Heartburn

Heartburn: Symptoms, Causes, Types, Diagnosis, and Treatments

Heartburn is a common digestive complaint that affects millions of people worldwide. Characterized by a burning sensation in the chest, often after eating or at night, heartburn can significantly impact quality of life if left unmanaged. While occasional heart-burn is typically harmless, frequent or chronic episodes may indicate an underlying condition such as gastroesophageal reflux disease (GERD).

In this article, we’ll explore the symptoms, causes, types, diagnosis, and treatment options for heart-burn. Whether you’re dealing with occasional discomfort or ongoing issues, understanding heart-burn can help you manage symptoms more effectively and protect your long-term health.

What is Heartburn?

Heartburn is a symptom rather than a disease itself. It occurs when stomach acid backs up into the esophagus, the tube that carries food from the mouth to the stomach. This acid reflux irritates the lining of the esophagus, leading to a burning sensation in the chest or throat.

Despite its name, heart-burn has nothing to do with the heart. However, the symptoms can be similar to those of heart conditions, making proper diagnosis essential.

Symptoms of Heartburn

The primary symptom of heartburn is a burning sensation in the chest, but it can be accompanied by other discomforts. Common symptoms include:

• Burning pain behind the breastbone (sternum), especially after eating
• Chest pain that may worsen when lying down or bending over
• Regurgitation of food or sour liquid into the mouth
• Bitter or acidic taste in the back of the throat
• Hoarseness or sore throat
• Persistent cough or throat clearing
• Difficulty swallowing (dysphagia)
• Sensation of a lump in the throat

Heart-burn usually occurs after meals, particularly large or fatty ones, and can be exacerbated by certain behaviors or foods.

Causes of Heartburn

Heartburn occurs when the lower esophageal sphincter (LES) — a ring of muscle between the esophagus and stomach — becomes weak or relaxes inappropriately. This allows stomach acid to escape into the esophagus.

Common Causes Include:

1. Dietary Choices:
   • Spicy foods
   • Fatty or fried foods
   • Chocolate
   • Citrus fruits
   • Tomatoes and tomato-based products
   • Garlic and onions
   • Caffeinated beverages
   • Alcohol
   • Carbonated drinks
2. Lifestyle Factors:
   • Overeating or eating late at night
   • Lying down soon after meals
   • Smoking
   • Wearing tight clothing around the abdomen
   • Stress or anxiety
3. Medical Conditions:
   • Gastroesophageal reflux disease (GERD)
   • Hiatal hernia
   • Pregnancy (due to increased pressure on the stomach)
   • Obesity (which increases abdominal pressure)
   • Gastroparesis (delayed stomach emptying)
4. Medications:
   • NSAIDs (e.g., ibuprofen, aspirin)
   • Calcium channel blockers
   • Antidepressants
   • Sedatives
   • Certain antibiotics
   • Hormone therapies

Understanding the root cause of heart-burn is essential for effective management and long-term relief.

Types of Heartburn

Heartburn can vary in frequency and severity, and its classification often depends on these factors.

1. Occasional Heart-burn

This type occurs infrequently, often triggered by dietary indiscretions or lifestyle factors. It usually responds well to over-the-counter antacids or simple lifestyle changes.

2. Chronic or Frequent Heart-burn

Defined as occurring two or more times per week. This may indicate GERD and requires medical evaluation and possibly prescription treatment.

3. Nocturnal Heart-burn

This occurs at night and can disrupt sleep. It may be more severe because lying down makes it easier for acid to travel up the esophagus.

4. Silent Reflux (Laryngopharyngeal Reflux)

This type may not cause classic heart-burn symptoms. Instead, it may cause hoarseness, chronic cough, or throat discomfort. Because it’s less obvious, it is often misdiagnosed.

Diagnosing Heartburn

Clinical Evaluation

Diagnosis begins with a detailed medical history and symptom review. If heart-burn is occasional, no tests may be needed. However, persistent or severe symptoms warrant further investigation.

Diagnostic Tests May Include:

1. Upper Endoscopy (EGD):
   A flexible tube with a camera is used to inspect the esophagus and stomach. It helps detect inflammation, ulcers, or precancerous changes.
2. Esophageal pH Monitoring:
   Measures acid levels in the esophagus over 24 hours. This is the gold standard for diagnosing GERD.
3. Esophageal Manometry:
   Assesses the strength and coordination of esophageal muscles and LES function.
4. Barium Swallow (Esophagram):
   An X-ray test after swallowing a barium solution, which highlights abnormalities in the esophagus.
5. Biopsy:
   Small tissue samples may be taken during endoscopy to check for complications like Barrett’s esophagus.

Early diagnosis is key to preventing complications such as esophagitis, strictures, or Barrett’s esophagus, a precancerous condition.

Treatment of Heartburn

Treatment depends on the severity and frequency of symptoms. Options range from lifestyle modifications to medications and, in rare cases, surgery.

---

Lifestyle and Home Remedies

These should be the first line of defense, especially for mild or occasional heart-burn.

• Eat smaller, more frequent meals
• Avoid trigger foods and beverages
• Don’t lie down immediately after eating (wait 2–3 hours)
• Elevate the head of your bed by 6–8 inches
• Lose excess weight
• Avoid smoking and alcohol
• Wear loose-fitting clothes
• Practice stress-reducing techniques such as yoga or meditation

Medications

1. Antacids

• Examples: Tums, Rolaids, Maalox
• Provide quick, short-term relief by neutralizing stomach acid.
• Not effective for healing an inflamed esophagus.

2. H2 Receptor Blockers

• Examples: Ranitidine (withdrawn in many countries), Famotidine (Pepcid)
• Reduce acid production
• Work within an hour and provide longer relief than antacids.

3. Proton Pump Inhibitors (PPIs)

• Examples: Omeprazole (Prilosec), Esomeprazole (Nexium), Lansoprazole (Prevacid)
• Most effective for frequent heart-burn or GERD.
• Heal the esophagus and control acid for up to 24 hours.
• Long-term use may increase risks of osteoporosis, kidney disease, and vitamin B12 deficiency.

4. Prokinetics

• Examples: Metoclopramide (Reglan)
• Help strengthen the LES and speed up stomach emptying.
• Less commonly used due to side effects.

5. Alginates

• Form a foam barrier that prevents acid from reaching the esophagus.
• Example: Gaviscon

Surgical and Procedural Options

For those who don’t respond to medications or have complications, surgical options may be considered.

1. Nissen Fundoplication

• The upper part of the stomach is wrapped around the LES to strengthen it and prevent reflux.
• Performed laparoscopically.

2. LINX Device

• A ring of magnetic beads is placed around the LES.
• It opens to allow food through and closes to prevent reflux.

3. Endoscopic Treatments

• Newer procedures that use radiofrequency or other methods to tighten the LES.
• Less invasive than surgery, but long-term effectiveness varies.

Complications of Untreated Heartburn

If left untreated, frequent heart-burn can lead to several complications:

• Esophagitis: Inflammation that can cause ulcers or bleeding.
• Esophageal Strictures: Narrowing due to scar tissue, causing difficulty swallowing.
• Barrett’s Esophagus: Precancerous changes in the esophageal lining.
• Esophageal Cancer: A rare but serious complication, particularly adenocarcinoma.
• Chronic Cough, Asthma, or Laryngitis: Especially with silent reflux.

Heartburn During Pregnancy

Heart-burn is common during pregnancy due to hormonal changes and pressure from the growing uterus.

Safe Remedies for Pregnant Women:

• Eat small meals
• Avoid lying down after meals
• Sleep with head elevated
• Use antacids approved by your doctor

Medications such as H2 blockers or PPIs should only be used under medical supervision.

Prevention Tips for Heartburn

• Know your triggers: Keep a food diary
• Avoid overeating
• Maintain a healthy weight
• Quit smoking
• Limit caffeine and alcohol
• Drink water between meals, not during
• Avoid tight clothing around your waist
• Chew gum to stimulate saliva and reduce acid

---

When to See a Doctor

Consult a healthcare provider if:

• Heart-burn occurs more than twice a week
• Symptoms persist despite using OTC medications
• Swallowing becomes difficult or painful
• You experience unintentional weight loss
• There’s vomiting, especially if it contains blood
• There’s black or bloody stools
• Chest pain occurs alongside other symptoms like shortness of breath

Prompt medical attention can help prevent complications and ensure appropriate treatment.
