9 Intestinal Parasites You Should Know and How to Protect Your Gut 

Your gut deals with a lot every day.

The food you eat. The water you drink. Your daily habits. Travel. Hygiene. Even the way food is prepared.

One thing people often forget about is intestinal parasites.

Parasites are organisms that live in or on another living thing. Some parasites affect the intestines and digestive tract. Depending on the type, they might cause diarrhea, stomach discomfort, bloating, nausea, changes in bowel movements, or no symptoms at all.

That last part is important.

Having occasional bloating or an upset stomach does not automatically mean you have a parasite. Digestive symptoms have many possible causes.

Still, knowing how intestinal parasites spread gives you practical ways to protect yourself.

Here are nine intestinal parasites worth knowing about.

1. Giardia

Giardia is a tiny parasite that lives in the intestines.

People with Giardia might experience diarrhea, gas, stomach cramps, nausea, or changes in bowel movements. Some people have mild symptoms, while others feel much more uncomfortable.

How you might get Giardia:

  • Drinking untreated water
    • Swallowing contaminated water while swimming
    • Eating contaminated food
    • Touching contaminated surfaces and then touching your mouth
    • Close contact with someone who has the infection

How to lower your risk:

Wash your hands with soap and water
Drink water from a safe source
Avoid swallowing pool, lake, or river water
Wash fruits and vegetables before eating
Take extra care with food and water when traveling
Practice good hygiene around pets and animals

If you’re hiking or camping, pay close attention to the safety of natural water sources before drinking from them.

2. Entamoeba histolytica

Entamoeba histolytica is a microscopic parasite that affects the intestines.

Some people have no noticeable symptoms. Others experience diarrhea, stomach pain, or other digestive problems.

The parasite often spreads when contaminated food or water enters the mouth.

How you might get it:

  • Drinking contaminated water
  • Eating contaminated food
  • Poor hand hygiene after using the bathroom
  • Touching contaminated surfaces
  • Certain sexual activities involving fecal exposure

How to lower your risk:

  • Wash your hands thoroughly
  • Use safe drinking water
  • Wash fresh produce
  • Keep food preparation areas clean
  • Practice safer sex

Good handwashing is one of the simplest habits for reducing exposure.

3. Cryptosporidium

Cryptosporidium is another intestinal parasite that often causes watery diarrhea.

Water is one of the important ways people become exposed. Swimming pools, lakes, rivers, drinking water, food, and close contact with an infected person are possible sources.

How you might get Cryptosporidium:

  • Swallowing contaminated recreational water
  • Drinking contaminated water
  • Eating contaminated food
  • Contact with an infected person
  • Contact with infected animals

How to lower your risk:

  • Wash your hands with soap and water
  • Avoid swallowing recreational water
  • Drink water from a safe source
  • Wash fresh produce
  • Practice good hygiene after using the bathroom
  • Take extra precautions with food and water while traveling

Remember, good hygiene matters even when the water looks clean.

4. Cyclospora

Cyclospora is an intestinal parasite that often causes prolonged or recurring diarrhea.

Some people also experience stomach cramps, bloating, nausea, or a reduced appetite.

Food and water contaminated with the parasite are common sources of exposure. Fresh produce has also been connected with outbreaks.

How you might get Cyclospora:

  • Eating contaminated produce
  • Drinking contaminated water
  • Eating food prepared with unsafe water
  • Poor hand hygiene

How to lower your risk:

  • Wash fresh produce carefully
  • Use safe drinking water
  • Wash your hands before preparing food
  • Keep kitchen surfaces clean
  • Take extra food and water precautions when traveling

You don’t need complicated routines. Good food hygiene starts with simple habits in your own kitchen.

5. Strongyloides

Strongyloides is a parasitic roundworm that eventually lives in the intestines.

This parasite has a different route of exposure from many foodborne parasites. The larvae live in contaminated soil and enter the body through the skin.

Walking barefoot in areas with poor sanitation increases the risk of exposure.

How you might get Strongyloides:

  • Walking barefoot on contaminated soil
  • Skin contact with contaminated ground
  • Contact with soil affected by human waste

How to lower your risk:

  • Wear shoes when walking outdoors in areas where exposure is possible
  • Avoid contact with contaminated soil
  • Practice good sanitation
  • Wash your hands after handling soil
  • Take extra care when working or gardening in areas with poor sanitation

For people who spend a lot of time outdoors, footwear is a simple but useful form of protection.

6. Ascaris

Ascaris is a type of roundworm that lives in the small intestine.

Infection often starts when someone swallows microscopic eggs from contaminated soil. Unwashed produce grown in contaminated soil is another possible source.

How you might get Ascaris:

  • Eating unwashed produce
  • Swallowing contaminated soil
  • Touching contaminated soil and then touching your mouth
  • Drinking contaminated water

How to lower your risk:

  • Wash your hands before eating
  • Wash fruits and vegetables before eating
  • Peel or cook produce when appropriate
  • Use safe drinking water
  • Avoid soil contaminated with human waste
  • Follow proper sanitation practices

That simple habit of washing your produce before eating deserves more attention than it gets.

7. Hookworm

Hookworms are intestinal parasites that often enter the body through the skin.

Contaminated soil is an important source of exposure. Walking barefoot in areas affected by poor sanitation increases the risk.

How you might get hookworm:

  • Walking barefoot on contaminated soil
  • Skin contact with contaminated ground
  • Spending time in areas with poor sanitation

How to lower your risk:

  • Wear shoes outdoors
  • Avoid walking barefoot in areas with questionable sanitation
  • Wash your hands after handling soil
  • Practice good bathroom hygiene
  • Use proper sanitation facilities

If you enjoy gardening, farming, hiking, or spending time outdoors, protecting your feet is a simple step worth taking.

8. Whipworm

Whipworms live in the large intestine.

Infection happens after swallowing microscopic eggs from contaminated soil or food.

How you might get whipworm:

  • Eating produce contaminated with infected soil
  • Swallowing contaminated soil
  • Touching contaminated soil and then touching your mouth
  • Poor hand hygiene

How to lower your risk:

  • Wash your hands before eating
  • Wash your hands after using the bathroom
  • Wash fruits and vegetables
  • Cook produce when appropriate
  • Avoid contaminated soil
  • Practice good sanitation

Clean hands and properly prepared food go a long way toward reducing exposure.

9. Tapeworms

Tapeworms are another type of intestinal parasite.

Certain tapeworm infections happen after eating raw or undercooked beef or pork containing the parasite.

How you might get a tapeworm:

  • Eating raw beef or pork
  • Eating undercooked meat
  • Poor food-handling practices
  • Cross-contamination during food preparation

How to lower your risk:

  • Cook meat thoroughly
  • Avoid raw or undercooked meat
  • Keep raw meat away from ready-to-eat foods
  • Wash your hands after handling raw meat
  • Clean kitchen surfaces after preparing raw meat

Safe cooking is one of the easiest ways to reduce your exposure to foodborne parasites.

Does Bloating Mean You Have a Parasite?

Not necessarily.

Bloating is common and has many possible causes.

The same goes for gas, constipation, diarrhea, nausea, and stomach discomfort.

Changes in your diet, food sensitivities, infections, medications, stress, and several digestive conditions might cause similar symptoms.

That’s why it’s better to avoid self-diagnosing based on one symptom.

If digestive problems keep coming back, talk with a healthcare professional. Proper testing helps determine what is actually causing your symptoms.

When Should You Get Checked?

Pay attention when digestive symptoms become persistent or unusual for you.

Consider speaking with a healthcare professional if you experience:

  • Ongoing diarrhea
  • Persistent abdominal pain
  • Unexplained weight loss
  • Repeated digestive problems after traveling
  • Symptoms after drinking questionable water
  • Symptoms after eating potentially contaminated food
  • Blood in your stool
  • Fever along with digestive symptoms
  • A known exposure to a parasitic infection

Getting checked is better than guessing.

You also don’t need to jump into a “parasite cleanse” because you feel bloated or tired. A proper evaluation gives you a much clearer answer.

Simple Habits That Help Protect Your Gut

Protecting yourself from intestinal parasites starts with everyday habits.

Wash your hands.

Use safe drinking water.

Wash your fruits and vegetables.

Cook meat properly.

Avoid raw or undercooked meat.

Wear shoes when walking on soil where contamination is possible.

Keep your kitchen clean.

Practice good bathroom hygiene.

Take extra care with food and water when traveling.

These habits are simple, but they make a meaningful difference in food and personal hygiene.

Your Gut Deserves More Than a Guess

Hearing the word “parasite” might sound scary.

But awareness does not need to create fear.

You don’t need to assume that every stomach problem comes from a parasite. You also shouldn’t ignore digestive symptoms that keep coming back.

Learn how these infections spread. Pay attention to your body. Practice safe food and water habits. And when something doesn’t feel right for a prolonged period, get the right evaluation.

Your gut health is built through many everyday choices.

Start with the basics.

Clean hands.

Safe food.

Safe water.

Good hygiene.

And a little more awareness about what goes into your body.
