What is reflux?
Reflux occurs when stomach juices flow up into the esophagus and possibly the mouth. Reflux may cause irritation of the esophagus, the throat, and even the lungs. When reflux is chronic, it may produce structuring of the esophagus, cancer in the esophagus, reflux laryngitis, etching of the teeth, asthma, bronchitis, and lung abscess. Diagnosis and proper lifelong treatment is necessary to prevent these complications.
