An inflammatory response to an infectious process that may trigger a failure of one or more organs and systems

Sepsis is a serious, life-threatening medical emergency. It is caused by the body's response to an infection - in the skin, urinary tract, lungs, or elsewhere, the origin of that infection can be located anywhere in the body, such as: - triggering a whole-body reaction. Bacterial infections are the most common cause of Sepsis. 

Sepsis develops when chemicals present in our Immune System act as a fighting response to an infection and are released unevenly throughout the bloodstream, causing inflammation throughout the body that, when it gets worse, leads to septic shock. 

There are three stages: Sepsis, Severe Sepsis, and Septic Shock. If you have any of the following symptoms, seek medical attention immediately. Without prompt treatment, Sepsis can lead to very rapid tissue damage and organ failure.

Causes and Risk

Causes and Risk

Causes of Sepsis:

Sepsis can be caused by bacterial, fungal, parasitic, or viral infections. The places and types of infection that can trigger Sepsis are:

  • Bloodstream

  • Liver or Gallbladder

  • The skin (through wounds, skin inflammation or cellulite)

  • Abdomen (appendicitis, intestinal problems, peritonitis)

  • Central Nervous System (Brain or Spinal Cord Infections)

  • Lungs (Bacterial Pneumonia)

  • Urinary Tract (urinary tract infection, pyelonephritis, urosepsis)

  • Bones (common in children)


Preventing an infection from spreading is very important to avoid Sepsis, some ways are:

  • Receiving all recommended immunizations

  • Have good hygiene: in addition to bathing and washing your hands regularly and adequately, wound care is essential

  • If you have any signs of infection, seek medical attention immediately

  • Timely removal of bladder and IV tubes when they are no longer needed
