Sepsis during and after pregnancy - Sepsis

Maternal sepsis is the name for sepsis that develops during pregnancy or up to 6 weeks (42 days) after:

  • the birth
  • a miscarriage
  • an abortion

Maternal sepsis is rare, but it can be life threatening.

Signs of sepsis during and after pregnancy

If you have an infection, know the signs of sepsis. It’s important to get treatment early if you need it.

You can only develop sepsis if you have an infection.

Emergency action required: Call 112 or 999 or go to your nearest emergency department (ED) if

you or someone you are caring for has any of these signs of sepsis:

  • feeling extremely unwell or like something is wrong
  • taking antibiotics for an infection and not getting better
  • difficulty breathing, breathing very fast or shortness of breath
  • cold, clammy and pale hands or feet
  • feeling dizzy, faint or losing consciousness (passing out)
  • acting confused, slurring your speech, not making sense or not your usual self
  • feeling a pounding in your chest
  • not peeing as much as normal - for example, not peeing for 1 day
  • a rash that does not fade under a glass - the same way you check for a meningitis rash
  • severe muscle pain
  • severe leg pain or difficulty standing

You may not have all these symptoms. Even if you have just 1, get urgent medical help.

Be aware if you have an infection

You may be more at risk of becoming very unwell due to an infection when you are pregnant. This is because your immune system changes during pregnancy.

you are pregnant or have recently been pregnant and have any of these signs of an infection:

  • low temperature (under 36 degrees Celsius)
  • severe uncontrollable shivering
  • feeling tired (fatigue)
  • loss of appetite
  • muscle and joint pain
