Abnormal gastric acid can increase the salivation reflex, and some patients with gastroesophageal reflux may have drooling symptoms, accompanied by common symptoms of gastroesophageal reflux disease including acid reflux, heartburn, and chest pain.
4. Parkinson’s disease
In Parkinson’s disease, due to poor swallowing function, saliva is often not swallowed in time. In addition, due to damage to some nerves, saliva secretion also increases, leading to drooling.
5. Cerebral thrombosis
If there is a blockage in the cerebral blood vessels, some of the muscles that control the throat may be dysfunctional, and the patient cannot actively control the muscles while sleeping, causing drooling.
If accompanied by symptoms such as crooked mouth corners, saliva often flowing in one direction, and eyes not closing tightly, it is time to be extremely vigilant.
