Parasite Infection Symptoms

by CE Gant on December 24, 2010

Parasites evade detection and diagnosis better than most human pathogens, explaining why most healthcare professionals deny their existence or clinical relevancy. Since diagnostic tests are often falsely negative or not reliable, astute clinicians must deduce the presence of parasites. Paraphrasing Sherlock Holmes, “if all of the more likely rationales have been shown to be impossible, the remaining explanation however improbably, must be true.” In other words – once the more common causes of GI problems, such as bacterial or yeast overgrowth have been eliminated, the only possible cause of the symptoms must be parasitic.

I performed a study on 195 serial stool tests (CDSA) performed by Genova Diagnostics and found that parasites were detected on 17.9% of the samples. Now that a DNA analysis is offered by Metametrix Labs, I have found a much higher detection level. The conclusion is that parasites are a very common cause of gastrointestinal symptoms.

Complaints of chronic GI symptoms such as diarrhea, constipation, nausea, abdominal pain, bloating and gas are common. Occasionally all tests in such patients for GI functioning are normal, suggesting that something other than unfriendly flora is causing the symptoms. This used to perplex me – but not any more. Now I know that the hard-to-detect parasites are quietly skulking behind the scenes. Parasites do not seek to damage the host unnecessarily; they only want a comfortable home. Parasites often do not cause many symptoms, unlike unfriendly yeast or bacteria.

Parasites secrete toxins, some of which are toxic to the brain and can cause psychiatric and neurological symptoms. Some Integrative Medicine practitioners have suggested that the neuropsychiatric symptoms caused by parasites are reminiscent of the symptoms of “possession,” and that those infected or “possessed” by these demonic critters may have benefited by exorcism rituals, which included herbal remedies, that resulted in them being “cast out.” Not being privy to the scientific knowledge about infectious diseases, our ancestor’s healers did the best they could do with the information they had available to them.

If all diagnostic tests reveal no known cause of GI symptoms, the conventional medicine phenomenological approach can be summed up in one statement – “Symptoms just happen.” Or the symptoms will be blamed on “stress” and the patient is told that “your symptoms are all in your head.” Such ridiculous appraisals confuse many patients who are experiencing problems in their bellies, not their heads! Patients who are told their symptoms, “just happen,” are usually prescribed psychotropic drugs or symptom suppressive chemicals to alter their symptoms.

The message conveyed here – medical science can’t figure out what’s wrong with you, but just take this extremely expensive, highly profitable, very toxic chemical that living cells have never encountered before in all of earth’s history, and “I’ll see you in a few weeks.” Then the patient is advised to keep taking the chemical from now until eternity and return every few months or so to pay for another expensive office visit and refill.

So here it is straight:

All symptoms, disorders, syndromes, maladies, and illnesses have physiological causes and if the causes are not found in every patient, it is the doctor’s fault for not figuring it out, not the patient’s fault.

Since diagnostic tests are not perfect and are still relatively unreliable in the determination of parasites, and since GI symptoms are not caused by evil spirits and Freudian psychobabble, we must suspect the improbable and proceed to look for clues to implicate the unlikely culprit.

Typical telltale findings indicative of parasitic infection

1. Vague symptoms of “creepy crawling” skin irritations and itching, especially at night.

2. A disparity of lactobacillus (low) to bifidus (high) on stool testing and cultures – parasites seem to compete more with acidophilus.

3. Blood in stool – yeast and bacteria generally don’t chew their way right through blood vessel walls in the intestines, but the larger parasites are notoriously capable of doing this.

4. Unexplained anemia, due to #3 above, or low iron, TIBC (total iron binding capacity), and/or ferriten.

5. Low blood amino acid assays (blood) and low protein overall – parasites basically consume protein before you can benefit from it. If digestion is good (normal digestive enzymes in stool analysis) and intake of protein is adequate (>60 grams a day), what is preventing the protein from getting to the bloodstream?

6. Unexplained deficiencies in other nutrients such as minerals (e.g., selenium, zinc). This finding coincides with #5 above.

7. A history of anti-parasitic treatment (herbs, homepathics, medication) that improved symptoms or may have immediately worsened symptoms when they were first used. Such “die-off” symptoms with homeopathic remedies implies a clear and obvious presence of parasites.

8. A history of foreign travel or drinking water from an unusual source (such as a well at a campsite) that preceded symptoms.

9. Anal or rectal itching, AKA Pruritis Ani.

10. An unsatisfactory and unexpected negative treatment outcome with a comprehensive yeast treatment program that includes the following:

a) Total compliance by the patient;
b) A minimum treatment time of six weeks with an anti-yeast, antibiotic treatment (other than nystatin);
c) Treatment with a drug that was proven by culture and sensitivities to be effective against the particular strain of yeast or bacteria;
d) No laboratory evidence of immune dysfunction due to HIV/AIDS, immunosuppressive drugs (e.g., prednisone) or heavy metals (e.g., mercury) or other toxicity impairing immune responsiveness.

If any of these are present to any degree and unfriendly flora such as yeast and bacteria have been ruled out, parasites are the cause until proven otherwise. By deductive logic what else could it be? And since the exact parasite is often unknown, treatment must be presumptive with a broad range of anti-parasitic antibiotics, herbals and homeopathic remedies (see below).

Individuals with an intact intestinal barrier (enterocytes) are relatively impervious to parasites as with any unfriendly flora. That is why two people can drink the same water from a contaminated well and only one person develops symptoms. Or 1000 people eat contaminated beef from a burger chain and only 100 people get sick. Have you ever wondered what happens to the other 900 people that simply shrugged-off the infectious organisms? Why does there seem to be no interest at all in their resistance? This apparent oversight stems from conventional medicine’s worldview that focuses on disease rather than on wellness and prevention. Imagine the implications of failing to study 900 people who have resisted infection – information that could prevent deaths from food poisoning in the future!

Most people also believe that parasites are only a problem in undeveloped countries and the third world. Parasites have always been a problem and will continue to infest the modern world. The natural resistance that indigenous people build up to the local parasites may not offer much help in stopping the parasites that have evolved in completely different parts of the world.

Much of the food we eat no longer comes from nearby farms – it can come from the other side of the world. And the natural foods that tend to inhibit the overgrowth of parasites, such as very hot and spicy foods typically served in warmer climates (where parasites are not killed by seasonal cold spells), may not be regularly included in the diet of those living in cooler regions.

Parasites can be tiny or very large. The microscopic varieties such as Giardia are probably much more common. Conventional and hospital based labs have a very poor record of detecting parasites when stool specimens are submitted to them.

Do you have parasites?

You can start the process to find out by scheduling a phone appointment. For more information about wellness testing, see: Wellness Assessment

I think you are a brilliant man.
I have been dealing with gastrointestinal issues for 30 years and have been told all the things you have said.
Now I suffer from massive headaches, HBP and have been laid up from work with no explanation but with piles of pills.
I don’t drink or smoke.
I’m physically fit ( rock climbing, work out etc).
Instinct or paranoia brought me to you.
I am going to persist on this path until I find out.
Thank you! Thank you for writing such an empowering column.

I too have had many “Dr.s” tell me collitis, its in your head- you are imagining it… and many pills and bills later have had instinct tell me “parasites, i have been doing parasite cleanses for a few years now… because … i just know i have had these feeding off me for at least 20 years, i feel they have robbed me of my life…but i am still here so i have found peace and have been dealing with these… i have been passing thread worms, roundworms the size of my fore arm…. and now i am passing the hookworms. It has been a long battle, but i see the light at the end of this tunnel..thank you for your post.

Luckily, I live in the Washington D.C. area. I have seen some of the most highly recommended physicians and specialists (cardiologists, Electrophysiologists, Internal Medicine, Infectious Disease, Travel Medicine, Oncologists, Hematologists, Gastroenterologists, Neurologists…) in both the D.C./Arlington & Johns Hopkins (Baltimore) area for the past 3 years and no one but a lone hematologist in Arlington (from the middle east) has consistently mentioned a possible parasite infection. I have been tested head to toe several times over. Tests? I have loads of lab tests with documented abnormalities nobody has cared to put together. Even the travel medicine doctors I’ve seen never brought up parasites. I have been to some of the nastiest 3rd world countries for my work & my life style in the US includes eating sushi & pork, plus I have dogs, cats, saltwater fish, etc… as pets. Unfortunately, the hematologist has limited knowledge of parasitic infections and suggested I seek out someone who is more specialized in this area. I am going to try and make an appointment with your office & with some luck, I may be lucky to find an opening in your schedule. It’s worth a try. I think the treatment plan you mention in this post makes sense and covers all the bases.
