Superfluous salivation is not an enjoyable picture. Physicians who deal with acid reflux often call this phenomenon a water brash too. The excessive production of saliva is how our organism gets ready to get rid of some trash stuck in the esophagus. Watering is also the sign of upcoming vomiting. Acid reflux can be defined as a trigger for excessive salivation to achieve an acid balance. This sign is often noticed in people with a vitamin B deficit. All of these factors are important to analyze when trying to diagnose the illness correctly.
