A woman came to my clinic last month with a folder so thick she needed both hands to carry it. Four endoscopies over three years. Two colonoscopies. An MRI. Blood reports from labs in Bangalore, Hyderabad, and Mumbai. A printed list of foods she had slowly cut out of her life. She sat down, opened the folder, and said, please just tell me what is wrong with me. In all my years of practising functional gut disease in Bangalore, I have heard a version of this same sentence almost every week.
Every report in that folder said normal.
I see a version of this story almost every week. After 30 years in healthcare, 25 of them spent actively operating, and around 25,000 surgeries along the way, the patients I find myself thinking about on the drive home are not the difficult cases on the table. They are the ones I could not help with a scalpel.
What functional gut disease really means (and why it does not mean fake)
We are trained to find things we can see. A stone, an ulcer, a tumour, a blockage, an inflamed patch. The whole logic of how we are taught works on the assumption that if a symptom is real, some test, somewhere, will show why. And for most of what I operate on, that is true. Piles, hernia, gallstones, appendicitis, colorectal cancer. You scan, you find it, you treat it, the patient gets better.
But there is a whole second group of patients in India who do not fit this model at all. Their gut is genuinely sick. They are not making it up. And nothing on any scan is going to show you why.
This is what we call functional gut disease, or more correctly, a disorder of gut-brain interaction. The structure of the bowel is fine. The way it behaves is not.
Functional does not mean fake
I have to say this clearly because patients in India hear the wrong version of it constantly. Functional is not a polite word for stress. It is not in your head. It is not because you are too sensitive or too anxious or because you should just calm down.
Here is what is actually happening. The muscles of your bowel can squeeze in patterns that are too strong, or too weak, or just badly timed. The nerves that line your gut, and there are millions of them, can become hypersensitive. Pressures that a normal gut would not even register start firing pain signals to your brain. And the constant back-and-forth conversation between your gut and your brain, what we call the gut-brain axis, gets stuck in a feedback loop.
The pain is real. The bloating is real. The five trips to the toilet before a flight are real. There is just no lesion to point a torch at, and that is what confuses both patients and a lot of doctors.
Conditions in this group include irritable bowel syndrome, functional dyspepsia, functional bloating, and functional constipation. Indian gastroenterology data suggests these are far more common here than people think, especially in working-age adults in cities.
Why a folder full of normal reports is actually good news
When patients with functional gut disease hand me their stack of normal reports, I tell them something they do not expect. This is actually the best place to start from, and it is the most common scenario I see in my Bangalore practice. That is the bar for functional gut disease care in 2026.
Normal scopes mean we have ruled out cancer. Normal blood work means no hidden inflammation, no anaemia, no thyroid problem hiding in the background. Normal scans mean no obstruction. Every dangerous thing is off the table. Now we can stop looking for what is not there and start treating what is.
The trap people fall into is repeating the same investigations every six months in different hospitals. It will not change anything. Functional gut disease is diagnosed by a doctor who actually sits down with you, takes a proper history, examines you, and knows the Rome IV criteria, which are the international standards for these conditions. It is not diagnosed by your fourth colonoscopy. If your main complaint is chronic constipation or acid reflux, the same logic holds.
What actually helps these patients
I will tell you what I have seen work, after a lot of trial and error in real Indian patients.
- A proper low-FODMAP food trial, but designed by a dietitian who eats Indian food and understands that you cannot just tell a Tamil family to give up onion, garlic, and dal in the same week. It has to be intelligent and temporary.
- Testing for small intestinal bacterial overgrowth, especially when bloating is the main thing. SIBO is underdiagnosed in India and very treatable when you find it.
- Medications that calm the gut-brain axis. These include certain antispasmodics and very low doses of nerve modulators. The low doses are not antidepressant doses, even though the drug name might be familiar, and I always explain this before the patient goes to the pharmacy and panics.
- The unglamorous things. Sleep at the same time every night. Drink water before you are thirsty. Eat at roughly the same time each day. Walk for thirty minutes. I know how boring this sounds. I have also watched it transform people who had given up hope.
- Honestly, finding a doctor who will give you thirty minutes of attention instead of three. A lot of healing in this field starts the moment a patient feels heard.
Things I would gently ask you to stop spending money on
• Repeat endoscopies every few months when nothing has changed since the last one.
• Those food intolerance blood test panels you see advertised online. The science behind most of them is genuinely poor.
• Random probiotic combinations bought because someone on Instagram suggested them. Some help, most do nothing, a few make bloating worse.
• Detoxes, cleanses, gut resets, and 21-day protocols. None of them have evidence behind them.
When you do still need to see a surgeon
I am a surgeon, so let me be straight with you. There are certain symptoms that should never be brushed off as functional, and you do need a proper opinion if you have any of them.
Bleeding from the back passage. Losing weight without trying. A lump you can feel. Vomiting that will not settle. A close family history of colon cancer. Symptoms that suddenly began after the age of fifty in someone who never had gut trouble before. These are red flags and they need scopes and scans, not reassurance over a phone call.
But for IBS, functional bloating, and functional dyspepsia, no operation will fix the problem. Not in this country, not in any country. The issue is in the wiring, not in anything that can be cut out. If anyone is offering you surgery for these conditions, please get a second opinion.
A more honest conversation for Indian patients
In most Indian families, gut symptoms are still spoken about quietly, if at all. Bloating gets blamed on the food. Loose motions on the water. Constipation on getting older. Pain on stress at work. So people put up with it for years before they walk into a clinic, and by the time they do, they have spent more money on the wrong tests than the right treatment would have cost in the first place.
You deserve better than that. A good gut health specialist in India today should be able to look at your normal reports, look at you, and tell you with confidence what is going on and how to live well with it. That is the bar.
If you are tired of carrying that folder from one specialist to another, our team treats functional gut disease as a real diagnosis, not a leftover category. You can book an appointment with our team here, or call +91 8431 550 550. We would rather you call once and not need us than wait another three years for an answer.
