Ohio, USA, there is a woman named Mia, more than 270 pounds. One day, she quarreled with her boyfriend and quarreled in anger, Mia sat on her buttocks in a fit of rage, and sat her boyfriend to death. The police then arrested Mia, but after the trial, the judge thought that Mia was not intentional homicide, and pleaded guilty to a very good attitude, so released in court. This example is not to discuss the legal issues of sitting on one’s buttocks, but to analyze from a medical point of view what health risks exist in obese people who can sit on each other to death. You know, in real life, excessive body obesity will not only endanger others, but also endanger themselves. According to one survey, the number of deaths due to obesity increases between 111,999 and 365,000 per year. Obesity reduces life expectancy by an average of 6-7 years, with severe obesity (BMI>40kg/m2) reducing life expectancy by 20 years for men and 5 years for women. So, although Mia has not been sentenced by law, she has fallen into the mud pit of obesity that is at stake. Obesity can cause type 2 diabetes, hypertension, hyperlipidemia, cardiovascular disease, arthritis, infertility, sleep apnea syndrome, etc. Obesity is like Pandora’s box, once opened there are a variety of “associated diseases” to take advantage of the opportunity to come out, a serious threat to life and health. Therefore, only by choosing a scientific and reasonable weight loss method can we close the box and ensure our quality of life and physical and mental health. For the severely obese, weight loss surgery is currently the treatment of choice for a large base of people, and after more than 70 years of development, the medical community believes that this surgery is the only long-term effective method of treating obesity. Bariatric surgery addresses the root cause of food intake and nutrient absorption, not only reducing weight, but also treating a variety of metabolic diseases associated with obesity, achieving multiple benefits in one stroke.
