What causes drooling during sleep in adults?
Disease description:
I always thought only children drool, but I didn't expect adults to drool during sleep as well. I'd like to ask the doctor, why do adults drool while sleeping?

Drooling during sleep in adults, commonly referred to as nocturnal drooling, may have several potential causes:
1. Improper sleeping posture: Sleeping on one's side or stomach may cause saliva to flow out due to the angle of the mouth. Trying a different sleeping position, such as lying on your back, may help reduce drooling.
2. Oral health issues: Conditions such as periodontal disease, dental caries, or oral infections can lead to increased saliva production, causing drooling.
3. Digestive system problems: Gastroesophageal reflux disease (GERD) or excessive salivation may be associated with nighttime drooling.
4. Neurological disorders: Certain neurological conditions such as Parkinson's disease or stroke may affect facial muscle control, leading to drooling.
5. Medication side effects: Some medications may increase saliva production, for example, antidepressants or antipsychotic drugs.
6. Reduced chewing or swallowing movements during sleep: The muscles of the mouth and throat relax during sleep, potentially decreasing the frequency of swallowing and allowing saliva to accumulate and spill out.
If drooling is accompanied by other symptoms or persists as a concern, timely medical consultation is advised.
