Sepsis occurs when your immune system has a dangerous reaction to an infection. It causes extensive inflammation throughout your body that can lead to tissue damage, organ failure and even death. Many different kinds of infections can trigger sepsis, which is a medical emergency. The quicker you receive treatment, the better your outcome will be.

What is sepsis?
Sepsis is a life-threatening medical emergency caused by your body’s overwhelming response to an infection. Without urgent treatment, it can lead to tissue damage, organ failure and death.

Sepsis definition
Sepsis is your body’s extreme reaction to an infection. When you have an infection, your immune system works to try to fight it. But sometimes your immune system stops fighting the infection and starts damaging your normal tissues and organs, leading to widespread inflammation throughout your body.

At the same time, an abnormal chain reaction in your clotting system can cause blood clots to form in your blood vessels. This reduces blood flow to the different organs of your body and can cause significant damage or even failure.

What are the three stages of sepsis?
Healthcare providers used to organize sepsis into three stages: sepsis, severe sepsis and septic shock. Now, they identify the condition on a more fluid scale. This scale ranges from infection and bacteremia (bacteria in your bloodstream) to sepsis and septic shock, which can lead to dysfunction of multiple organs and even death.
