Silent reflux, also known as laryngopharyngeal reflux (LPR), is a condition where the acid from the stomach rises up to the throat and voice box. Unlike gastroesophageal reflux disease (GERD), silent reflux does not cause heartburn or indigestion.

This is why it is often referred to as “silent” because it is more difficult to diagnose and detect.

Causes of Silent Reflux

There are several causes of silent reflux. These include:.

Being overweight or obese
Hiatal hernia
Pregnancy
Smoking
Alcohol consumption
Eating large meals or lying down immediately after eating

Symptoms of Silent Reflux

Silent reflux may not cause obvious symptoms, but there are several signs that should not be ignored. These include:.

1. Persistent Sore Throat

If you have a sore throat that lasts for weeks despite trying various remedies, it could be a sign of silent reflux. The throat is more sensitive to acid than the esophagus, so it is typically the first area damaged by reflux.

2. Hoarseness

Hoarseness is a common symptom of silent reflux. The acid can cause inflammation and swelling of the vocal cords, leading to a change in voice, coughing, and difficulty in speaking.

3. Chronic Cough

When acid reflux reaches the upper respiratory tract, it can trigger a chronic cough. If you have a cough that persists for more than eight weeks, it could be a sign of silent reflux.

4. Postnasal Drip

Postnasal drip occurs when excess mucus accumulates at the back of your throat, which causes a sensation of having something stuck in your throat.

This is a common symptom in silent reflux because the acid irritates the throat and causes more mucus production.

5. Difficulty Swallowing

Difficulty swallowing or dysphagia can be a sign of silent reflux. Acid damage to the esophagus can make it difficult to swallow, and the sensation of food getting stuck in the throat may occur.

6. Chronic Throat Clearing

Silent reflux can also cause chronic throat clearing. This is because the acid causes irritation and inflammation in the throat, which triggers the body’s natural reflex to clear the throat.

7. Bad Breath

A persistent bad breath that does not go away with brushing or mouthwash could be a sign of silent reflux. The acid causes irritation and inflammation in the throat, which can lead to an unpleasant odor.

8. Chest Pain

Chest pain can occur in silent reflux, which is often confused with heart disease. The acid can cause discomfort and pain in the chest area, mimicking the symptoms of a heart attack.

9. Nausea

Nausea can be a sign of silent reflux, although it is less common. The acid can cause irritation in the stomach, leading to uncomfortable and sickening sensations.

10. Sleep Disturbances

Silent reflux can disturb sleep patterns because it causes discomfort, coughing, and choking. You may wake up frequently during the night and have difficulty falling back to sleep.

Diagnosis and Treatment

It is essential to diagnose and treat silent reflux promptly to avoid permanent damage to the throat and voice box.

Diagnosis usually involves a physical examination, review of symptoms, and tests such as pH monitoring, laryngoscopy, or a barium swallow test. Treatment typically involves lifestyle changes such as losing weight, quitting smoking, avoiding alcohol and caffeine, and eating smaller meals.

Antacids and proton pump inhibitors (PPIs) may also be prescribed to reduce the acid production in the stomach.

Conclusion

Silent reflux may not be as obvious as GERD, but it can cause significant damage to the throat and voice box if left untreated. If you have persistent symptoms, it is essential to seek medical attention promptly.

Lifestyle changes and medication can alleviate the symptoms and improve the quality of life.
