In short, consumption used to be a common term for tuberculosis. This was because it seemed to consume people from within, with a long relentless symptom of "wasting away." According to the World Health Organization, when the disease becomes active, 75% of the cases are pulmonary TB, that is, TB in the lungs. Symptoms include chest pain, coughing up blood, and a productive, prolonged cough for more than three weeks. Systemic symptoms include fever, chills, night sweats, appetite loss, weight loss, pallor, and fatigue.
