Symptoms of Heartburn: An Overview
Heartburn is a common gastrointestinal symptom often associated with gastroesophageal reflux disease (GERD). It is characterized by a burning sensation in the chest, typically after eating, which might worsen when lying down or bending over. This article synthesizes research findings on the symptoms of heartburn, highlighting its complexity and the factors influencing its severity.
Common Symptoms of Heartburn
Burning Sensation in the Chest
The hallmark symptom of heartburn is a burning sensation in the chest, which can extend to the throat. This sensation is often described as a discomfort or pain that can last from a few minutes to several hours 123.
Acid Regurgitation
Many individuals with heartburn experience acid regurgitation, where stomach acid flows back into the esophagus, causing a sour or bitter taste in the mouth . This symptom is particularly prevalent in patients with GERD and can be exacerbated by certain foods and beverages.
Dysphagia and Chest Pain
Heartburn can also be accompanied by dysphagia (difficulty swallowing) and chest pain. These symptoms are more common in severe cases and can significantly impact the quality of life 36. In some cases, chest pain associated with heartburn can be severe enough to be mistaken for a heart attack.
Psychological and Lifestyle Factors
Stress and Anxiety
Psychological factors such as stress and anxiety have been shown to exacerbate heartburn symptoms. Studies indicate that major life stressors can significantly increase the severity of heartburn, and anxiety is strongly related to impaired quality of life in affected individuals 16. Depression is also linked to increased heartburn medication use .
Sleep Disturbances
Heartburn is often associated with sleep disturbances, including difficulty initiating and maintaining sleep, nightmares, and hyperhidrosis (excessive sweating) during sleep. These sleep issues are more prevalent in patients with functional dyspepsia (FD) and irritable bowel syndrome (IBS) who also report heartburn .
Age-Related Variations
Erosive Esophagitis in Elderly Patients
The severity of heartburn does not always correlate with the severity of underlying conditions such as erosive esophagitis, especially in elderly patients. Research shows that while the prevalence of severe erosive esophagitis increases with age, older patients often report less severe heartburn symptoms compared to younger patients . This discrepancy suggests that heartburn severity is an unreliable indicator of the severity of erosive disease in older adults.
Functional Heartburn and Non-Erosive Reflux Disease (NERD)
Functional Heartburn
Functional heartburn (FH) is characterized by heartburn symptoms not related to gastroesophageal reflux. Patients with FH do not show evidence of esophagitis or abnormal esophageal acid exposure. The pathophysiology of FH involves disturbed esophageal perception and psychological factors such as anxiety and depression 7910.
Non-Erosive Reflux Disease (NERD)
NERD is the most common form of GERD and is characterized by symptoms arising from gastroesophageal reflux and esophageal hypersensitivity. Unlike FH, NERD involves actual reflux events, but without visible esophageal damage on endoscopy 89.
Conclusion
Heartburn is a multifaceted symptom influenced by various factors, including psychological stress, age, and underlying gastrointestinal conditions. While the burning sensation in the chest and acid regurgitation are the most common symptoms, heartburn can also lead to significant sleep disturbances and is often exacerbated by stress and anxiety. Understanding these associations is crucial for developing personalized treatment strategies and improving the quality of life for individuals suffering from heartburn.

The Effect of Life Stress on Symptoms of Heartburn
Severe, sustained life stress can significantly increase heartburn symptoms and lead to vital exhaustion, potentially affecting esophageal acid exposure, gastric emptying, or stress-induced hypersensitivity.
Heartburn severity underestimates erosive esophagitis severity in elderly patients with gastroesophageal reflux disease.
The severity of heartburn is an unreliable indicator of the severity of erosive esophagitis in elderly patients with gastroesophageal reflux disease.
Heartburn in patients with achalasia.
Patients with achalasia who experience heartburn have lower basal esophageal sphincter pressures than those without heartburn, suggesting achalasia may develop in the setting of underlying gastrooesophageal reflux disease.
Untangling Non-erosive Reflux Disease From Functional Heartburn.
Non-erosive reflux disease (NERD) and functional heartburn are common causes of refractory heartburn, and both can be treated with medical, endoscopic, and surgical approaches.
