Sialorrhea, also known as excessive drooling or hypersalivation, is a condition characterized by an excessive production of saliva beyond what is considered normal. It can result in an increased flow of saliva from the mouth, leading to involuntary drooling. Sialorrhea can occur due to various factors, including neurological disorders, medication side effects, dental problems, or other underlying conditions. It can be a source of discomfort, embarrassment, and potential complications such as skin irritation or aspiration. Treatment options depend on the underlying cause and may include medication, behavioral techniques, or surgical interventions to manage or reduce excessive saliva production.
