Sarcoidosis Starts in the Lungs

Sarcoidosis is a condition that starts in the lungs and may spread to other body organs. The condition is characterized by inflammation. It is believed that it occurs due to an abnormal immune response which results from exposure to an unknown toxin, medication, or pathogen that has entered the body through the airways. The abnormal immune response causes small areas of inflammation, known as granulomas, to occur. There may be stiffening of the lungs, resulting in a reduced capacity of the lungs to hold air. Typically the condition resolves on its own within several years, although some persons may experience symptoms for the rest of their lives. When sarcoidosis affects only the lungs, symptoms such as shortness of breath and a cough may be experienced. Fever, weight loss, red, watery eyes, and small red bumps on the skin are other symptoms of this condition.

Prednisone is a strong anti-inflammatory drug that is sometimes prescribed for sarcoidosis. This medication works by mimicking the effects of hormones produced by the adrenal glands. Persons with sarcoidosis who require prednisone may continue on a low dose of the medication for several years. Serious side effects of prednisone include osteoporosis, cataracts, diabetes, and increased risk of infection.
