When it comes to health concerns you think or worry about, sepsis probably doesn't make the cut. But it's something you should know about, so you can take steps to recognize what causes it and how to prevent it.

Sepsis is an extreme response in your body triggered by an infection you already have. It isn't actually an infection itself, but rather your immune system's response to another infection. It can lead to serious complications like organ failure, tissue damage, or even death without immediate and targeted treatment.

Each year, at least 1.7 million adults in the U.S. develop sepsis, and 270,000 die from it, according to the Centers for Disease Control and Prevention (CDC). Globally, sepsis kills around 11 million people a year, making it one of the leading causes of death around the world.
