Many people in the United States might think that parasitic infections are rare and mostly affect those who have traveled abroad. However, these infections are more common than you might expect. The CDC suggests that millions of Americans may be affected by parasites. These infections can often go unnoticed for many years because their symptoms can be similar to those of other chronic health conditions.
Symptoms of a parasite can sometimes show up as stomach problems but might also include feelings of tiredness, weight changes, lack of important nutrients, skin issues, inflammation, and changes in how the immune system works.

How Do You Get a Parasite?
The Four Most Common Routes of Parasitic Infection
- Eating undercooked meats and contaminated produce
- Insect bites
- Close contact with others
- Entry through the skin, nose, and mouth
Parasitic Infection Signs & Symptoms
Parasites can live in the intestines for a long time without causing noticeable symptoms. When symptoms do appear, they may include:
- Digestive issues such as diarrhea, constipation, or gas
- Skin conditions like eczema, hives, or unexplained itching
- Feeling tired, even after sleeping well
- Grinding teeth during sleep
- Lack of nutrients, especially iron
- Feeling anxious (possibly related to nutrient levels)
- Muscle or joint discomfort
- Itching around the rectum
Two Types of Common Intestinal Parasitic Infections
Helminths
Helminths are multi-cell parasitic worms such as pinworms, hookworms, tapeworms, and roundworms. These worms live inside the digestive system and can affect the body's resources over time.
Protozoan
Protozoan parasites are tiny, single-cell organisms that can multiply in the body and may lead to sudden health issues, like severe diarrhea and dehydration.
Functional Medicine Labs to Test for Parasitic Infection
Comprehensive Stool Test
Parasites have a life cycle and can be harder to detect depending on the day, so a 3-day comprehensive stool test is often used if there is a strong suspicion of parasitic infection. Some practitioners might use a 1-day stool sample.
The samples are examined under a microscope to look for parasites, their eggs, or signs from the immune system that a parasite might be present.

Functional Medicine Approaches for Parasitic Concerns
Different parasites may require different approaches, so getting an accurate diagnosis is important.
In conventional medicine, antiparasitic drugs, such as praziquantel and mebendazole, are often used.
In integrative medicine, some practitioners might use a combination of herbs and nutritional strategies to support gut health.
Some herbs used to support intestinal health can interact with medications. It's important to use them under the guidance of a qualified healthcare provider.
Commonly Used Herbs to Support Gut Health
- Garlic
- Papaya Seeds
- Barberry
- Goldenseal
- Oregon grape
- Anise
- Wormwood
- Black walnuts
Commonly Used Nutritional Approaches
- Consider reducing dairy, processed foods, refined sugars, and alcohol.
- Raw garlic, pumpkin seeds, pomegranates, papaya seeds, and beets have been traditionally used to support digestive health. In one study, a mixture of honey and papaya seeds was associated with changes in stool samples in 23 out of 30 subjects.
- Drinking plenty of water may help support your body's natural processes.
- Eating more fiber might help support digestive health.
- Probiotics and digestive enzymes can help maintain a healthy intestinal environment.
Things to Keep in Mind
Parasites can thrive on certain foods, so healthy digestion and proper nutrition are important. Parasites may also multiply more easily in people with imbalances in their gut microbiome or a weakened immune system.
As parasites are managed, they can release substances that might cause temporary discomfort. Working with a healthcare provider can help manage these symptoms.
Summary
Parasites might be more common than you think, and their symptoms can overlap with other health issues. If you have symptoms without a clear diagnosis, a three-day stool test might help identify these infections. Always consult with a healthcare provider for advice tailored to your health needs.
