Sepsis

What Is Sepsis?

Sepsis is when your body has an unusually severe response to an infection. It’s sometimes called septicemia.

During sepsis, your immune system, which defends you from germs, releases a lot of chemicals into your blood. This triggers widespread inflammation that can lead to organ damage. Clots reduce blood flow to your limbs and internal organs, so they don’t get the nutrients and oxygen they need.

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.

Sepsis Causes and Risk Factors

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 hangnail.

An infection of the bone, called osteomyelitis, could lead to sepsis. In people who are hospitalized, bacteria may enter through IV lines, surgical wounds, urinary catheters, and bed sores.

Sepsis is more common in people who:

• Have weakened immune systems because of conditions like HIV or cancer or because they take drugs such as steroids or those that prevent rejection of transplanted organs
• Are pregnant
• Are very young
• Are elderly, especially if they have other health problems
• Were recently hospitalized or had major surgeries
• Use catheters or breathing tubes
• Have diabetes
• Have a serious medical condition such as appendicitis, pneumonia, meningitis, cirrhosis, or a urinary tract infection

Sepsis Symptoms

Because it can begin in different parts of your body, sepsis can have many different symptoms. The first signs may include rapid breathing and confusion. Other common symptoms include:

• Fever and chills
• Very low body temperature
• Peeing less than usual
• Fast heartbeat
• Nausea and vomiting
• Diarrhea
• Fatigue or weakness
• Blotchy or discolored skin
• Sweating or clammy skin
• Severe pain

Sepsis Diagnosis

Your doctor will do a physical exam and run tests to look for things like:

• Bacteria in your blood or other body fluids
• Signs of infection on an X-ray, CT scan, or ultrasound
• A high or low white blood cell count
• A low number of platelets in your blood
• Low blood pressure
• Too much acid in your blood (acidosis)
• A lack of oxygen in your blood
• Problems with how your blood clots
• Uneven levels of electrolytes
• Kidney or liver problems
