Modern science clearly explains the wisdom of Donguibogam in contemporary medical terms. The main culprit behind heartburn, chest pain, and a foreign body sensation in throat is acid reflux, which is diagnosed as gastroesophageal reflux disease. Between our esophagus and stomach lies a gatekeeper muscle called the lower esophageal sphincter. The problem begins when this barrier weakens or opens abnormally often, allowing gastric acid to spill over into the esophagus.
Normal gastric acid has a strong acidity that sterilizes the stomach and aids digestion, but unlike the stomach, it acts as a severe irritant to the esophageal mucosa, which lacks a protective barrier. Repeatedly exposed to gastric acid, the esophagus sustains inflammation and damage, which provokes heartburn, sharp pain, voice changes, chronic cough, and a foreign body sensation in throat.
Complex interactions between the nervous system and the endocrine system are intertwined in this phenomenon. For example, stress affects our autonomic nervous system to increase gastric acid secretion and lower gastrointestinal motility, raising the likelihood that stomach contents will stagnate. In addition, the stress hormone cortisol exacerbates inflammatory reactions and sensitizes esophageal sensory nerves, making one perceive pain more intensely even from small stimuli. At night, saliva secretion decreases, reducing the capacity to neutralize refluxed gastric acid, and the lying position can worsen reflux, making nocturnal symptoms common.
Obesity is also an important cause of reflux esophagitis; excess abdominal fat presses on the stomach, creating an environment where gastric acid easily flows back into the esophagus. Certain foods, such as fatty foods, coffee, chocolate, and carbonated beverages, can relax the lower esophageal sphincter or promote gastric acid secretion, worsening symptoms. In this way, acid reflux goes beyond simple dyspepsia and has settled as a chronic ailment of modern people and a systemic problem that affects our eating habits, lifestyle, stress management capabilities, and even body shape. Rather than merely suppressing symptoms, it is essential to break the links of this vicious cycle through fundamental lifestyle improvements.
