Sarcoidosis
What Are the Symptoms?
Symptoms of sarcoidosis vary, depending on the area of the body involved, and may be mild, moderate, severe, or absent. The first symptoms are often vague and may include fever, weight loss, or joint pain. Shortness of breath or a cough that won't go away are frequently the symptoms that lead a patient to the doctor.
The lungs are usually the first area to be affected by sarcoidosis. In fact, nine 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.
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 make excess doses of vitamin D. This can lead to blood levels of calcium that is too high, high levels of calcium in the urine, and often a problem with 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 as well. Caucasians are more likely to develop a mild form of the disease, while African Americans tend to develop the more chronic, severe form.
