If You Drool While Sleeping Often, It Could Be a Sign of These 6 Health Conditions

by

  • 4. Neurological Disorders (Parkinson’s Disease, MS, ALS)

    • Why: These conditions can affect the nerves and muscles responsible for swallowing (dysphagia), causing saliva to pool and leak during sleep.

    • Signs: Tremors, stiffness, balance issues, changes in speech or coordination, progressive weakness.

    5. Sleep Apnea or Obstructive Breathing Issues

    • Why: Breathing through the mouth during sleep—common in sleep apnea—can cause drooling. It’s often a sign of obstructed nasal or throat airways.

    • Signs: Loud snoring, gasping for air at night, daytime fatigue, morning headaches.

    6. Cardiovascular or Neurological Events (Stroke, TIA)

    • Why: A blockage or bleed in the brain can disrupt muscle control, including swallowing and facial muscles. This can lead to one-sided drooling during sleep.

    • Signs: Sudden facial drooping, arm weakness, speech difficulty, confusion, dizziness. This is a medical emergency.
