Conditions like Gastroesophageal Reflux Disease can stimulate excess saliva production. This is sometimes referred to as “water brash,” where the body produces more saliva in response to stomach acid.
4. Sleep disorders
Certain sleep-related conditions, such as Obstructive Sleep Apnea, may be linked to drooling. People with sleep apnea often breathe through their mouths or experience disrupted sleep patterns, which can contribute to excess saliva.
5. Neurological conditions
In some cases, drooling may be associated with neurological disorders that affect muscle control, such as Parkinson’s disease. These conditions can make it harder to swallow saliva efficiently.
6. Medications or infections
Certain medications—especially those that affect the nervous system—can increase saliva production. Infections involving the throat or tonsils may also make swallowing more difficult, leading to drooling.
