Sepsis
Sepsis is a possibly fatal disease that happens when the body's immune system attacks its tissues in response to an infection. When the body's infection-fighting mechanisms kick in, organs work poorly and abnormally.
With sepsis, inflammation and blood clotting decrease blood flow towards the limbs and major organs. This can result in organ failure and sometimes death. More than 1.5 million people in the United States are detected with sepsis each year, with about 30 percent of patients dying.
