The purpose of this study is to investigate the clinical studies of cupping therapy for obesity in Traditional Chinese Medicine (TCM) and to evaluate the effects of it for use in practice. CNKI were searched for controlled studies on cupping therapy for obesity that were published up to September 2015. The review included 9 randomized controlled trials, and we analyzed the objectives, process of interventions, outcome measurements, and main results of the studies. We found that cupping therapy combined with acupuncture, electric acupuncture or thread embedding have more effectively decreased body mass index, waist circumference and lipid profile than acupuncture, electric acupuncture or thread embedding only have done. In the reviewed studies, cupping therapy treated in the region of abdomen, upper and lower limbs, and dorsal part operating on 5 to 25 minutes for one time with total 6 to 45 times of schedule. In this study, we demonstrated that cupping therapy combined with acupuncture, electric acupuncture or thread embedding could have effectively used for treating obesity. Further evaluation and clinical researches are required to establish evidence in practice.
