Understanding the difference between infection and sepsis
An infection happens when harmful bacteria, viruses, fungi or parasites enter the body and multiply, causing damage and illness. Sepsis, on the other hand, is the body's extreme reaction or response to an infection, which can potentially lead to organ failure and can become life-threatening if not treated promptly.
Symptoms that indicate an infection may have progressed to sepsis
- Rapid or difficult breathing
- Confusion or disorientation
- Fever, chills, or feeling extremely cold
- Rapid heartbeat or low blood pressure
- Reduced urine output
- Pale or mottled skin colour
Can an infection always lead to sepsis?
No, an infection does not always progress to sepsis. In most cases, infections can be effectively treated with antibiotics or antiviral medications without severe complications. However, if an infection worsens or is left untreated, or if someone has a weakened immune system, the risk of developing sepsis increases significantly.
How quickly can an infection turn into sepsis?
An infection can develop into sepsis very quickly, sometimes within hours. Prompt treatment of an infection can help prevent sepsis from occurring. If you suspect sepsis, seek medical attention immediately—early intervention is crucial for successful treatment and recovery.
Who is most at risk of developing sepsis from an infection?
- Very young children and infants
- Elderly people (those over 65)
- Individuals with weakened immune systems, such as cancer patients undergoing chemotherapy
- People with chronic illnesses such as diabetes, kidney disease, or lung disease
- Patients recovering from surgery or recent hospitalisation
When should you seek medical help for suspected sepsis?
If you or someone you know experiences any symptoms of sepsis, including rapid breathing, confusion, extreme shivering, fever or chills, fast heartbeat, or unusual changes in skin colour, seek emergency medical assistance immediately. Rapid medical attention significantly reduces the risk of severe complications or death.
Sadly medical practitioners can sometimes be slow to identify and respond to the signs of sepsis and this can lead to avoidable and potentially significant complications.
