What Causes Heartburn? A Complete Guide

Heartburn — just the name itself sounds uncomfortable, right? It's that burning sensation in your chest that creeps up, especially after a heavy meal or late-night snacks. In India, where food is full of spice, flavor, and fried goodness, heartburn is surprisingly common, yet rarely talked about openly. Most people just pop a cold drink or antacid and move on, not realising that recurring heartburn could be a sign of something more serious.

If you've ever felt a weird heat rising up from your stomach to your throat, you're not alone. Whether it's from eating oily samosas, too much chai, or having dinner right before bed, these little habits can pile up and cause that burning to come back again and again. But don’t worry — this guide will walk you through everything from common heartburn causes to foods that trigger it, and what you can actually do about it (without giving up all your favorite Indian dishes!).

Let’s break it all down, step by step.

Understanding Heartburn

What is Heartburn?

Heartburn isn’t actually about your heart — despite the name. It’s a digestive issue caused when stomach acid flows back up into the esophagus (the tube that connects your mouth to your stomach). This backflow, also called acid reflux, irritates the lining of your esophagus and causes that familiar burning feeling in your chest, sometimes reaching the throat.

How Does Heartburn Feel?

People describe it differently. For some, it feels like a sharp burning in the middle of their chest, especially after eating. For others, it’s more of a sour taste in the mouth, a mild cough, or even bloating. You might even think you’re having a heart problem, which can be scary. But unlike a heart attack, heartburn usually worsens after meals and improves when you stand or sit up.

Is Heartburn Common in India?

Yes, and probably more than you think. Spicy foods, irregular eating times, and stressful lifestyles make Indians prone to digestive issues. But because many people treat it casually, they don’t always seek proper advice or treatment. According to some recent surveys, more than 30% of Indians experience acid reflux symptoms at least once a week. That’s quite a lot!

Main Causes of Heartburn

What is the Main Cause of Heartburn?

The root cause of heartburn is a weak lower esophageal sphincter (LES) — this is the valve that separates the stomach from the esophagus. When it doesn’t close properly, acid escapes upwards, leading to reflux.

But why does it become weak? There are many reasons, and they’re not always obvious.

Why Did You Get Heartburn?

Let’s be honest — sometimes it’s just those late-night biryanis or that extra spoon of achaar that does it. But there’s more:

• Overeating or eating too fast: Common during weddings or festivals.

• Lying down right after meals: A typical habit, especially post-lunch naps.

• Smoking and Alcohol: Both relax the LES and increase stomach acid.

• Obesity: Being overweight puts extra pressure on your abdomen.

• Stress: Yep, mental stress affects digestion too. It’s all connected.

Foods That Cause Heartburn

Now let’s get to the part that really hits home — the food. Indian cuisine is undeniably delicious, but it's also full of potential heartburn triggers. That doesn’t mean you have to give up your favorite dishes, but being aware of what may be causing discomfort can help you manage symptoms better.

Spicy Indian Foods (e.g., pickles, chutneys, curries)

Let’s start with the obvious — spice. That mirchi tadka you love? It can irritate the esophagus and relax the LES, leading to acid reflux. Pickles, spicy chutneys, and even rich gravies can cause trouble. Eating them occasionally is fine, but overdoing it? Not so much.

Oily and Fried Snacks (samosas, pakoras, etc.)

Deep-fried snacks like samosas, bhajiyas, kachoris, and pakoras are heavy on the stomach. They slow digestion, increasing the chances of acid backing up. Plus, they often come with spicy chutneys, making the combo even worse for your gut.

Caffeinated and Carbonated Drinks

Tea and coffee — especially strong masala chai — are beloved in India. But caffeine can relax the LES, making it easier for acid to escape into the esophagus. Fizzy drinks? Double trouble. They not only increase acidity but also add gas and bloating into the mix.

Citrus Fruits and Tomato-Based Gravies

Oranges, lemons, and tomatoes are naturally acidic. When consumed in excess — especially in curries, sambhars, and chutneys — they can aggravate reflux symptoms. It doesn’t mean you can’t eat them, just balance and timing matters.

Chocolate and Mint

This might surprise you — chocolate and mint both relax the LES. That after-meal mint candy or chocolate dessert might seem harmless, but for some people, it’s a quick road to reflux. Sad, I know. But not all good things come without cons.

Tips to Manage Diet and Avoid Triggers

You don’t need to switch to bland boiled veggies overnight. Here are a few realistic (and very Indian) tips:

• Have smaller, more frequent meals.

• Don’t lie down immediately after eating. Wait at least 2 hours.

• Limit spicy and oily food to special occasions.

• Try herbal teas like ginger or chamomile instead of regular tea sometimes.

• Add a bit of saunf (fennel seeds) after meals — it's an old-school remedy that still works.

Medical Conditions That Can Cause Heartburn

Heartburn isn’t always about what you eat. Sometimes, the issue lies deeper.

GERD (Gastroesophageal Reflux Disease)

If you experience heartburn more than twice a week, you may be dealing with GERD. It’s a chronic form of acid reflux that needs medical attention. Left untreated, it can damage the esophagus and affect quality of life. It’s more common in urban India than you’d think.

Hiatal Hernia

This occurs when part of the stomach pushes through the diaphragm into the chest. It makes it easier for acid to escape and leads to frequent heartburn. Though not very common, it's still seen in some patients, especially those over 40.

Pregnancy-related Heartburn

Many Indian women experience heartburn during pregnancy due to hormonal changes and pressure on the stomach. It’s temporary, but can be quite uncomfortable. Avoiding heavy meals, sleeping upright, and having milk may help.

Certain Medications

Some commonly used medicines — like painkillers, blood pressure meds, and even antibiotics — can cause acid reflux as a side effect. Always check with your doctor if symptoms start after starting a new medication. (Don't self-diagnose — Google isn’t always right.)

Heartburn Triggers in Indian Lifestyle

Food isn’t the only villain in the story. The way we live also plays a big role in digestive health — and heartburn. In India, where routines can get chaotic and stress runs high, certain lifestyle habits silently make things worse.

Irregular Meal Timings

Skipping breakfast, late lunches, and dinner at 11 pm — sound familiar? These erratic patterns confuse your digestive system and increase acid buildup. When you don’t eat for long hours and suddenly have a heavy meal, the stomach goes into overdrive. Acid reflux often follows.

Late Dinners and Bedtime Snacks

A lot of us eat dinner while watching TV at night, then crash into bed right after. Bad idea. Lying down too soon allows acid to move more freely into the esophagus. Ideally, finish your last meal at least 2–3 hours before lying down.

Stress and Lack of Sleep

You’d be surprised how much your gut is connected to your mind. High stress levels increase stomach acid production. Sleep deprivation also throws your hormones off balance. Together, they create the perfect environment for heartburn to thrive.

Fast Food and Junk Food

The growing love for burgers, pizzas, instant noodles and street food across India is also increasing digestive problems. These foods are loaded with fats, salt, and preservatives — all triggers for acid reflux. They’re okay once in a while, but not as a daily affair.

How to Make Heartburn Go Away

So, what can you actually do when heartburn hits?

Home Remedies Common in Indian Households

1. Cold milk: A glass of plain cold milk can neutralize acid quickly. Avoid flavored or sweetened versions.

2. Saunf (fennel seeds): Chewing on a teaspoon after meals can ease digestion and reduce bloating.

3. Ajwain water: Ajwain (carom seeds) boiled in water is an age-old remedy. Sip it warm.

4. A pinch of baking soda in water – works fast, but don’t overuse it.

OTC Medications and When to Use Them

Over-the-counter antacids, H2 blockers, or proton pump inhibitors (PPIs) can offer relief. But don’t rely on them for weeks without medical advice. Chronic use can lead to side effects — or mask bigger problems.

Lifestyle Changes to Prevent Heartburn

• Maintain a healthy weight.

• Elevate the head of your bed slightly.

• Wear loose-fitting clothes (tight waistbands make it worse).

• Avoid smoking and limit alcohol.

• Do light walks after meals — even 10 mins can help.

When to See a Doctor

If you're popping antacids more than 2–3 times a week, or if symptoms keep returning, it’s time to consult a gastroenterologist. Long-term reflux can damage the esophagus and lead to serious issues like ulcers or even cancer in rare cases. Better safe than sorry, na?

FAQs About Heartburn

What is the main cause of heartburn?

The main cause is acid reflux, where stomach acid escapes into the esophagus. This happens when the valve (LES) weakens or relaxes at the wrong time — often due to spicy food, late meals, or lifestyle habits.

How do you make heartburn go away?

Quick fixes include drinking cold milk, chewing saunf, or taking an antacid. For long-term relief, eat light meals, avoid triggers, stay active, and reduce stress.

Why did you get heartburn?

Could be your last meal, your stress levels, or just lying down too soon after eating. Triggers differ for everyone — keep track of what sets yours off.

Can heartburn be a sign of something serious?

Sometimes, yes. If it's frequent or severe, it could indicate GERD or even ulcers. If it feels like chest pain or is accompanied by vomiting or weight loss, don’t ignore it — see a doctor.

Does heartburn mean acid reflux or GERD?

Heartburn is a symptom of acid reflux. If it happens often, it might be GERD — a chronic, more serious form that needs treatment.

Conclusion

Heartburn might feel like a small problem, but if ignored, it can disrupt daily life. The good news? You don’t have to give up all your favorite foods or traditions to manage it. With small changes, some wisdom from grandma’s kitchen, and a bit of awareness, you can keep your gut happy — and your heartburn at bay.
