Sjogren’s Syndrome

What is sjogren’s syndrome?

Sjogren’s syndrome (also spelled Sjögren’s syndrome, ICD-10 code M35.0) is a long-term autoimmune disease. Autoimmune means the body’s immune system, which normally fights infections, mistakenly attacks the body’s own healthy tissue. In sjogrens syndrome, the immune system mainly targets the glands that make moisture, especially the tear glands in the eyes and the salivary glands in the mouth. When these glands become inflamed and damaged, they produce less fluid, which leads to the two hallmark problems of the condition: dry eyes and a dry mouth.

Although dryness is the most recognized feature, sjogren’s syndrome is a whole-body (systemic) disease. In many people it also affects the joints, skin, nerves, lungs, kidneys, or digestive system, and it commonly causes fatigue. Doctors describe two main forms:

• Primary sjogren’s syndrome — the condition occurs on its own, without another autoimmune disease.
• Secondary sjogren’s syndrome — the condition develops alongside another autoimmune disease, most often rheumatoid arthritis (an autoimmune disease of the joints) or lupus (an autoimmune disease that can affect many organs).

Sjogren’s syndrome can develop at any age, but it is most often diagnosed in people over 40. Women are affected far more often than men. Because the early signs can be mild and easy to mistake for everyday problems such as tired eyes or medication side effects, many people live with symptoms for years before the condition is recognized.

Symptoms of sjogren’s syndrome

Sjogrens syndrome symptoms vary widely from person to person. Some people have only mild dryness, while others develop symptoms in several organs. The most common symptoms include:

• Dry eyes — a burning, gritty, or sandy feeling, as if something is in the eye; sensitivity to light; blurred vision; and eye redness or irritation.
• Dry mouth — difficulty chewing, swallowing, or speaking; a sticky or cotton-like feeling in the mouth; needing to sip water frequently, especially at night.
• Dental problems — because saliva protects the teeth, reduced saliva often leads to more cavities, gum disease, and mouth infections such as oral thrush (a yeast infection of the mouth).
• Swollen salivary glands — especially the parotid glands, located in front of and below the ears, which may become enlarged or tender.
• Fatigue — persistent, sometimes profound tiredness that rest does not fully relieve; this is one of the most common and disabling complaints.
• Joint pain and stiffness — aching joints and muscles, sometimes with mild swelling.
• Dryness elsewhere — dry skin, dry nasal passages, a dry cough, hoarseness, and vaginal dryness in women, which can cause discomfort during intercourse.

Less common symptoms reflect involvement of other organs. Some people develop skin rashes, numbness or tingling in the hands and feet (a sign of nerve involvement called peripheral neuropathy), inflammation of the lungs causing shortness of breath, kidney problems, or acid reflux and swallowing difficulty. Raynaud’s phenomenon — fingers turning white or blue in the cold — also occurs in some patients.

How symptoms present can differ by type. In secondary sjogren’s syndrome, dryness symptoms often appear against the background of an existing autoimmune disease, so joint symptoms from rheumatoid arthritis, for example, may dominate the picture. In primary sjogren’s syndrome, dryness and fatigue are usually the leading complaints. Early in the disease, symptoms may come and go or be limited to mild eye irritation; over time, dryness often becomes more constant, and gland swelling or organ involvement may appear in some people. Importantly, the severity of dryness does not always match the severity of the underlying disease — some people with significant gland damage feel only mild dryness, and the reverse can also be true.

Causes and risk factors

The exact sjogrens syndrome causes are not fully understood. What is known is that the condition results from an abnormal immune response: white blood cells called lymphocytes infiltrate the moisture-producing glands, cause inflammation, and gradually impair their function. The immune system also produces autoantibodies — proteins that mistakenly target the body’s own tissue — which contribute to the disease and help doctors diagnose it.

Researchers believe sjogren’s syndrome develops through a combination of factors rather than a single cause:

• Genetic predisposition — certain inherited gene variants make some people more likely to develop autoimmune diseases. Sjogren’s syndrome is not directly inherited, but autoimmune conditions can run in families.
• Hormonal factors — the strong predominance in women, particularly around and after menopause, suggests that female hormones such as estrogen play a role.
• Environmental triggers — in genetically susceptible people, a trigger such as a viral infection may set off the abnormal immune response, although no single virus has been proven to cause the disease.

Recognized risk factors include:

• Sex — women are affected roughly nine times more often than men.
• Age — most people are diagnosed after age 40, though younger adults and, rarely, children can develop it.
• Another autoimmune disease — having rheumatoid arthritis, lupus, or another autoimmune condition increases the likelihood of developing secondary sjogren’s syndrome.
• Family history — having close relatives with autoimmune diseases modestly increases risk.

Sjogren’s syndrome is not contagious, and it is not caused by anything a person did or failed to do. Lifestyle factors do not cause the disease, although smoking, dehydration, dry environments, and certain medications (such as some antihistamines and antidepressants) can make dryness symptoms worse.

Diagnosis

Sjogrens syndrome diagnosis can be challenging because dryness and fatigue have many possible causes, including normal aging, medication side effects, and other medical conditions. There is no single test that proves the diagnosis; instead, doctors combine the medical history, a physical examination, and several targeted tests. Diagnosis and long-term care are usually coordinated by a rheumatologist — a physician who specializes in autoimmune and joint diseases — often working with eye specialists (ophthalmologists) and dentists. In hospital settings such as Acibadem, this condition is managed within the Rheumatology Department.

Tests your doctor may use include:

• Blood tests for autoantibodies — the most characteristic are anti-SSA (also called anti-Ro) and anti-SSB (anti-La) antibodies. Doctors may also check antinuclear antibodies (ANA), rheumatoid factor, markers of inflammation, and blood counts. A positive antibody test supports the diagnosis but is not enough on its own, and some people with sjogren’s syndrome have negative antibody tests.
• Eye tests — the Schirmer test measures tear production by placing a small strip of paper under the lower eyelid for a few minutes. An ophthalmologist may also apply special dyes to the eye surface and examine it with a microscope (slit lamp) to look for dryness-related damage to the cornea and conjunctiva.
• Salivary gland tests — doctors can measure how much saliva the mouth produces over a set time (sialometry). Imaging of the salivary glands, such as ultrasound of the glands or, less commonly, specialized scans, can show characteristic changes in gland structure.
• Lip (minor salivary gland) biopsy — in some cases, a small sample of minor salivary glands is taken from the inner surface of the lower lip under local anesthesia. Under the microscope, clusters of immune cells within the glands strongly support the diagnosis. This is often considered the most definitive test when other results are unclear.

Rheumatologists frequently use internationally agreed classification criteria, which combine antibody results, eye tests, saliva measurements, and biopsy findings, to help confirm the condition. Your doctor may also order additional tests — such as chest imaging, kidney function tests, or nerve studies — if symptoms suggest that other organs are involved, and will usually rule out other causes of dryness, including medication effects, prior radiation therapy to the head and neck, and certain infections.

Treatment options

There is currently no cure for sjogren’s syndrome, but sjogrens syndrome treatment can relieve symptoms, protect the eyes and teeth, and manage complications. Treatment is tailored to each person’s symptoms and to which organs are affected. Many people do well with simple measures, while others need medications that act on the immune system.

Watchful waiting and self-care

For mild disease, doctors may recommend regular monitoring combined with practical measures rather than strong medication. These often include drinking water regularly, using a humidifier, avoiding smoke and dry or windy environments, chewing sugar-free gum or sucking sugar-free lozenges to stimulate saliva, and meticulous dental hygiene with fluoride products and frequent dental checkups. Reviewing current medications with a doctor is important, because some drugs worsen dryness.

Treatments for dry eyes

• Artificial tears and lubricating gels or ointments — preservative-free products are often preferred for frequent use.
• Prescription anti-inflammatory eye drops — such as cyclosporine eye drops, which may improve tear production over time in some patients.
• Punctal plugs — a minor in-office procedure in which tiny plugs are placed in the tear drainage ducts to keep natural tears on the eye surface longer. In selected cases, the ducts can be closed more permanently with a small procedure.

Treatments for dry mouth

• Saliva substitutes and moisturizing mouth sprays or gels — for symptom relief.
• Saliva-stimulating medications — prescription drugs such as pilocarpine or cevimeline can increase saliva (and sometimes tear) production in people whose glands still have some function. Side effects such as sweating can occur, so these are used under medical supervision.
• Preventive dental care — fluoride treatments and prompt management of cavities and oral thrush.

Medications for systemic disease

When sjogren’s syndrome causes joint pain, rashes, fatigue, or organ involvement, doctors may prescribe medications that modify the immune response:

• Hydroxychloroquine — an antimalarial drug commonly used in autoimmune diseases; it is often tried for joint pain, rashes, and fatigue.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) — for joint and muscle aches, used cautiously.
• Corticosteroids — steroid medicines that reduce inflammation, generally reserved for flares or significant organ involvement and used at the lowest effective dose.
• Immunosuppressive drugs — medicines such as methotrexate, azathioprine, or mycophenolate may be used when internal organs are affected; in severe cases, biologic drugs such as rituximab (an antibody-based medicine that targets certain immune cells) may be considered.

Surgery has a limited role in sjogren’s syndrome. Apart from minor eye procedures such as punctal plug placement or duct closure, operations are rarely needed; salivary gland surgery is generally reserved for unusual situations, such as removing a gland mass that requires evaluation. Because people with sjogren’s syndrome have a higher-than-average risk of developing lymphoma (a cancer of the lymphatic system) in the salivary glands, any persistent, hard, or rapidly growing gland swelling is investigated carefully. Overall, most people never develop this complication, but regular follow-up allows early detection.

Living with sjogren’s syndrome and outlook

Sjogren’s syndrome is a chronic condition, meaning it typically lasts for life. For most people, however, it is not life-threatening, and life expectancy in primary sjogren’s syndrome is generally similar to that of the general population. The main long-term challenges are usually symptom burden — dryness, fatigue, and pain — and the need for ongoing eye and dental care. A smaller group of patients develops involvement of the lungs, kidneys, or nerves, which requires closer specialist monitoring and stronger treatment.

Practical strategies that many people find helpful include carrying water and eye drops, using a bedside humidifier, wearing wraparound glasses outdoors to shield the eyes from wind, avoiding smoking and secondhand smoke, limiting alcohol and caffeine (which can worsen dryness), pacing daily activities to manage fatigue, and staying physically active within personal limits. Regular dental visits, often every six months or more frequently, help prevent tooth loss. Women experiencing vaginal dryness can discuss lubricants and other options with their doctor.

The course of the disease varies. Some people remain stable for many years with mild symptoms, while others experience gradual progression or flares. Because outcomes differ from person to person, doctors avoid making firm predictions; long-term follow-up with a rheumatology team allows treatment to be adjusted as needs change and helps detect complications early.

Frequently asked questions

What is sjogren’s syndrome in simple terms?

Sjogren’s syndrome is an autoimmune disease in which the immune system attacks the glands that make tears and saliva, causing dry eyes and a dry mouth. It can also cause fatigue, joint pain, and, in some people, problems in other organs. It is a long-term condition that is managed rather than cured, most often by a rheumatologist working with eye doctors and dentists.

Can sjogren’s syndrome be cured or go away on its own?

There is currently no cure for sjogren’s syndrome, and it does not usually go away on its own. However, symptoms can often be controlled well with moisture-replacing products, medications, and self-care, and many people maintain a good quality of life. Symptom intensity can fluctuate over time, with better and worse periods, which is why ongoing medical follow-up is recommended.

How serious is sjogren’s syndrome?

For most people, sjogren’s syndrome is a manageable condition whose main effects are dryness, fatigue, and discomfort rather than danger to life. A minority of patients develop involvement of internal organs such as the lungs, kidneys, or nerves, which requires closer treatment, and there is a modestly increased long-term risk of lymphoma, a cancer of the lymphatic system. Regular checkups help detect and manage these less common problems early.

What are the first symptoms of sjogren’s syndrome?

Early sjogrens syndrome symptoms are often subtle: a gritty or burning feeling in the eyes, needing more water when eating dry foods, waking at night with a dry mouth, or unexplained fatigue and joint aches. Because these complaints have many possible causes, the condition is frequently overlooked at first. If dryness is persistent and affects daily life, it is reasonable to ask a doctor whether an autoimmune cause should be considered.

How is sjogren’s syndrome diagnosed?

Doctors confirm the diagnosis by combining several findings: blood tests for autoantibodies such as anti-SSA (anti-Ro) and anti-SSB (anti-La), eye tests that measure tear production and check for surface damage, measurements or imaging of the salivary glands, and sometimes a small biopsy of minor salivary glands from the inner lip. No single test is definitive on its own, so specialists often apply internationally agreed criteria to reach a diagnosis.

What is the difference between primary and secondary sjogren’s syndrome?

Primary sjogren’s syndrome occurs on its own, without another autoimmune disease. Secondary sjogren’s syndrome occurs together with another autoimmune condition, most commonly rheumatoid arthritis or lupus. The dryness symptoms are similar in both forms, but in secondary disease the treatment plan also has to address the accompanying condition, so care is usually coordinated by a rheumatologist.

Does sjogren’s syndrome affect life expectancy?

In most cases, life expectancy for people with primary sjogren’s syndrome is similar to that of the general population. Outcomes can be less favorable when major organs are significantly involved or when complications such as lymphoma develop, but these situations affect a minority of patients. Regular monitoring allows doctors to identify and treat complications early, which supports a better long-term outlook.

When to see a doctor

See a doctor if you have persistent dry eyes or dry mouth lasting more than a few weeks, especially when combined with fatigue, joint pain, or swollen glands near the jaw. Early evaluation helps protect your eyes and teeth and allows treatment to start before complications develop. Seek medical attention promptly if you notice any of the following warning signs:

• A hard, persistent, or rapidly enlarging lump in a salivary gland, the neck, or under the jaw.
• Eye pain, sudden vision changes, or severe light sensitivity, which may indicate damage to the eye surface.
• New shortness of breath or a persistent dry cough, which may suggest lung involvement.
• Numbness, tingling, or weakness in the hands, feet, or face, which may indicate nerve involvement.
• Unexplained fever, night sweats, or significant unintended weight loss.
• Swelling of the legs, changes in urination, or blood in the urine, which may point to kidney problems.
• Severe difficulty swallowing or inability to eat and drink normally.

If you have already been diagnosed with sjogren’s syndrome, keep your scheduled follow-up visits even when you feel well, and report any new or changing symptoms to your care team so your treatment can be adjusted in good time.
