What It Is:
GERD occurs when stomach acid flows back into the esophagus, irritating the lining and triggering a host of uncomfortable symptoms.×
Why It Causes Drooling:
Your body’s natural response to acid reflux is to produce more saliva, which acts as a buffer to neutralize the acid. This excess saliva can overflow while you’re lying down, especially if you sleep on your back.
Other Symptoms:
- Heartburn or a sour taste in the mouth
- Regurgitation of food or liquid
- Chronic cough or hoarseness
- Chest pain or throat irritation
What to Do:
Elevate your head while sleeping, avoid heavy meals before bed, and steer clear of spicy, fatty, or acidic foods. If symptoms persist, your doctor may recommend proton pump inhibitors (PPIs) or other medications.
3. Neurological Disorders – When the Brain Can’t Signal Properly
What They Are:
Conditions like Parkinson’s disease, ALS (Lou Gehrig’s disease), cerebral palsy, or stroke can impair the nerves and muscles involved in swallowing.
Why They Cause Drooling:
These disorders can weaken or delay the swallowing reflex, so saliva builds up in the mouth and spills out during sleep — even if you’re producing a normal amount.
Other Symptoms:
- Tremors or muscle stiffness
- Slurred speech
- Difficulty chewing or swallowing (dysphagia)
- Facial weakness or drooping
- Unexplained weight loss
What to Do:
If you notice drooling along with any neurological symptoms, consult a neurologist. Early diagnosis can lead to better management and improved quality of life.
