Sjögren's syndrome is an autoimmune disorder.
The body’s immune system attacks glands that secrete fluid, such as the tear and saliva glands.
The effects of Sjögren's syndrome can be widespread. Certain glands become inflamed, which reduces the production of tears and saliva, causing the main symptoms of Sjögren's syndrome, which are dry eyes and dry mouth.
In women (who are most commonly affected), the glands that keep the vagina moist can also be affected, leading to vaginal dryness.
What causes Sjögren's syndrome?
Sjögren's syndrome is an autoimmune condition, which means that instead of protecting the body from infection or illness, the immune system reacts abnormally and starts attacking healthy cells and tissue.
In Sjögren's syndrome, the immune system attacks the tear and saliva glands, and other secretory glands throughout the body.
The reasons for this remains unknown, but research suggests that it's triggered by a combination of genetic, environmental and, possibly, hormonal factors.
Some people are thought to be more vulnerable to the syndrome when they're born and that certain events, such an infection, can trigger the problems with the immune system.
