Complications of sarcoidosis. Chronic fatigue syndrome.

Well-recognised complications are pulmonary fibrosis, cor pulmonale, glaucoma, cataract and nephrocalcinosis causing failure of lungs, heart, vision and kidneys. Less well-recognised is the post-sarcoidosis chronic fatigue syndrome. The afflicted join sarcoidosis patients' associations because of their profound symptoms of myalgia, fatigue, sleep reversal and low-spiritedness. The symptoms are out of proportion to the lack of physical signs and the absence of objective evidence of sarcoidosis. Management includes unremitting sympathy and replenishment of essential neurochemicals.
