What is Sarcoidosis and What Does it Affect?

Sarcoidosis is an inflammatory condition in which tiny collections of cells, known as granulomas, grow in certain organs of the body.  The most common areas of these growths are the lungs, lymph nodes, eyes and skin.  These inflamed cells may alter the normal structure and possibly the function of the organ.  

While there is no cure for this condition, about half of all affected will heal with little or moderate treatment.  However, sarcoidosis may last for years and may affect the function of the organs it has targeted.  Symptoms vary with each organ that is targeted, but general symptoms are fatigue, fever, swollen lymph nodes and weight loss. 

Doctors are not sure what causes sarcoidosis, but believe that some people may have a genetic predisposition to develop the disease which may be triggered by dust, chemicals, bacteria or viruses.  Research is ongoing.
