Laryngopharyngeal reflux occurs when muscles in the digestive system do not properly close and stomach acid moves into the upper throat. This triggers inflammation in the throat, which may lead to symptoms such as the feeling of too much mucous in the throat, the feeling that something is stuck in the throat, chronic cough, throat clearing, and voice changes.
Most acid reflux is related to diet and overall health, and can be improved with dietary changes. When lifestyle changes are not enough to control the symptoms of acid reflux, doctors usually prescribe medications to treat the problem. There are instances in which surgery is used to repair the underlying cause of acid reflux as a last resort when lifestyle changes and medications are ineffective.
Acid reflux is rarely serious, but it is extremely unpleasant and interferes with quality of life, and over time, acid can damage the lining of the esophagus.
