What Is Sjögren Syndrome?
Sjögren syndrome is an autoimmune disorder, a condition in which the body's immune system attacks its own healthy cells and tissues. Sjögren syndrome causes damage to the tear ducts and saliva glands, leading to dryness of the mouth and eyes. It may also cause dryness to the nose, skin or vagina.
Sjögren syndrome occurs predominantly in women. People who have other autoimmune diseases, such as rheumatoid arthritis or lupus, may have an increased risk.
There are two types of Sjögren syndrome:
- Primary: Sjögren syndrome occurs without the presence of another autoimmune disease
- Secondary: Sjögren syndrome occurs in conjunction with another autoimmune disease
