Difference Between Heartburn and Acid Reflux

Heartburn vs. Acid Reflux: How They Differ?

The terms heartburn and acid reflux are often interchangeably used even though they are entirely different from each other. Both of them are health conditions, and you’ll experience various symptoms for each of them. However, some symptoms may overlap.

In this heartburn vs. acid reflux guide, we’ll discuss the differences between both so that it’s easy for you to identify both.


Heartburn vs. Acid Reflux: An Overview

Acid reflux is a health condition where the patient will experience symptoms like a bitter taste in the mouth, upset stomach, nausea, belching, feeling full, bloated abdomen or stomach, dry cough, hoarseness, wheezing, and more.

On the other hand, heartburn is only a symptom of acid reflux. Heartburn can be caused even without acid reflux. Patients affected with heartburn feel a sharp, burning sensation in the chest.


What Is Heartburn?


Heartburn is a misleading term because this condition has nothing to do with your heart. It is called heartburn because people only ‘feel’ the sensation in their hearts.

In reality, it’s caused by your esophagus. The acid in the lining of your esophagus causes a burning sensation in your chest, and that can feel like a tight, burning sensation.

Because this is felt in the chest region, many people mistake this for heart attack pain. Hence it’s termed heartburn.


What Is Acid Reflux?

acid reflux

It’s a simple yet common health condition that allows the acid from your stomach to escape outwards. There’s a circular muscle that joins your esophagus and stomach known as Lower Esophageal Sphincter (LES).

This muscle tightens after food intake so that the food particles and the acid can’t escape into your esophagus.

However, if this muscle fails to close the opening properly due to being weak, the acid escapes backward to your esophagus, leading to multiple symptoms, including heartburn.


Difference Between Heartburn and Acid Reflux

Let’s take a look at the key differences between heartburn and acid reflux.


The causes behind heartburn and acid reflux can be the same, as heartburn is itself a cause of acid reflux.

That only means that if you experience heartburn, you’re suffering from acid reflux as well. However, suffering from acid reflux doesn’t guarantee that you’ll experience heartburn.

Some of the causes of heartburn and acid reflux are:

  • Smoking
  • Obesity
  • Slouching
  • Drinking alcohol
  • Eating large meals
  • Weight gain
  • Eating fast
  • Medications like nitrates, antihistamines, theophylline, etc
  • Hiatal hernia
  • Diabetes
  • Pregnancy
  • Eating before sleeping

These are the major causes of acid reflux. Even though it’s not possible to avoid all of them, some of them are easy to avoid, and doing so will save you from another bad day.



Heartburn vs. Acid Reflux: Symptoms

The major differences between heartburn and acid reflux are in the symptoms. As we’ve discussed earlier, heartburn can cause:

  • Soreness of the throat
  • Sharp pain in the chest
  • Acidic taste in the chest

However, heartburn is actually one of the symptoms of acid reflux. Acid reflux can cause the following symptoms:

  • Nausea
  • Bloating
  • Heartburn
  • Sore throat
  • Warm or acidic taste at the throat
  • Throat tightening
  • Abdominal pain
  • Difficulty in swallowing

These are the major symptoms that you will experience if you’re suffering from acid reflux.
