Obesity is a chronic metabolic disease that seriously harms human health, while abdominal obesity is more closely related to diseases such as type 2 diabetes, cardiovascular disease, and tumors, and has a higher risk. In recent years, traditional Chinese medicine therapy has become the choice of more and more obese patients, and acupuncture therapy is also known as a green therapy for weight loss due to its safety and no side effects. Through the analysis of the TCM physique types of obese people, it is found that Yang-deficiency constitution is one of the TCM constitution types closely related to simple obesity. This topic is based on the constitution theory of traditional Chinese medicine, and on the basis of the earlier research that has clarified the weight loss and lipid-lowering effects of electroacupuncture, it further aims at the type of yang deficiency in obese people, and clarifies the regulation and improvement of umbilical moxibustion on the constitution of obese patients with yang deficiency. In this project, patients with abdominal obesity with yang-deficiency constitution were divided into electro-acupuncture + umbilical moxibustion group and electro-acupuncture group to observe and analyze the advantages and effects of electro-acupuncture combined with umbilical moxibustion on the improvement of obesity symptoms and physical fitness of patients. The ELISA method was used to determine the metabolic indexes related to yang-deficiency constitution, to further clarify the material basis of electroacupuncture combined with umbilical moxibustion to improve the yang-deficiency constitution of patients with abdominal obesity, and to provide scientific and reasonable theoretical guidance for clinical treatment.
