Laryngopharyngeal Reflux (LPR) Symptoms

LPR is a term used to describe a variety of throat symptoms caused by Gastro-oesophageal reflux disease (GERD). It is thought that there as many people suffering with LPR symptoms as more “classical” oesophageal symptoms such as heartburn and regurgitation. Although both throat and oesophageal symptoms can occur together, often patients describe only throat symptoms. Some may complain of a single symptom, such as weakness or change of the voice (dysphonia). The precise mechanism by which reflux from the oesophagus into the throat causes symptoms may differ between patients, which is why, for instance, standard reflux treatments such as anti-acid tablets often do not work in patients with LPR symptoms.

Also, remember that the throat is at a crossroads between the sinuses/mouth, the oesophagus/stomach and the airways/lungs. So, symptoms in the throat may originate in any of these anatomical sites as well as in the pharynx/larynx directly.

Symptoms of LPR

LPR symptoms;

  • Sore throat; sometimes persistent, sometimes worse in the morning.
  • Voice problems: people can report huskiness or weakness of the voice and singers difficulty hitting the right notes.
  • Cough; can occur at night or after eating. Sometimes can respond to anti-acids but if it doesn’t that doesn’t mean it’s not caused by reflux as it may be non-acidic reflux.
  • Throat clearing/mucous and post-nasal drip: Can often be the most troubling and patients often report that their partners complain about this. They describe a constant feeling of mucous in the throat and having to clear this, which can then lead to a sore throat.
  • Lump in the throat; known as Globus
  • Sinus problems; often patients will have been diagnosed with sinus problems or chronic sinusitis, and even have undergone surgery in the past.
  • Bad breath / Halitosis
  • Nasty taste/tingling lips
  • Dental Erosion; when due to acid reflux, this is particularly prominent on the back of teeth.

What causes LPR and how is LPR diagnosed?

Throat symptoms can have multiple causes and it can be difficult to identify their exact cause. For instance throat clearing can be caused by reflux, a post-nasal drip secondary to allergies or sinusitis, vocal cord abnormalities, medications and can even be habitual. It’s likely that LPR can be caused by different problems and may well be more complex than simple GERD.

True LPR, caused by conditions of the gastro-intestinal tract, can include GERD, SIBO, poor gastric emptying and other conditions.

LPR can be diagnosed through a range of tests, and often requires a number of methods to gain an accurate diagnosis. These often include laryngoscopy, pH/impedance monitoring, gastroscopy and others.

What are the treatments for Laryngopharyngeal Reflux (LPR)?

The treatment of LPR is dependent upon identifying the cause. It’s not uncommon for patients to be given a diagnosis of LPR and treated on this basis with little benefit. Because so much remains unknown about LPR and the tests required to make the right diagnosis are not generally available, people often find themselves in what we call a “Cycle of Frustration”, often seeing multiple doctors without reaching resolution.
