Dry Mouth can arise from 2 documented medical conditions. Understanding the clinical context helps identify urgent causes early.
Sjögren's Syndrome
Sjögren's syndrome is an autoimmune disease primarily affecting the salivary and lacrimal glands, causing dry eyes (xerophthalmia) and dry mouth (xerostomia). It can be primary or secondary to other autoimmune diseases like RA or lupus.
Primary Biliary Cholangitis
Primary biliary cholangitis is a chronic autoimmune liver disease causing progressive bile duct destruction. Left untreated it leads to liver cirrhosis.
