Sixty percent of patients with human immunodeficiency virus (HIV) in the United States and 90% throughout the world will have diarrhea at some point in their illness. This article provides an introductory exploration and discussion of Western and Eastern perspectives of chronic diarrhea in patients with HIV. Western etiologies and treatment approaches, as well as Eastern views from traditional Chinese medicine pathogenesis and treatment principles involving acupuncture and moxibustion are presented. Whereas their interpretations of the causes of diarrhea are different, both the East and West have something to offer patients with this distressing symptom. Further exploration and clinical research is needed in this area.
