Sepsis (often referred to as either blood poisoning or septicaemia) is a life-threatening illness caused by the body overreacting to an infection.
Symptoms of sepsis
The symptoms of sepsis may develop after a localised infection or injury. In some cases, sepsis may develop when you are already in hospital.
Causes of sepsis
Sepsis can be triggered by an infection in any part of the body. The most common sites of infection leading to sepsis are the lungs, urinary tract, abdomen and pelvis.
Diagnosing sepsis
Sepsis is most often diagnosed by using a blood test. Other tests may be needed to get more information about the infection.
Treating sepsis
Treatment of severe sepsis will vary for each patient depending on the initial infection, the organs affected and the extent of damage.
