Physical examination does not contribute to the diagnosis of giardiasis. Weight loss may be evident, but no known unique physical findings are attributable to giardiasis.

On abdominal examination, patients may have nonspecific tenderness without evidence of peritoneal irritation. Rectal examination should reveal heme-negative stools. In severe cases, evidence of dehydration or wasting may be present.
