R50-R69: General symptoms and signs
R65: Systemic Inflammatory Response Syndrome [SIRS]
Systemic Inflammatory Response Syndrome (SIRS) is a group of conditions that can occur when the body's immune response is out of balance. Usually triggered by an infection or other severe physical health issues, SIRS could potentially affect every system in your body. Typical symptoms include fever or low body temperature, fast heart rate, quick breathing, and a change in the number of white blood cells. Not every person with SIRS will have all these symptoms, but they can come on swiftly and progress rapidly. It's vital to spot these symptoms early as SIRS can develop into more severe conditions such as sepsis and multi-organ dysfunction syndrome, which can be life-threatening.
