Sjogren's syndrome is an autoimmune disease. This means that your immune system attacks parts of your own body by mistake. In Sjogren's syndrome, it attacks the glands that make tears and saliva. This causes a dry mouth and dry eyes. You may have dryness in other places that need moisture, such as your nose, throat, and skin. Sjogren's can also affect other parts of the body, including your joints, lungs, kidneys, blood vessels, digestive organs, and nerves.

Most people with Sjogren's syndrome are women. It usually starts after age 40. It is sometimes linked to other diseases such as rheumatoid arthritis and lupus.

To make a diagnosis, doctors may use a medical history, physical exam, certain eye and mouth tests, blood tests, and biopsies.

Treatment focuses on relieving symptoms. It can differ for each person; it depends on what parts of the body are affected. It may include artificial tears for dye eyes and sucking on sugar-free candy or drinking water often for a dry mouth. Medicines may help with severe symptoms.
