Postpartum fecal incontinence

How recovery typically progresses

Immediately after

First days

In the early days and weeks after birth, some looseness of stool or gas control is common while perineal tissue and nerves are tissue repair, and it's worth mentioning at your first postpartum contact rather than waiting for it to come up on its own.

Settling in

Early weeks

By around 6 weeks to a few months out, symptoms often ease as tissue repair continues, but research has found postpartum rates can actually peak around 6 weeks and dip by 6 months, so a symptom that hasn't improved by your postpartum visit is worth naming specifically rather than assuming more time alone will settle it.

Longer arc

Beyond six weeks

Further out, symptoms can persist or even reappear later; one study found rates climbing again by a year after birth, so this isn't only a first-weeks concern. Pelvic floor physical therapy and dietary adjustments remain reasonable options well beyond the initial recovery period.

What does the evidence show for postpartum fecal incontinence?

• Fecal incontinence, also called accidental bowel leakage, is defined as the accidental passing of bowel movements, including solid stools, liquid stools, or mucus, from the anus; this definition does not include gas on its own, which matters because some research on postpartum symptoms uses a broader definition that does include gas. 1
• Childbirth by vaginal delivery can injure the anal sphincters, and the chances of this kind of injury are greater when a baby is large, forceps or a vacuum were used to help deliver the baby, or an episiotomy was made in the vaginal area during birth. 2
• Overt sphincter damage from third- or fourth-degree vaginal tears resulting in symptomatic incontinence has been reported in up to 0.7% of all vaginal deliveries, but sphincter damage that shows up on imaging is far more common than that: among 79 first-time mothers with intact sphincters before delivery, 28 showed damage to one or both sphincter muscles afterward, most without producing symptoms. 3
• Named risk factors for sphincter injury include forceps delivery, being a first-time mother, a baby's birth weight over 4 kg, and an occiput-posterior baby position; notably, a posterolateral episiotomy does not protect against a sphincter tear, contrary to a common assumption. 3
• Initial approaches for milder symptoms include dietary changes, bowel retraining, and lifestyle measures; more involved options include posterior tibial nerve stimulation, anal irrigation, or surgical repair, though primary surgical repair has had disappointing long-term outcomes in the literature, with many patients needing additional procedures over time. 3
• In a study following 240 first-time mothers, fecal incontinence symptoms were reported by 1.3% at 20 weeks of pregnancy, rose to 6.4% at 6 weeks postpartum, fell to 1.8% at 6 months, and rose again to 5.3% at 1 year, showing that symptoms can fluctuate rather than steadily improve in a straight line. 4
• None of the symptomatic women in that same study had a known sphincter injury from delivery, and factors such as spontaneous pushing or doing Kegel exercises were not associated with fecal incontinence in that group; more broadly, reported postpartum rates across different studies range from about 3% to 29%, with the higher figures typically reflecting definitions that include gas incontinence and populations with more operative deliveries or sphincter lacerations. 4
• For symptoms linked to loose stool, commonly suggested dietary changes include cutting back on alcohol, caffeine, dairy products, fatty or greasy foods, certain fruits and other sources of fructose, spicy foods, and sugar alcohols like sorbitol and xylitol, alongside keeping a food diary since individual triggers vary; for symptoms linked to constipation, more fiber and fluids are the usual starting point instead. 5

When should I call my provider about postpartum fecal incontinence?

A hallmark sign that symptoms are coming from a rectovaginal fistula rather than ordinary postpartum muscle or nerve changes is stool or gas passing through the vagina itself, often together with a foul-smelling vaginal discharge; this points to an abnormal connection between the rectum and vagina, most commonly linked to a third- or fourth-degree tear during delivery, and needs referral to a specialist rather than home management alone. Fever, spreading redness, increasing pain, or a wound that appears to be opening at a perineal repair site also needs prompt evaluation rather than being assumed to be part of normal tissue repair. If you are ever unsure which side of the line you are on, make the call. Obstetric teams handle these check-ins as routine, not as overreacting.
