Dry Eyes or Mouth
Experiencing dry eyes or mouth can be more than just a simple discomfort—it can sometimes indicate an immune system disorder. This may occur due to inflammation, autoimmunity, or a dysfunction in the glands that produce tears or saliva.

What are dry eyes or mouth, and how are they connected to the immune system?
Dry eyes occur when your tears aren't able to provide enough lubrication for your eyes. Dry mouth, also known as xerostomia, is a condition characterized by a decreased production of saliva. When related to the immune system, these conditions can be caused by an autoimmune reaction where the body mistakenly targets the moisture-producing glands, resulting in decreased production of tears or saliva.
What immune system disorders can lead to dry eyes or mouth?
Sjögren's syndrome, an autoimmune disease where your immune system attacks the glands that produce tears and saliva, is a common cause of dry eyes and mouth. Other immune-related conditions, such as lupus and rheumatoid arthritis, can also lead to these symptoms. Additionally, certain types of immune-targeting medications can cause dry eyes or mouth.
How are dry eyes or mouth diagnosed when they're due to immune system disorders?
The diagnosis starts with a comprehensive medical history and physical examination. Your doctor may order blood tests to check for signs of autoimmunity. Special tests to measure tear production, called Schirmer's test, and saliva flow may also be performed. In some cases, a small sample of tissue (biopsy) may be taken from the salivary glands.
Why are blood tests important in diagnosing dry eyes or mouth?
Blood tests can reveal the presence of certain autoantibodies, which are produced by the immune system in autoimmune diseases. These tests can provide valuable information about the underlying cause of dry eyes or mouth.
What are some 'red flag' symptoms that might accompany dry eyes or mouth, suggesting a potential severe immune system disorder?
'Red flag' symptoms that might accompany dry eyes or mouth and indicate a serious immune system disorder include severe pain or redness in the eyes, difficulty swallowing, unexplained weight loss, recurrent fevers, or persistent fatigue. If you're experiencing these symptoms along with dry eyes or mouth, it's important to seek medical attention.
Which type of doctor should I consult if I'm experiencing dry eyes or mouth?
If you're experiencing dry eyes or mouth, you should start by consulting your primary care doctor. Depending on your symptoms and the suspected underlying cause, you may be referred to a specialist such as a rheumatologist (autoimmune specialist) or an ophthalmologist (eye specialist).
Can lifestyle factors contribute to dry eyes or mouth in immune system disorders?
Yes, certain lifestyle factors, such as smoking or low fluid intake, can contribute to dry eyes or mouth. Certain environmental conditions like dry or windy climates can also worsen these symptoms.
What lifestyle changes can help manage dry eyes or mouth due to immune system disorders?
Quitting smoking, maintaining adequate hydration, and using a humidifier in dry environments can help manage dry eyes or mouth. Avoiding activities that might strain your eyes, like prolonged screen time, can also be beneficial.
What is the treatment for dry eyes or mouth due to immune system disorders?
Treatment depends on the underlying cause. This might involve artificial tears or saliva substitutes, medications to stimulate tear or saliva production, or immunosuppressive drugs to manage autoimmune conditions. Good oral hygiene is also important in managing dry mouth to prevent dental problems.
Can dry eyes or mouth due to immune system disorders be completely cured?
While the underlying immune system disorder may not always be curable, the associated dry eyes or mouth can often be effectively managed with the right treatment. It's vital to work closely with your healthcare team to manage your symptoms and maintain your quality of life.
Are dry eyes or mouth due to immune system disorders common?
Yes, dry eyes or mouth are quite common symptoms in several immune system disorders. They may occur as the immune system mistakenly targets the glands producing tears or saliva.
