Frequently, patients with gastrointestinal parasitic infections do not have any signs and symptoms that are specific for parasitic infections (eg fever, malaise, fatigue, sweating, wt loss, anorexia, edema, pruritus).
Some patients may be asymptomatic.
Gastrointestinal symptoms, if present, include diarrhea, abdominal pain, dysentery, flatulence, jaundice, rectal prolapse, dyspepsia, malabsorption, vomiting and biliary colic.
