Functional Medicine for SIBO with Mosaic Medical in the UK
Relief from SIBO Starts with Root-Cause Medicine
What Is SIBO?
Small Intestinal Bacterial Overgrowth (SIBO) occurs when bacteria that normally live in the large intestine (colon) begin to overpopulate the small intestine. This imbalance can trigger a wide range of digestive and systemic symptoms.
- Bloating after meals
- Excessive gas and belching
- Abdominal pain or cramping
- Diarrhoea, constipation, or alternating patterns
- Food intolerances
- Non-digestive symptoms (such as fatigue, brain fog, or skin issues)
SIBO is often misdiagnosed as Irritable Bowel Syndrome (IBS). Conventional treatment usually relies on antibiotics, which can bring short-term relief. However, unless the root cause is addressed, symptoms frequently return.
Our Functional Medicine Approach to SIBO
At Mosaic Medical, we go beyond symptom suppression to uncover and treat the underlying drivers of SIBO.
- Comprehensive stool and breath testing – including lactulose breath tests to identify methane, hydrogen, or hydrogen sulphide dominance
- Nutritional support and targeted antimicrobials – these may be herbal or conventional antibiotics, tailored to your needs
- Gut repair strategies – using probiotics, enzymes, and anti-inflammatory support
- Stress and nervous system regulation – recognising the gut-brain connection in motility and resilience
- Personalised dietary plans – beyond restrictive approaches, designed to restore balance
Our aim is not just to clear bacterial overgrowth, but to restore healthy gut function and reduce the risk of recurrence.
What Makes Our SIBO Care Different
- Whole-person treatment – we focus on you, not just the overgrowth
- Advanced testing – lactulose breath testing, stool analysis, and nutritional assessments
- Personalised care plans – with ongoing support and adjustments
- Experience with chronic and relapsing cases – helping patients who have struggled with recurring SIBO
- Safe medical oversight – as GMC-registered doctors, we can prescribe when appropriate and also recommend supplements, nutrition, and lifestyle interventions
Root Causes of SIBO We Investigate
SIBO is rarely random – there are often clear (and sometimes hidden) contributing factors. These may include:
- Low stomach acid
- Gut motility issues (slow transit, vagus nerve dysfunction)
- Previous gut infections or food poisoning
- Medications that alter gut function
- Connective tissue conditions (e.g. hypermobility syndromes)
- Structural or inherited predispositions
By identifying your unique drivers, we can design strategies to treat SIBO effectively and prevent recurrence.
FAQ – SIBO & Functional Medicine
How do you test for SIBO?
We use at-home breath testing kits that measure hydrogen, methane, and sometimes hydrogen sulphide after you drink a sugar solution. This identifies both the type and severity of SIBO.
Can you help if I’ve already tried antibiotics or herbal protocols?
Yes. Many of our patients come to us after previous treatments haven’t worked long-term. We specialise in uncovering hidden triggers and guiding step-by-step gut repair.
Do you offer remote consultations?
Yes. We support patients virtually across the UK.
How do appointments work?
Your first appointment is 90 minutes, with your doctor reviewing your case in detail beforehand. During the consultation, we’ll identify likely causes, map out next steps, and decide on any testing.
Does the appointment price include testing?
Testing is personalised and separate from appointment fees. We only recommend tests that will meaningfully impact your care plan.
I already have a test and a diagnosis – can you still help?
Yes. You can upload your results in advance. If you have a large number of results, there may be a small preparation fee, but we’ll always discuss this with you first.
How does the nutrition side work?
We provide tailored nutrition advice as part of your care. For complex cases, we recommend working with our nutritional therapist alongside your doctor for quicker, more effective results.
