Some info for you...

There are two sphincter muscles located in the esophagus: The lower esophageal sphincter (LES) and the upper esophageal sphincter (UES). When the lower esophageal sphincter is not functioning properly, there is a back flow of stomach acid into the esophagus. If this happens two or more times a week, it can be a sign of gastroesophageal reflux disease, or GERD.
But what happens when the upper esophageal sphincter doesn't function correctly either?

As with the lower esophageal sphincter, if the upper esophageal sphincter doesn't function properly, acid that has back flowed into the esophagus is allowed into the throat and voice box. When this happens, it's called Laryngopharyngeal Reflux, or LPR.

Can you suffer from LPR without experiencing any heartburn or other GERD symptoms? Yes! Many people with LPR do not have symptoms of heartburn. Why? In order for refluxed acid to cause heartburn, it has to stay in the esophagus long enough to cause irritation. Also, the esophagus isn't as sensitive to irritation as the throat is. Therefore, if the acid passes quickly through the esophagus but pools in the throat, heartburn symptoms will not occur but LPR symptoms will.
