Although the essence of obesity is excessive fat accumulation, but different fat division in different locations, the degree of harm is also different, abdominal obesity is a kind of greater harm. A large number of studies and surveys show that patients with abdominal obesity have a higher probability of suffering from cardiovascular diseases, diabetes and other obesity-related diseases, which are closely related to the metabolic syndrome. It is found that the abdominal fat cells of abdominal obese patients are not only an energy reserve organ, but also a secretory organ, and they secrete a large number of pro-inflammatory factors, such as leptin, lipocalin and resistin, which can directly or indirectly participate in the inflammatory response and lead to the formation of metabolic syndrome. And in addition to metabolic diseases, the damage of abdominal obesity to the heart cannot be ignored. Abdominal obesity can cause the increase of left ventricular mass index and the decrease of cardiac diastolic function, so that the systolic and diastolic functions of the heart are reduced. In addition, abdominal obesity can also cause a variety of problems such as reduced pulmonary diffusion function and male erectile dysfunction. Abdominal obesity is an independent risk factor for metabolic diseases, and its incidence is increasing year by year in both developed and developing countries, seriously threatening everyone’s health. However, because traditional weight loss methods have little effect, the current situation of obesity remains unrelieved, perhaps only through can weight loss surgery as a surgical way to treat obese patients who are severely obese or suffer from concomitant disorders.
