Sarcoidosis Fund

Sarcoidosis is a condition that develops when groups of cells in your immune system form red and swollen (inflamed) lumps, called granulomas, in various organs in the body. This inflammatory process can be caused by infections or environmental factors. Sarcoidosis can affect any organ. Most often it affects the lungs and lymph nodes in the chest. It causes fatigue and other symptoms depending on what part of the body is impacted. While some individuals can make a full recovery, for others the disease causes permanent scarring (fibrosis) in the lungs or other organs and can lead to life-threatening heart or lung problems.
