Almost everyone in India knows the feeling — that burning in the chest after a plate of chhole bhature, the sour taste creeping up after a late, heavy dinner. We reach for an antacid, call it “acidity,” and move on. Most of the time, that’s exactly the right response.
But for a sizeable number of people, that burning isn’t an occasional nuisance — it’s a near-daily event. And that’s where ordinary acidity ends and a treatable medical condition called GERD begins. Knowing the difference can save you years of discomfort, and in a few cases, something more serious.
What’s actually happening when you get “acidity”
Your stomach makes acid to digest food. A ring of muscle called the lower oesophageal sphincter — the valve between your food pipe and your stomach — is supposed to stay shut and keep that acid where it belongs. When it relaxes at the wrong moment, acid flows back up into the food pipe and irritates it. That’s the burning sensation we call heartburn, and the sour fluid that sometimes reaches the throat is called regurgitation.
A bit of reflux after a big or spicy meal is completely normal. The problem is when it keeps happening.
Acidity vs GERD: where’s the line?
Here’s a simple way to think about it:
Everyday acidity is occasional, usually linked to a specific trigger (a heavy meal, too much tea or coffee, a late dinner), and settles quickly with simple measures or an antacid.
GERD (Gastro-oesophageal Reflux Disease) is diagnosed when reflux happens at least twice a week, or when it starts causing complications. It’s chronic, it recurs, and it often needs proper treatment rather than just an antacid here and there.
If you find yourself buying antacids every week, propping yourself up at night to avoid the burning, or feeling it come back the moment you stop your medicine — that pattern points to GERD, not casual acidity.
The symptoms worth knowing
Typical reflux symptoms include:
A burning sensation behind the breastbone, especially after meals or when lying down
Sour or bitter fluid coming up into the mouth or throat
A persistent dry cough, often worse at night
An acidic or metallic taste in the mouth
A hoarse voice or sore throat in the morning
A sensation of a lump in the throat
Reflux can also masquerade as other things — a chronic cough, worsening asthma, or even chest pain (though chest pain should always be checked for a heart cause first).
The red flags — when acidity is not just acidity
This is the part to take seriously. Most acidity is harmless, but a few symptoms are “alarm features” that need prompt medical assessment, often with an upper GI endoscopy (https://dranandosengupta.com/ugi-endoscopy). See a doctor without delay if you have:
Difficulty or pain when swallowing
Unintentional weight loss
Vomiting blood, or black, tarry stools
Persistent vomiting
New reflux symptoms starting after the age of 50
These don’t mean something sinister is definitely present — but they are the signs a specialist needs to rule out complications such as ulcers, narrowing of the food pipe, or precancerous changes (Barrett’s oesophagus). Don’t self-treat your way past them.
Why it keeps happening to you
The reflux valve can weaken or misbehave for several reasons:
A hiatal hernia (part of the stomach slipping up through the diaphragm)
Excess abdominal weight, which pushes acid upward
Pregnancy
Smoking and alcohol
Certain medications, including some painkillers (NSAIDs), blood-pressure drugs and asthma inhalers
And then there’s the Indian plate. Common dietary triggers include spicy and oily curries and fried snacks (samosa, pakoda), tea, coffee and chocolate, carbonated cold drinks, and acidic foods like citrus, tomato, onion and mint. Late dinners and lying down soon after eating make it worse by letting gravity work against you.
What you can do at home first
For everyday acidity, these steps genuinely help — and they’re the foundation of GERD treatment too:
Eat smaller, more frequent meals instead of one heavy one
Stay upright for at least 2 hours after eating, and finish dinner about 3 hours before bed
Raise the head of your bed by around six inches (propping extra pillows under your head alone doesn’t work as well)
Lose 5–10% of body weight if you’re overweight
Cut back on your personal triggers — for most people that’s tea/coffee, fried food, cold drinks and late dinners
Stop smoking and limit alcohol
Over-the-counter antacids give quick, short-term relief, but they’re meant for occasional use — not as a daily crutch.
When to see a doctor
If your reflux happens twice a week or more, keeps coming back despite lifestyle changes, disturbs your sleep, or needs antacids almost every day, it’s time for a proper evaluation. And if any of the alarm features above are present, see a gastroenterologist promptly rather than waiting.
Good news: GERD responds well to treatment. A specialist will usually start with tailored diet and lifestyle advice plus a course of acid-reducing medication (such as a proton pump inhibitor), and most patients become symptom-free within a few weeks. An endoscopy is recommended when symptoms persist, are severe, or carry alarm features — not for everyone. Structured GERD and acid reflux treatment in Delhi (https://dranandosengupta.com/gerd) focuses on finding your specific triggers and getting you off the antacid-every-day cycle for good.
Occasional acidity is part of life. Constant, recurring heartburn is a signal worth listening to — because it’s usually very treatable once you stop guessing and get it assessed.
