What is Sjögren's syndrome? A patient's guide to the condition

Sjögren's syndrome is an autoimmune disorder where the body's immune system mistakenly attacks its own moisture-producing glands, leading to dryness in areas like the mouth and eyes. This condition can affect anyone but is more common in women, particularly those over 40. Understanding Sjögren's syndrome is important because it can significantly impact daily life and may be associated with other autoimmune diseases.

What is Sjögren's syndrome?

Sjögren's syndrome is an autoimmune condition. In autoimmune disorders, the immune system, which typically protects the body from infections, mistakenly attacks the body's own tissues. In Sjögren's syndrome, the immune system targets glands that produce moisture, such as salivary glands in the mouth and lacrimal glands in the eyes. This results in symptoms like dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca).

Symptoms of Sjögren's syndrome

The most common symptoms of Sjögren's syndrome are dry mouth and dry eyes. However, the condition can also cause:

• Dry skin
• Joint pain
• Swelling in the salivary glands, particularly those behind the jaw and in front of the ears
• Persistent dry cough
• Vaginal dryness
• Fatigue

These symptoms can vary in severity and may fluctuate over time.

How is Sjögren's syndrome diagnosed?

Diagnosing Sjögren's syndrome can be challenging because its symptoms overlap with other conditions. Doctors often use a combination of tests to confirm the diagnosis, including:

• Blood tests: These look for specific antibodies, such as anti-SSA/Ro and anti-SSB/La, which are often present in people with Sjögren's syndrome.
• Schirmer's test: This test measures tear production to assess eye dryness.
• Salivary gland biopsy: A small sample of salivary gland tissue is examined for signs of inflammation.
• Salivary flow rate test: This measures the amount of saliva produced over a certain period.

Managing Sjögren's syndrome

While there is no cure for Sjögren's syndrome, treatments can help manage symptoms and improve quality of life. Common approaches include:

• Artificial tears and saliva substitutes: These can help alleviate dryness.
• Medications: Anti-inflammatory drugs, such as corticosteroids, or immunosuppressive medications can reduce immune system activity.
• Lifestyle adjustments: Staying hydrated, using a humidifier, and avoiding irritants like smoke can also help manage symptoms.

It's important to work closely with healthcare providers to tailor a treatment plan that addresses individual symptoms and needs.

Frequently asked questions

What causes Sjögren's syndrome? The exact cause of Sjögren's syndrome is unknown, but it is thought to involve a combination of genetic and environmental factors.

Can Sjögren's syndrome affect other parts of the body? Yes, while it primarily affects moisture-producing glands, it can also involve other organs, such as the kidneys, liver, lungs, and nervous system.

Is Sjögren's syndrome hereditary? There is no clear hereditary pattern, but having a family member with an autoimmune disease may increase the risk.

Can men get Sjögren's syndrome? Yes, although it is more common in women, men can also develop Sjögren's syndrome.

Is there a cure for Sjögren's syndrome? Currently, there is no cure, but treatments can help manage symptoms and improve quality of life.

When to see a doctor

If you experience persistent dryness in your eyes or mouth, or if you have other symptoms associated with Sjögren's syndrome, consider consulting a healthcare provider. Early diagnosis and management can help prevent complications and improve quality of life. Remember, decisions about your health should always be made in consultation with a healthcare professional.
