Objective: To observe the efficacy of unblocking and regulating the Belt Vessel acupuncture method for patients with abdominal obesity in Germany and its influence on the body fat parameters and glycolipids metabolism. Methods: A total of 82 cases of abdominal obesity in Germany were selected. There were two dropout cases in the treatment process. All of the patients received acupuncture at Daimai (GB26), Daheng (SP15), Tianshu (ST25), Zhongwan (CV12), Shuidao (ST28), Waiguan (TE5), and Zulinqi (GB41). The patients received acupuncture therapy once every 2-3 d, 3 times a week. The treatment duration lasted 4 weeks. Before and after treatment, the body mass (BM), waist circumference (WC), abdominal circumference (AC), hip circumference (HC), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and fasting blood glucose (GLU) were measured respectively, and the body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and body fat rate (BFR) were calculated. Results: After treatment, the total effective rate was 72.5％; the levels of BM, WC, AC, HC, BMI, WHR, WHtR, BFR, TC, LDL-C, and GLU declined significantly compared with those before treatment (P<0.01), while the TG and HDL-C slightly declined, but the differences were statistically insignificant (P>0.05). Conclusion: The unblocking and regulating the Belt Vessel acupuncture method can significantly reduce body fat parameters such as BM, AC, and BFR, and correct the disorders of glucose and lipid metabolism in patients with abdominal obesity in Germany.
