Comparing Sepsis and Septicemia
Septicemia vs. Sepsis: What Is the Difference?
What Is Septicemia?
Sepsis and septicemia are related medical conditions, but they have slightly different meanings. Let's start with the definitions:
- Septicemia, also known as blood poisoning, occurs when bacteria enter a person's bloodstream and start multiplying and spread throughout the body, releasing toxins. This means harmful bacteria are present and staying in the bloodstream.
- Sepsis, on the other hand, is a severe reaction to an infection. It is a serious complication of septicemia. It occurs when harmful bacteria enter the bloodstream, leading to a widespread inflammatory response throughout the body. This can progress to sepsis or even septic shock.
How Are Sepsis and Septicemia Similar?
- Both sepsis and septicemia are related to infection and can become medical emergencies.
- Both can lead to serious complications if not recognized and treated promptly.
- Septicemia is an older term often used to describe bacteria in the bloodstream, while sepsis refers to the body’s life-threatening response to an infection.
What Are the Main Differences Between Sepsis and Septicemia?
- Septicemia traditionally refers to infection in the bloodstream, especially bacteria in the blood. The related term “bacteremia” more specifically means bacteria are present in the bloodstream.
- Sepsis is not simply an infection in the blood. It is a life-threatening condition that happens when the body’s response to an infection causes organ dysfunction.
- Sepsis can occur with many types of infections, including bacterial, viral, fungal, or parasitic infections. The infection may start in the lungs, urinary tract, abdomen, skin, or another part of the body.
- Septic shock is a severe form of sepsis in which blood pressure remains dangerously low despite treatment with fluids and the body has signs of inadequate circulation. It requires emergency medical care and can be life-threatening.
It’s important to note that sepsis and septicemia are sometimes used interchangeably in everyday language, but they do not mean exactly the same thing medically. If you think you or someone else may have sepsis, seek emergency medical care right away. Only a healthcare professional can diagnose the condition and provide appropriate treatment.
