Giardiasis

Parasitic disease that results in diarrhea

Giardiasis

Giardiasis is a parasitic disease caused by the protist enteropathogen Giardia duodenalis (also known as G. lamblia and G. intestinalis), especially common in children and travelers. Infected individuals experience steatorrhea, a type of diarrhea with fatty sticky stool; abdominal pain, weight loss, and weakness due to dehydration and malabsorption. Less common symptoms include skin rash, hives and joint swelling.
