What Causes a Sepsis(Blood Infection)?

Blood infection is medically named Sepsis. Sepsis is a potentially life-threatening complication of an infection. If sepsis progresses to septic shock, blood pressure drops dramatically, which may lead to death.

What causes a sepsis?

While any type of infection — bacterial, viral or fungal — can lead to sepsis, the most likely varieties include:

  • Pneumonia
  • Abdominal infection
  • Kidney infection
  • Bloodstream infection (bacteremia)

The incidence of sepsis appears to be increasing in the United States. The causes of this increase may include:

  • Aging population. Americans are living longer, which is swelling the ranks of the highest risk age group — people older than 65.
  • Drug-resistant bacteria. Many types of bacteria can resist the effects of antibiotics that once killed them. These antibiotic-resistant bacteria are often the root cause of the infections that trigger sepsis.
  • Weakened immune systems. More Americans are living with weakened immune systems, caused by HIV, cancer treatments or transplant drugs.

Sepsis is more common and more dangerous if you:

  • Are very young or very old
  • Have a compromised immune system
  • Are already very sick, often in a hospital’s intensive care unit
  • Have wounds or injuries, such as burns
  • Have invasive devices, such as intravenous catheters or breathing tubes
