The lungs are usually the first area to be affected by sarcoidosis: 9 of 10 people with sarcoidosis have some type of lung involvement. Pulmonary sarcoidosis can be serious, leading to the formation of scar tissue (fibrosis) in the lungs. This complication can interfere with breathing.

Cystic fibrosis is a disease that changes how your body makes mucus and sweat. It affects how well your lungs, digestive system, and some other body parts work. It’s caused by a flawed gene.
If you have cystic fibrosis, you may have mucus that’s too thick or sweat that’s too salty. If heavy mucus clogs your lungs, it’s hard to breathe. It can also block your pancreas, an organ in your belly, so you can’t digest your food as well. The disease may make you sweat away too much of the salt your...
Other symptoms include skin rashes or red bumps (erythema nodosum) on the legs. In about 20% to 30% of cases, sarcoidosis affects the eyes, causing redness, tearing, or, rarely, more severe complications, such as cataracts, glaucoma, and blindness. Sarcoidosis can also affect the brain and nerves, heart, liver, and various hormone-producing glands.
The granulomas or clumps of cells that characterize sarcoidosis may occasionally be associated with high levels of calcium in the blood and urine. Too much calcium in the urine may lead to kidney stones.
The course of sarcoidosis also varies among individuals. Usually, patients who experience more generalized symptoms, such as weight loss and fatigue, develop a mild form of the disease. Patients suffering from shortness of breath and skin rashes may develop more chronic, severe sarcoidosis. Race also seems to play a role; Caucasians are more likely to develop a mild form of the disease, while African-Americans tend to develop the more chronic, severe form.
