Millions experience heartburn and the more serious condition gastroesophageal reflux disease (GERD) daily. And research shows that nighttime heartburn affects nearly four out of five of heartburn sufferers -- disturbing sleep and impairing their ability to function the next day.
Laryngopharyngeal reflux (LPR) is similar to another condition -- GERD -- that results from the contents of the stomach backing up (reflux). But the symptoms of LPR are often different than those that are typical of gastroesophageal reflux disease (GERD).
With LPR, you may not have the classic symptoms of GERD, such as a burning sensation in your lower chest (heartburn). That's why it can be difficult to diagnose and why it is sometimes called silent reflux.
