In India, "gas" and "acidity" are almost a way of life. There is a chemist on every corner selling antacid sachets, digestive churan and acidity tablets, and most of us reach for one without a second thought after a heavy meal. For a one-off bout, that is perfectly reasonable.

The problem starts when "just acidity" becomes a daily habit. When the tablet only works until it wears off. When the bloating, the burning and the discomfort have quietly become part of your routine, and you have stopped questioning them. That is the point at which many Indians keep self-medicating for years, when what they actually need is a stomach doctor.

This guide explains when ordinary digestive trouble crosses the line into something that needs a gastroenterologist, what the warning signs are, and what actually happens when you see one.

Warning Signs Your Stomach Trouble Is Not Ordinary

Some digestive symptoms should never be managed with another strip of antacids. Each of the following can point to a condition that a stomach doctor needs to investigate properly.

See a stomach doctor if you have any of these

If you notice blood in your vomit or stool, or sudden severe abdominal pain, treat it as urgent and seek care immediately. For the slower warning signs like ongoing acidity, swallowing trouble or weight loss, book a gastroenterologist within days.

The Antacid Trap: When Self-Medication Hides a Problem

Acidity tablets and antacids work by reducing or neutralising stomach acid, and they genuinely relieve symptoms. But that relief is exactly what makes them risky when overused. They calm the burning without ever telling you why it is happening.

What long-term self-medication can mask

Conditions like acid reflux disease (GERD), stomach ulcers, an infection called H. pylori, and in rare cases more serious disease, can all feel like simple "acidity" in the early stages. Taking antacids for months can keep the symptoms quiet while the underlying cause continues. If you have needed acidity tablets regularly for more than 2 to 3 weeks, that is a signal to see a stomach doctor rather than buy another box.

Stomach Doctor vs General Physician vs Surgeon

It helps to know who does what, because patients often see the wrong doctor first and lose time.

A general physician is the right first stop for a short-lived stomach upset, a one-off infection or mild, occasional acidity. They can treat the common things well.

A stomach doctor or gastroenterologist is a specialist in the entire digestive system: the food pipe, stomach, intestines, liver, gallbladder and pancreas. They handle persistent, recurring or severe symptoms, and they perform investigations like endoscopy and colonoscopy to find the exact cause. Most digestive conditions are fully managed by a gastroenterologist with medication and lifestyle changes.

A GI surgeon only becomes involved when an operation is needed, for example for gallstones, a hernia or certain serious conditions. As with most specialties, you do not need to find a surgeon yourself. Your gastroenterologist will refer you only if surgery is genuinely required.

The simple rule: for occasional, mild symptoms, a general physician is fine. For anything persistent, recurring or alarming, go straight to a gastroenterologist. They are the specialist who can actually find the cause, not just settle the symptom.

Common Conditions a Gastroenterologist Treats

A stomach doctor deals with far more than acidity. These are some of the most common reasons Indians end up needing one.

Acid Reflux (GERD)
Frequent heartburn and acid coming up into the food pipe, often worse lying down
Stomach Ulcers
Burning pain, often linked to H. pylori infection or long-term painkiller use
IBS
Irritable bowel syndrome, with bloating, cramps and changing bowel habits
Fatty Liver
Increasingly common in India, often silent and found on a routine scan
Gallstones
Pain in the upper right abdomen, sometimes after fatty meals
Piles & Constipation
Long-standing constipation, bleeding or discomfort that needs proper assessment

What an Endoscopy Actually Involves

The word endoscopy makes many patients nervous, which is one reason they delay seeing a stomach doctor. In reality it is a quick and low-stress procedure, and it is often the fastest way to get a clear answer.

  1. Preparation: You are usually asked not to eat for a few hours beforehand so the stomach is empty
  2. Comfort: The procedure is done with mild sedation or a numbing throat spray, so you feel little or nothing
  3. The procedure: A thin, flexible tube with a tiny camera is gently passed through the mouth to view the food pipe and stomach. It takes around 10 to 15 minutes
  4. After: You rest briefly and most people go home the same day, often within an hour or two

For symptoms lower down, a colonoscopy works on the same principle to examine the large intestine. Both let the gastroenterologist see directly what is happening, rather than guessing from symptoms alone.

Frequently Asked Questions

What is the difference between a stomach doctor and a general physician?
A general physician can treat common, short-lived stomach complaints like occasional acidity or a stomach infection. A stomach doctor (gastroenterologist) is a specialist trained in the digestive system, including the food pipe, stomach, intestines, liver, gallbladder and pancreas. You need a gastroenterologist when symptoms are persistent, recurring or severe, or when an investigation like an endoscopy is required.
When should I stop taking antacids and see a doctor?
See a stomach doctor if you have been taking antacids or acidity tablets regularly for more than 2 to 3 weeks, if your symptoms keep returning the moment you stop, or if you also have warning signs like difficulty swallowing, weight loss, vomiting, blood in vomit or stool, or persistent pain. Long-term self-medication can mask a condition that needs proper diagnosis.
Is an endoscopy painful?
An upper endoscopy is usually not painful. It is a short procedure where a thin, flexible tube with a camera is passed through the mouth to look at the food pipe and stomach. It is commonly done under mild sedation or with a throat spray, takes about 10 to 15 minutes, and most people go home the same day. It is one of the most useful tools a stomach doctor has to find the exact cause of symptoms.
Which doctor should I see for liver problems or fatty liver?
A gastroenterologist, or a hepatologist where available, is the right specialist for liver conditions including fatty liver, which is increasingly common in India. If a routine scan or blood test has shown fatty liver or raised liver enzymes, a stomach and liver specialist can assess the cause, advise on diet and lifestyle, and monitor it so it does not progress.
What qualifications should a gastroenterologist in India have?
A qualified gastroenterologist in India holds MBBS, MD (General Medicine) and then DM (Gastroenterology), which is super-specialty training in the digestive system. A GI surgeon, who performs operations, holds MBBS, MS (General Surgery) and MCh (Surgical Gastroenterology). For non-surgical digestive problems, a DM Gastroenterology qualified stomach doctor is the right specialist.
