Silent Reflux

Silent reflux differs from typical heartburn because it may not produce typical acid reflux sensations. LPR is distinct from GERD in that LPR symptoms manifest in the upper airway while GERD symptoms are felt in the stomach and mid-chest. Betaine hydrochloride taken before meals restores stomach acidity and causes the esophageal sphincter to close, stopping reflux. Burning throat syndrome, silent acid reflux, and LPR all refer to the same condition. In LPR, acid damage is concentrated in the throat and voice box rather than the stomach. Silent reflux involves acid regurgitating into the esophagus without classic heartburn symptoms, causing it to go unrecognized. The esophagus and throat lack the mucosal barrier that protects the stomach, so acid reaching those tissues causes direct chemical injury. Silent reflux differs from typical acid reflux in lacking the classic heartburn sensation, causing it to go unrecognized. Acid irritation of esophageal sensory nerves causes the brain to interpret the signals as insufficient oxygen, producing air hunger. Excessive breathing triggered by silent reflux raises blood oxygen but lowers CO2, approaching respiratory alkalosis. Betaine HCl and…
