Silent gastroesophageal reflux disease (GERD) is an atypical form of reflux disease in which patients present predominantly with extra-esophageal manifestations rather than classic symptoms such as heartburn or acid regurgitation. In this form, gastric refluxate may reach the upper aerodigestive tract, leading to laryngeal or respiratory symptoms that are frequently misattributed to infectious or allergic conditions. The absence of typical gastrointestinal complaints often results in delayed diagnosis and repeated ineffective treatments. We report the case of a 27-year-old male who presented with acute dry cough and progressive hoarseness without gastrointestinal symptoms. After excluding infectious and allergic etiologies, and noting a poor response to antitussive and bronchodilator therapies, a presumptive clinical diagnosis was established. Recognition of dietary triggers and rapid symptom resolution following a 4-week empirical trial of proton pump inhibitor therapy—along with symptom recurrence upon temporary discontinuation—supported the diagnosis of silent GERD. This case highlights the importance of considering reflux-related etiologies in patients with unexplained cough and laryngeal symptoms to avoid diagnostic delays and unnecessary empirical treatments.
