Postpartum Sepsis (Puerperal Sepsis): Symptoms, Risks, and UK Healthcare Guidance

Postpartum sepsis, also known as puerperal sepsis, is a severe infection that occurs following childbirth, miscarriage, or termination. While the UK has high standards of maternity care, maternal sepsis remains a significant cause of illness and, in rare cases, mortality. According to NICE (National Institute for Health and Care Excellence), sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection.

In the weeks following birth, the body is particularly vulnerable as the uterus heals and the cervix closes. If bacteria enter the bloodstream or reproductive tract during this period, the immune system may overreact, leading to tissue damage and organ failure. Early diagnosis is the most critical factor in ensuring a full recovery for new mothers.

Common Early Signs

Symptoms of an infection after birth may start mildly but can escalate rapidly. It is vital to monitor for:

• High temperature: A fever above 38°C or a very low body temperature.
• Shivering and chills: Uncontrollable shaking or feeling extremely cold.
• Abdominal pain: Severe tenderness in the lower tummy that is worse than standard after-birth cramping.
• Vaginal discharge: A sudden increase in bleeding or discharge that has an offensive, foul smell.
• Tachycardia: A fast heart rate or feeling like your heart is racing.

If you experience these symptoms, you should contact your midwife or GP immediately. Do not wait for your scheduled six-week postnatal check if you feel unwell.

Most cases of postpartum sepsis are caused by bacteria such as Streptococcus (Group A or B) or E. coli. These infections often originate in the following ways:

• Endometritis: Infection of the lining of the womb.
• Wound Infections: Infections at the site of a C-section incision or an episiotomy/tear.
• Mastitis: A breast infection that, if left untreated, can lead to systemic sepsis.
• Urinary Tract Infections (UTIs): Common after catheterisation during labour.

Certain factors can increase the risk of developing sepsis, including prolonged rupture of membranes (waters breaking early), multiple vaginal examinations during labour, or having a history of gestational diabetes. The NHS emphasizes that any woman can develop sepsis regardless of how healthy her pregnancy was.

In the UK, healthcare professionals use a protocol known as the 'Sepsis Six' to manage the condition. Within the first hour of a sepsis diagnosis in a hospital setting, clinicians aim to provide oxygen, take blood cultures, start intravenous antibiotics, give IV fluids, check lactate levels, and monitor urine output. This rapid intervention is designed to stabilise the mother and prevent long-term complications such as kidney failure or lung injury.

For patients at home, the 'Sepsis Six' serves as a reminder that every minute counts. If you suspect you have an infection, being proactive about seeking help can be life-saving.

If you are feeling generally unwell after birth but do not have red-flag symptoms, you may wish to speak to a GP online for an initial assessment. An online doctor in the UK can help determine if your symptoms require an urgent face-to-face referral or if you are experiencing a localized infection, such as mild mastitis or a simple UTI, which may be treated with oral antibiotics.

Our clinicians can review your symptoms, provide advice on wound care for C-section scars, and issue prescriptions where appropriate. However, if you are showing signs of systemic illness, such as confusion, extreme shivering, or a very high fever, you must bypass online services and go directly to A&E.

Treatment for postpartum sepsis almost always requires hospitalisation. You will typically be given intravenous antibiotics to target the infection quickly. Fluids will be administered through a drip to maintain blood pressure and protect your organs. Most women will stay in the hospital for several days for monitoring.

Recovery can take time, both physically and emotionally. It is common to feel extremely tired (lethargy), experience muscle pain, and have difficulty concentrating (brain fog) for weeks or even months following sepsis. Support from your health visitor and GP is essential during this time to monitor for 'Post-Sepsis Syndrome'.
