Sjögren’s syndrome is an autoimmune disease in which our own body immune system attacks glands that produce moisture. The misdirected immune system leads to inflammation of tissues and dysfunction in glands of the body that are generating tears and saliva.
Sjogren syndrome affects lacrimal glands which produce tears and salivary glands which produce saliva in the mouth. It causes extreme dryness of eyes and mouth.

Causes:
The cause of Sjögren’s syndrome is not known, your immune system mistakenly attacks your own body cells and tissues instead of attacking harmful bacteria and viruses.
It’s very commonly found in some families who have members with other autoimmune problems, such as systemic lupus erythematosus, autoimmune thyroid disease, type I diabetes, etc. women are mostly affected by this autoimmune disease.

Symptoms:
Symptoms of Sjogrens syndrome are different from person to person. The symptoms and signs are extreme Mouth dryness, Swallowing difficulties, Dental decay, Cavities, Gum disease, Mouth sores and swelling, Hoarseness or impaired voice, Abnormality of taste or loss of taste, Dry cough, and Stones and/or infection of the parotid gland inside of the cheeks, Eye dryness, Eye irritation, Less tear production, feeling of a foreign object in the eye, burning sensation in the eye, it can harm the cornea, which is your eye’s clear outer layer.

It can also affect other parts in the body; you may feel dryness in the throat, nose, lips or skin. The glands which are in the face and neck may get swollen. Some women may feel dryness in their vagina.

Some people may have similar symptoms of rheumatoid arthritis such as stiffness in their joints and pain, though they don’t have the disease.

Diagnosis:
Your doctor may diagnose Sjögren’s syndrome after observing dryness of the eyes and mouth, and running tests are done to detect the presence of the condition. One such test is Schirmer’s test, it is done to measure the eye’s ability to wet a slip of paper. Other examinations are done to determine the presence of Sjögren’s syndrome by testing the production of saliva and antibodies, as well as dryness on the surface of the eye.

Blood test: blood tests are done to check the levels of different types of blood cells, to check if you have germ fighting proteins that many with sjogren syndrome people have. Blood tests can also measure the inflammation in the body. To know if you have high amounts of proteins called immunoglubulins, which are part of your infection fighting system.

Imaging tests: These tests are done to find the functioning of salivary glands. Sailogram: A dye is injected into the salivary glands in front of your ears and a special X-ray shows how much saliva flows into your mouth.

Salivary scintigraphy: you will be given a low level radioactive marker and will be positioned under a gamma scintillation camera that detects the radiation and produces an image. This is to see how quickly it arrives in all your salivary glands.

Biopsy: Lip Biopsy is performed to check the presence of clusters of inflammatory cells.
