Symptoms of sarcoidosis vary, depending on which part of your body is affected by the disease. Symptoms may be widespread, or they may involve only one organ system. The lungs are the main target of the disease. The lungs are affected about 88 percent of the time. Most people have few or no breathing problems, but for some, breathing can be a problem.
Skin lesions occur in one third to one half of people with sarcoidosis.
Sarcoidosis can affect the eyes, making it more difficult to see, but it rarely causes blindness. Eye symptoms usually include eye dryness but may also include swelling of the tear gland. Sarcoidosis may also affect the kidneys and sometimes may even end in kidney failure. Sarcoidosis can also cause the heart to beat abnormally. Inflammation of the heart muscle may occur, making the heart lose its ability to pump blood all through the body.
