A superfluity of saliva is not generally a cause for alarm. Diet can affect how much saliva the salivary glands create, meaning that an increase in saliva could simply indicate the body is adjusting to changes in diet, states WebMD. However, excess saliva can indicate an underlying health concern.
WebMD explains that the salivary glands produce more saliva in order to compensate for the consumption of spicy foods. The taste buds react to contact with pungent foods by creating more saliva. Therefore, if a person is having to constantly swallow because of excess saliva in the mouth, eating milder foods could be all that is needed to solve the issue.
Extra saliva may be an indication of a health condition requiring treatment or a side effect of a particular medication, states WebMD. Too much saliva is often a side effect of such conditions as Bell's palsy, macroglossia, poisoning or stroke. Medications that have been known to increase saliva secretion are Klonopin (a seizure-management medication), Clozaril (a drug used to manage Schizophrenia) and Salagen (often used during radiation treatment).
Excess saliva can be treated in a number of ways, states WebMD. Depending on the reason for the increase, treatment can come in the form of surgery, Botox shots or doctor-prescribed medication. Discussing the reason for excess saliva with a physician is the best way to determine which treatment is best for the individual.
