There are several different types of parasites that can cause intestinal infections. To learn more, watch this video featuring gastroenterologist and Dr. Oz guest Dr. Robynne Chutkan.
There are three types of parasites that feast on humans:
- Protozoa - one-celled organisms that live and multiply in the blood or tissue of humans. They infect the body via mosquitoes and flies and are found in soil and water.
- Helminths - parasitic flatworms, flukes, tapeworms, thorny-headed worms, roundworms, and pinworms. They live in the gastrointestinal tract, blood, lymphatic system, and other tissues.
- Ectoparasites - ticks, fleas, lice, and mites that live on the surface of a human host and attach or burrow into the skin.
There are a host of parasitic infections that cause disease in humans. The effect can range from mildly annoying to life-threatening. Malaria is the most prevalent parasitic disease worldwide, killing more than 1 million people each year. Trichomoniasis, a common vaginal infection, is the most common parasitic infection in the U.S.
Parasites feed from inside your body. These creatures include tape worms, round worms, hook works, pin worms, that can grow to various sizes and lengths. Tape worms can attach themselves to the intestinal walls and stay nourished off food that you eat.
