waterbrash
Last reviewed 01/2018
Waterbrash is the symptom of tasting acid regurgitated from the stomach; this is a characteristic bitter taste.
This may be a feature of oesophageal reflux or duodenal ulceration.
The combinatin of waterbrash with retrosternal pain - heartburn - is more suggestive of oesophageal reflux rather than a duodenal ulcer.
