Frequent salivation during sleep could be a sign of one of these 6 diseases.

• • infections, poorly fitting dentures, misaligned teeth.

     

  • Reason:   Inflammation or discomfort in the mouth can stimulate excessive saliva production and make swallowing difficult during sleep.

  • Signs:   Reddened gums, toothache, bad breath, visible plaque or swelling.

2. Weakness or paralysis of the facial nerve (e.g., Bell’s palsy)

• • Reason:   Weakness or paralysis of one side of the face can impair the ability to close the lips and swallow saliva effectively.

     

  • Signs:   Drooping of one side of the face, difficulty closing one eye, asymmetrical smile, slurred speech.

3. Gastroesophageal reflux disease (GERD)

• Reason:   

  • When stomach acid rises into the esophagus, this can trigger a reflex increase in saliva production as the body tries to neutralize the acid.

  • Symptoms:   Heartburn, sour taste in the mouth, nighttime cough, chest discomfort.

     

    4. Neurological diseases (Parkinson’s disease, MS, ALS)

    • • Reason:   These diseases can affect the nerves and muscles responsible for swallowing (dysphagia), which leads to saliva accumulating and leaking during sleep.
