Sjögren's Syndrome: Beyond Dry Eyes and Dry Mouth

What is Sjögren's Syndrome?
Sjögren's (pronounced SHOW-grins) syndrome is a chronic autoimmune disorder. The immune system primarily targets and destroys the body's moisture-producing glands—specifically the tear glands (lacrimal) and saliva glands.

While it is characterized by profound dryness, it is a systemic disease. In many patients, the autoimmune attack spreads to affect the joints, lungs, kidneys, blood vessels, and nervous system.

Signs & Symptoms

Sjögren's can occur as a primary condition, or as a secondary condition alongside other autoimmune diseases like Rheumatoid Arthritis or Lupus. The two hallmark symptoms are:

• Severe Dry Eyes: Eyes may burn, itch, or feel as though there is sand or grit trapped inside them.
• Severe Dry Mouth: Your mouth may feel like it is full of cotton, making it difficult to swallow dry foods or speak for long periods.

Systemic Symptoms

Beyond the glands, patients often suffer from:

• Profound, debilitating fatigue.
• Joint pain, swelling, and stiffness.
• Swollen salivary glands (particularly behind the jaw and in front of the ears).
• Dry skin, nasal passages, and vaginal dryness.
• A persistent dry cough.

When to See a Doctor

If you experience persistent dry eyes that over-the-counter drops cannot fix, a constantly dry mouth, or difficulty swallowing dry food, you should consult a doctor. Because Sjögren's drastically increases your risk of dental decay and corneal damage, getting a proper diagnosis and prescription management is essential to protecting your eyes and teeth.

Risk Factors & Complications

Sjögren's predominantly affects women (about 9 out of 10 patients are female) and is most frequently diagnosed in people over the age of 40. Co-existing autoimmune diseases are a major risk factor.

Complications of Dryness

• Dental Cavities: Saliva protects the teeth from bacteria. Without it, patients are at a massive risk for severe dental decay and tooth loss.
• Yeast Infections: Increased risk of oral thrush (a fungal infection in the mouth) and vaginal yeast infections.
• Vision Problems: Chronic lack of tears can cause light sensitivity, blurred vision, and permanent corneal ulcerations.

Diagnosis

Sjögren's is difficult to diagnose because its symptoms mimic medication side effects and aging. Doctors use:

• Blood Tests: To check for specific Sjögren's antibodies (SS-A and SS-B) and signs of inflammation.
• Eye Tests: The Schirmer tear test measures the exact quantity of tears your eyes produce using a strip of filter paper.
• Lip Biopsy: A minor surgery to remove a tiny salivary gland from the inside of the lower lip to check for clusters of inflammatory cells.

Treatment & Relief

Treatment focuses on relieving symptoms and suppressing the autoimmune activity if it threatens internal organs.

• Moisture Replacement: Prescription eye drops (like Restasis or Xiidra) reduce eye inflammation, while frequent use of artificial saliva and drinking water helps the mouth.
• Saliva-Stimulating Drugs: Medications like Pilocarpine (Salagen) or Cevimeline (Evoxac) can stimulate the glands to produce more saliva and tears.
• Immunosuppressants: If systemic symptoms (like severe joint pain or lung involvement) occur, doctors may prescribe Hydroxychloroquine (Plaquenil) or stronger drugs like Methotrexate.

Frequently Asked Questions (FAQs)

Can drinking more water cure my dry mouth?

While staying hydrated is critical, drinking water cannot replace the complex enzymes and protective proteins found in natural saliva. You must still practice rigorous dental hygiene and use fluoride treatments or artificial saliva to protect your teeth.

Does Sjögren's syndrome go away?

No, it is a chronic, lifelong condition. However, with proper medical management, symptom relief strategies, and excellent dental and eye care, most patients lead full and active lives.
