“Studies suggest that up to 78% of individuals with IBS may have SIBO as an underlying cause of their symptoms. Addressing SIBO can resolve IBS in many cases.”

What is SIBO, how is it diagnosed and how is SIBO typically treated?

What is SIBO?

SIBO stands for Small Intestinal Bacterial Overgrowth. It is a condition characterized by an abnormal increase in the population of bacteria in the small intestine. Normally, the small intestine has a relatively low number of bacteria compared to the large intestine. However, in SIBO, bacteria from the large intestine migrate upwards and multiply in the small intestine, leading to digestive symptoms and inflammation.

How does SIBO cause IBS symptoms?

The bacteria in the small intestine can ferment carbohydrates and produce excessive amounts of gas, causing symptoms such as bloating, heartburn, abdominal pain, diarrhoea, constipation and flatulence. SIBO can also interfere with the absorption of nutrients, leading to malnutrition, deficiencies and low energy.

How do you test for SIBO?

A SIBO breath test is done to diagnose the condition. The most common method for testing is the lactulose breath test. During this test, a lactulose solution is ingested, after which breath samples are taken at regular intervals to measure the levels of hydrogen and methane gases. Increased levels of these gases indicate the presence of bacterial overgrowth in the small intestine. This test is done at home and the test kit is sent back to the lab for analysis via post.

How do you get rid of SIBO?

Addressing SIBO involves a combination of dietary changes and antibiotics or herbal antimicrobial supplements. Antibiotics like rifaximin and/or metronidazole are commonly prescribed to kill off the excess bacteria. Alternatively, antimicrobial herbal supplements such as oregano, berberine, allicin and neem are used.  Dietary changes, such as a low FODMAP or low carbohydrate diet are recommended to help manage symptoms whilst targeting the overgrowth. Correct diagnosis and treatment as well as addressing the underlying cause of SIBO is important to prevent a SIBO relapse.

'My stomach issues have completely gone'

I feel like I have a lot less inflammation in my stomach. Some of the supplements and food ideas Claire recommended to me also really helped boost my mood and I came to realise that the stomach and mind are very much in tune. Some of Claire’s recommendations were things I would’ve never have thought of nor been told by a doctor.

'I have gained insight into foods that can trigger my symptoms and have had a significant reduction in symptoms'

Since working with Claire I have gained insight into foods that can trigger my symptoms and have had a significant reduction in symptoms, which has led to improved confidence in day to day life, and has actually made me able to make progress my career in a way that wouldn’t previously have been possible due to the unpredictable nature of my symptoms.

Louise – York

'Since working together my constipation has been completely resolved and my bloating has reduced by at least 75%'

Claire helped to identify that I’m actually suffering with SIBO, which has allowed her to tailor my plan more effectively. Claire couldn’t have put me more at ease from our first consultation and is always super friendly, upbeat and more than happy to help with any request or question. I’m so pleased to have come across Claire and would highly recommend her services to anybody struggling with their gut or thyroid, among the many other areas that she has expertise.

Holly, York

'With Claire's help & support, the candida is so much better!'

 I had been suffering with candida for ten years before contacting Claire. I had also had bladder & womb cancer so wanted to reduce my chances of further cancers & to alleviate the candida symptoms. 
 I can now eat much more normally, go out for meals & even enjoy a glass of wine & some chocolate, without suffering a painful flare up of symptoms. Claire is so friendly, caring & easy to talk to, very knowledgeable too. I always look forward to meeting with her & have no hesitation in recommending her.

Heather – York

I feel fortunate to have found Claire and she has played a very important role in me moving forward with my health issues. I will be forever grateful.

How long will it take to see improvements in my symptoms?

It varies from person to person depending on the root cause of the symptoms and how long you’ve had IBS/digestive symptoms. Symptom reduction can usually be seen within a few weeks of changing your diet and taking the recommended supplements, however, lasting improvements can sometimes take 6-12 months or more. I will provide you with guidance on how to continue working on your gut health longer term after the sessions ends.

Are the costs of tests and supplements included in the package fee?

No, supplements and tests are additional costs to the package.

How much can I expect to spend on testing and supplements or antibiotics?

A SIBO breath test costs around £150 ($190) with my practitioner discount and a comprehensive private stool test costs around £320 ($410). These are not mandatory tests, but they can be very helpful in providing us with information on the specific imbalances that we need to target. Supplement programmes range between £100-150 ($130-190) per month. However, I am happy to accommodate lower budgets. Rifaximin (for hydrogen-SIBO) costs around £250 ($320) for 1 round of antibiotics. Rifaximin + Metronidazole (for methane-SIBO) costs around £300 ($390) for 1 round of both antibiotics. 

Will I have to eat a really restrictive diet?

I provide a dietary framework to follow and recommend avoiding specific trigger foods, however, I don’t believe in perfection or deprivation. I help clients find enjoyable alternatives to their favourite foods and always apply the 80:20 rule – follow the diet 80% and allow 20% wiggle room for eating out and treats!

Will I have to stay on this diet forever?

No, not necessarily. The low FODMAP/fermentation diet isn’t a “forever” diet and should only be used therapeutically for symptom reduction whilst addressing the root cause of your gut health troubles. I help clients identify trigger foods that may need to be avoided or reduced longer term but I am a strong advocate of eating a varied and enjoyable diet.

Can I still do this programme if I am going on holiday?

Yes, that’s no problem. I am happy to work around holidays and other commitments. You can still follow the recommendations on holiday or stagger the programme to accommodate time away from home. I provide guidance on how to eat out and enjoy food like a “normal” person”!

Will doing a SIBO protocol get rid of my IBS and food intolerances?

Potentially yes – if SIBO is the root cause of your symptoms and food reactions. If addressing SIBO does not resolve the majority of your symptoms, then I will discuss investigating other root causes which could include other infections or toxicity, leaky gut, nervous system dysregulation and autoimmunity.

Will I have a detox reaction, what does this mean?

When we kill bacteria, toxins can be released into the gut. For some individuals, this can result in a worsening of symptoms initially such as loose bowel movements, more bloating, headaches and flu-like symptoms. This should only be short term and I provide recommendations to reduce the likelihood of experiencing a detox reaction.

Do you recommend herbs or antibiotics to address SIBO?

I predominantly use herbal supplements to target SIBO and other gut imbalances. However, I also work with clients who want to take the recommended antibiotics for SIBO. Both antibiotics and antimicrobial herbs are effective. The antibiotics have to be prescribed by a gastroenterologist or private doctor and I have a referral network for obtaining the antibiotics.  

Does the package include email support?

The package includes reasonable email support between sessions for example two emails per week with quick-fire questions about the diet, supplements and recommendations. New symptoms, test recommendations and further research need to be discussed at the next follow-up.

Do you accept health insurance?

Nutritional therapy is not covered by private health insurance as it is a complimentary therapy. Therefore, I am unable to accept health insurance.

What is your refund policy?

You can view the refund policy within the Practitioner-Client Terms of Engagement here.
