Overview

Septic shock is a life-threatening condition that happens when blood pressure drops to a dangerously low level after an infection.

This reduces the amount of blood and oxygen that reaches the body's organs, stopping them working properly.

Septic shock can occur as a complication of sepsis, a serious condition that happens when the body's reaction to an infection damages its own tissues and organs.

Symptoms

Symptoms of septic shock may develop if sepsis is left untreated. These can include:

Treatment

Treatment is usually carried out in a hospital intensive care unit (ICU).

It may include:

  • fluids given into a vein
  • antibiotics given into a vein
  • medicines that increase blood pressure and help blood reach tissues and organs
  • surgery to remove the source of the infection (such as an abscess) and any tissue that has been badly damaged by the infection
  • oxygen given through a face mask, a tube in the nose, or a tube passed down the throat
  • a breathing machine (ventilator) if breathlessness is severe

It's likely someone with septic shock will need to stay in hospital for several weeks.

Risks

Anyone can develop septic shock, but it's most common in people with a weak immune system, the body's natural defences against illness and infection.

This includes:

Septic shock often occurs in people who are already in hospital for another reason.
