Nowadays, as work gets busier and busier, the lunch time is very short and fast food culture is becoming more and more popular. Just like Burger King, a large double-decker burger for $9 is a quick fix for a lunch, and with such a high-calorie diet piling up, fat people are showing a rapid multiplication of growth. The United States has long identified this problem, they also conducted research and found that in the past 10 years, the proportion of obese adults increased by 50%, and currently about 50% of American adults are suffering from overweight. And the proportion of obese children in the United States, the 10-year period has increased nearly 1 times. In the world, some people count about 50 million men and 60 million women belong to the obese bloated body. I wonder if anyone in China has done a similar survey. According to the data released by the domestic authorities, in China’s cities, secondary and elementary school students weighing more than the standard weight abound. Then what are the factors caused by obesity? 1, the standard of living improved, the body ingested too much energy (excess nutrition): born after the 1980s children, I’m afraid they have never heard of “melon and vegetable generation, two thin, a dry” such a statement. The only foods that stick out in their minds are probably high-energy foods like chocolate and McDonald’s. But they may not know that a burger is a good idea. But they may not know that a hamburger, a package of fries and a milkshake together contain about 4,000 kilojoules (about 956 kcal) of energy, equivalent to more than half of the total daily energy needs of a normal adult, if at the same time a fried chicken leg, the body’s energy intake is even more significant. Even for those adults who know these past events, with the improvement of living standards, the life of a meat and wine every day is not too difficult for everyone. So to speak, the improvement in quality of life, a little carelessness, followed by the disadvantages of over-nutrition. 2, the standard of living, the amount of exercise (activities) to reduce: what used to talk about “100 steps after dinner, live to 99”, but nowadays can not even forget to watch TV during meal time. The time spent doing laundry has also become the time spent watching TV, but there are only 24 hours in a day, sitting for a long time, the time to move is naturally reduced, just eat without doing, there is no reason not to gain weight. The result of the increase in daily energy intake and the decrease in energy consumption of the body, I believe we do not say, we all understand, will undoubtedly be accompanied by more and more obese body shape. The development of bariatric gastric bypass surgery: In 2004, China first introduced “bariatric gastric bypass surgery”, but in the long-term clinical treatment found that, although the “gastric bypass surgery” treatment effect is good, but it will be rejection for a small number of people, making the treatment effect It is difficult to improve the treatment effect. Due to the different physical constitution (Westerners are tall and fat, while Asians are short and thin) and dietary differences (Westerners have a high-fat, high-calorie diet), obese patients also have differences in obesity complications and surgical tolerance, etc. If the “gastric bypass” treatment is completely copied from the West, it will inevitably cause If the treatment is completely copied from the western “gastric bypass”, it will inevitably cause “unconventional”. In response to the physical characteristics of Asian people, especially Chinese obese patients, experts in domestic hospitals have upgraded and improved the design of “gastric bypass surgery”, and the modified “gastric bypass surgery” (also called Chinese “gastric bypass surgery”) is now available. Gastric bypass surgery” (also known as Chinese “gastric bypass surgery”) was thus born. Gastric bypass surgery: 65%-80% of the overweight portion of the body weight can be lost.
