Nausea and vomiting in HIV: a symptom review.

Nausea and vomiting are two of the most common symptoms experienced by those with HIV. While the causes are most commonly attributed to medication side effects, infectious causes, gastroparesis and psychosomatic, therapy aimed at controlling symptoms has not been well studied. Since nausea and vomiting have been identified as the most common cause of discontinuation of highly active antiretroviral therapy (HAART) therapy, and due to the extensive morbidity associated with these symptoms, we sought to review and discuss causes and management of these symptoms in HIV-infected patients and demonstrate the need for further research in this area. Such studies could include investigation into the prophylactic use of antiemetics with initiation or modification of HAART therapy to monitor patient compliance. In addition, anticipatory nausea and vomiting should be further studied, as it could prove to be quite prevalent, as in cancer patients.
