SIBO Nutrition Therapy
Expert guided SIBO nutrition therapy that identifies the real drivers of your symptoms. Evidence based protocols that support gut regulation and improve long term digestive outcomes.
SIBO Trigger Identification
Systematic identification of SIBO triggers including food patterns, stress responses and gut sensitivity. A structured approach that clarifies what your gut can tolerate and expands your diet over time.
Chronic SIBO Patterns
Support for long standing SIBO with persistent bloating, pain and bowel irregularity. Personalised nutrition therapy that restores digestive rhythm and improves daily quality of life.
SIBO Symptom Mapping
Comprehensive assessment to map your SIBO symptoms and uncover the patterns driving flare cycles. Targeted nutrition therapy that builds stability and supports long term digestive regulation.
The gut microbiome influences immune function, mental health, hormonal regulation, weight management, skin health and energy, yet SIBO often leaves people managing symptoms for years rather than resolving the underlying cause.
Jake’s clinical approach starts with a thorough intake including current symptoms, health history, recent investigations, diet and lifestyle and builds a plan specific to your SIBO, not a generic protocol pulled from the internet.
Whether you are newly diagnosed with SIBO, have tried everything or simply know something is off but have not been given answers, this is the level of SIBO care that actually moves the needle.

Chronic bloating
Daily bloating that does not resolve with dietary changes signals ongoing bacterial overgrowth.
Abdominal pain
Recurrent pain or cramping that disrupts meals, sleep or daily function indicates active SIBO patterns.
Constipation cycles
Slow, incomplete or infrequent bowel movements that cycle unpredictably reflect methane‑dominant SIBO.
Explosive diarrhoea
Sudden, urgent or watery stools point to hydrogen‑dominant SIBO and impaired gut motility.
Post‑meal discomfort
Pain within minutes of eating suggests fermentation occurring in the small intestine.
Food intolerance expansion
A growing list of foods causing symptoms indicates worsening dysbiosis and reduced digestive resilience.
Unpredictable flare cycles
Symptoms that spike without clear triggers show unstable gut regulation driven by SIBO.
Self-management failure
When supplements, diet changes or online protocols fail, it reflects deeper SIBO mechanisms needing clinical intervention.

No, you do not need a formal gut health diagnosis to book. Many clients come in with bloating, abdominal discomfort, irregular bowel habits or unresolved digestive symptoms without a clear label.
Jake will conduct a thorough intake, review any existing investigations and may recommend further testing where appropriate. A diagnosis helps, but it is not required to get started.
A gastroenterologist manages the medical and diagnostic aspects of SIBO, while Jake builds a personalised nutrition strategy that restores gut function, reduces inflammation and stabilises daily SIBO symptoms.
They work differently, and many clients choose to work with both for the most complete care.
No, you will not be placed on a highly restricted diet. Jake’s approach is structured, personalised and clinically guided, but it is designed to be sustainable and flexible.
The goal is to support gut function, calm inflammation and stabilise SIBO symptoms while keeping your diet as broad and enjoyable as possible.
Most clients actually gain more dietary freedom over time, not less.
Most clients begin noticing meaningful changes within the first few weeks.
Improvements often include better energy, more stable SIBO digestion, reduced bloating and clearer structure around what their gut needs.
Gut healing itself evolves over time, but the behaviours that drive better motility, reduced inflammation and SIBO symptom relief begin shifting almost immediately.
Jake monitors your progress closely and adjusts your plan so you continue moving forward with confidence.
Yes, Jake can work alongside your GP or gastroenterologist. A GP provides broad medical oversight and a gastroenterologist manages the diagnostic and medical aspects of SIBO, while Jake focuses on the nutritional, behavioural and functional drivers behind your symptoms.
Many clients work with both, especially when there are ongoing investigations, complex SIBO symptoms or no explanation for why their gut has become unstable.
Jake combines world class expertise as a SIBO nutritionist with extensive experience supporting both younger clients with emerging SIBO symptoms and adults already managing chronic SIBO patterns. His approach gives clients a clear clinical advantage built on precision, science and measurable results.
