Postpartum haemorrhage: what it is and how it's handled

Postpartum haemorrhage — heavy bleeding after birth, usually shortened to PPH — is one of those topics that sounds terrifying in a headline and looks very different up close. Yes, it’s the complication maternity teams take most seriously in the hours after birth. It’s also one they are superbly drilled at handling: it’s common enough that every birth suite rehearses it, treatments work, and the vast majority of women who experience a PPH recover fully. Knowing the shape of it in advance is protective, not morbid.

What counts as a PPH. Some bleeding after birth is universal — the placenta leaves behind a wound that heals over weeks of normal postpartum bleeding (lochia). A PPH means losing more blood than expected: a primary PPH happens within 24 hours of birth (affecting somewhere between one in twenty and one in ten births, most of them at the milder end), while a secondary PPH is abnormal bleeding from 24 hours up to twelve weeks later, usually caused by infection or a fragment of retained placenta.

Why it happens. Clinicians teach it as the four Ts. Tone is the big one, in about seven of ten cases: after the placenta detaches, the uterus is supposed to clamp down hard, squeezing its blood vessels shut — if it stays relaxed (more likely after a long labour, a big baby, twins, or many previous babies), those vessels keep bleeding. The others: trauma (bleeding from a tear or the caesarean wound), tissue (a piece of placenta left behind, stopping the uterus closing fully), and thrombin (a clotting problem, the rarest). Some things raise the odds — a previous PPH, placenta praevia, pre-eclampsia, induction, being anaemic going in — and if any apply to you, your team will already have quietly planned for it: it’s a standard line in birth planning, and one reason iron levels get so much attention in the third trimester.

How it’s handled in the moment: fast and methodically. The uterus gets rubbed firmly to stimulate contraction, medicines like oxytocin drive it to clamp down, a catheter empties the bladder (a full one blocks the uterus contracting), any tear is stitched, retained tissue is removed (sometimes in theatre), and fluids — occasionally a blood transfusion — replace what’s lost. It’s a well-rehearsed choreography: expect the room to fill with calm, purposeful people. For the small minority where bleeding continues, there are further steps (a pressure balloon inside the uterus, surgical measures), but most PPHs are controlled quickly with the simple ones. This choreography is also why the active-management injection in the third stage is recommended — it’s the main preventive lever.

Afterwards, the footprint is mostly tiredness: blood loss plus a newborn is a heavy combination, and you may need iron (or have had a transfusion), extra rest and more help than the standard postpartum allocation. Take the recovery seriously and stack the village accordingly. It’s also normal for a PPH to leave emotional sediment — a fright at the moment you were meant to be celebrating. Talking the event through with your midwife, obstetrician or GP (ask for a birth debrief — it’s a real thing you can request) genuinely helps, and if the memory stays loud, that’s worth naming to your GP rather than carrying.

For home, know the secondary-PPH red flags: bleeding that suddenly gets much heavier after settling — soaking a pad an hour, or clots bigger than a 50-cent piece — smelly discharge, fever, or feeling faint. Heavy sudden bleeding means 000; the rest means your midwife or GP the same day. Trust the pattern: lochia should trend lighter week on week, and anything moving the other way deserves a phone call. Your care team would far rather check ten false alarms than miss one real one — so call.
