Why does endometritis cause fever after birth?

Short answer
Endometritis causes fever after birth because bacteria in the uterine lining trigger inflammation, which raises body temperature as the immune system responds.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

Why fever can develop
Fever After Birth is a very common presentation of Endometritis. After delivery, the inside of the uterus is healing and the cervix has been open, allowing bacteria to enter more easily. Infection of the uterine lining can cause fever, chills, lower abdominal tenderness, feeling unwell, and foul-smelling vaginal discharge. The uterus may also remain tender or fail to shrink as expected. Fever after birth has other possible causes, so a clinician needs to assess the full pattern.
What to do now
Contact your maternity team or a clinician promptly if you develop a fever or feel increasingly unwell after birth. They may check your temperature, abdomen, bleeding, discharge, and other possible infection sources. Endometritis is commonly treated with antibiotics; take them exactly as prescribed and complete the course unless your clinician changes it. Ask which medicines are compatible with breastfeeding.
When to seek urgent care
Seek urgent medical care for severe weakness, confusion, fainting, trouble breathing, rapidly worsening pain, shaking chills, or heavy bleeding. Do not wait for a routine appointment if you feel seriously unwell after delivery.
Questions for your doctor
Ask what may be causing the fever, whether you need tests, which antibiotic is planned, how to monitor improvement, and what symptoms should prompt immediate reassessment.
