Sepsis is a dangerous body-wide reaction to infection. It can happen when the immune response becomes so intense that it injures tissues, lowers blood pressure, and threatens organs.
Possible warning signs
Warning signs can include confusion, extreme weakness, fever or very low temperature, rapid breathing, fast heartbeat, severe pain, clammy skin, or reduced urination.
Why it is urgent
Sepsis can worsen quickly and may lead to septic shock, organ failure, or death. It is a medical emergency.
Infections such as pneumonia, urinary tract infection, abdominal infection, skin infection, or bloodstream infection can sometimes lead to sepsis.
