What is Sarcoidosis?
Sarcoidosis is an inflammatory disease that can affect almost any organ in the body. It causes a person’s immune system, which normally protects the body from infection and disease, overreacts, resulting in damage to the body’s own tissues. The common feature of sarcoidosis is the formation of granulomas, microscopic clumps of inflammatory cells that group together (that look like granules, which is where it gets its name). When too many of these clumps form in an organ they can interfere with how that organ functions.
