Silent Reflux
Silent reflux, also known as laryngopharyngeal reflux (LPR) or extraesophageal reflux disease (EERD), is a condition in which stomach acid and other contents of the stomach flow back up into the throat and mouth. People with silent reflux may experience a wide variety of symptoms, including a hoarse or raspy voice, a sore throat, a cough, difficulty swallowing, and a feeling of a lump in the throat.
GERD
Gastroesophageal reflux disease (GERD) is a chronic digestive disorder that occurs when stomach acid or, occasionally, bile flows back into the esophagus. The acidic contents of the stomach irritate the lining of the esophagus, resulting in symptoms such as heartburn, regurgitation, and difficulty swallowing. In some cases, GERD can lead to more serious health consequences, such as narrowing of the esophagus, breathing problems, and an increased risk of cancer.
Differences between Silent Reflux and GERD
The main difference between silent reflux and GERD is the location of the acid reflux. In silent reflux, the acid reaches the throat and mouth, while with GERD, the acid remains in the esophagus. Additionally, the symptoms of silent reflux are usually less severe than those of GERD. For example, while GERD often causes heartburn and difficulty swallowing, silent reflux often causes a hoarse or raspy voice, a sore throat, and a feeling of a lump in the throat.
