According to the text, septic shock is a severe drop in blood pressure that occurs as a result of an infection. It is the most severe form of sepsis, which is a life-threatening condition caused by an extreme reaction of the immune system to an infection. Symptoms of septic shock include difficulty standing and may lead to death if not treated promptly. Septic shock affects major organs and body systems, and patients are often considered the "sickest patients." It is important to seek medical attention immediately for any infection that is not improving or getting worse.
