Although the problem of obesity and its associated diseases is becoming more and more serious, except for those people who have higher requirements for appearance, most people do not care much about these, because most of the obesity associated diseases belong to chronic diseases and have a slow development process, so before the specific disease appears, the body does not feel obvious abnormalities, and naturally, it is not easy to attract their attention. However, those chronic diseases with the development of the disease, not only to the body more and more damage, treatment will also increase the difficulty, and at the same time may cause other complications, and even threaten life, and in the obesity associated with the disease there are a lot of such, such as obesity caused by stroke. Stroke (commonly known as stroke) is an acute cerebrovascular disease, if the disease is not rescued in time, there is a high probability of death or disability. The disease is mostly seen in middle-aged and elderly people, but the prevalence of the three high or obese groups increases and the average age decreases. In addition to stroke, sleep apnea syndrome and heart disease caused by obesity may also lead to sudden death, and the risk is positively correlated with the degree of obesity, the more serious obesity, the greater the probability of suffering from these diseases and sudden death. Moreover, after suffering from these diseases, whether using conventional methods to lose weight or using weight loss metabolic surgery to lose weight, there will be an increased risk. The patient’s physical condition and behavior will affect the weight loss metabolic surgery, so before the surgery, they need to give the patient a detailed examination, and also take into account the patient’s physical condition, age, living environment and other factors, and then make a personalized surgery plan based on the experience of more than 1000 cases in the past.
