When Your Doctors Can't Find Answers: What's Next for Your Gut Health?
You have seen your GP. Perhaps you have spoken with a gastroenterologist, completed blood tests or had a colonoscopy. You have followed the advice, yet the bloating, constipation, diarrhoea, reflux or abdominal discomfort keeps returning.
Then comes a sentence many people find deeply frustrating: “Everything looks normal.”
But you still do not feel normal. So what happens when your medical team cannot find an answer to your health concerns? Who do you go to next?
At The Gut Guy, we believe the next step should begin with listening, careful clinical screening and a coordinated plan—not immediately buying another test or another cupboard full of supplements. Conventional medical care remains essential, particularly when symptoms are new, severe or worsening. Our role is to help identify sensible next questions and, when appropriate, complement that care.
Your GP should always be your first point of contact for a non-emergency health concern. Please keep your GP and any specialists informed about your symptoms, test results, dietary changes and supplements, even if you decide to explore natural healthcare. If symptoms are severe or you suspect an emergency, seek urgent medical attention rather than waiting for an appointment.
Your GP's role—and what The Gut Guy cannot do
Your general practitioner (GP) is a medically trained doctor who assesses your symptoms and medical history, performs examinations, investigates possible causes, makes medical diagnoses, prescribes medicines and coordinates treatment. GPs can request appropriate pathology and imaging, consider which tests may attract Medicare rebates, and refer you to gastroenterologists or other specialists. They also help manage chronic conditions, assess medication risks and recognise when you need urgent care. Your GP often has the most complete picture of your health over time. This is why healthdirect recommends a GP as the usual first contact for health concerns.
If initial investigations have not explained your symptoms, that does not mean your GP's job is finished. It may be worth reviewing what has already been excluded, whether symptoms have changed, whether a follow-up or specialist referral is needed and whether a second medical opinion would help. For people with ongoing symptoms, our gut-health service is intended to complement this medical pathway, not compete with it.
What we can do: Our qualified naturopaths and clinical nutritionists can take a detailed digestive-health history, review results you provide, assess whether natural health support is appropriate, discuss dietary strategies and—when suitable—recommend targeted supplements within their professional scope. Our naturopathy service and clinical nutrition service focus on practical, individualised support alongside your medical care.
What we cannot do: We are not a GP clinic. Our naturopaths, nutritionists and health coaches do not replace a medical examination, make formal medical diagnoses, prescribe prescription-only medicines, provide Medicare-rebated GP investigations, perform endoscopy or colonoscopy, or manage medical emergencies. A microbiome report cannot rule out serious disease. When a symptom or result suggests a medical concern, we encourage review by your GP or appropriate specialist rather than relying on a supplement or functional test.
How shared care should work: Tell your GP about every supplement and natural health product you use, because products can interact with medicines or be unsuitable for certain conditions. Keep your specialists updated too. Our clinicians can help you prepare questions and relevant information to take back to your doctor. You remain free to seek another medical opinion if important questions are unanswered.
The gap between “normal results” and feeling well
A normal investigation is genuinely useful: it can make certain medical conditions less likely. However, no single test evaluates every possible cause of digestive symptoms. Depending on your presentation, a GP may need to revisit conditions such as coeliac disease, inflammatory bowel disease, infections, medication effects or other digestive disorders. Conditions including irritable bowel syndrome (IBS) may be diagnosed from a pattern of symptoms and appropriate assessment, even when routine investigations are unremarkable.
The problem we see in the gut health industry is what happens next. People can be pushed toward expensive testing before anyone has reviewed their medical history, or placed on restrictive diets without a clear reason. Others are told to simply live with symptoms that continue to affect their daily lives.
We think you deserve a more considered starting point.
Our first step: a clinician-led Clinical Screening Call
Our clinical screening pathway begins with a consultation conducted by a qualified practitioner from our naturopathy or clinical nutrition team. Before recommending microbiome mapping or SIBO testing, the clinician considers your symptoms, previous investigations, goals, safety and likely next steps.
During this call, the clinician can:
• Screen your suitability for natural healthcare. Understand your medical history, medicines, age, symptoms and whether our service is appropriate or a medical review should come first.
• Review your previous results and treatments. Look at relevant blood tests, stool tests, specialist letters, diets and supplements, rather than starting from scratch.
• Consider one or two targeted supplements, if appropriate. A qualified practitioner may suggest or prescribe carefully selected products based on your presentation and medication safety. Some people will not need any supplements at this stage. Product costs, if any, are separate.
• Check for red flags. Symptoms such as gastrointestinal bleeding, unexplained weight loss, persistent vomiting, iron-deficiency anaemia, difficulty swallowing, fever or severe progressive pain may require timely medical evaluation instead of a functional testing pathway.
• Help you prepare better questions for your doctor. These might include which medical causes have been excluded, whether coeliac screening or inflammation tests are relevant, and whether further specialist assessment is indicated.
• Discuss a referral to a trusted medical professional. If medical investigation is warranted, we can help you understand why seeking advice from your GP or an appropriately qualified specialist matters.
• Identify foods worth temporarily reducing. Advice is based on your symptoms and nutritional needs, not an automatic instruction to eliminate gluten, dairy or entire food groups.
• Identify foods to include. We consider balanced meals, tolerable sources of fibre, variety and nutritional adequacy, with adjustments where symptoms make particular foods difficult.
• Recommend a sensible testing pathway—or explain why testing is unnecessary. Sometimes the next step is a GP investigation. Sometimes a gut microbiome test or SIBO assessment may be worth discussing. Sometimes it is better to begin with a practical diet and symptom-management plan.
The purpose is not to promise a diagnosis in one appointment. It is to establish a safer, more focused direction.
Who might support your screening and treatment?
The clinical team includes practitioners such as Emma Hickey, Linda Spirou and clinical nutritionist Sarah Wade. Your practitioner leads the clinical decisions; I help with practical implementation during the second call. That separation of roles is important for your safety and clarity.
Two consultations for $164: clinical screening plus a practical follow-up with Josh
We know that receiving advice is one thing; understanding how to put it into everyday life is another. That is why the $164 fee includes two separate conversations:
Consultation 1 — Clinical Screening Call with a qualified practitioner. Your clinician reviews your presentation, screens for concerns, discusses preliminary recommendations and decides whether further medical or gut-health investigations may be appropriate.
Consultation 2 — Post-Screening Call with me, Josh Williams. I will walk you through the initial plan in plain English and help you organise the practical next steps. I am a gut-health educator and health coach, not the treating clinician; any medical interpretation, prescribing or clinical changes remain with your practitioner.
Infographic: Two consultations for $164, separating clinical advice from practical follow-up support.
In our post-screening conversation, we can:
• Go through your initial care plan so you know what each step involves.
• Work through implementation, routines, timing and common practical challenges.
• Address further questions and take clinical questions back to the practitioner where needed.
• Discuss sensible practical adjustments that fit your life, while leaving clinical treatment changes to your practitioner.
• Share my screen and show you an example of the type of gut test your clinician has recommended, explaining what the report format looks like—not interpreting your personal results.
• Decide together whether you want to proceed with the recommended gut testing, with a clear understanding of what it may and may not tell you.
The total is $164 for both consultations. Gut tests, supplements, subsequent treatment consultations and any external medical investigations are not included and are only considered separately if appropriate. You are not required to purchase a test.
What is functional testing—and which tests actually answer your question?
“Functional testing” is a broad marketing term. It can describe very different tests, with very different levels of evidence and clinical usefulness. The important question is not how many markers a report contains. It is whether a result would meaningfully influence a qualified practitioner's advice or your medical care.
1. Conventional medical investigations: often the first priority
Depending on symptoms, your doctor may consider coeliac serology, full blood count and iron studies, inflammation markers, faecal calprotectin, stool infection testing, imaging or endoscopy. These investigations answer questions that microbiome mapping cannot answer and may be Medicare-funded when clinically indicated. We encourage patients to maintain an ongoing relationship with their GP.
2. Gut microbiome mapping: a detailed microbial profile
A modern gut microbiome test uses a stool sample to describe microbial DNA and aspects of the organisms living in your gut. Shotgun metagenomic testing can examine microbial composition, diversity and potential microbial functions. It may provide useful context for practitioner-led discussions about diet and gut-health strategies, but it cannot establish the cause of symptoms by itself. The clinical value of individual microbiome findings is still developing; testing must be interpreted cautiously alongside the broader presentation.
3. SIBO breath testing: a different question entirely
Small intestinal bacterial overgrowth (SIBO) is not the same thing as an altered stool microbiome profile. Breath testing looks at changes in hydrogen and, where available, methane after consuming a test substrate. The results have limitations and must be considered alongside symptoms and clinical guidance. A Microba stool microbiome test does not diagnose SIBO. Where appropriate, SIBO breath testing is considered as a separate investigation.
4. Other tests marketed as “functional”
You may also encounter food intolerance panels, hormone and cortisol profiles, organic acid tests, elaborate stool panels and tests claiming to identify every nutrient or toxin issue. The reliability and clinical utility of these products vary considerably. Some can lead to unnecessary spending or avoidable dietary restrictions if used without a clear clinical question. Our team does not routinely offer these as part of our gut-testing pathway.
The Gut Guy focuses on two gut-testing pathways
We deliberately keep our own gut-health testing offering focused: gut microbiome mapping and SIBO breath testing. That does not mean every patient needs either test. Our clinicians first consider whether standard medical investigations, symptom management or nutritional care would be a better step.
Infographic: Different investigations answer different questions. A Microba microbiome map cannot diagnose SIBO.
For gut microbiome mapping, the only company we use is [Microba](https://www.microba.com/practitioners/products). We select Microba for its metagenomic approach and its capacity to describe microbial composition and potential functions. We do not represent Microba stool mapping as a medical diagnostic tool, and we do not use it to diagnose SIBO.
For SIBO, an appropriate breath-testing pathway is considered separately when a clinician believes it is relevant. SIBO testing is not performed by Microba's stool microbiome mapping service.
If an alternative investigation or specialist opinion makes more sense, we will discuss that rather than automatically recommending a test we sell.
What happens after screening?
After the clinical call, I meet with you for the second consultation included in the $164 fee. We make sure the recommendations are understandable and realistically achievable. If testing has been proposed, you can see an example report, ask about the process and costs, and make an informed choice before committing.
If you do proceed, your treating clinician remains responsible for reviewing the findings and deciding what, if anything, they mean for your care. Depending on your needs, our team can provide naturopathic consultations, clinical nutrition support and ongoing implementation coaching, with medical collaboration where needed.
Our goal is not to sell you every available investigation. It is to help you find the next reasonable step.
Frequently asked questions
What if my GP says my blood tests are normal?
Normal results are useful information, but they are not the end of a thorough history and symptom review. A clinician can help you prepare questions for your GP, consider whether appropriate medical evaluation has been completed, and explore practical dietary or gut-health support.
Will the $164 Clinical Screening Call package include a microbiome test?
No. The $164 covers two consultations: the qualified clinician's screening call and the subsequent practical follow-up with Josh. Tests, supplements and any further treatment are charged separately, if recommended and accepted.
Can you diagnose SIBO from my Microba results?
No. Stool microbiome mapping does not diagnose SIBO. Breath testing is a separate investigation that may be considered if your symptoms and clinical assessment warrant it.
Do I need to stop seeing my doctor?
Absolutely not. We encourage ongoing medical care and can help you prepare questions for your doctor or discuss when a referral is appropriate. Natural healthcare should complement, not replace, medical assessment.
Do you offer consultations if I live outside Melbourne?
Yes. The Gut Guy is Melbourne-based and offers telehealth support across Australia where clinically appropriate. Learn more about our team and how we work.

A note on safety and evidence
Your GP should always be your first step for any non-emergency health concern, and your medical team should remain informed and involved throughout your care. The Gut Guy's naturopathic, nutrition and coaching services complement medical care; they do not replace your GP, medical diagnosis, prescription treatment, specialist assessment or emergency care. This article provides general education only and is not a diagnosis or personalised medical advice. Seek urgent medical assistance for severe abdominal pain, significant bleeding, fainting or other acute symptoms. If you have persistent symptoms, unexplained weight loss, iron-deficiency anaemia, progressive swallowing difficulties or other warning signs, contact your GP promptly. Tell your GP and specialists about any supplements, restrictive diets and test results. Supplement and dietary advice should be individualised by a qualified practitioner and checked against medicines, health conditions and nutritional needs. Microbiome mapping and breath testing have limitations and cannot replace conventional medical investigations.
