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.

If you have an infection

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.

Signs of sepsis during and after pregnancy

Emergency action required: Call 999 or 112, or go to ED if:

you or someone you look after have any of these signs of sepsis:

  • acting confused, slurring their speech, not making sense or not their usual self
  • difficulty breathing, breathlessness or breathing very fast
  • feel pounding in their chest
  • their hands or feet feel cold, clammy and pale
  • feels dizzy, faint or loses consciousness (passes out)
  • not peeing as much as normal – for example, not peeing for a day
  • a rash that does not fade when you roll a glass over it, in the same way you check for meningitis
  • severe muscle pain
  • have severe leg pain or difficulty standing
  • are extremely unwell or feel like there's something seriously wrong
