Water brash a colloquialism for hypersalivation?[edit]

I looked up a few definitions of 'water brash', and I feel it is not a colloquial ism for hypersalivation, which is specifically increased output from the salivary glands. Water brash sounds more akin to acid reflux .Matthew Ferguson 57 (talk) 09:52, 8 November 2014 (UTC)[reply]

You are right, Matthew. Water brash is where a small amount of stomach acid regurgitates up to the back of the throat. Axl ¤ [Talk] 11:42, 8 November 2014 (UTC)[reply]

My impression agrees precisely with Axl; imagine my surprise as I looked for reliable sources when I came across this: PMID 3678754. This suggests that, at least 25 years ago, it was the salivary response to acid reflux that was called water brash. I do think that current sources will bear out the definition Axl describes - and I'm looking - but historically it sounds like it was more complicated. -- Scray (talk) 14:43, 8 November 2014 (UTC)[reply]

As I look further (e.g. PMID 15681902) the meaning does seem to be sialorrhea (increased salivation) specifically in the context of acid reflux. -- Scray (talk) 14:47, 8 November 2014 (UTC)[reply]

From Sleisenger and Fordtran's Gastrointestinal and Liver Disease edited by Mark Feldman (9th edition, 2010, Saunders, ISBN 978-1-4160-6189-2), Chapter 43 "Gastroesophageal Reflux Disease" by Mark Feldman, Lawrence S. Friedman, and Lawrence J. Brandt, pages 705-726: "Finally, the esophagosalivary reflex is impaired in patients with reflux esophagitis and individuals with strictures.⁷⁷ This is a vasovagal reflex demonstrated by perfusing acid into the esophagus, which stimulates salivation. This reflex explains the symptoms of water brash (copious salivation) observed in some reflux patients." and ref 77 is PMID 6873607. So, in answer to your question: "water brash" not a colloquialism but is an accepted medical term for hypersalivation stimulated by acid reflux through a vasovagal reflex loop. Hope this helps. -- Scray (talk) 15:20, 8 November 2014 (UTC)[reply]

Ah, thank you for correcting me and pointing that out, Scray. Axl ¤ [Talk] 22:45, 8 November 2014 (UTC)[reply]

I have reverted the recent edit [1] in question. Actually, the article already seems to have a source defining water brash. Matthew Ferguson 57 (talk) 23:16, 17 November 2014 (UTC)[reply]
