Introduction: What Is Heartburn?
Heartburn is a common digestive symptom that feels like a burning sensation in the chest, typically behind the breastbone. It often occurs after eating and may worsen when lying down or bending over. Despite its name, heartburn has nothing to do with the heart. Instead, it’s caused by acid reflux—when stomach acid backs up into the esophagus.
Occasional heartburn is common and usually manageable with lifestyle changes or over-the-counter remedies. However, frequent or severe episodes may be a sign of an underlying condition like gastroesophageal reflux disease (GERD) and should not be ignored.
Recognizing the Symptoms of Heartburn
Heartburn symptoms can vary in intensity and frequency but generally include a few hallmark sensations that are hard to miss.
Typical Symptoms
- A burning feeling in the chest, usually after eating, that may last from minutes to hours
- Pain that worsens when lying down or bending over, especially after meals
- A sour or acidic taste in the mouth caused by acid backing up into the throat
- A feeling of food “sticking” in the throat or chest
- Throat irritation or a chronic cough, often occurring at night
- Hoarseness or voice changes, especially in the morning
Heartburn often appears within an hour of eating and may be more intense after consuming large meals, fatty foods, or acidic beverages.
Common Causes of Heartburn
Heartburn is caused by acid reflux, which happens when the lower esophageal sphincter (LES)—a muscle that acts like a valve between the stomach and esophagus—relaxes or weakens at the wrong time. This allows stomach contents to escape upward into the esophagus.
Several factors can contribute to this process:
1. Overeating or Eating Too Quickly
Large meals increase pressure in the stomach and can overwhelm the LES, making it easier for acid to escape. Eating too quickly can also lead to swallowing excess air, which may contribute to bloating and reflux.
2. Trigger Foods and Beverages
Certain foods and drinks are known to relax the LES or increase stomach acid production, including:
- Spicy foods
- Citrus fruits and juices
- Chocolate
- Caffeinated drinks
- Alcohol
- Onions and garlic
- Fried or fatty foods
- Carbonated beverages
Avoiding these items can help reduce the frequency of heartburn episodes.
3. Lying Down After Eating
Gravity helps keep stomach acid where it belongs. Lying down or reclining shortly after a meal can increase the chance of acid moving into the esophagus.
4. Excess Weight
Carrying extra weight, especially around the abdomen, puts pressure on the stomach and can force acid into the esophagus. Obesity is a significant risk factor for frequent heartburn and GERD.
5. Pregnancy
Hormonal changes and the growing uterus pressing against the stomach can cause heartburn, especially in the second and third trimesters. While often temporary, it can be pretty uncomfortable.
6. Smoking
Smoking weakens the LES and reduces saliva production, which usually helps neutralize acid. Smokers are more likely to experience frequent or severe heartburn.
7. Certain Medications
Some prescription and over-the-counter medications can relax the LES or irritate the esophagus, such as:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Calcium channel blockers
- Sedatives
- Asthma medications
- Certain antibiotics
Talking to a healthcare provider is essential if heartburn worsens after starting a new medication.
When to Seek Medical Attention
Occasional heartburn is usually not severe and can be managed with diet and lifestyle adjustments. However, recurring or severe heartburn may indicate a more serious condition and should be evaluated by a healthcare provider.
Signs that you should seek medical care include:
- Heartburn occurring more than twice a week
- Difficulty swallowing
- Chest pain not linked to meals
- Persistent coughing or hoarseness
- Weight loss without trying
- Vomiting or regurgitation of food or blood
These symptoms may point to GERD, esophagitis, or precancerous changes like Barrett’s esophagus. Prompt diagnosis and treatment can prevent complications.
Conclusion: Know the Signs and Address the Cause
Heartburn is a common yet overlooked symptom ranging from mild discomfort to a persistent daily life issue. Recognizing the typical signs and understanding what causes heartburn is essential for effective relief and prevention.
Simple changes—such as modifying your diet, eating smaller meals, avoiding late-night snacks, and staying upright after meals—can make a significant difference. For those experiencing frequent or severe symptoms, medical evaluation is key to ruling out underlying conditions and developing a personalized treatment plan.
With the right approach, heartburn can be managed, allowing for a more comfortable and healthy digestive experience.
