Sepsis
Etymology
From Greek “sēpsis” (putrefaction or rotting), from “sēpein” (to make rotten). The name preserves an ancient and now-outdated belief that the condition was the body literally decaying or “blood poisoning.” Modern medicine tells a different story — sepsis is a dysregulated immune response, not rot — so the word is a fossil of a discarded theory still in daily use.
noun · /SEP-sis/
A life-threatening condition in which the body’s response to an infection spirals out of control and begins damaging its own organs.
What it names
A medical emergency people badly misunderstand — the real danger is not the germ itself but the immune system’s overwhelming reaction to it, which can kill within hours.
Example
What began as a small infected cut turned into sepsis, and she spent a week in intensive care.
Related idea
Sepsis is not the infection itself but the body’s runaway response to it — closer in spirit to inflammation gone systemic and destructive. This is why speed matters so much: the enemy killing the patient is, in a sense, their own defenses.
