Lung Problems
Dry mouth can cause lung problems.
For example, aspiration pneumonia can happen when a person breathes in food instead of swallowing it (dry mouth can keep you from swallowing food properly), and the food gets stuck in the lungs. Pneumonia can also develop when bacteria in the mouth migrate into the lungs and cause infection, or when bacteria get into the lungs and coughing doesn't remove them. (Some people with Sjögren's don't produce enough mucus in the lungs to remove bacteria, and others are too weak to be able to cough.) Pneumonia is treated with various antibiotics, depending on the person and the type of infection. It is important to get treatment for pneumonia to prevent lung abscess (a hole in the lung caused by severe infection).
People with Sjögren's also tend to have lung problems caused by inflammation, such as bronchitis (affecting the bronchial tubes), tracheobronchitis (affecting the windpipe and bronchial tubes), and laryngotracheobronchitis (affecting the voice box, windpipe, and bronchial tubes).
Depending on your condition, the doctor may recommend using a humidifier, taking medicines to open the bronchial tubes, or taking corticosteroids to relieve inflammation. Pleurisy is inflammation of the lining of the lungs and is treated with corticosteroids and nonsteroidal antiinflammatory drugs.
