Silent reflux, also known as laryngopharyngeal reflux or “LPR,” is a condition in which stomach acid backs up into the throat and voice box area. It is similar to gastroesophageal reflux disease (GERD) but without the heartburn. While GERD is the cause of much discomfort, silent reflux can be even more serious because its symptoms are less obvious and can go unnoticed for a long time, leading to long-term damage.
Symptoms of Silent Reflux
Silent reflux can cause symptoms such as a persistent cough, hoarseness, frequent throat clearing, difficulty swallowing, and a sensation of a lump in the throat. It can also cause a sore throat, bad breath, and a feeling of postnasal drip. It is important to note that the symptoms of silent reflux can be similar to those of other conditions, such as allergies, asthma, or sinusitis.
Causes of Silent Reflux
The exact causes of silent reflux are not fully understood, but it is believed to be caused by a combination of a weakened lower esophageal sphincter (LES) and an overproduction of acid in the stomach. The LES is responsible for preventing stomach acid from entering the esophagus. When this valve becomes weakened or relaxed, it allows the acid to move up into the throat and voice box area, resulting in the symptoms of silent reflux.
Diagnosing Silent Reflux
Diagnosing silent reflux can be difficult, as the symptoms can be vague and can be attributed to other conditions. However, there are tests that can be done to help diagnose the condition. These tests can include a barium swallow, endoscopy, and pH monitoring. It is important to note that the diagnosis and treatment of silent reflux should be done by a qualified physician.
Treatment of Silent Reflux
The primary treatment for silent reflux is lifestyle modifications, such as avoiding certain foods and beverages that can trigger the symptoms. In addition, medications such as antacids, H2 blockers, and proton pump inhibitors can be used to reduce the amount of acid in the stomach and to prevent the symptoms of silent reflux. Surgery may also be recommended in cases where lifestyle changes and medications are not effective.
