Silent reflux, also known as laryngopharyngeal reflux (LPR), is a digestive disorder that affects the upper respiratory system.

While classic acid reflux symptoms involve heartburn and indigestion, silent reflux occurs when the stomach acid comes up into the throat, larynx, and nasal passages without causing heartburn. This condition can be challenging to diagnose because its symptoms can resemble those of other conditions, such as allergies and infections. Below are some of the symptoms of silent reflux:.

Sore Throat

A sore throat is one of the most common symptoms of LPR. The acid from the stomach can irritate the throat, resulting in discomfort, pain, and burning sensations. The throat may also feel scratchy and dry, and it may be difficult to talk or swallow.

The soreness in the throat can be accompanied by hoarseness or a change in the voice.

Chronic Cough

A chronic cough is another common symptom of silent reflux. The acid can irritate the tissues in the throat and larynx, causing a persistent cough that lasts for weeks or even months.

The cough may be dry or produce phlegm and can be worse at night or early in the morning. Some people may cough only when they lie down or bend over.

Postnasal Drip

Postnasal drip is a condition in which excess mucus accumulates in the back of the nose and throat, causing a cough, sore throat, and difficulty breathing.

Silent reflux can cause postnasal drip by irritating the tissues in the nasal passages and sinuses, leading to increased mucus production. Postnasal drip can make it difficult to sleep and can cause a persistent cough that lasts for weeks or even months.

Difficulty Swallowing

Difficulty swallowing or dysphagia is a condition in which it becomes challenging to swallow food or drink, which can lead to choking or aspiration.

Silent reflux can cause dysphagia by causing spasms in the muscles of the esophagus, narrowing the opening of the esophagus, or increasing the pressure in the stomach. Some people may also experience a sensation of a lump in the throat or a feeling of food getting stuck in the throat.

Bad Breath

Having bad breath or halitosis is another common symptom of silent reflux. The acid from the stomach can cause a foul-smelling odor in the mouth, which can be difficult to get rid of even with brushing and flossing.

People with LPR may also have a bitter or sour taste in their mouth, especially after eating or drinking acidic foods or drinks.

Ear Pain

Ear pain is a less common symptom of silent reflux, but it can occur in some people. The acid from the stomach can travel up to the middle ear through the Eustachian tube, causing pain, pressure, or a feeling of fullness in the ear.

The ear pain can be accompanied by tinnitus or ringing in the ears or vertigo, which can affect balance.

Nausea and Vomiting

Nausea and vomiting are rare symptoms of silent reflux, but they may occur in some people. The acid from the stomach can irritate the nerves in the throat and stomach, leading to nausea and the urge to vomit.

Some people may also experience regurgitation, which is when the stomach contents come back up into the mouth without warning or effort.

Asthma-Like Symptoms

Silent reflux can also cause asthma-like symptoms, such as wheezing, shortness of breath, and chest tightness.

The acid from the stomach can reach the lungs through the bronchi, causing irritation and inflammation, which can lead to breathing difficulties. People with pre-existing asthma or other respiratory conditions may experience worsened symptoms due to silent reflux.

Difficulty Sleeping

Difficulty sleeping or insomnia is a common symptom of silent reflux, especially in people with chronic cough, postnasal drip, and throat irritation.

The acid from the stomach can cause discomfort and pain, making it difficult to fall asleep or stay asleep. The lack of sleep can lead to fatigue, mood changes, and weakened immune system.

Unexplained Weight Loss

In rare cases, silent reflux can cause unexplained weight loss, which can occur due to a decreased appetite, nausea, vomiting, and difficulty swallowing.

The acid from the stomach can also interfere with the absorption of nutrients from food, leading to malnutrition. Unexplained weight loss should be evaluated by a doctor to rule out other causes.

Conclusion

Silent reflux is a digestive disorder that can affect the upper respiratory system, causing a range of symptoms such as sore throat, chronic cough, postnasal drip, difficulty swallowing, bad breath, ear pain, nausea, asthma-like symptoms, difficulty sleeping, and unexplained weight loss. If you experience any of these symptoms, it’s essential to see a doctor for a proper diagnosis and treatment.
