Stages of sepsis include; uncomplicated sepsis caused by infections such as flu. Severe sepsis occurs when the body's response to infection begins to interfere with the function of vital organs, such as the heart, kidneys, lungs or liver. Septic shock occurs when the blood pressure drops to dangerously low levels, preventing vital organs from receiving enough oxygenated blood.
