New sound recording device helps doctors study link between cough and reflux

ScienceDaily (2010-10-14) -- Coughing episodes are closely related to gastroesophageal reflux symptoms in patients who experience chronic cough, irrespective of other diagnoses, according to a new study. Gastroesophageal reflux occurs when the acid contents of the stomach back up, or reflux, into the esophagus. This typically produces heartburn, a burning sensation below the sternum where your ribs come together.
