A four-month-old baby produces a lot of saliva and keeps coughing. What should I do?

Patient's question:

No

Doctor's answer:

Persistent drooling is commonly seen in central nervous system disorders, such as congenital brain developmental abnormalities, sequelae of encephalitis or meningitis. This is due to lesions in the brain that impair the function of regulating swallowing saliva. It is recommended to visit a pediatric department for examination to confirm the cause and then proceed with treatment.
