Sepsis
Last Updated: July 3, 2026
Key Points
- Serious, life-threatening reaction to an infection
- Develops quickly and needs urgent hospital treatment
- Body's immune system overreacts, damaging organs
- Can lead to septic shock and death if untreated
Overview
Sepsis is a severe and rapid reaction to an infection in your body. Instead of fighting the infection, your immune system overreacts, causing widespread inflammation that can damage your own tissues and organs. This condition develops very quickly and can become life-threatening. It can be triggered by any type of infection, most commonly bacterial ones like pneumonia, urinary tract infections, or skin infections. The exact reason for the immune system's overreaction isn't fully understood, but factors like age, genetics, and existing health conditions can play a role. Sepsis requires immediate medical attention and hospital treatment, often involving antibiotics, oxygen, and fluids. Early diagnosis and treatment are crucial for survival and recovery, as delays can lead to severe complications or death.
