What septic shock is caused by?

Septic shock is caused by a severe infection that leads to systemic inflammation and a significant drop in blood pressure. This condition typically arises from bacterial infections, but can also be triggered by fungi or viruses. The body's response to the infection results in widespread vasodilation and impaired blood flow, which can cause organ failure if not treated promptly. Common sources of infection include pneumonia, urinary tract infections, and abdominal infections.
