Silent reflux is just like acid reflux except you dont get the symptoms like heartburn or indegestion, you dont know you have it but its there.

It's like regular acid reflux except instead of staying in the esophagus it goes up into your throat. One often doesn't know that they have acid reflux until they go to the doctor with throat problems (sore throat, hoarse voice ect...)

Laryngopharyngeal reflux, sometimes called silent reflux is similar to GERD, but the symptoms are different. At either end of the esophagus there are 2 sphincters, with Laryngopharyngeal reflux, these 2 muscles that keep the contents of the stomach in, are loose, so stomach content backs up into your larnyx, or nose.

Acid reflux is bad at night because gravity is no longer on your side. This is also called silent reflux. The body is laying fairly flat and this allows for the acidity from your stomach to travel up into your chest and throat damaging everything in its path.

The throat is the esophagus. It is not protected from contact with the stomach acid so it is eroded.
