The Basics
Sjögren's syndrome (pronounced SHOW-grins) is a long-term autoimmune disease in which the body's immune system mistakenly attacks its own moisture-producing glands. It can occur on its own (primary Sjögren's) or alongside other autoimmune conditions like lupus or rheumatoid arthritis (secondary Sjögren's).
- It affects an estimated 4 million people in the US alone.
- About 9 out of 10 people with Sjögren's are women.
- It can develop at any age, though most diagnoses happen in middle adulthood.
