Sepsis is the body’s overwhelming and life-threatening response to infection that can lead to tissue damage, organ failure, and death. In other words, it’s your body’s overactive and toxic response to an infection.
Your immune system usually works to fight any germs (bacteria, viruses, fungi, or parasites) to prevent infection. If an infection does occur, your immune system will try to fight it, although you may need help with medication such as antibiotics, antivirals, antifungals, and antiparasitics. However, for reasons researchers don’t understand, sometimes the immune system stops fighting the “invaders,” and begins to turn on itself. This is the start of sepsis.
