Discover some of the acidity-like symptoms of a heart attack; know the signs of gas pain as opposed to a heart attack; and know the warning signs that chest pain requires emergency treatment.

Introduction

After eating something spicy, I felt a burning sensation. Some fullness in the chest. Lots of gas and burping.

People in India discuss such symptoms as “gas” or “acidity”. Many times they can originate in the digestive system. However, there's an Achilles' heel, as heart problems may sometimes feel very much like indigestion or heartburn.

Feeling a severing of the chest doesn't necessarily mean you are having a heart attack. In some cases the individuals feel discomfort, nausea, unusual tiredness, difficulty breathing, dizziness or intense pain in the upper abdominal area, back, jaw or arm. During a heart attack there are symptoms to consider that include heartburn and indigestion (What Is a Heart Attack?, n.d.).

This overlap is what makes World Heart Day 2026 a handy reminder to differentiate between usually burbling digestive issues and at times fatal signals from your heart.

If chest pain is new/untypical, suspect that it might be cardiac in origin; don't attempt diagnosis at home. Go for emergency medical treatment.

World heart day 2026: Why this conversation matters

On September 29th each year, World Heart Day is celebrated to raise awareness about cardiovascular diseases and promote action for cardiovascular health.

The problem is important, especially in countries like India, which is a big hit on heart diseases. According to the WHO, cardiovascular disease is the top leading cause of death worldwide; some of the important modifiable risks are high blood pressure, unhealthy diet, lack of physical activity, smoking and harmful drinking (World Health Organization: WHO, 2025).

Hypertension is another significant disease in India. According to WHO India, hypertension is one of the most significant cardiovascular risk factors prevalent in India and stresses regular monitoring of blood pressure, healthy lives and even proper treatment (World Health Organization: WHO, 2020).

The lesson is very simple:

Don't wait till you have a heart attack to take heart health seriously.

Heart attack symptoms mistaken for acidity

Actually, the signs that are associated with a heart attack have often been confused with cases of acidity.

The heart and oesophagus are housed in the chest in a relatively close position to each other.

That's why the discomfort from the digestive tract might sometimes be confused with heart discomfort. The heartburn is typically caused by the stomach contents rising up into the oesophagus, which brings about a heat sensation behind the breastbone.

The causes are completely different.

The sensations aren't always dramatically different.

Heartburn and heart-related chest discomfort can be difficult to distinguish and recommends seeking medical attention when you're unsure (Clinic, 2025)

Heart attack vs acidity

There are clues that can make one explanation more likely, but no symptom checklist can reliably rule out a heart attack.

Feature

More typical of acidity/heartburn

More concerning for a heart problem

Timing

Often after meals

May occur during exertion or at rest

Sensation

Burning behind breastbone

Pressure, squeezing, heaviness, aching

Mouth

A sour or acidic taste may occur

Usually absent

Position

May worsen lying down or bending

Often unrelated to position

Relief

May improve with antacids

Shouldn't be assumed to improve with antacids

Radiation

Usually localized

May spread to arm, jaw, back, neck, or upper abdomen

Associated symptoms

Regurgitation, bloating

Breathlessness, sweating, nausea, dizziness, unusual fatigue

Can acidity feel like a heart attack?

Yes, severe heartburn can cause significant burning or discomfort in the chest and may feel frighteningly similar to cardiac pain.

Typical heartburn often

  • Appears after eating

  • Gets worse when lying down

  • Gets worse when bending over

  • Comes with a sour or bitter taste

  • May involve food or acid coming back into the throat

But the above-mentioned features do not ensure that the discomfort is not harmful.

Nausea, vomit, or discomfort in the upper abdominal region may also be experienced during a heart attack and are all symptoms that could be mistaken for just heartburn.

So, yes, if you have a new, intense, atypical or uncalled-for chest pain, the best answer is 'Treatment first, guesswork later; get assessed medically.'

Gas pain or heart attack?

Gas may build up in the abdomen, make it hard to breathe, make one feel full, cause belching, and result in discomfort.

That pain sometimes can ascend to cause pressure around the chest.

However, there's a bad consumer model that anyone can fall into:

My tummy makes noise, it has no heart; it can't be my heart.”

It's a dangerous assumption to make.

Some may experience heart attack symptoms such as indigestion, heartburn, nausea or feeling full or bloated. Indigestion-like sensations are one of the symptoms of a heart attack (NHS, 2026).

If the pain is accompanied by any of the following, treat it as an emergency: Shortness of breath, sweating, faintness, or pain in the arm, jaw, neck, back or upper abdomen.

What does a silent heart attack feel like?

It can be quite confusing to term a heart attack as a "silent heart attack".

Your symptoms may not be severe enough to recognise as related to a heart attack, or you might have them and not realise they are a sign of a heart attack.

Some people may experience:

  • Unusual fatigue

  • Mild chest discomfort

  • Shortness of breath

  • Nausea

  • Indigestion-like discomfort

  • Dizziness

  • Sweating

  • Back, jaw, or upper-abdominal discomfort

Some heart attacks can even occur without obvious symptoms. WHO notes that underlying cardiovascular disease can remain silent until a heart attack or stroke occurs (World Health Organization, 2025).

That is why the term “silent” doesn't mean harmless.

Silent heart attack symptoms that people in India may overlook

Certain symptoms are particularly easy to misinterpret as digestive trouble.

1. Unusual indigestion

A sudden episode of unexplained indigestion may be harmless. But if it appears with other cardiac symptoms, don't dismiss it as acidity.

2. Upper-abdominal discomfort

Heart-related discomfort can sometimes be felt in the upper abdomen rather than directly over the heart.

3. Unusual fatigue

Extreme or unexplained tiredness can accompany heart attacks. Women may be more likely to experience unusual fatigue and other less-classic symptoms (American Heart Association, 2025).

4. Breathlessness

Shortness of breath can occur with or without obvious chest pain.

5. Nausea or sweating

Sometimes, a heart attack is accompanied by nausea, vomiting, cold sweating, or lightheadedness.

The combination of these symptoms is more worrisome.

Signs of a heart attack that feel like acidity

It is important not to allow the pain to intensify to the point that it can no longer be tolerated.

If indigestion-like discomfort is accompanied by any of the following, seek emergency medical help:

  • Causes of pain related to chest squeezing/pressure

  • Place where pain radiates (arm, jaw, neck, back or abdomen)

  • Shortness of breath

  • Cold sweating

  • Dizziness or faintness that comes on quickly

  • Invariable inattention or laziness

  • Nausea or vomiting

What should you do if you suffer from chest pain, acidity or heart problems? 

When in doubt, don't try alternative remedies at home to determine if the pain goes away.

Do not think it is gas just because recently you ate.

Don't assume it's acidity because you've experienced reflux before.

And don't drive yourself to the hospital if emergency transport is available.

If You Suspect a Heart Attack

  1. Call your local emergency medical service immediately.

  2. Stop physical activity and sit or rest.

  3. Follow instructions from emergency medical personnel.

  4. Don't delay emergency care while trying antacids or home remedies.

  5. If you're with someone experiencing symptoms, stay with them until help arrives.

Who should take heart symptoms especially seriously?

Risk isn't determined by age alone.

Heart disease risk can increase with factors such as the following:

  • High blood pressure

  • Diabetes

  • High cholesterol

  • Smoking

  • Obesity

  • Physical inactivity

  • Family history

  • Increasing age

  • Unhealthy diet

How to protect your heart every day

World Heart Day isn't only about recognising emergencies.

It's also about preventing them.

Build these habits

  • Take your blood pressure frequently.

  • If you're at risk, check your blood glucose.

  • Become familiar with your cholesterol levels.

  • Don't smoke or use tobacco.

  • Stay physically active.

  • Enjoy increases in vegetables, fruits, whole grains and other 'less processed' foods.

  • Limit excess salt.

  • Keep a healthy weight!

  • Follow medical prescriptions for drugs.

  • Go to recommended health fees.

Conclusion

Acidity is common, and making gambles is no way to treat heart attacks.

This can be in surprisingly subtle ways, which is why sometimes people think that if someone has cardiac symptoms, it's gas, indigestion, or acidity.

Typical symptoms of a heart attack are chest pain, discomfort, or pressure; shortness of breath; clamminess and sweating; nausea; dizziness; unusual tiredness; and pain in the arm, jaw, neck, back, or upper abdomen.

World Heart Day 2026 is about more than just another health slogan; it's about taking action to save lives.

It's this: Don't guess if the symptoms appearing on the chest are new or unexplained. Get checked. You can't always feel your heart giving a warning. Sometimes, it whispers.

FAQs

What is the difference between gas and a heart attack?

Symptoms are very unreliable and will not usually indicate with certainty. Sometimes a person can also have a gas complaint that has heart symptoms and new or unexplained chest pain, particularly if it is accompanied by more severe shortness of breath, sweating, dizziness, nausea or other pain spreading to other areas; it should be assessed promptly by a medical professional.

The usual symptoms of a heart attack are confused for signs of acidity.

During a heart attack, indigestion, heartburn, upper gut pain, nausea and bloating can sometimes happen, as well as burning sensations.

Can acidity feel like a heart attack?

Yes. Chest pain associated with severe heartburn may be similar to heart pain. Illnesses are often confused, and individuals should not make their own diagnosis; any unexplained or troubling chest pain needs to be evaluated.

How can you tell you've had a silent heart attack?

Sometimes presents with more general or abnormal symptoms of tiredness, nausea, indigestion, shortness of breath, dizziness or chest, back, jaw or upper abdomen discomfort. There are individuals who have virtually no symptoms.

When is pain in the chest due to acidity vs. a heart problem?

It is impossible to find out the cause of the sensation. If pain is new, unexplained, severe, persistent or accompanied by other worrisome signs, seek emergency treatment.
