Intestinal Parasites (Protozoan)

Your exam shows that you have a tiny intestinal parasite. It can only be seen with a microscope. Giardia and cryptosporidia are the two most common protozoan type intestinal parasites. They are usually spread through contaminated food and water.


These parasites may cause symptoms that can last for weeks. These include:

  • Abdominal cramps.

  • Diarrhea.

  • Bad smelling stools.

  • Bloating.


Fresh stool samples must be checked for parasites and their eggs. This may need to be repeated several times to find the parasites.


Antibiotic treatment for 5-10 days may be needed to get rid of some of these parasites. Please see your caregiver for a follow-up exam to be sure you are cured, or if your symptoms are not improved after several days of treatment.
