What are the causes and symptoms of dry mouth?
Dry mouth, resulting from thickened or reduced saliva flow, can be caused by a number of factors: medications, both prescription and over-the-counter; such systemic diseases as anemia, HIV infection, or diabetes, manifestations of Sjögren’s syndrome (as rheumatoid arthritis, lupus, chronic hardening and thickening of the skin, or chronic and progressive inflammation of skeletal muscles); infections of the salivary glands; blockage of the salivary ducts caused by stones or tumors forming in the ducts through which the saliva passes; dehydration; such medical therapies as local surgery or radiation; secretion reduction normally involved in the aging process; and emotional stress.
