Background
Gastroesophageal reflux disease (GERD) was recognized as a clinical entity in the mid 1930s and now is the most prevalent upper gastrointestinal (GI) disorder in clinical practice. Around the same time, in 1934, Bray suggested a link between gut symptoms and airway disease. Acid-related laryngeal ulcerations and granulomas were first reported by Chery in 1968. Subsequent studies suggested that acid reflux might be a contributory factor in other laryngeal and respiratory conditions. In 1979, Pellegrini and DeMeester were the first to document the link between these airway symptoms and reflux of gastric contents. They also proved that treatment of reflux disease results in elimination of these airway symptoms.
People who suffer from GERD usually have symptoms such as esophageal damage that result from the stomach acid shooting up into the esophagus. The acid can irritate the tissues of the esophagus resulting in a sore throat and persistent coughing. Patients who suffer from laryngopharyngeal reflux, or LPR, are more likely to experience symptoms as a result of stomach acid refluxing into the larynx.

Famous quotes containing the word background:
“I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.”
—Lyndon Baines Johnson (1908–1973)
“Silence is the universal refuge, the sequel to all dull discourses and all foolish acts, a balm to our every chagrin, as welcome after satiety as after disappointment; that background which the painter may not daub, be he master or bungler, and which, however awkward a figure we may have made in the foreground, remains ever our inviolable asylum, where no indignity can assail, no personality can disturb us.”
—Henry David Thoreau (1817–1862)
“... every experience in life enriches one’s background and should teach valuable lessons.”
—Mary Barnett Gilson (1877–?)
