IBS: What a Homoeopath Asks About Your Gut That a Scan Cannot Show
Being told every test is normal is meant to be reassuring. For most people with IBS it is the opposite.

IBS is a disorder of gut function rather than gut structure, which is why endoscopy, colonoscopy and scans come back normal. The problem lies in how the gut moves, how sensitive its nerves are, and how it communicates with the brain, none of which a camera can see. A normal scan does not mean nothing is wrong. It means the problem is of a kind that imaging does not detect.
The most demoralising sentence in this whole area is "everything came back normal". It is intended as good news and it very often lands as dismissal, because the person is still in pain and has just been told there is nothing to find.
Both things are true at once, and understanding why is the beginning of getting somewhere.
Why the camera sees nothing
A colonoscopy is very good at finding things that alter the appearance of the bowel wall: ulcers, inflammation, growths, narrowing. IBS alters none of those.
What it alters is how the muscle in the wall contracts and how loudly the nerves in the wall report sensation.
A useful comparison is a migraine. Nobody expects a brain scan to show a migraine, and a normal scan does not mean the headache was imagined.
The gut works the same way, and the tests exist to exclude the things that do show up, which is a genuinely valuable thing to have done.
The gut and the brain, without the mysticism
The gut contains a very large network of nerve cells embedded in its wall, capable of running digestion largely on its own, and in continuous two way communication with the brain. This is ordinary physiology rather than anything exotic.
It explains several things people notice and are rarely told are expected. Anxiety producing genuine diarrhoea.
Symptoms flaring in a hard week and easing on holiday. Pain that is worse when attention is on it.
None of that means the illness is psychological. It means the organ involved is wired to the nervous system, which is not a character flaw.
What is still worth testing
- Coeliac disease. The most important one, because it is genuinely treatable and its symptoms overlap almost completely with IBS. Test before removing gluten, because the test only works while you are still eating it.
- Full blood count. Anaemia is never part of IBS and points somewhere else.
- Inflammatory markers, and a stool test for inflammation where available, which helps separate IBS from inflammatory bowel disease.
- Thyroid function, since both overactive and underactive thyroid change bowel habit.
- Parasites and infection where the history suggests it, which in India is worth taking seriously particularly after travel or a gastrointestinal illness.
IBS is a positive diagnosis based on a recognisable pattern, not simply what is left when tests are normal. But those tests genuinely matter, because the conditions they exclude are treated completely differently.
A ninety minute case history looks at the pattern, the triggers and the person, which is exactly what imaging cannot do.
IBS is diagnosed partly by the absence of these. Any of them changes the picture.
- Blood in the stool, or black tarry stool.
- Weight loss you did not intend.
- Symptoms that wake you from sleep, particularly diarrhoea at night.
- A first onset of these symptoms after the age of about fifty.
- Fever, or a mass felt in the abdomen.
- Anaemia on a blood test, which is never part of IBS.
- A family history of bowel cancer, coeliac disease or inflammatory bowel disease.
- Progressive worsening rather than the fluctuating pattern typical of IBS.
The subtypes, and why they matter
| Type | Predominant symptom |
|---|---|
| Diarrhoea predominant | Loose or urgent stools, often soon after eating or on waking |
| Constipation predominant | Hard stool, straining, incomplete emptying, bloating |
| Mixed | Alternating between the two, often unpredictably |
| Post infectious | Began after a gastrointestinal infection and never fully settled |
These are managed differently, which is one reason generic IBS advice so often fails. Advice aimed at constipation makes the diarrhoea type worse and the reverse is also true.
On elimination diets, honestly
There are structured dietary approaches to IBS with reasonable evidence behind them. The important word is structured.
They are designed to be followed with guidance for a limited period and then systematically reintroduced, and the reintroduction is the part that matters.
What happens in practice is that people find the restriction list online, follow it indefinitely, feel somewhat better, and end up eating twelve things while their gut bacteria narrow and their social life shrinks. If you are going to do this properly, do it with somebody guiding it and put a date on the reintroduction.
What classical homoeopathy asks that the scan did not
The scan asked what the bowel looks like. The consultation asks how this person works.
What time of day symptoms come. Whether they are worse before events, and which events.
What happens to appetite under strain. Whether the person is hot or chilly, thirsty or not, restless or still when unwell.
How they sleep. What was happening in their life when this started, which with post infectious IBS is often a very specific and rememberable episode.
That is not a substitute for the tests, and anybody who tells you the tests were unnecessary is wrong. It is a different set of questions aimed at the person rather than the organ, which is a reasonable thing to do for a condition defined by disturbed function in a nervous system that belongs to somebody.
The remedy follows the individual, so none is named here. Realistic aims are fewer and milder flares, more predictability, and a wider range of food tolerated.
If a fair trial changes nothing, that should be said plainly. The digestive conditions page covers the wider approach, and the blog on bloating covers the symptom people find hardest to live with.
Common questions
Why is my colonoscopy normal if I have IBS?
Because IBS is a disorder of how the gut works rather than how it is built, and a camera can only see structure. It alters how the muscle contracts and how loudly the nerves report sensation, neither of which changes the appearance of the bowel wall. A normal scan rules other things out rather than ruling IBS out.
Does IBS mean my symptoms are psychological?
No. A functional disorder means the structure is intact and the working is disturbed, and the pain comes from real nerves carrying real signals. The gut has its own large nerve network in constant communication with the brain, which is ordinary physiology and explains why symptoms flare under strain.
What tests should I have before accepting an IBS diagnosis?
Coeliac disease is the most important, because it is treatable and its symptoms overlap almost completely. Test before cutting out gluten, since the test only works while you are still eating it. A full blood count matters too, because anaemia is never part of IBS and points elsewhere.
Which symptoms mean it is not IBS?
Blood in the stool, black tarry stool, unintended weight loss, symptoms that wake you at night, first onset after about fifty, fever, a mass in the abdomen, anaemia on a blood test, or steady progressive worsening rather than a fluctuating pattern. Any of those needs investigating.
Can homoeopathy help IBS?
Classical homoeopathy asks a different set of questions from the scan, aimed at the person and the pattern rather than the organ, which is reasonable for a condition defined by disturbed function. It does not replace the tests. Realistic aims are fewer and milder flares and more predictability.
