Why was the illness historically referred to as consumption?
Answer
The disease appeared to physically consume the patient from the inside out.
The term consumption gained popularity because it vividly described the observable physical degradation of the sufferer. Patients with the illness often exhibited a profound and relentless decline in health, marked by significant weight loss, muscle wasting, and a fading away of physical substance. This wasting effect created the impression that an internal fire or infection was literally consuming the body's tissues, which perfectly aligned with the visible progression of the disease before modern medical understanding identified the specific bacterial cause.
