The Mayo clinic also has good info about Shogren’s Syndrome.
Sjogren’s (SHOW-grins) syndrome is a disorder of your immune system identified by its two most common symptoms — dry eyes and a dry mouth.
Sjogren’s syndrome often accompanies other immune-system disorders, such as rheumatoid arthritis and lupus. In Sjogren’s syndrome, the mucous membranes and moisture-secreting glands of your eyes and mouth are usually affected first — resulting in decreased production of tears and saliva.
Although you can develop Sjogren’s syndrome at any age, most people are older than 40 at the time of diagnosis. The condition is much more common in women. Treatment focuses on relieving symptoms, which often subside with time.
