How to Tell If You Have Intestinal Parasites and What to Do About That

Many people believe that intestinal parasites exist only in underdeveloped or impoverished countries. While it is true that these infections are more common in regions with poor sanitation, they are far from rare in developed nations. In fact, parasite exposure can happen almost anywhere. It’s an unsettling thought to imagine hosting a colony of parasites, yet millions of people experience it—often without realizing it. According to the World Health Organization, more than three billion people worldwide suffer from some form of intestinal parasitic infection, and a significant portion of them live in developed countries with modern healthcare systems.


What Are Intestinal Parasites?

Parasites come in various forms, but the two major categories of intestinal parasites are helminths and protozoa.

  • Helminths are multicellular worms that cannot reproduce inside the human body. Common examples include tapeworms, pinworms, and roundworms. While they don’t multiply internally, they can grow quite large and cause a range of symptoms.

  • Protozoa are single-celled organisms that can multiply within the human body. This ability often makes them more dangerous, as they can spread quickly and lead to severe infections if left untreated.

Some parasites cause immediate symptoms, while others may stay dormant or cause chronic issues that mimic more common conditions. This makes diagnosis more challenging, especially in regions where parasite infections are not routinely considered.


How Do You Contract Intestinal Parasites?

The most common method of transmission is contact with infected feces. This may occur through:

  • Contaminated soil

  • Contaminated food or poorly washed produce

  • Unsafe or untreated water

  • Eating undercooked or improperly handled meat and fish

Your risk rises in certain situations such as:

  • Traveling to countries with known parasite prevalence

  • Poor hygiene or inconsistent handwashing

  • Weakened immune function

  • Handling animals or living in close proximity to them

  • Being very young or elderly, as these age groups are more susceptible

Once infected, parasites can be easily spread to others through contact or shared surfaces, which is why hygiene plays such a crucial role in prevention.


Why Are Intestinal Parasites Dangerous?

Parasites survive by feeding on nutrients inside your body. Although high-hygiene environments reduce the severity of infections, they can still cause notable health problems.

When the intestines become a host, even the stomach’s naturally high acid levels may fail to kill the organism. Your immune system responds immediately, often resulting in inflammation and discomfort.

Severe or long-term infections may cause:

  • Nutrient malabsorption, leading to fatigue, anemia, and weakened immunity

  • Toxin release into the bloodstream and lymphatic system

  • Bowel obstruction, where parasites block the intestinal passage

  • Intestinal bleeding, contributing to iron-deficiency anemia

One of the biggest challenges is that there are hundreds of parasite species, each capable of causing different symptoms. Many of these symptoms are not strictly digestive, which is why parasite infections are commonly overlooked or misdiagnosed.


Key Symptoms of a Parasite Infection

Here are common indicators that may suggest a parasitic infection:

  1. Excessive food cravings or loss of appetite

  2. Unintended weight loss

  3. Abdominal pain

  4. Digestive disturbances: diarrhea, constipation, gas, or IBS-like symptoms

  5. Blood sugar fluctuations

  6. Skin problems: itching, rashes, or irritation

  7. Anxiety, mood changes, or depression

  8. Sleep disturbances

  9. Muscle or joint pain

  10. Chronic fatigue or poor stamina

  11. Iron-deficiency or anemia

  12. Frequent infections due to weakened immunity

  13. Reduced libido

  14. Bloody or pale-colored stool

  15. Nausea or vomiting

  16. White specks in stool

  17. Sulfur-smelling burps

It’s also possible for symptoms to come and go, making them easy to dismiss or attribute to unrelated issues.


How to Treat Intestinal Parasites

Treatment can involve either conventional medicine or alternative approaches, although it’s best to consult a healthcare professional before starting any treatment plan.


Conventional Medicine

If you suspect a parasitic infection, a doctor can order a stool test or other diagnostic analyses. Prescription antiparasitic medications—including albendazole, mebendazole, or metronidazole—are highly effective and usually act quickly.


Alternative and Complementary Approaches

1. Herbal Remedies

Some commonly used anti-parasitic herbs include:

  • Garlic

  • Goldenseal

  • Barberry

  • Anise

  • Oregon grape

  • Wormwood

  • Wormseed

  • Black walnut

  • Mint varieties

  • Cloves

  • Oregano

  • Thyme

  • Olive leaf

Always consult a healthcare provider before taking herbal supplements, as they may interact with medications or may not be suitable for everyone.


2. Supplements

  • Probiotics (such as Lactobacillus and Bifidobacteria) help maintain a healthy gut environment, limiting parasite survival.

  • Digestive enzymes support normal intestinal function. Papain, a papaya-derived enzyme, may help disrupt parasitic worms.

  • Vitamin C strengthens the immune system.

  • Zinc supports immune health and may help the gut lining recover from inflammation.


3. Homeopathic Treatments

Homeopathic options sometimes recommended include Cina, Spigelia, Indigo, Teucrium, Sabadilla, and others. A trained practitioner should guide these treatments.


4. Dietary Support

Certain foods may help discourage parasites:

  • Raw garlic

  • Pumpkin seeds

  • Papaya seeds

  • Pineapple

  • Carrots, beets, pomegranates

Other helpful guidelines:

  • A mix of honey and papaya seeds may help flush the intestines.

  • Increasing dietary fiber supports natural elimination.

  • Avoid refined sugars and simple carbohydrates that parasites thrive on.

  • Drink plenty of water.

  • Temporarily avoid coffee and alcohol, which may irritate the gut.

  • Eat foods high in beta-carotene like sweet potatoes and squash.

  • Include spices such as turmeric and cloves for their antimicrobial properties.


5. Intestinal Cleansing

Some people choose colon detoxes involving:

  • Psyllium husks

  • Bentonite clay

  • Activated charcoal

  • Citrus pectin

  • Pumpkin seeds

  • Papaya extract

  • Flaxseed

These methods aim to remove toxins and help restore gut balance.


6. Food-Grade Diatomaceous Earth (DE)

Food-grade DE is sometimes used as a natural way to eliminate parasites. Some studies suggest DE may help reduce parasite load in animals, which has encouraged its use among humans. It is essential to use only food-grade DE and consult a professional before trying it.


Preventing Parasitic Infections

Since parasitic infections are highly contagious, prevention is key:

  • Wash hands thoroughly after using the restroom and before handling food.

  • Clean fruits and vegetables carefully.

  • When traveling, be cautious with drinking water, ice cubes, and raw foods.

  • Maintain good hygiene for yourself, your home, and your pets.

Good sanitation practices significantly lower the risk of infection and reinfection.
