Sepsis is when the body has an unusually severe response to an infection. It’s sometimes called septicemia. During sepsis, the immune system, which defends the body from germs, releases a lot of chemicals into blood. This triggers widespread inflammation that can lead to organ damage. Clots reduce blood flow to the limbs and internal organs, so they don’t get enough nutrients and oxygen. In severe cases, sepsis causes a dangerous drop in blood pressure. Doctors call this “septic shock.” It can quickly lead to organ failure, such as your lungs, kidneys, and liver. This can be deadly. Bacterial infections are most often to blame for sepsis. But it can also happen because of other infections. It can begin anywhere bacteria, parasites, fungi, or viruses enter your body, even something as small as a hand nail.
Symptoms are fever and chills, very low body temperature, fast heartbeat, nausea and vomiting, diarrhea, fatigue or weakness, blotchy or discolored skin, sweating or clammy skin, severe pain.
Sepsis is diagnosed through physical exam, blood tests, and imaging through x-ray, CT or ultrasound.
Broad-spectrum antibiotics, IV fluids, and extra oxygen are used to treat sepsis.
