Postpartum Constipation and the First Poo

Why the first poo takes so long

Several things line up against you at once. Your bowel has been squashed and slowed by pregnancy hormones for months. You may not have eaten much during labour. Pain relief, especially anything opioid-based, slows the gut further. You are dehydrated, sore, and understandably reluctant.

The NHS sets the expectation without drama: "You probably won't have a poo for a few days after the birth, but it's important not to let yourself get constipated."

That sentence contains both halves of the problem. A few days is normal. Letting it run past that is not, because straining is the thing you most want to avoid while your pelvic floor and any stitches are healing.

What is normal

• No bowel movement for the first two or three days.
• Wind before anything else, sometimes uncontrollably. The HSE notes that a nerve controlling the anal sphincter can be stretched during birth, so "you may find it hard to control farts or poo. This will also improve."
• Piles. The NHS says they are "very common after birth but usually disappear within a few days or weeks."
• Fear. Almost universal, and worth naming, because it is the fear rather than the physiology that keeps most people on the sofa.

Your stitches will not burst

This is the single most useful fact on the page, and it comes from the people who repair the tears.

The RCOG: "If you have stitches, opening your bowels should not open them." The NHS: "If you've had stitches, it's very unlikely you'll break them, or open up the cut or tear again."

After a third- or fourth-degree tear you will normally be given laxatives for the first few days precisely so you do not have to strain. The RCOG warns that they sometimes work rather well: "you may struggle to get to the toilet in time. This should improve and settle over the first few days."

What actually helps

The advice below comes from the RCOG, the NHS, the HSE and ACOG, and it is consistent across all four. None of it is exotic, and that is rather the point: there is no clever trick, only mechanics.

• Position. The RCOG: "It can be helpful to put your feet on a footstool, to raise your knees above your hips while sitting on the toilet. Try to relax and rest your elbows on your knees." The HSE says the same and adds bending slightly forward.
• Breathe out, do not bear down. The RCOG: "Do not strain as this weakens your pelvic floor. Bulge out your tummy by taking big abdominal breaths, which will help expel your stool without straining." The HSE's version is memorable: "Avoid pushing. Take your time and breathe like you're blowing bubbles."
• Water. The RCOG: "You should drink at least 2 litres of water every day."
• Fibre. The NHS: "Eat plenty of fresh fruit, vegetables, salad, wholegrain cereals and wholemeal bread, and drink plenty of water."
• Support the stitches. The NHS: "It might feel better if you hold a pad of clean tissue over the stitches when pooing."
• Move. ACOG suggests taking short walks as soon as you can.
• Do not delay. The RCOG: "Don't delay if you have the urge to empty your bowels." Ignoring the urge because the baby is feeding is how a two-day gap becomes a five-day one.
• Ask about a laxative or stool softener. The NHS: "Talk to your midwife or GP if you have constipation that won't go away. A gentle laxative may help." ACOG suggests asking about a stool softener, particularly if you have stitches or piles.

For piles, the HSE has a specific and slightly counterintuitive tip: "Sitting on a flotation ring can give temporary relief but actually make the problem harder to clear. Instead, place a folded hand towel under each thigh while sitting."

When to call

Talk to your GP or midwife if:

• you go more than three days without a bowel movement. The HSE gives this as a specific threshold
• constipation is not shifting despite fibre, fluid and a gentle laxative
• you are in a lot of pain when you go, or afterwards
• you find it hard to pee, it is very painful to pee, or your urine smells strong or unpleasant (HSE: contact your midwife or GP immediately)

Tell your midwife, health visitor or GP as soon as possible if: "poo is leaking or you're pooing when you don't mean to." That is the NHS's wording, and the RCOG asks you to report struggling to make it to the toilet or to control wind even after a first- or second-degree tear. These symptoms are common, treatable, and consistently under-reported because they are embarrassing. NICE's pelvic floor guideline explicitly tells clinicians to expect that embarrassment and to work around it.

Contact your midwife, GP or maternity unit the same day if constipation comes with a fever, severe or worsening tummy pain, or bleeding that is getting heavier — those point at infection rather than a sluggish bowel.

Constipation is a pelvic floor issue, not just a bowel one

NICE's guideline on pelvic floor dysfunction (NG210) lists constipation as a modifiable risk factor for pelvic floor dysfunction, alongside a BMI over 25, smoking and lack of exercise. Its dietary recommendation is aimed at exactly this: eat enough fibre, "because this can improve stool consistency and prevent symptoms of faecal incontinence."

So the reason to take postnatal constipation seriously is not just the discomfort of the first week. Repeated straining in the weeks after birth is one of the few genuinely modifiable contributors to problems that can persist for years.

What to let go of

You do not need to "get it over with" on day one. You do not need to force anything. And the fact that the first attempt is frightening does not mean something has gone wrong — the NHS and RCOG both expect it to be uncomfortable and both are clear that the stitches will hold. What matters is not letting the delay turn into genuine constipation, because that is when the straining starts.
