Sepsis is like when your body gets really confused and starts fighting itself because it thinks there are bad germs everywhere, even if they're not really there. Imagine if your superhero team got mixed up and started battling each other instead of the villains. This can make you feel very sick, with a high fever or feeling really cold, and it can be hard for doctors to help. They need to work quickly to figure out what’s wrong and give you special medicine to help your superhero team stop fighting itself and focus on getting better.
Sepsis is defined medically as a life-threatening organ dysfunction caused by a dysregulated host response to infection. It occurs when the body's response to an infection injures its own tissues and organs. This condition can lead to shock, multiple organ failure, and death, especially if not recognized early and treated promptly.
