== Some suggestions for improvement == 

 A few sections of the article seem to leave room for improvement.  I'll attempt to address them as time permits. Some suggestions: 

 *General Organization -  The article could use some tidying (i.e.  keeping info about treatment in the treatment section and moving the Barrett's esophagus section to pathophysiology) 
 *Diagnosis - this section seems to over-represent the role of imaging studies, endoscopy, etc. in diagnosis. Clearly, mentioning them is warranted, but I don't think it's clear that most of the time, GERD is a clinical diagnosis. 
 *Posture and GERD - section is totally unreferenced...should be verified or removed. 
 *Surgical treatment - needs some info about the problems with Nissen fundoplication. 
 *Drug section - some info about response rates to PPI's and H2 blockers would be helpful. 
 
 Any thoughts?
