Dry mouth can be a sign of Sjögren's Syndrome, particularly when it appears alongside dry eyes, fatigue, joint pain. 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.

Not every case of dry mouth points to Sjögren's Syndrome — many conditions produce overlapping symptoms. A full clinical evaluation is needed to determine the cause.
