Recurring Sour Regurgitation, Reflux Esophagitis Is Threatening Your Stomach

The distress signal sent by the stomach is recognized in modern medicine as gastroesophageal reflux disease. Between the stomach and the esophagus sits the lower esophageal sphincter, which acts as a barrier preventing gastric acid from spilling upward. When this sphincter weakens or opens inappropriately, gastric acid and stomach contents reflux into the esophagus, inflaming the esophageal mucosa and causing reflux esophagitis. This condition is not caused solely by excess gastric acid. The autonomic nervous system and the brain-gut axis play significant roles. Excessive stress stimulates the sympathetic nerve and suppresses the parasympathetic nerve, decreasing motility throughout the digestive tract and increasing gastric acid secretion. In addition, the stress hormone cortisol lowers lower esophageal sphincter pressure and heightens esophageal sensory hypersensitivity, causing notable discomfort even with small amounts of reflux. The concept of qi stagnation in Donguibogam closely parallels what modern neuroscience describes as gut-brain axis dysregulation caused by stress. Delayed gastric emptying is another key factor. When the stomach cannot empty food in a timely manner, internal stomach pressure rises, making it far more likely that gastric acid and ingested food will back up into the esophagus. Frequent post-meal fullness or dyspepsia often reflects reduced gastric motility. This corresponds to the observation in Donguibogam that phlegm-fluid obstructs gastrointestinal movement. Emerging research also shows that gut dysbiosis alters digestive motility and the immune response, contributing to the development and aggravation of reflux disease. Repeated reflux damages the esophageal mucosa, and chronic inflammation can advance to Barrett esophagus, a precursor to esophageal cancer. Gastric acid can also irritate the larynx and vocal cords, leading to chronic cough, hoarseness, and a foreign body sensation in throat. In severe instances, it may cause dental erosion or worsen asthma symptoms. It is a condition that extends beyond occasional heartburn. Managing dietary habits, daily routines, and stress is essential to protect stomach health, and addressing these underlying factors alongside medication is important for recovery.
