Postpartum Period

The period extending from delivery of the placenta through to approximately six weeks following childbirth, during which the maternal body undergoes a substantial, coordinated process of physiological involution and readjustment following pregnancy and delivery.

This encompasses uterine involution, resolution of pregnancy-related haemodynamic and metabolic changes, lactation establishment, and psychological adaptation to the postpartum state.

Full, structured postpartum care is essential to supporting normal physiological recovery, identifying and promptly addressing any postpartum complication, and supporting the substantial physical, psychological, and practical adjustment required during this significant life transition.

Normal physiological changes

• Uterine involution, the progressive reduction in uterine size following delivery, proceeds at a generally predictable rate.
• The uterine fundus is typically palpable at or near the umbilicus immediately following delivery, then progressively descends and becomes impalpable abdominally by approximately two weeks postpartum.
• This reflects the coordinated process of myometrial contraction and, at the cellular level, controlled tissue remodelling and reduction in cell size.
• Lochia, the postpartum vaginal discharge comprising blood, decidual tissue, and mucus, follows a characteristic, expected evolution:
  • lochia rubra: an initial heavier, bright red discharge, typically for the first few days
  • lochia serosa: a lighter, pinkish-brown discharge, typically over the following one to two weeks
  • lochia alba: a final, minimal yellowish-white discharge, typically continuing for a further several weeks
• Any significant deviation from this expected pattern, including heavy, prolonged, or malodorous discharge, warrants further evaluation for underlying complication.
• Substantial haemodynamic and metabolic changes occur during the immediate postpartum period.
• There is a significant, physiological increase in cardiac output and blood volume in the immediate hours following delivery, reflecting relief of aortocaval compression and the "autotransfusion" of blood from the contracting uterus.
• A gradual return toward pre-pregnancy physiological parameters follows over the subsequent weeks.
• This period of haemodynamic flux carries particular relevance to women with significant underlying cardiac disease.
• Lactogenesis and breastfeeding establishment are a central physiological process during this period.
• They are driven by the substantial postpartum fall in oestrogen and progesterone (removing their inhibitory effect on prolactin action), together with ongoing prolactin secretion and the local, mechanical stimulus of infant suckling.
• Successful lactation establishment is substantially supported by early, frequent skin-to-skin contact and breastfeeding initiation, together with appropriate, accessible lactation support.

• Normal postpartum recovery encompasses the physiological changes, together with a range of common, generally self-limiting physical symptoms:
  • afterpains: uterine cramping, particularly prominent during breastfeeding given the oxytocin-mediated uterine contraction this stimulates, and typically more pronounced in multiparous women
  • perineal discomfort, particularly following vaginal delivery with associated perineal trauma
  • breast engorgement and, in the early days, nipple tenderness during breastfeeding establishment
  • generalised fatigue
• Significant psychological and emotional adjustment characterises the postpartum period.
• It ranges from the extremely common, generally mild and self-limiting "baby blues" (transient mood lability, tearfulness, and emotional sensitivity, typically peaking around the third to fifth postpartum day and resolving spontaneously within one to two weeks) through to more significant postpartum mental health conditions.
• These conditions are addressed under postpartum complications.
• Careful, proactive clinical attention and screening are warranted throughout this period.
• Physical recovery following vaginal delivery generally proceeds more rapidly than following caesarean delivery, though individual variation is substantial.
• The pattern and pace of recovery are influenced by numerous factors, including parity, the mode and any complications of delivery, and broader maternal health and support circumstances.
• The postpartum period is a time of substantial practical and social adjustment.
• It encompasses infant care demands, sleep disruption and, frequently, significant change to relationship dynamics, social roles and, where relevant, return to employment planning.
• The cumulative impact of these physical, psychological, and practical demands warrants full, holistic clinical attention rather than a narrow, purely physical focus.

• Structured postpartum assessment typically incorporates an initial, full check before hospital discharge and subsequent follow-up at defined intervals.
• These commonly include assessment within the first one to two weeks and a more full assessment around six weeks postpartum, according to local protocols.
• It addresses physical recovery (including assessment of uterine involution, perineal or caesarean wound healing, and lochia pattern), breastfeeding progress, and psychological wellbeing.
• Screening for postpartum depression and other relevant mental health concerns, using validated, structured screening tools where available, represents an essential, standard component of postpartum assessment given the significant prevalence and frequently underrecognised nature of these conditions.
• Full assessment for any feature suggestive of an evolving postpartum complication warrants prompt, specific further evaluation according to the standard principles for the underlying condition.
• Features include excessive or malodorous lochia, fever, significant, worsening perineal or wound pain, breast symptoms suggestive of mastitis, and symptoms suggestive of venous thromboembolism (given the recognised, elevated risk during this period).

• Full, structured postpartum care encompasses ongoing support for physical recovery, including appropriate analgesia for afterpains and perineal or wound discomfort, and general advice regarding activity, hygiene, and gradual return to normal function.
• It also includes structured lactation support and full contraceptive counselling, addressing contraceptive options relevant to the postpartum period and, where relevant, breastfeeding status.
• Proactive, structured mental health screening and support is an essential, integral component of full postpartum care.
• Provide clear, accessible information for the woman and her family on the expected pattern of normal emotional adjustment and the specific features that would warrant further evaluation for a more significant postpartum mental health concern.
• Full immunisation review and, where relevant and not already addressed during pregnancy, administration form an appropriate component of postpartum assessment.
• This includes rubella immunity assessment and, where indicated, vaccination in a non-immune woman, given the relevance to future pregnancy planning.
• Review any relevant ongoing medical condition and its management in the postpartum context.
• Clear, full discharge planning and structured follow-up arrangements underpin safe, supportive postpartum care across this multifaceted period of physical, psychological, and practical maternal adjustment.
• Provide accessible information on relevant support services, and clear guidance on when and how to seek further assessment should any concerning symptom develop.
