A syndrome characterized by chronic, well-established diarrhea (greater than one month in duration) without an identified infectious cause after thorough evaluation, in an HIV-positive individual. It is thought to be due to direct or indirect effects of HIV on the enteric mucosa. hiv enteropathy is a diagnosis of exclusion and can be made only after other forms of diarrheal illness have been ruled out.
