# Sjögren's Syndrome
What is it
Sjögren's syndrome is a chronic condition in which the body attacks its own fluid-secreting glands. These are mainly the lacrimal glands (which produce tears) and the salivary glands (which produce saliva). The result is that you produce fewer tears and less saliva, which leads to dry eyes and a dry mouth.
Sjögren's syndrome can be primary (standalone) or secondary (occurring alongside another autoimmune disease such as rheumatoid arthritis or lupus). In primary Sjögren's syndrome, immune cells primarily target the salivary and lacrimal glands. In secondary syndrome, dryness occurs as part of a broader autoimmune disease.
This is a condition that usually begins in adulthood, more often in women than in men. It is not contagious and not hereditary, although genetic factors do play a role in who is susceptible to it.
Causes
The precise cause of Sjögren's syndrome is still not fully understood. What we know is that the body deploys its own immune cells against the salivary and lacrimal glands. This does not happen by chance — usually both genetic susceptibility and environmental factors play a role.
Research suggests that certain viral infections may play a role in its development, although this does not apply to everyone. Hormonal factors also appear to be important: women develop it more often, especially around and after menopause.
If you already have an autoimmune disease, your chance of developing Sjögren's syndrome is greater. But many people with this syndrome have no other known autoimmune disease.
How the disease progresses
Sjögren's syndrome usually progresses slowly. Symptoms begin mildly and may gradually worsen over months or years. Some people notice little change over a long time, while in others it is noticeably progressive.
The disease primarily affects the lacrimal and salivary glands. But because this autoimmune system can affect much more than just those glands, other parts of the body can also slowly be affected: joints, muscles, lungs, kidneys and the nervous system.
The course is not always predictable. Some people have periods when things are calmer, others have more stable symptoms. New complaints can develop as the years go by.
Symptoms by phase
**Early stage**
In the beginning, people usually first notice the dryness. The eyes feel gritty or burning, especially with screen work, wind or in dry rooms. The mouth feels dry, especially in the evening, and you cannot tolerate sweets or sour things as well. Some people feel tired or experience general malaise.
**More advanced**
As the disease progresses, dryness can become more bothersome. Speaking or eating becomes more difficult, teeth can become more sensitive, and oral mucosa problems can develop. Joints can also start to hurt (especially hands, knees, wrists). Many people experience severe fatigue that does not go away with rest.
**Later stage**
In later stages, complications can develop. Lung inflammation (pneumonitis) can develop, causing shortness of breath. Kidney problems can occur. Nerve problems can manifest as tingling or muscle weakness. Some people experience digestive problems.
What it means for daily life
Sjögren's syndrome can significantly interfere with daily life, although this varies from person to person.
**Eyes and mouth**: Many people need to use artificial tears and sugar-free gum. Speaking and eating can become difficult. Restaurant visits, social eating moments and long conversations can be tiring. Sunglasses are sometimes needed due to light sensitivity.
**Fatigue**: For many people, this is the most limiting symptom. You feel exhausted, regardless of how much you sleep. This can limit work, hobbies and social contacts. Some people need to adjust their work or work part-time.
**Joints and muscles**: Pain and stiffness can restrict your freedom of movement. Certain postures or activities can cause discomfort.
**Mental wellbeing**: For some people, it is difficult to live with a chronic disease for which there is no cure. Depression and anxiety occur and deserve attention.
**Medical care**: Many regular check-ups are needed — with the dentist, ophthalmologist and rheumatologist. This requires time and energy.
Outlook
Sjögren's syndrome is a disease that stays with you your whole life, but it is not fatal. Many people can live well with this diagnosis with appropriate care and adjustments.
The disease does not limit life expectancy. However, it is important to be alert to possible complications, especially lung problems and kidney problems, which can be better prevented or detected early.
Many treatments do not aim at cure, but at relieving symptoms and slowing progression. This can help reduce fatigue, manage dryness and prevent complications.
In recent years, more treatment options have become available. Research continues into better understanding of what happens in the body and into more effective treatments. This offers perspective on further improved care in the future.
Many people with Sjögren's syndrome find ways to manage their disease well and maintain a full and meaningful life.
Frequently asked questions
**Can I pass Sjögren's syndrome to my children?**
No, you cannot pass it on directly. However, certain genetic factors that increase your susceptibility can be hereditary. This does not mean your child will definitely get it — environmental factors also play a role. Many children of parents with the syndrome do not get it at all.
**Is there a cure?**
Not at the moment. Sjögren's syndrome is a chronic condition that stays with you your whole life. Treatment is about relieving symptoms and preventing complications, so you can function as well as possible.
**Does it get worse as you get older?**
This is not always the case. In some people the disease stabilizes after a while; in others it progresses more progressively. The rate of progression varies greatly from person to person. Regular check-ups help detect possible changes early.
**Can I exercise and move normally?**
This depends on how you feel and what symptoms you have. Many people tolerate moderate movement well. Some need to be more careful with joint pain. A treatment team can advise what is appropriate for your situation. Many people find that regular, adapted activity helps them maintain energy and muscle strength better.
