What are the symptoms of Parasitic infections?

How are Parasites picked up?

Most people may meet a parasite at some point in their lives. They can be picked up through contaminated food or drink, foreign travel, pets, day care centers, swimming pool, lakes, and sex!

What are the symptoms of Parasites?

Many of the symptoms of parasites are similar to those experienced by patients with irritable bowel syndrome.
Parasites are a major cause of diarrhea even in developed countries such as the UK.
Additionally bloating, nausea, pain constipation, gas, fatigue and skin problems have been reported.

These symptoms may come and go due to life cycles of parasites.

What damage do Parasites cause?
In addition to some of the unpleasant symptoms listed above, scientific literature suggests that parasites may also linked to food intolerances and allergies. This is because they may cause damage to the lining of the digestive tract.

If you are experiencing any of the following symptoms you may be suffering from a parasitic infection:

Skin problems
Brain fog
Irritable bowel syndrome
Seeing worms in your stool

Some patients have picked up parasites after a trip abroad to destinations such as Egypt, Morocco, Greece, Mexico, Turkey. However parasites are very prevalent in the UK as well.

Parasite Test

We offer parasite testing via a stool test- this is non-invasive and very easy to carry out at home.

The stool test will examine the following:
Beneficial bacteria,
Yeast including Candida Albicans and Geotrichum Species
Friendly gut flora
Dysbiotic or bad bacteria

How can I order a Parasite test?

If you would like to order a parasite test, please send us your name address and date of birth and we will pleased to post you a kit. If you would rather have a consultation first, please e-mail us or call us and we can book you in.

Parasite Test
How is the Parasite test conducted?

Once you have received our stool kit, you will need to produce two separate stool samples (on separate days). We will send you vials that contain liquids to preserve you samples. Once you have completed both you will need to ship your samples back to our laboratory. The turnaround time is 2 weeks. Please discontinue probiotics or antibiotics or anti-fungals 1 week prior to doing the test.

The results take 2-3 weeks to come back and we will certainly help you interpret the results.

This above stool test is suited to patients who have frequent diarrhea with urgency or may have had exposure to contaminated food, lakes or untreated water. The Comprehensive Parasitology stool test and other Parasite Test can also help reveal candida and bacterial overgrowth.


These have proved to be a cause of people’s symptoms in 31% of the sufferers from IBS who have consulted us. They are especially likely to be a cause where the major symptoms are:

1. Diarrhoea or endless loose bowel movements;
2. Abdominal pain;
3. A lot of gurgling or churning accompanied by the first two symptoms.

If the origin of the symptoms can be traced back to a bad stomach upset experienced on foreign travel, it increases the likelihood that parasites are the problem.

Even if the patient has been treated previously by means of a parasite test on the NHS, it is still very important to do a parasite test with the American laboratory that we use because their techniques are infinitely more sophisticated and will almost certainly find parasites in circumstances where an NHS test did not.

Dientamoeba fragilis and Blastocystis hominis are the commonest parasites that we find in Britain. The former should be relatively easy to eradicate; the latter can be extremely stubborn. If you have done a stool test in the past that was negative but you feel you match all the symptoms of a parasitic infection, or you had parasites in the pasr but are wondering if you have fully eradicated them, you may like to get in touch with us to further parasite testing because:

1. We can arrange a sophisticated PCR parasite test for you; and
2. If that test proves positive, you can finally get treatments that will relieve your symptoms

Metronidazole (also known as Flagyl), for instance, is the main drug prescribed by GPs in Britain for parasites, but it does not work in a great number of cases. It also tends to produce side effects which can be just as bad as, or even worse than, the original symptoms.


The problem for patients is that GP’s just do not seem to be aware that parasites can be a major cause of IBS. Nor, for that matter, even more surprisingly do gastroenterologists.

We have just had a patient in her twenties who has had EXTREMELEY BAD IBS for ten months – so bad in fact, that she has had to be off work for the whole of that time. She has been having diarrhoea up to fifteen times a day (ten times during the day and five during the night). She had been to her GP who suggested it was due to a virus! An exclamation mark is the kindest way I can think of commenting on that particular diagnosis.... Then eventually she was sent for a colonoscopy, an endoscopy, a barium meal, and a sigmoidoscopy. So these four tests together must have cost the NHS well over £1000 (or would have cost anyone doing them privately a total of about £2,500) and would have been followed by numerous visits to consultants.

What would we have done? The moment we saw that she had given diarrhoea ten out of ten on our long questionnaire we would have immediately suspected parasites. When we audited 120 successive stool tests that we did with the American laboratory we use, we found that 31.6% of those patients had parasites. Yet GP’s and gastroenterologists seldom ever seem to consider them when they are investigating a patient with diarrhoea.

Quality Assurance
We use a number of different laboratories for parasite testing but highly recommend Doctor's Data.

The stool test is run by Doctor’s Data and utilises culture growth testing.
This is the international standard for clinical microbiology testing.
The benefit of this type of testing is that it enables susceptibility testing to be performed.
Therefore antifungals and anti-bacerials will be identified to eradicate pathogenic strains.

In addition to parasites, the test will identify 170 species of yeast of which 65 are Candida species.

The test uses:
MALDI-TOF Technology
The above shared the 2002 Nobel Prize in Chemistry and indeed is used by NASA to search for life on Mars.
In fact Doctor’s Data also introduced the above technology to the functional medicine industry.

Doctors Data is a a global company that receives more than 1400 stool samples daily from around the world!
