The main symptoms of Sjögren's syndrome are dry eyes and a dry mouth, but it can also cause several other problems.

Each person is affected differently. For some people the condition may just be a bit of a nuisance, while for others it can have a big impact on their daily life.

There are many conditions that can cause similar symptoms. See a GP if you have any symptoms you're worried about.

Signs that you may have dry eyes include:

• burning, stinging or itchy eyes
• a feeling of grit or sand in your eyes
• sore, red and swollen eyelids
• discomfort when looking at lights
• sticky eyelids when you wake up
• blurred vision

These symptoms may be worse when the air is dry, for example, when you're somewhere that's windy, smoky or air conditioned.

Dry eyes can be caused by many conditions besides Sjögren's syndrome.
