With the progress of society, economic development, improvement of people’s living standard, especially the change of lifestyle, the incidence of obesity, hypertension, diabetes, dyslipidemia and other “diseases of affluence” in the spectrum of human diseases has increased sharply. Moreover, the prevalence of preexisting pathologies associated with each disease (overweight, high normal blood pressure, high fasting glucose and abnormal glucose tolerance, borderline elevated cholesterol, triglycerides and LDL) has increased significantly. These diseases now have a unified name, called metabolic syndrome, so that we can have a comprehensive understanding of related diseases, “a glimpse of the whole panther”, to avoid “a leaf blind, not see the forest”. At the same time, the incidence of cardiovascular and cerebrovascular diseases, which are closely related to the disease, is also increasing, seriously affecting the daily lives of patients and constituting a serious social and public problem. What is even more frightening is that these diseases are becoming as epidemic as, or even more powerful than, infectious diseases, and their onset is getting younger and younger. Throughout the development and evolution of metabolic syndrome, from early overweight and obesity, followed by hypertension, hyperlipidemia, diabetes and other diseases, and with the prolongation of the disease, many complications will appear, making the condition more complex and changeable, and more difficult to treat. The components of the metabolic syndrome are like killers, coveting our health at any time. Among them, obesity is called the bloated killer, not only affects the beauty, but also is the breeding ground of other “rich diseases”, its health risks are no less than tobacco poisoning, as the core of the metabolic syndrome, will become a serious problem of human health in the 21st century. Hypertension is known as the silent killer, silently lurking in your side, seemingly “with the wind into the night, moist things silent” of the situation, but the actual “stone through the air, the waves lapping the shore” of the momentum, killing people in the invisible. Diabetes is known as a sweet killer, like a sugar-coated cannonball, once hit, many people suffer from it, but can not stop. Dyslipidemia is known as the greasy killer, just like the sediment in the river, slowly clogging our blood vessels, if we can’t clear the silt in time, the consequences are endless. At the same time, these diseases are inextricably linked to each other, and can often co-exist, cause and effect, and aggravate each other. If these four diseases exist together, the danger increases greatly, and some people have imaginatively called it “death quartet”. And obesity is the “culprit”, is the cause of cardiovascular disease and other chronic complications of the culprit, and has the human health “number one killer” called cardiovascular disease is the main cause of disability, death. They are the enemies of human health, and their harmful effects must not be underestimated. However, unfortunately, some people know very little about the prevention and health care of these diseases, and some are even completely unaware of their harmful effects, not enough attention, resulting in some people until serious complications have occurred after the awakening, but it is too late; there are a few people are disabled, and even death. The famous saying “prevention is better than cure” speaks to the importance of prevention. About 50% of the “diseases of affluence” can be prevented. In addition to genetic factors, these diseases are often related to lifestyle, so prevention is better than cure, better than cure, prevention is better than cure, prevention is more important than cure, to achieve early prevention, early detection and early treatment of diseases. The prevention and control measures should include: first, from the source, starting with changing the bad lifestyle, adopt a healthy lifestyle (including a reasonable diet, moderate exercise, quit smoking and limit alcohol, psychological balance); second, for those who already suffer from the above diseases, should be early, active and effective treatment, “prevention and cure”, “to mend the fold. “mend the fold after death, it is not too late”. This will not only prevent the further development of these diseases, and it is entirely possible to make these patients live, work, study and live a long life as normal people, and some early patients can reach the standard of cure.
