Saliva on the pillow: doctor named hidden diseases it signals

Drool on the pillow in the morning — nearly everyone has experienced this. But what many are accustomed to blaming on an uncomfortable sleeping position may in reality turn out to be an alarming signal from the body. Among the possible causes are gastroesophageal reflux disease and even amyotrophic sclerosis.

As reported by TUT.AZ, this warning was issued by Dr. Landon Duyka from the prestigious Cleveland Clinic. His commentary was published by the outlet Infobae.

According to the specialist, the most common culprit is simply one's sleeping position. As soon as a person lies on their side or stomach, gravity does its job: saliva simply flows out of the mouth. However, in a number of cases, far more serious health problems lie behind this phenomenon.

Excessive salivation often accompanies infections and allergic reactions. The common cold, pharyngitis, tonsillitis, sinusitis — all of these conditions cause tissue inflammation and block nasal breathing. The person begins breathing through their mouth, and saliva inevitably leaks out during nighttime hours. A similar effect can be produced by other respiratory infections, including mononucleosis.

Another possible culprit is gastroesophageal reflux disease. With this condition, stomach acid irritates the walls of the esophagus, and the body activates a defense mechanism: it begins to produce saliva in excess to neutralize the acid. The accumulated excess fluid is what ends up on the pillow.

"Additionally, drooling is sometimes associated with neurological diseases. Conditions such as Parkinson's disease, cerebral palsy, or amyotrophic lateral sclerosis can impair the ability to swallow, leading to the accumulation of saliva in the mouth," the doctor warns.

Dental problems should not be dismissed either. Bruxism — involuntary teeth grinding during sleep — as well as bite misalignment prevent the mouth from closing completely, giving saliva a way out. In addition, medical professionals point out that excessive salivation can be a side effect of a number of medications, including certain antibiotics.

Duyka emphasized that in the vast majority of cases, nighttime drooling is completely harmless and resolves on its own. But if it has appeared suddenly, become regular, or is accompanied by other concerning symptoms, putting off a visit to the doctor is strongly inadvisable.
