Sarcoidosis is more common in women than in men. In the United States, it occurs more often in blacks than in whites. Sarcoidosis is not contagious. You can't catch sarcoidosis from another person who has the disease. The symptoms of sarcoidosis vary, depending on which part of the body is affected.
Symptoms can involve several parts of the body, or only one.
Although almost any area of the body can be affected, most people have few, if any, symptoms. Less than half of people with sarcoidosis need any treatment. The most common symptoms involve the lungs, skin, eyes and liver. People with sarcoidosis may have a cough or chest pain. Some people have breathing problems, but most people have few or no breathing problems.
