Drooling while sleeping occurs when excess saliva accumulates in the mouth as facial muscles relax, causing fluids to escape unintentionally.
Causes of Drooling While Sleeping
Various factors can lead to this condition, most notably:
- Body Position: Sleeping on the side or stomach allows saliva to pool and leak due to gravity, especially for those who breathe through their mouths.
- Respiratory and Sinus Issues: Common colds, influenza, and seasonal allergies cause nasal congestion, forcing a person to breathe through the mouth.
- Digestive Disorders: Gastroesophageal reflux disease (GERD) can increase the production of excess saliva to soothe esophageal irritation caused by stomach acid; it may also cause swallowing difficulties.
- Neurological Conditions: This may be linked to jaw muscle weakness resulting from a stroke, Parkinson’s disease, multiple sclerosis, or muscular dystrophy.
- Sleep Disorders: Obstructive sleep apnea increases the likelihood of drooling and is typically accompanied by snoring, morning headaches, and daytime sleepiness.
- Other Factors: These include dental problems, a diet rich in citrus fruits, or physiological changes during pregnancy.
Medications That Cause Drooling While Sleeping
This issue may appear as a side effect of certain medical treatments, including:
- Alzheimer’s disease medications.
- Antipsychotic medications.
- Certain types of antibiotics.
How to Treat Drooling While Sleeping
The approach to managing this condition depends on the primary cause:
- Behavioral Adjustments: Sleeping on the back to prevent gravity-led leaking, performing exercises to strengthen jaw muscles, or taking a hot bath before bed to open airways.
- Medical Interventions: A doctor may prescribe “scopolamine” to reduce secretions or suggest a lower jaw device to reduce snoring and drooling.
- Advanced Procedures: In neurological cases, Botox injections into the salivary glands may be used. Surgery to remove the glands remains the final option for severe cases.
Frequently Asked Questions
What causes drooling while sleeping in pregnant women?
Pregnancy contributes to an increase in the amount of saliva produced by the salivary glands, which increases the chances of drooling.
What causes drooling while sleeping in children?
This is normal during the first two years of life (from 18 to 24 months) because infants lack full control over mouth muscles and the swallowing process. It also increases during teething and between 3 and 6 months of age.
What is the treatment for drooling while sleeping?
You can try sleeping on your back, treating sinus infections, using pillows that limit movement at night, or consulting a doctor to evaluate the condition and prescribe appropriate treatment.
When Should You Visit a Doctor?
It is recommended to seek medical advice when warning signs appear, such as:
- Severe difficulty swallowing.
- Temporary pauses in breathing during sleep accompanied by snoring and daytime drowsiness.
- The appearance of neurological symptoms affecting jaw movement or facial muscles.
