Sepsis affects 30 million people each year. It is the leading cause of death for infants and children around the world, despite the fact that early diagnosis followed by broad spectrum antibiotics and IV fluids is all that is required to save a life. In the United States, sepsis affects more that 1 million Americans annually and kills more than 258,000. It leaves thousands of survivors with life-changing disabilities.
Sepsis is the body’s extreme and life-threatening response to an infection. The body releases chemicals into the blood stream to fight the infection but these chemicals trigger inflammatory responses throughout the body which can lead to tissue damage, organ failure, and death.
Sepsis ranges from less to more severe. The goal is to identify and treat sepsis in its earliest stage, before it becomes more dangerous. As sepsis worsens, blood flow to vital organs, such as brain, heart and kidneys, becomes impaired and blood clots can form, leading to organ failure and tissue death. In the most severe cases, blood pressure drops, multiple organs fail, and the patient can die quickly from septic shock. Sepsis can progress very rapidly and is always a medical emergency.
Sepsis is always triggered by an infection. Bacterial, viral or fungal infections anywhere in your body can cause sepsis, although bacterial infections are the most common cause. An infection occurs when germs enter a person’s body and multiply.
The infection can begin anywhere bacteria or other infectious agents can enter the body, including a scraped knee, a tooth abscess, or from a more serious medical problem such as appendicitis, pneumonia, meningitis, or a urinary tract infection.
Sepsis does not discriminate. It affects young and old, rich and poor, sick and healthy. Anyone can get sepsis at any time as a bad outcome from an infection.
Those at higher risk of developing sepsis include:
Sepsis presents itself as a combination of symptoms, rather than a single sign.
If two of the following signs are present, seek immediate medical assistance.

Doctors diagnose sepsis by checking for fever, increased heart rate, and increased breathing rate. A blood test will show if there is an abnormal white blood cell count – a common indicator of sepsis. Doctors may also test blood and other bodily fluids such as urine and sputum for the presence of bacteria and other infectious agents. X-ray and scans may be performed to identify or confirm the source of the infection.
Doctors treat sepsis with antibiotics as soon as possible. Many patients receive oxygen and intravenous (IV) fluids to keep the vital organs working and prevent a drop in blood pressure.
Assisted breathing or kidney dialysis may also be necessary. Sometimes surgery is required to remove tissue damaged by the infection or limbs that have succumbed to gangrene.
If treated swiftly, many people recover from sepsis and their lives return to normal. Some who survive may have impaired physical or neurocognitive functioning, mood disorders, and a low quality of life. Also, an episode of severe sepsis may place you at higher risk of future infections. The mortality rate for septic shock is nearly 50 percent.
Sepsis is not completely preventable but you can reduce the likelihood of developing sepsis by:
