Intestinal Parasites

How do I pick up Parasites? 

Microscopic eggs are excreted from the host animal or human where they are either reintroduced into the food-chain or ingested orally by the same host under fingernails for example.

Animal parasite eggs can be spread from pets through human contact or from livestock either directly in their meat or in their manure which is spread on crops and then eaten by humans. Fish are often infected with a host of water-borne parasites. It may surprize you to know that research indicates 85% of us are infected with parasites.  They are the source of many common symptoms which, left undiagnosed or treated can be responsible for many years of reduced health and well being. 

Common Symptoms of Parasites in Humans

Constipation: Some worms, because of their shape and large size. can physically obstruct parts of the digestive system. Heavy worm infections can block the common bile duct and the intestinal tract, making elimination infrequent and difficult. 


Certain parasites, primarily protozoa, produce a prostaglandin (hormone-like substances found in various human tissues) which creates a sodium and chloride loss that leads to frequent watery stools. The diarrhoea process in parasite infection is, therefore, a function of the parasite infestation, not the body's attempt to rid itself of an infectious organism.

Gas and Bloating:

Some parasites live in the upper small intestine where the inflammation they produce causes both gas and bloating. The situation can be magnified when hard-to-digest foods such as beans and raw fruits and vegetables are eaten. Persistent abdominal distention is a frequent indicator of hidden invaders. These gastrointestinal symptoms can persist intermittently for many months or years if the parasites are not eliminated from the body.

Irritable bowel syndrome:

Parasites can irritate and inflame the intestinal cell wall, leading to a variety of gastrointestinal symptoms and malabsorption of vital nutrients, particularly fatty substances. This malabsorption leads to bulky stools and steatorrhea (excess fat in feces) which is indicated by pale stools.

Joint and muscle aches and pains:

Parasites are known to migrate to encyst (become enclosed in a sac) in joint fluids, and worms can encyst in muscles. Once this happens, pain becomes evident and is often assumed to be caused by arthritis, however, Joint, muscle pains and inflammation are also the result of tissue damage caused by the body's immune response to the parasites presence.


Some varieties of intestinal worms attach themselves to the mucosal lining of the intestines tapping into the body's blood supply and leaching nutrients from the human host. If they are present in large enough numbers, they can create enough blood loss to cause anaemia.


Parasites can irritate and in some cases perforate the intestinal lining, increasing bowel permeability to large undigested molecules. This can activate the body's immune response to produce increased levels of eosinophils, one type of the body's fighter cells. The eosinophils can inflame body tissue, resulting in an allergic reaction. Like allergy, parasites also trigger an increase in the production of immunoglobulin E (IgE).

Skin conditions:

Intestinal worms can cause hives, rashes, weeping eczema, and other allergic-type skin reactions. Cutaneous ulcers, swellings and sores, papular lesions, and itchy dermatitis can all result from protozoan invasion.


Granulomas are tumour-like masses that encase destroyed large or parasitic eggs. They develop most often in the colon or rectal walls but can also be found in the lungs liver, peritoneum, and uterus.


Parasitic metabolic wastes and toxic substances can serve as irritants to the central nervous system. Restlessness, anxiety and insomnia are often the result of the systemic parasite infestation. (After completing a herbal cleanse, many people swear that their persistently grouchy mates or relatives have become a lot more pleasant and patient. "The most famous tapeworm of recent years belonged to the late opera singer Maria Callas. She had a serious weight and skin problem. When the tapeworm was detected and removed, her weight dropped, her skin improved and her temperament mellowed," says Gittleman.)

Sleep disturbances:

Multiple awakening during the night particularly between 2 and 3 AM, are possibly caused by the body's attempts to eliminate toxic wastes via the liver. According to Traditional Chinese Medicine, these hours are governed by the liver. Sleep disturbances can also be caused by nocturnal exits of certain parasites through the anus, creating the intense discomfort and itching.

Teeth grinding:

Bruxism - abnormal grinding, clenching, and gnashing of the teeth - has been observed in cases of parasitic infection. These symptoms are most noticeable among sleeping for children. Bruxism may be a nervous response to the internal foreign irritant.

Chronic fatigue:

Chronic fatigue symptoms include tiredness, flu-like complaints, apathy, depression, impaired concentration, and faulty memory. Parasites cause these physical, mental, and emotional symptoms through malnutrition resulting from malabsorption of proteins, carbohydrates, fats, and especially vitamins A and B-12.

Immune Dysfunction:

Parasites depress the body's immune system functioning by decreasing the secretion of immunoglobulin A (I&A). The infestation continuously stimulates the system response and over time can exhaust this vital defense system, leaving the body open to bacterial and viral infections.

The following conditions might also be tell-tale signs of a parasitic invasion: weight gain, excessive hunger, weight loss, bad taste in the mouth and bad breath, asthma, diabetes, epilepsy, acne, migraines, and even the biggest killers: heart disease and cancer.
