Parasites (Intestinal)

Parasites (Intestinal)


Microorganisms naturally inhabit and move through the body. Some are harmless, while others cause sickness. Infections can occur when parasites make their homes in your skin, gastrointestinal tract, lungs, liver, and other organs. Parasites require a host (e.g., human cells) to live and thrive.

Parasitic infections were once thought of as a problem that existed mainly in under- developed countries. After all, diarrheal disease (from parasites and bacteria) is the great- est worldwide cause of death. Global travel has been a major contributor to the spread of parasitic infections in North America. Contaminated water and food are also major contributors. In addition, better diagnostic techniques have provided a more accurate identification of parasites and have led researchers to conclude that parasitic infections are much more common than previously thought. One laboratory that specializes in stool analysis states “almost 30 percent of specimens examined are positive for a parasite.Diarrhea and abdominal pain are the most common symptoms of a parasitic infec- tion. However, in many cases of a parasite infection, these symptoms may not be pres- ent. A whole list of symptoms and conditions could be related to a parasitic infection. Examples include loss of appetite, fatigue, constipation, depressed immunity, food allergy, fever, chills, heartburn, stomach pain, inflammatory bowel disease, lower back pain, itchy anus, rash and skin itching, hives, weight loss, arthritis, bloody stools, mucus in the stool, colitis, Crohns disease, flatulence, foul-smelling stools, malabsorption,rectal bleeding, mood changes (depression, irritability), and vomiting.

Parasites interfere with the normal activities of the cells they infect, which may lead to symptoms and disease. The secretions released by a parasite can trigger a bodily response in which the immune system attacks its own tissues. This is known as an autoimmune reaction. Examples include rheumatoid arthritis and Crohns disease. Not all parasites are necessarily harmful. Some parasites live symbiotically in the diges- tive tract. It is thought that certain parasites become a problem only when the environ- ment of the body changes. For example, dysbiosis—the imbalance between friendly and potentially harmful bacteria in the digestive tract—can lead to certain parasites becoming pathogenic (disease causing). The nutritional status of a person, as well as a compromised immune system, dictates whether a parasite can become a problem.

Parasites are commonly transmitted through food that is contaminated with fecal matter (e.g., from food preparers who do not wash their hands after going to the rest- room), waste, and the water supply.

There are many different types of parasites. Following are some of the more com- mon ones in North America.

Blastocystis hominis. This parasite is detected in a high number of stool tests.

Researchers are unclear whether it is a pathogen, because many people carry it but do not have symptoms. However, it can cause various digestive symptoms, such as cramps, nausea, weight loss, bloating, and others. It is also associated with con- ditions like irritable bowel syndrome, chronic fatigue, and arthritis.

Dientamoeba fragilis. Symptoms of this parasite, which resides in the large intestine, include diarrhea and abdominal pain.

E. histolytica. This amoeba is linked to diarrhea and a variety of digestive symptoms. Giardia. This is one of the most common parasites found in humans. It is transmit-

ted through water, in food, between children in day-care centers, via a fecal-oral

route, or through sexual intercourse. Epidemics from contaminated streams and community water systems occur every year in the United States.

Cryptosporidium. This is transmitted through contaminated food and water and from person-to-person contact. Explosive diarrhea is a common symptom. This par- asite is of particular concern for children who are HIV-positive, as their immune systems may not be able to fight off the parasite, making it a life-threatening condition.

Ascaris lumbroides. This parasite causes the most common human worm infection in the world. Infection is common in the southeastern United States. In children, it can cause abdominal cramps and malnutrition. Fecal-oral transmission often occurs via uncooked or unwashed vegetables.

Hookworm. Hookworm is not as common in the United States as in other parts of the world, yet cases do occur. It usually causes no symptoms, although a skin itch may be present. Acute symptoms can include abdominal pain, diarrhea, weight loss, ane- mia, and many others. These worms can live up to ten years. They are transmitted via direct contact with soil containing the eggs of hookworms.

Strongyloides. The eggs of these worms can penetrate the skin and migrate to the lungs and the intestines. Most infections occur via the fecal-oral route. Infected people may be asymptomatic or may have various digestive problems. Liver and nervous system infection can also be serious problems.

Trichinosis. Infection occurs from eating undercooked or processed meat. There may be no symptoms, or else nausea, abdominal cramps, fever, and muscle pain (lar- vae can invade muscle tissue) can occur.

The conventional treatment focuses on antiparasitic medications to eradicate the infec- tion. Toxicity and side effects vary for each medication.

The first step in treating a parasitic infection is to get a proper diagnosis. This is mainly dependent on a stool analysis. We highly recommend using a laboratory that specializes in comprehensive parasitology testing. Many of the stool tests done by clin- ics are not sensitive enough to pick up all of the different forms of parasites. Certain blood tests by your doctor can also help to pinpoint a diagnosis. In some cases, we treat patients for a parasite infection when they have the symptoms and the history that match a parasite infection, even though lab testing does not show a positive result. Some parasitic infections are hard to detect, but when diagnosis is uncertain, they should be treated. Natural therapies work well and should be used for a minimum of two months. One standard that many natural health practitioners follow is to treat for

Surprising Fact: Approximately  25 percent  of the worlds population is infected with hookworms. 


Surprising Fact: It is estimated  that more than 1 billion people  are infected with ascariasis  world- wide, of whom 20,000 die each year.

one additional month after the symptoms of a parasite infection have cleared. In some cases, conventional antiparasitic medication may also be required. Please note that nat- ural treatment of parasitic infections should be done under the guidance of a knowl- edgeable health-care practitioner or doctor. Pregnant women should not follow the parasitic protocol in this section.

Recommended Food

Fresh garlic, ginger, and onions are excellent as prepared foods, because they have been shown to have antiparasitic effects.
