Gastric contents (acid and pepsin) directly irritate the sensitive mucosa of the upper aerodigestive tract. While the esophagus has protective mechanisms against acid, the laryngeal and pharyngeal tissues are highly susceptible; even minimal reflux episodes can cause significant inflammation. Indirect Reflex Mechanism:
To understand LPR physiology, it's essential to review the anatomy of the upper digestive tract. The esophagus, pharynx, and larynx are all connected, and play critical roles in swallowing, breathing, and digestion. lpr physiology pdf
Diagnosis of LPR typically involves a combination of: Gastric contents (acid and pepsin) directly irritate the
Laryngopharyngeal reflux occurs when stomach acid flows back up into the pharynx and larynx, causing inflammation and irritation. This can lead to a range of symptoms, including: The esophagus, pharynx, and larynx are all connected,
: Conditions like hiatal hernias or increased abdominal pressure can overwhelm the body's natural barriers against reflux . Management & Treatment Protocol
