Obesity is now a key concern in the medical community, and many non-communicable chronic diseases are closely related to obesity. Many doctors advise patients to reduce their weight (diabetes, hypertension, polycystic ovary syndrome, etc.) when they visit them. The issue of “obesity is a disease” is not recognized by the public, and only when the disease comes will they go to cure it. More people will choose to cause the disease, but ignore the harm brought by obesity to the body. Although the disease is controlled, the weight is not lost, and it continues to damage the body’s functions and endanger the patient’s health. There is a survey: “If there is no mass murder of human beings, the world problem of obesity will continue for another 50 years.” The medical community is concerned about the problem of obesity, but the public ignores it. Because fat is not a disease! Instead, people are more concerned about the diseases brought by obesity (such as “three highs”, diabetes, coronary heart disease, arthritis, sleep apnea syndrome, polycystic ovary syndrome, etc.). Nowadays, many businesses support obese people and encourage them to eat more when they advertise. I would like to say that sometimes eating these extra bites seems to take advantage of, but ruin the body. There are statistical results that for every$1 spent on weight control, you save yourself$8.50 in treatment costs, while potentially saving yourself$100 in resuscitation costs. Many patients are determined to have surgery because they have diabetes. They have also had other metabolic diseases such as hypertension, fatty liver, sleep apnea syndrome, and polycystic ovary syndrome before they were admitted to the hospital. After the surgery, not only did they have good control of their blood glucose, but also many of their conditions were substantially relieved. Some of the patients jokingly said, “It is really a thin solution for a thousand sorrows”. Because there are many such cases around me, I know more about the horror of obesity. Now that I have reached middle age, my BMI is slightly above healthy levels, which makes me very afraid to step up my weight control. Obesity should not only be a medical concern, but also a problem that everyone is aware of, if the BMI is over 25, then the weight is already becoming a burden.
