What is SIBO?
SIBO (Small Intestine Bacterial Overgrowth) is a condition in the small intestine where good or bad bacteria begin to congregate in far higher numbers than normal. The bacteria cause a wide variety of uncomfortable and often embarrassing symptoms for millions of SIBO sufferers. Symptoms of SIBO can affect much more than just digestion so sadly it is often missed as a possible cause of some health problems. The only way to currently diagnose this condition is by taking a SIBO breath test – a simple to use, DIY home test kit.

Signs of SIBO
SIBO affects people in many different ways – Digestion is most commonly affected with bloating, constipation and or diarrhoea being typical but it is a complicated condition and it can cause a very broad array of symptoms. Often missed as a contributory factor SIBO can play a part in Chronic Fatigue (CFS), roseacea, restless legs, cystitis, prostate issues and many more health concerns.
Symptoms of SIBO
- Diarrhoea – Usually associated with hydrogen dominant SIBO
- Constipation – usually associated with methane dominant SIBO
- Alternating constipation and diarrhoea
- Severe Bloating
- Abdominal pain and cramps
- Leaky gut – Intestinal permeability
- Malabsorption which can lead to Steatorrhea (Fatty Stool) or anaemia
- Chronic pancreatitis
- Lactose intolerance
- Fructose intolerance
- Sucrose intolerance
- Iron and B12 deficiency
- Acid Reflux
- Gerd (Gastro oesophageal reflux disease)
- Acne rosacea
- Skin rashes
- Restless legs
- Joint pain
- Weight loss or gain
- Food sensitivities
- Interestitial cystitis
- Rheumatoid arthritis
- Chronic Fatigue sydrome
What causes SIBO?
Research shows the main cause of SIBO is a reduction or slowing of motility (the movement of food) through the gut, this impacts on the levels of bacteria present in the small intestines. Think of a stagnant pond where bacteria flourish and grow in large unwanted amounts opposed to a clean free flowing stream which keeps bacteria levels as they should be.
There are two main causes of slowed motility in the gut.
1. The cleansing sweeping action ‘Migrating Motor Complex’ MMC in the gut stops working properly. The MMC makes cleansing sweeping like motions between meals that ‘clean’ the small intestine. The sweeping motion should move undigested food and excess bacteria towards the large intestines. When the MMC is faulty undigested food becomes food for the bacteria causing or exacerbating SIBO. The major cause of malfunctioning MMC is food poisioning.
2. Structural changes which affect the motility of the gut can also cause SIBO. Some diseases, medical conditions and procedures can cause these structural changes. For example; scarring after operations, Inflammatory bowel disease, diverticulosis, blind loops, radiation damage, stricture, fistulas, intestinal pseudoobstruction and adhesions resulting from surgery are all known to impact on or cause SIBO.
Contributory and risk factors that can affect SIBO
- Low stomach acid – hypochlorhydria
- Drug-induced hypoacidity (Low stomach acid) – This is commonly seen on those that take PPI’s Proton pump inhibitors PPI’s
- Inflammatory bowel disease
- Chronic alcohol use
- Celiac disease
- Chronic pancreatic insufficiency
- Lactose intolerance – lactose is the type of natural sugar that you find in dairy products – this is not the same as lactulose which is used for the SIBO breath test
- Damaged ileocecal valve
- Immunodeficiency (especially of secretory immunoglobulin A)
How to treat SIBO
World leaders in the battle against SIBO have been treating and researching SIBO for many years now and have found there are 3 main ways to address SIBO:
The antibiotic Rifaxamin is considered the number 1 antibiotic choice for hydrogen or Methane dominant SIBO and is often combined with neomycin or metronidazole.
Rifaxamin isn’t licensed for use against SIBO in the UK however some people do manage to get a prescription from either their GP or gastrointestinal consultant. The IBS and SIBO clinic practitioners work closely with a private GP who is happy to prescribe Rifaxamin when suitable.
A range of different natural plant based antimicrobials have been found to be as effective against SIBO as the antibiotics and these can also impact on SIFO (small intestine fungal overgrowth).
As the choice of antimicrobial is very dependant on the type of SIBO you have; hydrogen, methane or hydrogen sulphide, we recommend working with a knowledgable SIBO practitioner to ensure your programme is effective.
3. Elemental Diet
The elemental diet involves consuming a predigested drink that provides all of your daily nutrient needs but doesn’t feed the bacteria.
Studies show the elemental diet helps to eradicate SIBO in 85% of people.
Many people shy away from this as they worry about weight loss and energy but if it is done correctly, with a practitioner if possible, this shouldn’t be an issue and shoudn’t be ruled out as it can be a very successful SIBO treatment.
There are also a number of different diets that can be used to help manage the symptoms of SIBO.
Diet alone will not eradicate SIBO. Dietary changes can however support an antimicrobial programme and can help to make you more comfortable by relieving some symptoms.
The most common diets that are followed are the SIBO specific diet, The FODMAP diet, SCD, Bi-Phasic diet and the Cedar’s Sinai Diet. The suitability of one diet for one person and another for someone else be very confusing.
The individual suitablity of one diet over another is thought to be due to the type of bacteria causing the overgrowth.

Order a SIBO breath test
There are two types of SIBO breath tests available.
The Lactulose breath test and the Glucose breath test.
We tend to favour the Lactulose breath test as do most world SIBO experts. Lactulose is a non absorbable sugar and is often confused for lactose the type of sugar you find in dairy produce – this makes lactulose dairy free. Lactulose passes through the whole of the small intestines enabling it to pick up SIBO in the early and latter parts of the small intestines.
The Glucose breath test is slightly more accurate but glucose is absorbed higher up in the early part of the small intestines and therefore can miss SIBO if the overgrowth is further along the small intestines.

The Smart SIBO test takes 3 hours to complete but you wil need to follow a prep diet for 1 day before or, if constipated 2 days before the test.
I am doing both tests – Can I do the Lactulose and the Glucose breath test at the same time?
To ensure accuracy of the test results the tests need to be done on separate days. Please follow the prep diet and fast as instructed and complete test no 1. Please then continue with the prep diet and fast over night and collect the breath samples for test 2.
Will you explain what my results mean?
Yes, We send an email with your results and we explain what your results mean – Whether they are hydrogen or methane positive or negative or if your results are looking like a possible hydrogen sulphide type of SIBO. We include a supporting document which explains how the test is interpreted which you can share with your health care provider if you wish.

No this won’t be a problem. Lactulose (not lactose) is consumed at the start of the test and is a mixture of galactose and fructose.
Do I need to follow any special dietary requirements for the test?
Yes, You will need to follow a special low fermentation diet for 1 day before the test or if constipated for 2 days. The Instructions include full details about the diet including meal ideas.
I am on a FODMAP diet and want to do the test – will it affect my results?
Being on the FODMAP diet will not affect your results unless you have been on the diet for more than 10 months.
