Heartburn

Heartburn is a burning sensation felt in the chest, usually behind the breastbone, caused by stomach acid flowing back into the esophagus. It is a common symptom of acid reflux and may occur occasionally or frequently. Heartburn often worsens after eating, when lying down, or bending over, and while it is usually not serious, persistent symptoms may indicate an underlying digestive condition.

Symptoms

The main symptom of heartburn is a burning pain or discomfort in the chest. Other associated symptoms may include:

• Sour or bitter taste in the mouth

• Regurgitation of food or liquid

• Chest discomfort that worsens after meals

• Difficulty swallowing in some cases

• Increased discomfort when lying down or bending
  Symptoms can range from mild to severe and may last from minutes to several hours.

Causes

Heartburn occurs when the lower esophageal sphincter does not close properly, allowing stomach acid to move upward into the esophagus. Common causes include overeating, consuming spicy or fatty foods, chocolate, caffeine, alcohol, and acidic foods. Other causes may include obesity, pregnancy, smoking, hiatal hernia, and certain medications that relax the esophageal sphincter.

Risk Factors

Several factors increase the risk of experiencing heartburn. These include excess body weight, pregnancy, smoking, high intake of trigger foods or beverages, eating large meals, and lying down soon after eating. People with chronic stress or certain medical conditions affecting digestion may also be at higher risk.

Complications

Occasional heartburn is usually harmless, but frequent or untreated heartburn can lead to complications. These may include inflammation of the esophagus, narrowing of the esophagus due to scarring, ulcers, or a condition where esophageal cells change over time. Chronic symptoms may also interfere with sleep and daily activities.

Prevention

Heartburn can often be prevented by making lifestyle and dietary changes. Helpful measures include eating smaller meals, avoiding trigger foods, not lying down immediately after eating, maintaining a healthy weight, and quitting smoking. Elevating the head during sleep and managing stress can also help reduce symptoms and prevent recurrence.
