How Does Sarcoidosis Affect the Lungs?
When you breathe in, you inhale air rich in oxygen through your nose or mouth. This oxygen travels from the lungs to the blood, where it is carried to the rest of the body. When you have pulmonary sarcoidosis, your lungs become scarred (pulmonary fibrosis). This scarring can make it hard to take a full breath. The damage can also make it harder for oxygen to pass from the lungs into the blood.
