Drooling while sleeping can be embarrassing, but experts say it's not always a minor issue. Frequent nighttime drooling could be a sign of a more serious health problem, such as sleep apnea, acid reflux, or even neurological conditions like Parkinson's disease. Doctors recommend seeing an ear, nose and throat specialist or sleep specialist if drooling is a persistent problem, as it may require further testing and treatment.

Why it matters

Drooling during sleep is often dismissed as a minor annoyance, but it can actually be an indicator of underlying health issues that require medical attention. Identifying the root cause is important, as conditions like sleep apnea and Parkinson's can have serious consequences if left untreated.

The details

Potential causes of excessive nighttime drooling include sleep apnea, mouth breathing, acid reflux, sinus infections, dental issues, and neurological disorders. Sleep apnea is a particularly dangerous condition that can lead to heart disease, diabetes, and even premature death if not addressed. Doctors recommend an at-home sleep study to determine if sleep apnea is the culprit. Other potential treatments may include addressing nasal blockages, managing acid reflux, or addressing dental problems.

  • Drooling can occur after a heavy meal or when drinking too much the night before.

What they’re saying

“If this is more of a persistent thing — you're waking up every night and your pillow is drenched — we want you to see a doctor, especially if it's recent. It could be a sign of a more serious sleep disorder or even a neurological condition such as Parkinson's.”

— Dr. Landon Duyka, Clinical Assistant Professor of Otolaryngology (CNN)

“If you suspect you might have a blockage due to a deviated septum, enlarged adenoids or the like, it's a good idea to see an ear, nose and throat specialist who can decide if surgery would be helpful.”

— Dr. Neil Hockstein, Founder and Chief Medical Officer of Parallel ENT & Allergy (CNN)

“Improving apnea, improving snoring, making your nose look better, making your jaw look better — it just doesn't come out in the wash that that actually is what's happening.”

— Dr. Brian Rotenberg, Professor of Otolaryngology (CNN)

What’s next

Any concern about drooling should be taken up with an ear, nose and throat doctor, who may recommend a sleep study to determine the underlying cause.

The takeaway

Persistent nighttime drooling is not just an embarrassing annoyance, but can be a sign of a more serious health issue that requires medical attention. Identifying and addressing the root cause, whether it's sleep apnea, acid reflux, or a neurological condition, is crucial for maintaining overall health and wellbeing.
