Gut Health Checks in Singapore

Gut health has become a crowded market, and it is now easy to buy a test before anyone has asked what your symptoms are. A gut check at Bethesda Medical starts the other way round — with an assessment, so that whatever comes next is answering the right question.

Some gut symptoms need a doctor, not a test kit

This is the most important thing on the page, so it comes before everything else.

See a doctor promptly if you have any of these

Blood in your stool, or black tarry stools. Unexplained weight loss. A persistent change in bowel habit lasting more than a few weeks. Persistent abdominal pain, or a lump in the abdomen. Difficulty swallowing, or vomiting blood. HealthHub's guidance is explicit: if symptoms like blood in the stool or a change in bowel habit appear, see a doctor promptly — even if a previous screening test came back normal.

The reason this matters here is uncomfortable but simple. Bloating, constipation and irregular bowel movements are exactly the symptoms marketed as reasons to buy a gut microbiome test — and they are also the symptoms of colorectal cancer, inflammatory bowel disease and coeliac disease. Colorectal cancer is the most common cancer in Singapore. A stool sample sent off for bacterial sequencing does not look for any of that, and the weeks spent waiting for the report are weeks not spent finding out.

What we do

What a gut health check involves here

An assessment first, then the tests that your symptoms actually call for.

Most digestive problems are worked out by taking a careful history: what the symptoms are, how long they have been there, what makes them better or worse, what you eat, what medicines you take, and whether anything in your family history changes the picture. That conversation decides everything that follows.

From there we arrange what is indicated — blood tests for anaemia, inflammation, thyroid or coeliac disease; stool tests for blood or infection; and colorectal cancer screening where you are due for it. Some people need nothing more than reassurance and a change to how they eat. Some need a specialist, and we will say so.

Irritable bowel syndrome is common, and it is a real diagnosis rather than a shrug — but it is one made after the serious causes have been considered, not instead of considering them.

  • A proper symptom assessment, with red flags checked
  • Blood tests where indicated — anaemia, inflammation, coeliac screening, thyroid
  • FIT for colorectal cancer screening, subsidised under Healthier SG for eligible patients
  • Stool tests for infection where the history suggests it
  • Medication review — a surprising number of gut symptoms are side effects
  • Referral for colonoscopy or a gastroenterologist when that is the right step
Screening

The stool test with the strongest evidence

If you want one gut check that is proven to save lives, this is it.

FIT looks for hidden bloodThe faecal immunochemical test detects traces of blood in the stool that are invisible to the eye and can be an early sign of polyps or colorectal cancer.
Two samples, once a yearTwo stool samples are collected over two days for accuracy, and screening is repeated annually.
A positive result is not a diagnosisIt means blood was found and the cause needs identifying — often something harmless like haemorrhoids. The usual next step is a colonoscopy, which we arrange.

FIT is part of national screening under Healthier SG and is subsidised for eligible patients. It is for people without symptoms — if you already have symptoms, screening guidance does not apply to you and you need assessing instead.

Microbiome testing

Gut microbiome checks: what they can and cannot tell you

The science is real and moving quickly. The marketing has moved faster.

What it can do

  • Describe which bacteria are present in your stool sample and in what proportions
  • Report a diversity score and compare you against a reference population
  • Give a structured starting point for diet and probiotic choices, instead of trial and error
  • Make abstract advice concrete, which for some people is what finally changes behaviour

What it cannot do

  • Diagnose anything. There is no microbiome pattern that identifies IBS, IBD, coeliac disease or bowel cancer
  • Screen for cancer. It does not look for blood, and it is not a substitute for FIT or colonoscopy
  • Explain your symptoms. A low diversity score is not a cause; it is an observation
  • Stay still. Your microbiome shifts with diet, illness and antibiotics, so a result is a snapshot
  • Replace an assessment — which is the main way it goes wrong

Used well, a microbiome profile suits someone whose symptoms have already been assessed, whose serious causes have been excluded, and who wants a more structured approach to diet than guesswork. Used as a first step for undiagnosed symptoms — which is how it is most often sold — it answers a question nobody asked. If it is right for you, we will arrange it here and go through the report with you, because a list of bacterial names is very hard to act on alone.

Everyday

What actually helps your gut

Unglamorous, and better evidenced than most things sold for gut health.

Range, not superfoods

A wider variety of plants across the week does more than any single ingredient.

Enough fibre

Most people fall short. Increase it gradually, or you will feel worse before better.

Sleep and stress

The gut responds to both, which is why symptoms flare in difficult periods.

Movement

Regular activity supports bowel regularity and the microbiome alike.

FAQ

Gut health checks — frequently asked questions

What is a gut health check?
It depends what you mean, and the difference matters. A clinical gut check is an assessment of your digestive symptoms by a doctor, with the tests indicated by what you describe — blood tests, stool tests for blood or infection, coeliac screening, and referral for a colonoscopy where that is appropriate. A gut microbiome test is something different: a stool sample analysed for the bacteria living in your bowel. It is interesting, and increasingly useful, but it is not how bowel disease is diagnosed.
I have bloating and a change in bowel habit. Should I do a gut microbiome test?
Not first. Those symptoms need assessing properly, because they overlap with conditions that must not be missed — colorectal cancer, inflammatory bowel disease and coeliac disease among them. HealthHub advises that anyone who develops symptoms such as blood in the stool or a change in bowel habit should see a doctor promptly, even if a previous screening test was normal. Come and be assessed. If a microbiome profile is useful afterwards, it will still be there.
What is the FIT test, and how is it different?
The faecal immunochemical test looks for tiny amounts of blood in the stool that you cannot see, which can be an early sign of polyps or colorectal cancer. It is a screening test with real evidence behind it and is offered nationally, with two samples collected over two days and repeated annually. A microbiome test does not look for blood and does not screen for cancer. The two answer entirely different questions.
Is the FIT test subsidised?
Yes. Colorectal cancer screening with FIT is part of Healthier SG Screening, and eligible Singapore Citizens pay a small subsidised amount per screening visit at participating CHAS clinics. Ask us what applies to you — we can arrange it at your consultation.
Does a positive FIT mean I have cancer?
No, and this is worth knowing before you test. A positive result means blood was detected, which often has a harmless explanation such as haemorrhoids. It does mean the cause needs identifying, and the usual next step is a colonoscopy. We will explain the result and arrange the referral.
What does a gut microbiome test actually measure?
It sequences the bacteria in a stool sample and reports what is present and in what proportions — typically a diversity score, comparisons against a reference population, and suggestions for diet or probiotics. Some providers also report a "microbiome age" or functional scores. It describes the community of organisms in your bowel at the moment you collected the sample.
Can a microbiome test diagnose a condition?
No. There is no microbiome pattern that diagnoses irritable bowel syndrome, inflammatory bowel disease, coeliac disease or bowel cancer. The science is genuinely advancing and the associations are real, but a microbiome profile is not a diagnostic test and should not be treated as one. If you have symptoms, the diagnosis comes from assessment and validated tests.
So is a gut microbiome test worth doing at all?
It can be, for the right person and the right question — usually someone whose symptoms have already been assessed, whose serious causes have been excluded, and who wants a more structured approach to diet and probiotics than trial and error. It is far less useful as a first step for undiagnosed symptoms, which is the way it is most often used.
Does the sample need to be collected at the clinic?
No, these are stool samples collected at home, which is one reason they appeal. Our role is deciding whether the test answers your question, making sure nothing more urgent is being missed, and interpreting the result with you afterwards — a report full of bacterial names is difficult to act on alone.
Can probiotics fix my gut?
Sometimes they help, and for particular strains and particular problems there is reasonable evidence. But probiotics are not a substitute for finding out what is wrong, and "gut health" supplements are marketed far more confidently than the evidence supports. If your symptoms have a cause, treating the cause works better.
What can I do myself for gut health?
More than any test will do for you. Eat a wider range of plants rather than chasing one superfood; get enough fibre; keep alcohol moderate; do not smoke; move regularly; and take sleep and stress seriously, because the gut responds to both. None of this is exciting and all of it is better evidenced than most things sold for gut health.
How much does a gut health check cost?
A consultation is charged at our usual rates and may be claimable under CHAS or Healthier SG depending on your circumstances. FIT screening is subsidised for eligible patients. Microbiome profiling is a private test and is not claimable. Ask us at your appointment and we will set out what applies to you before anything is arranged.
When should I see a doctor urgently?
Blood in the stool, black or tarry stools, unexplained weight loss, a persistent change in bowel habit lasting more than a few weeks, persistent abdominal pain, difficulty swallowing, vomiting blood, or a lump in the abdomen. Any of these warrants prompt assessment rather than a home test.
