Gastrointestinal manifestations of HIV infection

Gastrointestinal symptoms are pervasive in patients with AIDS. Organ-specific symptoms, particularly dysphagia, postprandial emesis, hematemesis, biliary colic, increasing abdominal girth, and small volume diarrhea, are usually easy to diagnose definitively and may respond to specific therapy. Thorough invasive and noninvasive investigation is warranted.
