Septic Shock

Septic shock is a life-threatening condition that happens when your blood pressure drops to a dangerously low level after an infection. The infection will first cause a response from the body known as sepsis (see the box on this page). If sepsis is not treated, it can lead to severe sepsis and septic shock. 

Infective microorganisms can infect the blood, causing septicaemia and leading to septic shock.

Sepsis

Sepsis is a life-threatening illness caused by the body overreacting to an infection. The body’s immune system goes into overdrive, setting off a series of reactions that can lead to widespread inflammation (swelling) and blood clotting.
