Heartburn: Symptoms, Causes, Treatment, and Prevention

Heartburn is a common condition that affects millions of people worldwide. It is characterized by a burning sensation in the chest, usually after eating or lying down. While it can be uncomfortable, heartburn is generally not a cause for concern. However, frequent or severe heartburn may indicate a more serious underlying condition.

Heartburn: What is it?

Heartburn is a burning sensation in the chest that occurs when stomach acid backs up into the esophagus. It is often described as a feeling of burning or warmth that moves up from the stomach to the chest and throat. The pain can be intense and may be accompanied by other symptoms such as regurgitation, nausea, and bloating.

Symptoms of Heartburn

Heartburn is usually characterized by a burning sensation in the chest, but it can also cause other symptoms, including:

  • A feeling of fullness in the stomach
  • Regurgitation of food or liquid
  • Sour or bitter taste in the mouth
  • Nausea
  • Bloating
  • Burping

If you experience these symptoms frequently or they interfere with your daily life, you should speak to your doctor.

Causes of Heartburn

Heartburn occurs when the lower esophageal sphincter (LES) fails to close properly, allowing stomach acid to back up into the esophagus. The LES is a muscular ring that acts as a barrier between the stomach and the esophagus. When it doesn’t function properly, stomach acid can flow back up into the esophagus, causing heartburn.

Some common causes of heartburn include:

  • Eating large meals or eating too quickly
  • Eating high-fat or spicy foods
  • Drinking alcohol or caffeine
  • Smoking
  • Obesity
  • Pregnancy
  • Hiatal hernia
  • Certain medications, such as aspirin or ibuprofen

Heartburn Triggers

Certain foods and drinks can trigger heartburn, including:

  • Citrus fruits and juices
  • Spicy foods
  • Tomatoes and tomato-based products
  • Chocolate
  • Coffee and other caffeinated beverages
  • Carbonated beverages
  • Alcohol

Heartburn Relief

If you experience heartburn infrequently, there are several over-the-counter remedies you can try, including:

  • Antacids: These neutralize stomach acid and provide fast relief.
  • H2 blockers: These reduce the amount of acid the stomach produces, providing longer-lasting relief.
  • Proton pump inhibitors (PPIs): These also reduce the amount of acid the stomach produces and are often used for more severe cases of heartburn.

Heartburn Prevention

There are several lifestyle changes you can make to prevent heartburn, including:

  • Eating smaller, more frequent meals
  • Avoiding trigger foods and drinks
  • Eating slowly and chewing your food thoroughly
  • Losing weight if you are overweight
  • Quitting smoking
  • Avoiding lying down for at least two hours after eating
  • Elevating the head of your bed by 6-8 inches to prevent acid from flowing back into the esophagus


How long does heartburn last?

Heartburn can last anywhere from a few minutes to several hours, depending on the severity and cause of the condition.

Is heartburn a symptom of a heart attack?

While heartburn can cause chest pain, it is not a symptom of a heart attack. However, if you experience chest pain or discomfort, you should seek medical attention immediately to rule out a more serious condition.

Is heartburn a sign of GERD?

Yes, frequent heartburn can be a sign of gastroesophageal reflux disease (GERD), a more serious condition that can cause damage to the esophagus if left untreated.

Can heartburn be a sign of cancer?

While heartburn itself is not a sign of cancer, persistent heartburn or GERD symptoms can be a risk factor for esophageal cancer. If you experience frequent or severe heartburn, it is important to speak to your doctor.

Can heartburn be cured?

While there is no cure for heartburn, it can be managed with lifestyle changes and medications. If you experience frequent or severe heartburn, speak to your doctor about the best treatment options for you.


Heartburn is a common condition that can be uncomfortable, but it is generally not a cause for concern. However, if you experience frequent or severe heartburn, it is important to speak to your doctor to rule out any underlying conditions. By making lifestyle changes and using over-the-counter or prescription medications, you can manage your heartburn symptoms and prevent them from interfering with your daily life.
