Septic shock is a life-threatening condition that happens when your blood pressure drops to a dangerously low level after an infection. Any type of bacteria can cause the infection. Fungi such as candida and viruses can also be a cause, although this is rare. At first the infection can lead to a reaction called sepsis.

What is the most common cause of septic shock?

Bacterial infections are the most common causes of sepsis. They can originate externally in wounds or as a result of conditions such as pneumonia. Anyone who suspects that they or someone else may have sepsis or have gone into septic shock should seek emergency care.

What happens to the body during septic shock?

As sepsis worsens, blood flow to vital organs, such as your brain, heart and kidneys, becomes impaired. Sepsis may cause abnormal blood clotting that results in small clots or burst blood vessels that damage or destroy tissues. Most people recover from mild sepsis, but the mortality rate for septic shock is about 40%.
