The SIBO breath test (Small Intestinal Bacterial Overgrowth) is also an excellent test that is now available and is also of tremendous benefit to IBS sufferers.


SIBO stands for Small Intestinal Bacterial Overgrowth and refers to a condition in which there are extremely large amounts of bacteria present in the small intestine (at least 100,000 bacteria per ml of fluid). SIBO is defined as an increase in the number in the upper gastrointestinal tract. Unfortunately large amounts of bacteria should not be present in the small intestine. In fact, in a healthy individual, the body will try and remove large concentrations of bacteria from the small intestine using a migrating motor complex, MMC to sweep out the bacteria.

SIBO Symptoms
:
The main symptoms of SIBO are similar to IBS- they include:
Belching, Burping, Diarrhea, Malabsorption, Gas, Flatulence and Constipation.
Many patients are unable to tolerate very healthy foods including broccoli, beans, lentils, onions and garlic.

What are the Causes of SIBO?

There is a still a lot that is unknown however SIBO may be caused by:
1) Use of PPI's (Omeprazole/Lanzaprozole) as the latter are designed to suppress stomach acid and may cause bacterial overgrowth.
2) Food poisoning- Acute Gastroenteritis
3)Achlorhydria (lack of Hydrochloric acid)- this may be due to long-term use of proton pump inhibitors, see 1- as the latter cause bacterial overgrowth in the duodenum and stomach. Proton pump inhibitors also accelerate intestinal transit- diarrhea.
4) Pancreatic exocrine insufficiency, (lack of pancreatic enzymes)


How can I do a SIBO test-
If you would like to do a SIBO test, please contact us by e-mail- [email protected]

or by phone - 0345 1297996 and we can arrange a kit to be sent to you. Careful instructions will be included with the test and your results will take 2 weeks. If you would rather have a consultation with us first that is often a very good idea to make sure SIBO is the appropriate test for you.

We recommend using a lactulose breath test or a hydrogen breath test, however we do offer glucose testing as well.

The SIBO test is a breath test that will measure Methane and Hydrogen- these are gases that will be produced by bacteria in the small intestine.


In my experience, at least 40% of patients who have IBS and have taken the SIBO test do test positive for SIBO.

There has also been a study conducted by Dr. Mark Pimentel and published in The American Journal of Gastroenterology that claims 84% of IBS patients have abnormal lactulose breath tests and were diagnosed with SIBO.


The NHS still does not test routinely for SIBO, but it is certainly worth investigating if you have been diagnosed with IBS.


What is the treatment for SIBO?


The answer is the reduction or elimination of bacteria. Herbal remedies including oregano, grapefruit seed, lemon balm can help and following a fairly strict diet for 4-8 weeks will be needed to starve the bacteria. The low-fodmap and SCD (Specific carbohydrate diets) and Elemental diet are often used for SIBO. We can certainly help you with dietary changes.

You may also need to take antibiotics- traditionally Rifaximin and Neomycin have been recommended but this must be prescribed by a GP.
In a study published by Chedid et al, Herbal therapies are at least as effective as Rifaximin for resolution of SIBO.
Herbals remedies also appear to be as effective as triple antibiotic therapy for SIBO who did not respond to Rifaximin.


How common is SIBO?
The prevalence of SIBO ranges from 30-85%.
The prevalence of SIBO in patients with coeliac disease non-responding to a gluten-free diet was as high as 50%. In liver cirrhosis, SIBO was diagnosed in more than 50% of cases In a small study on elderly people (70 to 94 years old) who had lactose malabsorption, SIBO was documented in 90%.
