What mental illness is characterized by constantly spitting?

There is no such thing as a mental illness called "always spitting." Frequent spitting may result from oral irritation, bad habits, stomatitis, gastroesophageal reflux disease (GERD), or generalized anxiety disorder. It can be improved through dietary adjustments, habit correction, and medication. If symptoms persist or are accompanied by oral pain or acid reflux, prompt medical attention is recommended.

1. Oral Irritation: Long-term consumption of spicy or acidic foods, smoking, or alcohol use can stimulate the salivary glands to produce excess saliva, leading to frequent spitting. It is advised to switch to a mild, gentle diet, reduce intake of irritants, quit smoking, and limit alcohol consumption to normalize saliva production.

2. Bad Habits: Repeated unconscious spitting may become a conditioned reflex, or children during the tooth-replacement phase may frequently lick their teeth, reinforcing the spitting behavior. It is recommended to consciously correct these behaviors. Parents should guide children by redirecting their attention to gradually eliminate the habit of frequent spitting.

3. Stomatitis: Bacterial or viral infections can cause inflammation of the oral mucosa, increasing saliva secretion and causing symptoms such as redness, swelling, pain, and ulcers in the mouth. Under medical guidance, medications such as compound chlorhexidine mouthwash, oral ulcer powder, and vitamin B2 tablets may be used to relieve symptoms.

4. Gastroesophageal Reflux Disease (GERD): Relaxation of the lower esophageal sphincter allows stomach contents to flow back into the throat and mouth, stimulating increased saliva production, often accompanied by acid regurgitation and discomfort behind the breastbone. Patients may take medications such as omeprazole enteric-coated capsules, domperidone tablets, or hydrotalcite chewable tablets under medical supervision to alleviate symptoms.

5. Generalized Anxiety Disorder: Prolonged excessive anxiety can disrupt autonomic nervous system function, leading to abnormally increased saliva production, along with persistent tension, palpitations, and low mood. Patients may take sertraline tablets, paroxetine tablets, or oryzanol tablets as prescribed to improve symptoms.

Maintain good oral hygiene by brushing teeth morning and night and rinsing after meals. Eat regular, balanced meals and avoid overeating. Stay emotionally balanced, exercise moderately, manage negative emotions promptly, and reduce factors that trigger abnormal saliva production.
