[GASTROESOPHAGEAL REFLUX DISEASE – A MULTIFACETED DISEASE]

Gastric content reflux to the esophagus is a physiological phenomenon that occasionally occurs after meal. Gastroesophageal reflux disease (GERD) is a state that appears when the quantity of gastric content surpasses its physiological elimination from the esophagus and causes difficulties with or without associated esophageal mucosa damage, as well as alarming symptoms. The symptoms are defined as alarming if they disturb the patient’s well-being and are the reason for a visit to the physician. The prevalence of GERD in the Western world is 10%-20% and is based on the estimation of the heartburn incidence as the leading symptom. The dominant symptoms are heartburn and regurgitation, especially after a heavy meal, and are highly specific for GERD. Extraesophageal reflux disease represents a wide range of symptoms connected to the upper and lower respiratory system, such as cough, laryngitis, asthma, chronic obstructive pulmonary disease, hoarseness, sinusitis-postnasal drip syndrome, otitis media, recurrent pneumonia and laryngeal carcinoma. The following tests are used in the reflux differential diagnosis: esophagogastroscopy, laryngoscopy and 24-hour pH monitoring. Patients suspected to suffer from GERD are initially treated with empirical proton pump inhibitor therapy twice a day for one to two months.
