Normal puerperium and postnatal care

It is day 4. She is on the postnatal ward, her observations are unremarkable, and she tells you she just does not feel right. The temptation is to reassure her: this is all normal, everyone feels like this. That sentence, said to the wrong woman, is the single most repeated error in maternal death enquiries — and the whole point of this topic is knowing which physiology earns reassurance and which does not.^[18][19]

Overview and definition

The puerperium runs from delivery of the placenta to about six weeks, the point at which most non-lactational systems have returned to their pre-pregnant state. ^[4][5]

• The classical frame: six weeks, ending with a single postnatal check.
• The modern frame: the "fourth trimester", a twelve-week transition in which care is an ongoing process rather than one appointment — the framing ACOG adopted in Committee Opinion 736.^[4]
• Why the change matters: the single six-week visit systematically missed the mood disorders, the contraceptive need and the cardiometabolic follow-up that cluster in weeks 2 to 12.^[4][8]

NICE named the problem out loud when NG194 was published: postnatal care is the "Cinderella service" of maternity — the least resourced part of a well-resourced pathway.^[1]
