Gut Bacteria Test UK
There is a new comprehensive stool test available which is proving to be of great benefit to IBS (irritable bowel syndrome) sufferers.
Called the CSA test, it stands for Comprehensive Stool Analysis test and comprehensive is exactly what it is. Patients send in stool samples and they are examined under an extremely powerful microscope to discover if they contain various substances which might be causing IBS type symptoms or digestive problems.
In my experience with patients who have taken the test, it almost always reveals at least one or two things which the NHS tests such as an endoscopy or sigmoidoscopy or a colonoscopy have not revealed. Not surprising perhaps, when you think about it, because it examines stool samples, which the other tests don't, and it takes great care to get them in a form unlike any other stool sample test. (Careful instructions are provided with the test kit sent to patients and the test can be done at home - which saves time and saves a trip to the hospital).
What is so remarkable about the Comprehensive Stool Analysis Test CSA?
The answer is the examining of no less than 25 different areas of bacteria, parasites, yeast and intestinal ecology. All are helpful because getting one's intestinal ecology right is an important step for everyone. For IBS sufferers the major areas are as follows:
PARASITES: These have been a cause of IBS symptoms in 31% of all patients who have taken the test via us. They are particularly likely to be a cause where diarrhoea or loose stools are the major symptoms and parasites are particularly likely to be present if the patient's symptoms can be traced back to a stomach bug experienced on foreign travel. Even if this stomach bug was treated with antibiotics at the time, often parasites will not have been completely eradicated and could still be causing symptoms several years later. This is particularly true if the patient was ill on a trip to India, Nepal, Egypt, South America or a similar exotic location. Even if the patient has been tested for parasites on the NHS it is very possible the CSA, because of its more sophisticated techniques, will find something the NHS test did not. Dientamoeba fragilis and Blastocystis hominis, for example, are parasites that cause IBS symptoms and are not looked for by the NHS test.
BACTERIA: Just as is the case with parasites, bacteria such as Klebsiella or Citrobacter freundii or Pseudomonas Aeruginosa can be the hidden cause of IBS. It is nearly impossible to tell from clinical symptoms if they are a cause so here the CSA is invaluable. Not only does the test reveal which bacteria are the problem, it provides a list of which drugs and/or natural remedies have been found to be the most effective at eradicating the offending bacteria.
CANDIDA ALBICANS AND OTHER SPECIES OF YEAST OVERGROWTH such as Geotrichum can be a contributory cause of IBS and the test identifies the presence of any of these yeasts (all of which can contribute to gut fermentation) and, again, provides a list of the most effective remedies.
FRIENDLY GUT FLORA, otherwise known as probiotics, are very important to a healthy gut. The test measures on a scale of one to four the presence or absence of Lactobacillus acidophilus and Bifidobacteria, two of the most important friendly bacteria which are found in natural, organic yoghurt. These are very beneficial to intestinal health and are why, just in the last few years, commercial yoghurt makers such as Yakult and Benecol have entered the market to try and persuade us all to eat yoghurt with these friendly bacteria added. Unfortunately, all these yoghurt drinks contain added sugar and so are not the best way to re-populate the gut with friendly bacteria.
The CSA also tests for occult blood in the stool, which can be due to haemorrhoids or an anal fissure, but which can also indicate the possibility of more serious pathology, such as cancer. It measures the presence of meat and vegetable fibres in the stool which are an indicator of how well the patient is digesting protein and carbohydrate and how well they are digesting fat.
My background is that of a nutritionist who specialises in food intolerances. I used to look at IBS mostly in terms of food intolerances and, believe me, they are a very important cause of IBS symptoms. But when the Comprehensive Parasitology and the CSA test became available to a small number of private nutritionists (different from dieticians, who work in hospitals), I was intrigued. Since then we have used it with every IBS patient (and those with Ulcerative Colitis and Crohn's) who does not respond to the food intolerance approach or wants to take the test immediately. In the case of those with a history of one or more stomach upsets in the course of foreign travel we recommend it at once.
To be honest, it helps almost everyone with IBS because, even if their symptoms have improved considerably from the food intolerance approach, it shows whether something is still basically wrong. We should all have one or two perfectly formed bowel movements every day. You can bet your life that everyone with really good health does. Anyone who differs from that norm can improve their health considerably with the aid of the test.
Case History: John Taylor
John Taylor was a dynamic executive in his late forties who had everything else in his life very much under control. In fact his life was probably perfect in every respect, bar one: he had had very distressing IBS symptoms for at least ten years.
John came to the IBS and Gut Disorder Centre because he'd taken a food intolerance test and he wanted our help with formulating a diet for him which avoided milk and oats, which were the two foods his particular test had shown him to be intolerant of. (NB: This does not apply to all IBS sufferers; it simply applied to John Taylor.)
In many cases very accurate identification of one's food intolerances will relieve symptoms of IBS considerably but, as I have stated in the accompanying article, there are some people who just do not respond to elimination of allergenic foods. John Taylor was one of them. So I suggested he do the CSA test and its revelations were startling. He had parasites, unusual bacteria and a very high degree of Candida albicans. So he had not just one cause of his IBS but three major ones and, in addition, a finding of a complete absence of the friendly bacteria Lactobacillus acidophilus. After appropriate treatment he has improved enormously.
