Sjögren disease is a chronic autoimmune condition in which the immune system attacks moisture-producing glands, particularly the tear and salivary glands. While dryness is the hallmark feature, Sjögren disease can also affect joints, nerves, lungs, kidneys and blood vessels. Because the condition may evolve over time, structured rheumatology supervision is important.
What Is Sjögren Disease?
The most common symptoms include dry eyes (grittiness, burning, light sensitivity) and dry mouth (difficulty swallowing dry food, increased dental decay). Many patients also experience fatigue, joint pain or stiffness, parotid gland swelling, and Raynaud's phenomenon. The disease may occur alone (primary Sjögren disease) or alongside other autoimmune conditions such as lupus or rheumatoid arthritis.
Why Does It Occur?
Sjögren disease develops when immune cells target saliva and tear-producing glands. Common associated antibodies include Anti-Ro (SSA) and Anti-La (SSB), along with a positive ANA. These laboratory findings support diagnosis but must be interpreted alongside clinical symptoms. Specialist assessment ensures accurate differentiation from medication-related dryness or other conditions.
Systemic Involvement
Although dryness is often the first sign, Sjögren disease can involve multiple organ systems:
- Joints: Inflammatory arthritis resembling rheumatoid arthritis
- Nerves: Peripheral neuropathy causing numbness or tingling
- Lungs: Interstitial lung disease in selected patients
- Kidneys: Tubular dysfunction affecting salt and acid balance
- Blood vessels: Vasculitis in more severe cases
There is also a small increased long-term risk of lymphoma, particularly in patients with persistent gland enlargement or certain blood test abnormalities. Regular monitoring is therefore important.
Smoking and Sjögren Disease
Smoking can worsen dryness symptoms and may aggravate gland dysfunction. It also increases the risk of cardiovascular disease and lung involvement — both of which are particularly relevant in autoimmune conditions. Smoking cessation is strongly recommended.
Treatment of Sjögren Disease
Treatment is tailored to severity and organ involvement. Symptom management includes artificial tears, saliva substitutes, good dental care and adequate hydration. If systemic features are present, immune-modulating therapy such as hydroxychloroquine, methotrexate or other immunomodulatory agents may be required. Biologic therapy may be considered in severe systemic disease.
When to Seek Medical Review
Seek prompt assessment if you develop dry eyes and dry mouth, persistent gland swelling, significant joint swelling, unexplained weight loss, new neurological symptoms or breathlessness. Early specialist review allows monitoring and timely treatment adjustment.
Frequently Asked Questions
Is Sjögren disease only dryness?
No. While dryness is common, the disease may affect joints, lungs, kidneys or nerves, and requires regular specialist monitoring.
Does smoking worsen Sjögren disease?
Yes. Smoking can worsen dryness, increase cardiovascular risk and potentially aggravate lung involvement. Stopping smoking is strongly recommended.
Is Sjögren disease serious?
Most cases are mild, but some patients develop systemic complications that require specialist care. Regular monitoring reduces long-term risk.
Does Sjögren disease increase lymphoma risk?
There is a small increased long-term risk in selected patients, particularly those with persistent gland swelling or abnormal blood tests. Regular monitoring helps identify risk early.
Is treatment lifelong?
Management is individualised. Some patients require only symptomatic treatment, while others need immune-modulating therapy with ongoing specialist supervision.
