Excess saliva at night over the past 5 days...is this a possible symptom of something?

I have also had increased saliva at night causing me to caugh and keep me up most of the night clearing my thraot from what feels like drainage from my nasal passages into the back of my throat making me caugh. I feel like crap!

Thank you for your question.

Excessive saliva is usually temporary and does not raise concern. Since you have persistent excessive saliva, you may want to consult your physician or dentist. It could be an increase of saliva production or a decreased ability to swallow. There are medications that are used to decrease saliva production although, there are side effects, according to the Mayo Clinic.

The Mayo clinic provides the following information for excess saliva production.

Causes of increased saliva production include:
Pregnancy
New dentures
Inflammation of mucous membranes of the mouth (stomatitis)
A side effect of certain medications, such as clozapine, isoproterenol, pilocarpine and reserpine
Damage to the nerves that control the salivary glands

Causes of a decreased ability to swallow or to retain saliva in your mouth include:
Neurological disorders, such as Parkinson's disease or cerebral palsy
Nasal obstruction, such as due to allergies, sinus infection, nasal polyps and enlarged adenoids
Gastroesophageal reflux
Sjogren's syndrome
Bell's palsy

Seeking a professional opinion for the prolonged saliva production would be beneficial. I hope this helps. Let us know the outcome.
