Gut Health Assessment in Brisbane

In short

A gut health assessment is a detailed consultation focused on finding the cause of digestive symptoms rather than treating them in isolation. Dr Goutham reviews your symptoms, history, diet, medications and lifestyle, then builds a personalised investigation plan — which may include blood tests, breath tests, stool and faecal calprotectin testing, gut microbiome testing, colonoscopy, gastroscopy or capsule endoscopy. It is ideal for ongoing or unexplained symptoms, and for anyone told they “just have IBS” who wants a clearer answer. Importantly, symptoms should never be assumed to be IBS until red-flag causes have been excluded.

Personalised gut health consultation with a specialist
What’s involved

A thorough, personalised consultation

A gut health assessment begins with a detailed consultation. Dr Goutham takes a careful history of your symptoms, medical background, diet, medications and the lifestyle factors that may be contributing to your gastrointestinal issues.

From there, a personalised investigation plan is developed to determine the cause of your symptoms and guide the right treatment. This may involve targeted diagnostic testing and, where appropriate, advanced imaging or specialised investigations to assess both the structure and the function of your digestive tract.

The goal is a holistic, evidence-based approach — investigations and treatments tailored to you, rather than a one-size-fits-all plan — supporting effective, long-term management of your gut health and overall wellbeing.

Symptoms we assess

Digestive symptoms worth investigating

A gut health assessment is particularly helpful for persistent or unexplained symptoms, including:

  • Bloating and excessive wind
  • Abdominal pain or discomfort
  • Altered bowel habits — diarrhoea, constipation, or alternating between the two
  • Reflux, heartburn or indigestion
  • Food intolerance or sensitivity
  • Nausea or early fullness after eating
  • Unexplained weight change or fatigue
  • Symptoms suggestive of a functional gastrointestinal disorder, such as IBS

If you have already been told your symptoms are “just IBS” but you do not have a clear answer, an assessment can help confirm the diagnosis or uncover a treatable cause that has been missed. You can read more in our article It’s Not Always IBS.

Diet, food intolerance and gut health testing
Tests we may use

Matching the right test to your symptoms

Not everyone needs every test. Your plan is built around your symptoms and history. Depending on the picture, investigations may include:

InvestigationWhat it looks at
Blood testsIron levels, inflammation, coeliac screening, thyroid and liver function
Faecal calprotectinHelps distinguish inflammatory bowel disease from functional gut disorders
Stool & microbiome testingThe balance of bacteria in the gut, to guide dietary and lifestyle strategies
Breath testingLactose or fructose intolerance and small-bowel bacterial overgrowth
GastroscopyDirect view of the oesophagus, stomach and duodenum (and coeliac biopsies)
ColonoscopyDirect view of the large bowel to exclude structural causes
Capsule endoscopyExamines the small bowel when standard scopes are normal

Conditions we find

What a gut health assessment can uncover

Many digestive symptoms can arise from a range of conditions. A structured assessment helps tell them apart so the right treatment can begin. These include:

  • Irritable bowel syndrome and other functional gastrointestinal disorders
  • Coeliac disease and food intolerances
  • Inflammatory bowel disease (Crohn’s disease and ulcerative colitis)
  • Reflux and gastritis
  • Gut microbiome imbalance
  • Enzyme deficiencies and malabsorption
  • Structural causes such as polyps or, rarely, bowel cancer

If a colonoscopy or other test is normal but symptoms continue, further functional testing — such as microbiome analysis or dietary assessment — can help explain what is going on and what to do next.

When to seek care sooner

Symptoms that need prompt assessment

Most digestive symptoms are not dangerous, but some warrant earlier investigation. Speak with your GP or our team promptly if you notice:

  • Blood in the stool or rectal bleeding
  • Unexplained weight loss
  • Unexplained iron deficiency or anaemia
  • A persistent change in bowel habit, especially if you are aged 45 or older
  • Difficulty swallowing, or persistent vomiting
  • A family history of bowel cancer, coeliac disease or inflammatory bowel disease

Two important safety points

Symptoms should never be assumed to be IBS until these red-flag causes have been excluded. And if coeliac disease is being considered, keep eating gluten until your blood tests and any biopsies are complete — stopping gluten early can hide the diagnosis.

Common patient questions

Gut Health FAQs

What is a gut health assessment?
It is a thorough consultation focused on finding the underlying cause of digestive symptoms. Dr Goutham reviews your symptoms, history, diet and lifestyle, then builds a personalised plan of investigations and treatment rather than treating symptoms in isolation.
Do I need a referral?
A GP referral is recommended and allows you to claim a Medicare rebate for the consultation, but you are welcome to enquire directly and our team will guide you. We work closely with your GP throughout.
Will I definitely need a colonoscopy or gastroscopy?
Not necessarily. Some people need a procedure to exclude structural causes; others are managed with blood, stool, breath or microbiome testing and dietary changes. Your plan is matched to your symptoms.
I’ve been told I have IBS — is an assessment still worthwhile?
Yes. IBS is a real diagnosis, but it should only be made once red-flag causes have been excluded. An assessment can confirm IBS, optimise its management, or uncover a treatable cause that has been missed.
What is gut microbiome testing?
It is specialised stool testing that analyses the balance of bacteria in your digestive system. The results can guide personalised dietary and lifestyle strategies, and are most useful as part of a broader assessment rather than on their own.
Should I change my diet before the assessment?
Generally, keep eating as you normally do so your symptoms can be assessed accurately. In particular, if coeliac disease is a possibility, keep eating gluten until testing is complete, as stopping early can hide the diagnosis.
