Persistent heartburn is a common but frequently underestimated symptom that, when left unmanaged, can indicate ongoing gastro-oesophageal reflux disease (GERD) and lead to progressive damage of the oesophageal lining. A clinical overview published by Medical Daily outlines the relationship between reflux, oesophagitis, and Barrett’s oesophagus, alongside diagnostic and management considerations.
Heartburn arises when stomach contents, including acid and digestive enzymes, flow back into the oesophagus through a weakened or inappropriately relaxed lower oesophageal sphincter. Reflux refers to this backward flow, while GERD describes the chronic condition resulting from frequent or tissue-damaging episodes. Repeated acid exposure inflames the oesophageal mucosa, potentially causing ulceration, scarring, and luminal narrowing over time, a condition termed reflux oesophagitis.
In a subset of patients, prolonged acid and bile exposure causes metaplastic change in the normal squamous epithelium of the lower oesophagus, resulting in Barrett’s oesophagus. This change is clinically significant due to its association with an elevated risk of oesophageal adenocarcinoma. Risk factors for progression include long-standing reflux, older age, central obesity, smoking, and hiatal hernia.
Diagnosis typically begins with a clinical history of symptom frequency and severity. Upper endoscopy allows direct visualisation of inflammation, erosions, ulceration, or metaplastic change. pH monitoring and oesophageal motility testing may be used in selected cases. Oesophagitis frequently resolves with acid suppression and lifestyle modification, though Barrett’s oesophagus generally requires long-term endoscopic surveillance.
Symptoms warranting prompt evaluation include dysphagia, unexplained weight loss, haematemesis, melaena, and persistent chest pain, as these may indicate significant oesophageal injury or malignant change.
