Overview on blood poisoning

Fact Checked

Blood poisoning or sepsis is a serious form of infection that occurs if bacteria are present in the bloodstream. Immediate diagnosis and treatment are vital in the management of blood poisoning. Understanding the potential risk factors is the initial step in preventing the condition.


What are the causes?

It is important to note that blood poisoning occurs if bacteria that causes an infection in another body part enters the bloodstream. Sepsis occurs if the infection is left untreated. On the other hand, any form of infection can lead to sepsis.

These infections typically affect the abdomen, lungs and urinary tract. Sepsis is likely to occur among hospitalized individuals where the risk is already high.

It is important to note that blood poisoning occurs if bacteria that causes an infection in another body part enters the bloodstream.

Some of the usual cause of infections that can lead to sepsis include:

  • Infected insect bites
  • Abdominal infection
  • Skin infection
  • Kidney or urinary tract infection
  • Pneumonia
  • Infected teeth or dental extractions
  • Infection of the central line such as a dialysis or chemotherapy catheter
  • Infection by a drug-resistant bacterium
  • Infected wound after recovery from surgery or not changing bandages regularly
  • Exposure of open wounds to the environment

What are the risk factors?

  • Young children and elderly
  • Individuals with weakened immune systems such as those with leukemia, HIV and AIDS.
  • Presence of a catheter
  • Individuals who use intravenous drugs including heroin
  • Poor dental hygiene
  • Recent surgery or dental work
  • Environments with high risk of exposure to bacteria or viruses such as in healthcare facilities or outdoors

What are the signs of blood poisoning?

  • Moderate or high fever
  • Chills
  • Rapid breathing
  • Weakness
  • Rapid heart rate or palpitations
  • Pale skin particularly in the face

Some of these signs are linked with the flu or other ailments. Nevertheless, if the individual recently had surgery or recuperating from a wound, a doctor should be consulted right away after these signs manifest.


Immediate treatment for blood poisoning is vital since the infection can rapidly spread to the tissues or heart valves. Once diagnosed with blood poisoning, treatment as an inpatient in a healthcare facility is started.

Oxygen and intravenous fluids are given to maintain the blood pressure and eliminate the infection. Sepsis is managed by maintaining proper hydration with an intravenous line along with antibiotics that target the bacteria responsible for the infection.
