What are the complications of sepsis?

Severe Illness. Sepsis describes a reaction that the body has to an overwhelming infection. The infection can start anywhere. This occurs for a variety of reasons, but ultimately, the body's response is to release a storm of inflammatory substances that can cause all organ systems to malfunction. If not caught in time. This can lead to organ failure and death.
Organ failure, death. Sepsis is a dangerous condition that can result in severly low blood pressure, heart failure, pulmonary edema requiring a ventilator, kidney failure, delirium, further infection due to malnutrition and weakened immune state, and ultimately death. With aggressive, early treatment in the hospital, these can be mitigated most of the time.
