, the elderly skin elasticity decreases, the skin is difficult to return after surgery, may need to remove the skin of the fold repair, and the elderly also have a lower tolerance for surgery. 4, patients with high blood pressure, heart disease should not liposuction, because the swelling fluid contains epinephrine, has a blood pressure effect, for patients with cardiovascular disease has a potential risk. 5, the amount of liposuction should not be too much each time, generally the amount of fat suction is 3000 to 5000 ml, because too much liposuction will cause the loss of electrolytes and protein and disorders in the body, crossing the tolerance limit of the body, which may lead to life-threatening complications such as shock. 6, liposuction should be moderate, not skin and bone, fat itself plays a positive role in the body to store energy, isolate cold, slow down the impact, fat is different from tumor, can not be completely removed, and obesity is mainly caused by deep fat cells hypertrophy, so the surgery should save the shallow fat, so as not to cause skin hematoma and necrosis. 7, liposuction and weight loss are different, the accumulation of visceral fat caused by obesity cannot be solved by liposuction, some people think that they can continue to eat and drink after liposuction and then go back to liposuction, this idea is wrong, liposuction focuses on shaping, for health consideration, the pressure of fat on cardiovascular system should be relieved by scientific weight loss. In conclusion, health is the yardstick for choosing liposuction surgery, and beauty seekers should treat it rationally and pursue beauty and safety first.
