According to the recently held international obesity conference: there are more than 300 million obese people in the world, the number of people who die every year because of obesity is more than twice the number of people who die of famine and starvation. Domestic information shows: China’s 1.3 billion people, there are more than 90 million people’s weight more than the normal weight of 20%. Among them, teenagers are the most serious, 11% of primary and secondary school students are overweight, and this number is rising at a rate of 8%. If overweight and obesity are not effectively intervened in a timely manner, obesity-related diseases, especially coronary heart disease, hypertension, diabetes and stroke, will increase significantly in 10 to 20 years. Compared with the concept 20 years ago – that “general belly” is a symbol of affluence is very different, the current general view that obesity is a morbid state, abdominal obesity has become an increasingly serious global epidemic, causing widespread concern in society. Compared with non-obese people, the incidence of cerebral infarction and coronary heart disease in obese people is twice as high, the incidence of hypertension is two to four times higher, the incidence of diabetes is four times higher, and other problems such as respiratory sleep apnea syndrome, dyslipidemia, fatty liver, cholelithiasis, gout, osteoarthritis, impotence, menstrual disorders and psychological problems caused by obesity have increased significantly, and obesity has become another major health hazard after smoking. Obesity has become another major health hazard after smoking. Since obesity is a chronic disease, once formed, it is quite troublesome to treat, so prevention and early treatment should be emphasized. According to years of clinical experience, the Department of Integrative Medicine of Shanghai Huashan Hospital believes that the early prevention and treatment of obesity, in addition to diet control, moderate exercise and change of bad life behavior, combined with Chinese medicine treatment can not only effectively prevent and treat obesity, but also have long-lasting effect and basically no side effects. Chinese medicine on the understanding of obesity as early as in the ancient medical text has been recorded, “yellow emperor neijing”: “how to degree know its fat and thin? The cream, more gas and skin longitudinal slow, so can heavy belly hanging fat.” The heavy abdominal fat of the anointed person mentioned here is equivalent to abdominal obesity. The Su Wen? The strange disease theory says: “this fat and beauty of the hair also, this person must eat a number of sweet and fat, fat people make internal heat, sweet people make full in the”, “fat people, the disease of sorghum also”, is the Chinese medicine on the causes of obesity incisive discussion. We have observed clinically that in addition to overweight and increased abdominal circumference, some patients with early obesity may have shortness of breath when moving, easy fatigue, sweating, thin or greasy tongue coating; laboratory tests are mainly abnormalities in glucose metabolism and lipid metabolism, including elevated fasting or postprandial blood glucose, as well as elevated triglycerides (TG) and reduced high-density lipoprotein (HDL). These alterations are mainly disorders of substance and energy metabolism from modern medicine, and from TCM, they are dysfunctional transportation of qi, or qihua disorders. The meaning of qihua in TCM is very broad, including the digestion and absorption of food and drink, the formation and excretion of diarrhea and sweat, the generation, metabolism and transformation of essence, blood and fluid, etc. However, the most important role of qihua is to “transform essence into qi, and qi into form”, and the essence is absorbed and transformed into energy to maintain the normal metabolic function of the human body. The normal metabolism, the normal role of qihua, and decide whether to maintain the normal shape, of course, also includes the normal level of glucose and lipids in the blood. Early obesity is mainly manifested as qihua dysfunction, the patient’s digestion and absorption function is normal, but the body can not make good use of and metabolize these nutrients, accumulate in the body, resulting in the accumulation of fat in the abdomen, sugar, lipid accumulation in the blood, abdominal obesity and the rise of blood sugar and lipid level, and these factors have become the main risk factors of cardiovascular and cerebrovascular diseases. In Chinese medicine, this pathological state of qi-chemistry disorder and non-transportation is called “qi-ju”, which is caused by a combination of successive factors on the basis of positive deficiency. Insufficient innate endowment, weakness of the five organs, including the spleen, lungs and kidneys is the basis of deficiency, coupled with the acquired diet of wanton indulgence, eating more fat and sweet, sleepiness and less movement, fat people internal heat, heat depression and fire, injury and qi yin; sweet people full, congestion in the focus, dysfunction of the internal organs, spleen deficiency loss of transport, lung deficiency loss of cloth, liver depression and qi stagnation, kidney deficiency qi transformation failure, resulting in significantly lower physical consumption, excess nutrition. The body can not make good use of and metabolize these nutrients, accumulate in the body, then become wet, for phlegm, for turbidity, for a long time is depressed heat, damp stagnation, blood stasis and other mutual set, clinical appear high blood sugar, high blood fat and a series of abnormalities of sugar and lipid metabolism, fat filled in the skin and obesity. Whether it is congenital or acquired factors, in the end, it all comes from the abnormality of the qi function of the internal organs, and becomes the pathological basis of qi gathering, deficiency and reality. In view of the pathological state of obesity early qi gathering as disease, not transporting but not transforming, we established the treatment rule of attacking and supplementing at the same time, formulated the basic treatment method of benefitting qi dispersing and gathering, and formulated the effective formula of benefitting qi dispersing and gathering to prevent and control early obesity (composed of Huang Qi, Huang Lian, Ze Di, Sheng Pu Huang, etc.). The formula in the astragalus sweet warm tonic, promote the pivot, help the spleen to disperse essence for the ruler; Huanglian bitter cold, clear heat, diarrhea, dry damp for the minister; Zexie sweet cold, diuretic, damp, drain heat, help Huanglian clear heat, heat with damp go, evil go then clear qi to ascend, turbid qi to descend; raw Puhuang sweet slightly cold, blood medicine and also travel qi, the upper can clear, the lower can benefit, stagnation is feasible, is the adjuvant. The combined use of all the drugs, together with the benefit of qi to disperse the function of gathering, so that qi, blood, fluid and other essence can be normal distribution and transportation. On the basis of diet control, moderate exercise and change of patients’ bad life behaviors, we have treated a high-risk group of metabolic syndrome with abdominal obesity and insulin resistance with Yi Qi Scattering Formula in clinic. There were no adverse effects in the patients during the treatment period.
