Laryngopharyngeal Reflux

Laryngopharyngeal RefluxSometimes, harmful gastric acid can come back up from the stomach, through the esophagus and irritate the throat. Unlike normal cases of acid reflux, you may find yourself unable to sleep lying down and experience a frequent cough. Over the next few days, you may notice some additional irritating symptoms such as a sore throat and cough remain. If so, you may have laryangopharyngeal reflux.

What is Laryngopharyngeal Reflux?

Laryngopharyngeal reflux (LPR)is a condition where gastric acid, or stomach acid, travels up the esophagus and into the throat. If left untreated, this condition can damage the throat, voice box, esophagus, and lungs.

Laryngopharyngeal reflux is also known as silent reflux since it does not always cause heartburn like other acid reflux conditions. Anyone can develop laryngopharyngeal reflux including children; however, it is more commonly seen in adults due to certain dietary and lifestyle habits.

What Causes Laryngopharyngeal Reflux?

When we eat, the food travels from the mouth, down the esophagus, and into the stomach. Then, the stomach begins to break down food by producing gastric acid. A muscle known as an esophageal sphincter controls the opening between the esophagus and stomach and works to keep the contents of your stomach from going back up your esophagus.

If the muscle fails to close properly while digesting, it can allow acid to return up the esophagus, into the throat, and in some cases the nasal passageways. The harsh acid can irritate, inflame, and damage soft tissues that are vulnerable to gastric acid causing a chronic cough and additional symptoms associated with Laryngopharyngeal reflux. A weak esophageal sphincter or hiatal hernia may be the cause of the condition.


The most common symptoms experienced in patients with laryngopharyngeal reflux include:

  • Bitter taste in the mouth
  • Blockage of the airway leading to noisy breathing such as wheezing or apnea
  • Changes in voice
  • Chronic cough
  • Difficulty swallowing
  • Excessive throat clearing
  • Hoarseness
  • Post-nasal drip
  • Red, swollen, or irritated voice box (larynx)
  • The sensation of a lump in the throat
  • Sore throat

Though not common in patients diagnosed with laryngopharyngeal reflux, heartburn may occur.

If left untreated, complications may occur such as ulcers on the vocal folds, worsening of respiratory conditions, scarring of throat tissue and voice box, irritation along the throat and esophagus, and lung damage such as pulmonary fibrosis.

How is Laryngopharyngeal Reflux Diagnosed?

Gastric reflux conditions can often be diagnosed by a patient’s symptoms and an examination of the throat. However, Laryngopharyngeal reflux can be difficult to determine and is often diagnosed using one of the following tests:

  • Laryngoscopy, where an endoscope is used to display any damage or irritation along your throat, esophagus, and stomach.
  • Diagnostic imaging, such as X-rays can be used after the patient swallows a special liquid known as barium which can show the movement of food as it passes through the body.
  • An esophageal pH test can also be used to measure and record the amount of acidity within the esophagus. We use a wireless test which is a small capsule placed in the esophagus to wirelessly transmit the data to a recorder.

Treatment Options

Mild cases of laryngopharyngeal reflux do not require medical care and can be managed with lifestyle changes.

Your doctor may recommend prescription medication to reduce and neutralize gastric acid and increase pressure on the sphincter.

In severe or chronic cases, surgery may be needed to create a stronger valve between the esophagus and stomach.
