Sepsis is a serious medical condition that occurs when the body's response to an infection causes widespread inflammation. This can lead to tissue damage, organ failure, and even death if not treated promptly. Common sources of infection include bacteria, viruses, and fungi, which can enter the body through wounds, the lungs, or the urinary tract. Symptoms of sepsis may include fever, increased heart rate, rapid breathing, and confusion. Early recognition and treatment are crucial, often involving antibiotics and fluids. If sepsis progresses to severe sepsis or septic shock, it can become life-threatening, requiring intensive medical care.
