President Obama reportedly had a mysterious sore throat for weeks, but now the diagnosis is in: acid reflux into the throat, also called airway reflux or LPR (laryngopharyngeal reflux). This puts the president in good company. Since 1975, the occurrence of reflux has increased 400 percent(almost one in five Americans now suffers from airway reflux), and reflux-related esophageal cancer has increased more than 500 percent to become the most rapidly increasing cancer in the United States.
