Most of human adipose tissue is distributed in various parts of the body surface, forming a body shape and providing physiological functions and uses. People tend to get fat after middle age, and men tend to accumulate more fat in the abdomen and back of the neck. Women's fat mainly accumulates in thighs, buttocks, chest or arms. If it accumulates in the abdomen, it is mainly concentrated in the lower abdomen. Both men and women, when obesity is not serious, skin and adipose tissue can adjust and adapt to changes through proper stretching and contraction. If a person is obese and becomes a little less after a few years, his skin and adipose tissue will lose their original elasticity and drooping wrinkles will appear on his body. If you get fatter afterwards, this wrinkle will be hard to disappear. After repeated obesity and thinning, wrinkles will deepen and increase. On the other hand, because of obesity, the muscle tissue that plays a supporting role is slack and drooping, which will also produce wrinkles. Excessive abdominal fat can cause sagging, which not only makes people feel pain and inconvenient to move, but also causes ulcers between the folds of the skin, and has itching and irritation. Obesity can also lead to abdominal wrinkling, abdominal muscle separation and elongation, and sometimes sudden escape or illness ... There are many ways to lose weight, such as exercise, dieting, drugs and so on. , but it will add another kind of discomfort and rarely make people stick to it. Fat people in Chongqing are very concerned about weight loss methods, but few people know that surgeons can do surgery to lose weight, remove excess fat and skin, reduce heavy fatigue and change their body shape. As early as 1890, two surgeons in France reported their first abdominal plastic surgery. An American doctor reported in detail from 1899 that after abdominal skin fat plastic surgery, the number of people in Europe and America demanding this kind of surgery is increasing day by day. Later, not only abdominal fat, thigh and hip fat, skin and fat on the inner side of upper arm (weaving bat wings), but also body fat can be removed under the scalpel of plastic surgeon. Since 1963, many fat people abroad have received an operation called small intestinal shunt, which diverts the jejunum to the ileum or colon, reducing the absorption capacity of fat people and achieving the purpose of losing weight. It is reported that the fat man who has had this kind of operation can lose about half of his weight. The effect is naturally more obvious than simple local fat skin excision, but it has a greater impact on human physiology. After the operation, these fat people were asked to have plastic surgery for sagging skin because of their obvious emaciation and sagging skin. Chongqing plastic hospital
