Gas, Acidity, and a Stomach That Won't Settle: What's Actually Going On
Gas, Acidity, and a Stomach That Won't Settle: What's Actually Going On
Start with something you already know is true.
The morning of a board exam, half the hall has been to the toilet twice. The night before a wedding, somebody in the family isn’t eating. Before a job interview, before a court date, before a flight — the stomach knows first, and it knows before you’ve admitted to yourself that you’re nervous.
Nobody calls that imaginary. Nobody tells a student on exam morning that his loose motions are in his head.
So here’s the question this page is about. What happens when that mechanism doesn’t switch off? When it isn’t one morning before one exam, but every morning, for two years?
That’s not a different phenomenon. It’s the same one, running continuously. And the discomfort is exactly as real as it was on exam morning — which is to say, completely.
Before anything else
Some stomach symptoms need investigation, not explanation. Please see a doctor without delay if any of these apply:
- Blood in the stool, or black tarry stools
- Weight loss you didn’t intend
- Difficulty or pain on swallowing
- Persistent vomiting
- Symptoms that wake you from sleep
- A lump or swelling you can feel in the abdomen
- Low haemoglobin
- Fever along with the symptoms
- New symptoms starting after around the age of forty-five or fifty
- A family history of bowel cancer, coeliac disease, or inflammatory bowel disease
None of those are described anywhere on this page as stress. They need a doctor, tests, and a proper answer.
This matters more here than in most places, because stomach symptoms don’t frighten people the way chest pain does. Nobody rushes to a hospital over gas. They buy something at the chemist and carry on — sometimes for years — and that is how serious disease gets found late. If you’ve had these symptoms for a long time and never been properly examined, please start there and not here.
The short answer
Your gut has its own nervous system. Hundreds of millions of nerve cells in the wall of the digestive tract, wired directly to the brain, talking in both directions all day.
When that line gets busy — stress, fear, exhaustion, months of running on empty — the gut changes how it behaves. It moves faster or slower. It secretes differently. And it becomes more sensitive, so that an ordinary amount of gas, which you’d normally never notice, registers as pain.
That last part is the whole thing. It usually isn’t that there’s more gas. It’s that the volume has been turned up on sensations that were always there.
This has a name in gastroenterology now — these are classed as disorders of gut-brain interaction, which is a considerable improvement on what they used to be called. A real, recognised, mechanically understood problem. Not a diagnosis of exclusion, and not a polite way of saying nothing’s wrong.
Why "all reports normal" doesn't mean nothing is wrong
An endoscopy looks at the lining. A scan looks at structure. Blood tests look at inflammation and chemistry.
None of them measure how the gut is behaving. None of them measure sensitivity.
So a person can have a perfectly normal endoscopy and a gut that is genuinely, measurably over-reactive — and there’s no picture that shows it. The reports aren’t wrong. They’re answering a different question from the one you’re asking.
Which is why “everything is normal” is such an unsatisfying sentence to be handed. It’s true, it explains nothing, and you’re left standing in the corridor holding it.
What it actually looks like
Most people have some mixture of:
Gas and bloating that worsens through the day. Flat stomach in the morning, tight and distended by evening. Often worse after meals, often eased a little by passing gas or opening the bowels.
Pain or discomfort that moves around, changes character, and settles after going to the toilet.
Bowels that swing — loose some days, constipated others, sometimes both in one week. Urgency in the morning, especially before something stressful.
Acidity and burning that doesn’t fully respond to antacids, or comes straight back when you stop them.
Fullness after a few bites, then heaviness for hours.
Nausea, especially in the morning.
And a pattern almost everyone recognises once it’s pointed out: it’s better on holiday. Better on a Sunday. Worse on Monday morning, worse before travel, worse in the weeks before an exam or a hearing or a difficult conversation.
If your stomach has a calendar, that’s information. It’s not proof of anything by itself, and it’s worth telling your doctor.
The antacid trap
Worth saying directly, because it costs people years.
A lot of people end up taking something for acidity more or less permanently — started by a doctor for a few weeks, or bought over the counter, and then simply never stopped. Some of that is entirely appropriate treatment for a real acid problem. But a good proportion of the burning, fullness and discomfort treated this way isn’t primarily an acid problem at all, which is why it never fully goes and why it returns the moment the tablets stop.
Two things follow.
First — if you’ve been taking something for the stomach for months or years without a review, that’s worth an appointment. Not to stop it on your own. To have someone look at whether it’s still the right thing.
Second — please don’t stop long-term stomach medication abruptly by yourself. Some cause a rebound when stopped suddenly, and you’ll conclude the symptoms are worse than they are.
No medicine is named anywhere on this site. Your doctor knows what you’re on.
What actually helps
Get properly assessed first, once. This is not a page telling you to skip investigations. It’s a page for after them.
Eat regularly. Skipping meals all day and then eating a large one at ten at night is very common and very hard on a sensitive gut. The boring recommendation that helps more people than the interesting ones.
Be careful with elimination diets. Some structured dietary approaches do have real evidence behind them for gut-brain disorders — but they’re meant to be short, supervised, and followed by proper reintroduction. What tends to happen instead is that people cut out one food after another based on a bad day, and end up eighteen months later eating almost nothing, still symptomatic, and now genuinely short on nutrition. If a dietary approach is worth trying, it’s worth doing with a dietitian. Cutting things out alone is the version that goes wrong.
Move. Regular physical activity changes gut motility measurably. One of the few things that helps both the gut and whatever’s sitting underneath it.
Ask about gut-directed talking therapy. This surprises people, so let me be clear: there are structured psychological treatments developed specifically for gut symptoms — not general counselling, and not “learn to relax.” They work on the gut-brain line directly, and gastroenterology guidelines now recommend them for symptoms that haven’t settled with standard measures. Not widely available in India yet. Still worth asking about.
Deal with what’s underneath, if something is. In a fair number of people the gut is the loudest part of an anxiety problem, or a low mood nobody has named. Treating the stomach alone in that situation is like mopping the floor with the tap running.
Things worth ruling out first
Some of these are common in India and get missed, so it’s reasonable to ask about them by name:
- Coeliac disease— commoner here than most people assume, particularly in the north, and often mistaken for years of “gas trouble.”
- Lactose intolerance— very common in adults across much of Asia, and easy to check.
- pylori infection.
- Giardia and other parasitic infections— especially if loose motions began after a specific illness or trip.
- Inflammatory bowel disease.
- Thyroid problems— both directions affect the bowel.
- Medicines you’re already takingfor something else. Several common ones produce exactly these symptoms.
And one more. If all of this began after an episode of food poisoning or gastroenteritis, say so. Gut symptoms that persist long after an infection has settled are a recognised pattern with a name of their own, and it changes how the problem is understood.
A story that isn't one person's
The following is a fictional example, assembled from patterns commonly seen in practice. It is not any real patient.
A woman in her early forties. “Gas problem” since roughly the year her father-in-law’s illness began.
Three endoscopies over six years. Two ultrasounds. A colonoscopy after a particularly bad stretch. Everything normal, every time. Something for acidity, taken more or less daily for four years, originally started for two weeks.
She’d stopped eating out. Then stopped wheat, on somebody’s advice. Then dairy. Then most vegetables that “made gas,” which by then was most of them. She had a mental list of about nine safe foods and she was still bloated by evening.
What nobody had asked, in six years, was when it was better.
It was better in May. Every year, the three weeks she spent at her mother’s.
That wasn’t the whole answer and it fixed nothing by itself. But it was the first time anyone had suggested her stomach might be responding to something rather than failing at something — and the first time in six years she’d stopped feeling that the problem was her.
What to do this week
- If you’ve never been properly examined, do that first.Everything else comes after.
- Check your symptoms against the list at the top of this page.Any of those, and it’s a doctor, now.
- Keep a rough note for two weeks— which days are bad, what’s happening in your life on those days, and what you’d eaten. Not to find the culprit food. To see whether there’s a pattern that isn’t about food at all.
- Stop adding foods to the banned list.If you’re down to a handful of safe foods and still symptomatic, the elimination approach isn’t working, and it’s now creating a second problem.
- Book a review of any long-term stomach medication.Don’t stop it yourself.
- Notice whether it’s better on holiday.Then say that to your doctor, out loud. It’s the single most useful sentence most people never think to mention.
When to see a doctor
- Any of the symptoms in the block at the top of this page —
- Symptoms have gone on for months and you’ve never had a proper examination.
- You’ve been on something for the stomach long-term without a review.
- Your list of foods you can eat keeps shrinking.
- Sleep, mood or worry have changed alongside the gut symptoms.
- It’s affecting work, travel, or whether you’ll leave the house.
- You’ve stopped believing anybody is going to take it seriously. That one’s worth an appointment too, and it’s commoner than people admit.
Seeing a psychiatrist about stomach symptoms doesn’t mean anyone has decided they’re imaginary. Usually it means somebody has finally worked out which system is doing the shouting.
