postpartum period; puerperium
Medical term for the approximately 6–8 weeks after childbirth during which the mother's body returns to its pre-pregnancy state.
Adequate rest is necessary during the postpartum period.
If you notice any abnormalities during the puerperium, consult a doctor immediately.
Compound of 産 (birth) + 褥 (bedding, lying-in) + 期 (period). The term is a direct medical borrowing from Chinese, where 産褥期 (chǎnrùqī) is also used.
