Sarcoidosis is a condition in which clusters of inflammatory cells, called granulomas, develop in the body. When these granulomas form in the lungs, they may affect breathing or cause persistent respiratory symptoms. In some patients, sarcoidosis remains stable or improves. In others, ongoing inflammation may require monitoring and treatment.
Because lung involvement can vary, pulmonary follow-up is important. Treatment decisions depend on symptoms, how the lungs are functioning, and whether inflammation appears to be affecting respiratory health.
