Osmosis video - Sarcoidosis

Sarcoidosis is a chronic inflammatory disease whereby inflammatory cells called granulomas get abnormally collected in multiple organs in the body, most commonly the lungs, lymph nodes, eyes, skin, and liver. Its causes are not fully understood, it is believed to be caused by an immune reaction continuing after the initial infection or causative antigen is cleared from the body. Symptoms vary depending on which organs are affected, but they may include shortness of breath, cough, fatigue, weight loss, joint pain, vision changes, and skin rashes. Treatment for sarcoidosis depends on the severity and can involve supportive treatment and steroids.
