What is the definition of sepsis?

Sepsis is defined as the body's extreme response to infection, which occurs when the immune system goes into overdrive in an attempt to fight off an infection. This reaction can lead to widespread inflammation, causing blood flow to be compromised and potentially resulting in organ dysfunction. It is a critical condition that can escalate to severe sepsis or septic shock, both of which require immediate medical attention. Recognizing sepsis early is crucial for effective treatment, as it can progress rapidly and lead to life-threatening complications.

In the context of the other options, while low blood sugar, fluid overload in the lungs, and high blood pressure are medical conditions that require attention, they do not describe the systemic response that characterizes sepsis. Low blood sugar pertains to glucose levels, fluid overload is associated with heart or kidney issues, and high blood pressure relates to cardiovascular health, none of which encompass the immune response to infection represented in the correct definition.
