Definition of Reflux disease, gastroesophageal (GERD)
Reflux disease, gastroesophageal (GERD) definition - medical term
The stomach contents regurgitate and back up (reflux) into the esophagus The food
in the stomach is
partially digested by stomach acid and enzymes. Normally, the
partially digested acid
content in the stomach is delivered by the stomach muscle down into
the small intestine
for further digestion. With esophageal reflux, stomach acid content
refluxes back up into
the esophagus, occasionally reaching the breathing passages, causing
inflammation and
damage to the esophagus, as well as to the lung and larynx (the voice
box).
10% of
patients with GERD develop Barrett's esophagus, a risk factor
for cancer of the esophagus. For more
