Relating to or concerning consumption, especially the wasting away associated with tuberculosis.
From consumption + -al (suffix meaning 'relating to'). Consumption historically referred to TB because the disease consumes the body from within.
Before antibiotics, 'consumption' was a death sentence—the disease literally consumed you from inside out. The medical term survives in phrases like 'consumptional disease,' a relic of 19th-century medicine.
