Sepsis ranges from less to more severe. As sepsis worsens, blood flow to vital organs, such as your brain, heart and kidneys, becomes impaired. Sepsis can also cause blood clots to form in your organs and in your arms, legs, fingers and toes — leading to varying degrees of organ failure and tissue death (gangrene).

Most people recover from mild sepsis, but the mortality rate for septic shock is close to 50 percent. Also, an episode of severe sepsis may place you at higher risk for future infections.
