Watery saliva can be caused by several factors, often linked to nausea or underlying medical conditions. While saliva is primarily water, changes in its consistency can indicate an issue.
Possible Causes of Watery Saliva
-
Nausea: Often, watery saliva is a symptom of nausea, not a separate condition. The feeling of nausea itself can trigger increased saliva production. [Source: Several articles mention the connection between watery mouth and nausea.]
-
Underlying Neurological Conditions: Neurological problems can affect the salivary glands, resulting in altered saliva consistency.
-
Underlying Physical Conditions Affecting the Mouth: Certain mouth or throat conditions can also lead to changes in saliva.
-
Dehydration: While less likely to cause excessively watery saliva, severe dehydration can alter saliva consistency. [Source: Quora discussion suggests that overly thin saliva might indicate dehydration.]
-
Gastroesophageal Reflux Disease (GERD): GERD can cause water brash, a symptom characterized by a sudden flow of saliva mixed with stomach acid, resulting in a watery mouth with a sour taste. [Source: Cleveland Clinic article on water brash.]
When to Seek Medical Attention
If your watery saliva is accompanied by other symptoms like nausea, persistent discomfort, or changes in your overall health, consult a doctor. They can determine the underlying cause and recommend appropriate treatment. This is particularly important if you suspect a neurological or physical condition may be at play.
