What is Heartburn?

Heartburn, a symptom of Acid Reflux and GERD is mild and easy to treat. The stomach lining is much denser than the lining over the esophagus, so in contact with the stomach acid, the esophagus experiences a stinging sensation over the chest area. This sensation is called Heartburn, and this feeling vanishes in minutes.

Heartburn has nothing to do with our body’s cardiovascular system but is related to gastroenterology. So, it shouldn’t be considered a heart ailment.
In Heartburn, we could feel a sour, bitter, and salty taste over the throat area, along with the pain behind the sternum. This lasts only for a moment and disappears after that.

Heartburn is treatable at home. The symptoms can disappear after consuming Antacids. But recurring Heartburn is serious and can indicate either Acid Reflux or GERD. Obese and diabetic people are more prone to frequent Heartburns than normal people. Smoking is one of the main causes of Heartburn and should be strictly avoided.

In normal individuals, eating deep-fried food and consuming fatty foods may Cause Heartburn. Lying immediately after a meal should be strictly avoided.

What is Acid Reflux?

Acid Reflux is a chronic phenomenon in which stomach acid rises from the stomach to the esophagus. Acid Reflux occurs particularly when the stomach is under pressure. Slouching can also be a problem for Acid Reflux as it implies pressure on the stomach. Another such case is the hiatal hernia, in which the upper part of the stomach moves over the diaphragm.

Some risk factors that cause Acid Reflux are being overweight, consuming crispy, deep-fried food, consuming carbonated beverages, consuming tea and coffee, smoking, etc.

Acid Reflux may also cause bloody vomit, burping, hiccups upon eating spicy food, feeling of nausea, loss of body weight, and respiratory ailments like wheezing.

Antacids and acid blockers can temporarily cure Acid Reflux but not permanently. Changes in lifestyle and food habits, alongside following the physician’s advice, can help cure Acid Reflux.

Upon inspection by a physician, he may ask for either one or multiple of the following tests: Oesophagal manometry, Stomach acid pH monitoring, Endoscopy, and Biopsy. If the underlying cause is not identified, the physician may suggest surgery. The patient is operated on the lower end of his esophagus.

Main Differences Between Heartburn and Acid Reflux

  • Heartburn is a burning sensation behind the sternum, a symptom of Acid Reflux. Acid Reflux is a chronic disease in which the stomach acid reverts along the esophagus, hurting the delicate tissues of the esophagus.
  • Heartburn is even treatable at home and may not require a medical consultation. Acid Reflux requires consultation from a physician, as the effects are severe.
  • Heartburn is a mild disease. Acid reflux is categorized as mild, moderate, severe, and chronic.
  • Heartburn can disappear on its own after a few minutes. But Acid Reflux requires proper treatment.
  • Heartburn can be treated by taking Antacids and Acid inhibitors. Acid Reflux is treated by altering one’s lifestyle under the guidance of a physician.


Heartburn and Acid Reflex are both related to ailments of the Gastrointestinal tract. The GI tract is important since the GI processes the food we eat. Any disorder in the GI must be treated immediately, as the disease begins from a mild symptom like Heartburn, develops into an issue like Acid Reflux, and may end up in Cancer.

Deep-fried and undercooked foods should be avoided. Smoking may cause GI ailments, and being a chain smoker is also dangerous. The symptoms must be identified at the head start and cured immediately.
