Postpartum period (Puerperal period)


The postpartum period refers to the six-to-eight-week period after the birth of a baby in which the body recovers from the changes caused by pregnancy and birth. During this time, the body undergoes several physiological changes, such as uterine involution, discharge of lochia, and the beginning of the lactation process. Women are also susceptible to complications during the postpartum period, such as infection, thrombosis, insufficient postpartum recovery, and postpartum depression. The fundal height measurement and the appearance of lochia (postpartum vaginal discharge) provide important clues to possible underlying conditions.

Normal postpartum changes

Low‑grade fever, shivering, and leukocytosis are common findings during the first 24 hours postpartum and do not necessarily indicate an infection.

Uterine involution

Lochia (postpartum vaginal discharge)

  • Definition
    • The birthing process and placental detachment lead to uterine lesions, which discharge a special secretion when healing.
    • This secretion, together with the cervical mucus and other components, forms the lochia.
  • Most women pass lochia for about 4 weeks after delivery; in some cases, this lasts for 6–8 weeks.
    • Lochia rubra: blood red; approx. the first 4 days after birth
    • Lochia serosa: brown red; watery consistency, lasts approx. 2–3 weeks
    • Lochia alba: yellow white; lasts approx. 1–2 weeks

Lactation and breastfeeding


Breast milk composition

Breast milk contains all the required nutrients (except vitamin D and vitamin K) for infants up to 6 months of age.

Because breast milk does not contain sufficient amounts of vitamin D, vitamin K, and iron, supplementation is vital!
