Nighttime Excessive Saliva: Causes & What to Do

Possible causes of excessive saliva production during the night (nocturnal sialorrhea)

* Sleeping on your back. When you sleep on your back, your tongue can fall back and block your airway, which can cause you to produce more saliva.

* Allergies. Allergies, such as hay fever, can cause nasal congestion and post-nasal drip, which can lead to excessive saliva production.

* Medications. Some medications, such as antidepressants, antihistamines, and decongestants, can cause dry mouth as a side effect. This dryness can lead to increased saliva production in an attempt to compensate.

* Medical conditions. Certain medical conditions, such as gastroesophageal reflux disease (GERD), diabetes, and Parkinson's disease, can cause excessive saliva production.

* Infection. Infections, such as the common cold or strep throat, can cause inflammation and swelling in the mouth, which can lead to increased saliva production.

* Smoking. Smoking can irritate the mouth and throat, which can lead to excessive saliva production.

* Alcohol consumption. Alcohol can relax the muscles in the throat, which can allow saliva to pool in the mouth.

If you are experiencing excessive saliva production during the night, it is important to see your doctor to rule out any underlying medical conditions. Your doctor may recommend lifestyle changes, such as sleeping on your side, avoiding allergens and irritants, and drinking plenty of fluids, to help reduce your symptoms. In some cases, medication or surgery may be necessary.
