Endoscopy is used to find parasites that cause diarrhea, loose or watery stools, cramping, flatulence (gas) and other abdominal illness.
This test is used when stool exams do not reveal the cause of your diarrhea.
This test is a procedure in which a tube is inserted into the mouth (endoscopy) or rectum (colonoscopy) so that the doctor, usually a gastroenterologist, can examine the intestine.
This test looks for the parasite or other abnormalities that may be causing your signs and symptoms.
