Can sepsis kill you?

Yes. Sepsis, a type of systemic inflammatory response to infection and infection related toxins, can lead to kidney failure, respiratory failure, heart failure, liver failure, stroke, etc... All leading to death.
Yes. As a general rule of thumb your risk of dying from sepsis is about 20% per each organ system affected. For instance if you have cardiac dysfunction and liver dysfunction from sepsis your risk of dying could be as high as 40%. Each year severe sepsis strikes about 750, 000 americans. It’s been estimated that between 25and 50 percent of these people die!
Yes. Untreated sepsis is always fatal. Once bacteria start multiplying in your blood without your body being able to fight them off, death is inevitable unless we can get antibiotics to them. And it's usually short -- even a few hours.
