Laryngopharyngeal reflux

Laryngopharyngeal Reflux

Laryngopharyngeal reflux (LPR), also known as silent reflux, is a medical condition in which stomach acid flows back into the throat and larynx, or voice box. This can cause irritation and damage to the throat and larynx.

Pronunciation

Laryngopharyngeal reflux is pronounced as la-rin-go-fa-rin-gee-al re-flux.

Etymology

The term "laryngopharyngeal" is derived from the words "laryngo" which refers to the larynx, and "pharyngeal" which refers to the pharynx or throat. "Reflux" comes from the Latin word "refluxus" which means "flowing back".

Symptoms

Common symptoms of LPR include a sensation of a lump in the throat, difficulty swallowing, and a chronic cough. Some people may also experience hoarseness or a sore throat.

Causes

LPR is caused by a dysfunction of the lower esophageal sphincter, a muscle that acts as a valve between the esophagus and stomach. When this muscle does not close properly, it allows stomach acid to flow back into the throat and larynx.

Treatment

Treatment for LPR typically involves lifestyle changes such as avoiding certain foods and drinks that can trigger reflux, losing weight if overweight, and quitting smoking. Medications such as proton pump inhibitors and H2 blockers may also be prescribed to reduce stomach acid production.
