Answer:
Sepsis is caused by your body’s defense system (immune system) working overtime to fight infection. It’s sometimes called septicemia. The large number of chemicals released into the blood during this process triggers widespread inflammation. This can lead to organ damage. Blood clotting during sepsis reduces blood flow to limbs and internal organs. This deprives them of nutrients and oxygen. In severe cases, one or more organs may fail. In the worst cases, sepsis leads to a life-threatening drop in blood pressure. Doctors call this “septic shock.” It can quickly lead to the failure of several organs -- lungs, kidneys, and liver. This can be fatal in some cases.
