Bowel Incontinence and Crohn's Disease: How to Cope

Bowel incontinence affects roughly a third of people with Crohn's disease, it happens in remission as well as in flares, and the biggest barrier to help is that almost nobody is asked about it directly.

If you have had an accident, or spent a bus ride bargaining with your own body, you are not an unlucky outlier. Bowel incontinence in Crohn's disease is one of the most common symptoms in IBD and one of the least discussed. Many of us have carried it quietly for years, assuming it was a private failure rather than a recognised part of the disease.

Key Takeaways

• A 2025 systematic review of 15 studies and 7,232 patients with Crohn's disease found a pooled fecal incontinence prevalence of 34.8 percent, though heterogeneity was very high (1)
• Across IBD, reported prevalence ranges from 12.7 percent to 76 percent, depending almost entirely on how incontinence is defined and who was studied (2)
• When clinicians asked face to face, 63 percent of 1,336 UK patients reported incontinence, versus 56 percent who answered the same questions on paper (3)
• Only 38.7 percent of those patients said they were interested in receiving help, which suggests many people have quietly concluded nothing can be done (3)
• Pelvic floor muscle training improved incontinence in 20 of 25 patients across 7 studies, but those studies were small and rated poor to fair in quality (4)
• Crohn's and Colitis UK says bowel incontinence and urgency affect up to 7 in every 10 people with Crohn's or Colitis, including during remission (5)

How Common Bowel Incontinence Actually Is

Bowel incontinence in Crohn's disease is common enough that a reader who has had accidents is in the majority, not the minority. A 2025 systematic review and meta-analysis pooling 15 prevalence studies across 7,232 patients with Crohn's disease found a fecal incontinence prevalence of 34.8 percent, with a 95 percent confidence interval of 24.0 to 46.5 percent (1). Roughly one in three.

Why the numbers vary so widely

That figure comes with a caveat. Heterogeneity was very high, with an I-squared of 98.9 percent, meaning the included studies disagreed enormously (1). Across IBD, a review of 18 studies covering 5,924 participants reported incontinence in anywhere from 12.7 percent to 76 percent of people (2). That is a definitional problem, not sloppy research: one study counts any staining of underwear, another only full loss of solid stool, and populations range from active flares to remission clinics.

Crohn's and Colitis UK tells patients that bowel incontinence and urgency affect up to 7 in every 10 people with Crohn's or Colitis at some point, and that it happens in remission as well as in flares (5). An accident does not mean your treatment has stopped working.

Why Crohn's Disease Takes Away Bowel Control

Continence depends on several systems, and Crohn's can disrupt all of them. Holding stool needs two muscular rings, the internal anal sphincter (automatic) and the external anal sphincter (which you can consciously squeeze), supported by the pelvic floor muscles and by nerves that signal something is arriving (5).

Stool consistency, sphincters and nerves

The most underrated factor is stool consistency. Liquid stool is dramatically harder to hold than formed stool, so anything that firms things up tends to improve control. In the broader IBD literature, the factors associated with incontinence include disease activity, loose stool, female sex, childbirth, previous surgery, and anal sphincter weakness or fatigability (2).

Anxiety and depression are associated with incontinence too (2). Those studies are cross-sectional, so causation cannot be inferred in either direction. Living with accidents can reasonably make anyone anxious, and anxiety can sharpen the urgency signal.

When perianal disease or surgery is the cause

In Crohn's specifically, the associated factors include perianal disease, prior anoperineal surgery, liquid stool, fecal urgency and age (1). Perianal Crohn's can damage the sphincter complex directly, and the surgery used to treat it can leave the muscles weaker. If that describes your history, our guide to perianal fistulas in Crohn's and Colitis covers the anatomy in more detail. The cause matters, because it points toward which treatment is likely to help.

The Silence Problem: Nobody Asks and Nobody Tells

The most striking finding in this field is not about anatomy. It is about conversation. The literature describes fecal incontinence in IBD as underreported and as negatively affecting quality of life (2), and one study measured how much the asking matters.

What a UK study of 1,336 patients found

Researchers surveyed 1,336 UK patients with IBD using the same questions delivered two ways. When a clinician asked face to face, 63 percent reported incontinence. When patients completed the identical questions themselves, 56 percent did (p = 0.012) (3). Those with Crohn's disease, higher disease activity, and ages 51 to 60 were more likely to report it (3).

Then comes the finding that should change how we approach appointments: only 38.7 percent of respondents said they were interested in receiving help (3). Fewer than four in ten, which is hard to read as anything but quiet resignation.

Because being asked directly is what surfaces the problem, it helps to walk in with the words ready: "I want to talk about bowel control. I have had accidents, and I would like to know what can be done." You do not owe anyone a detailed account.

What Actually Helps, and How Strong the Evidence Is

Several treatments for fecal incontinence in IBD show promise, and the evidence behind most of them is thin. Both halves of that sentence matter.

Pelvic floor muscle training and biofeedback

A systematic review of pelvic floor muscle training in quiescent IBD found incontinence improved in 20 of 25 patients, and evacuation difficulty in 51 of 76, across 7 studies (4). The training itself is low risk, non-drug and widely available through physiotherapy.

The same review lists its weaknesses plainly, and so should we: small numbers, poor to fair methodological quality, no blinded outcome assessment, no intention-to-treat analysis, and almost no long-term follow-up (4). It also found that training before stoma closure did not significantly reduce incontinence afterwards (4).

Nerve stimulation and surgery

Small Crohn's series report benefit from posterior tibial nerve stimulation and sacral nerve stimulation, and from anti-TNF therapy combined with surgical closure, all in very small numbers (1). Across IBD, intervention studies of sphincter repair and nerve stimulation totalled just 34 participants and were uncontrolled (2). These are options a specialist may raise in specific situations, not routine care.

Treating the inflammation first

Because disease activity and loose stool are both associated with incontinence (1, 2), getting inflammation under control is the foundation everything else sits on. If your Crohn's is active, your doctor may recommend reviewing your current therapy before adding anything else.

Living With It: Dignity, Daily Life and Practical Coping

In our community, the people who cope best are usually not those with the mildest disease. They are the ones who have built systems.

Going out, working and travelling

Toilet mapping comes first: know where the facilities are on your regular routes before you need them. Keep a change of underwear and trousers, wipes and a sealable bag in a day bag or at your desk. Many of us find that having the kit removes much of the dread. As we explored in our guide to restroom anxiety in Crohn's disease, the fear of being caught without a toilet becomes its own problem.

Know your access rights too. In parts of the United States, Ally's Law and the Restroom Access Act give people with IBD the right to use employee-only facilities in certain businesses. Rights and services vary by country, so ask your IBD team what exists where you live.

Skin care and products

Repeated contact with stool irritates skin quickly, and sore skin makes everything worse. Barrier creams and continence products protect skin and dignity rather than marking defeat, and Crohn's and Colitis UK itself suggests considering them (5).

Partners and intimacy

Telling a partner is usually less catastrophic than the version in your head. A short, factual explanation works better than an apology: this is a symptom of the disease, it is common, here is what helps. A manager needs to know what adjustment you need, not your medical history. Accidents also reshape how you see your own body, which our article on self-image and body confidence addresses directly. And urgency on its own, without accidents, is still worth raising with your IBD team.

When to Push for a Referral

Some symptoms warrant prompt review rather than a routine appointment: new or rapidly worsening incontinence, bleeding, or perianal pain and discharge that could point to a fistula or abscess.

For the longer-term problem, ask for an IBD nurse specialist, a colorectal specialist, or a pelvic floor trained physiotherapist. A continence assessment is less daunting than people expect: a conversation about symptoms and stool pattern, an examination, and sometimes tests of sphincter strength. Screening is recommended in routine IBD practice (3), so raising it is not an imposition.

Resources Worth Exploring

These are everyday products people with IBD use to protect skin and reduce anxiety about leaks. They manage the consequences and do not treat the disease, so they belong alongside a continence assessment, not instead of one.

• TENA Sensitive Care Incontinence Pads, Ultimate Absorbency - disposable pads for heavier leakage, useful on travel days and overnight. This is not a medical recommendation. Discuss with your healthcare provider before trying any new product or protocol.
• Carer Washable Leakproof Incontinence Underwear, 3 Pack - reusable absorbent underwear closer to ordinary briefs, which many people prefer for daily wear. This is not a medical recommendation. Discuss with your healthcare provider before trying any new product or protocol.
• Calmoseptine Moisture Barrier Ointment, 2.5 oz - a zinc oxide barrier ointment used to protect skin repeatedly exposed to stool. Ask a continence nurse if your skin is already broken. This is not a medical recommendation. Discuss with your healthcare provider before trying any new product or protocol.

Frequently Asked Questions

Is bowel incontinence a sign my Crohn's is getting worse?

Not necessarily. Disease activity and loose stool are associated with incontinence (1, 2), so a flare can trigger it. But Crohn's and Colitis UK is clear that it also occurs during remission (5), often from sphincter damage or nerve changes that persist after inflammation settles. New or worsening incontinence is still worth reporting promptly.

How common is fecal incontinence in Crohn's disease?

A 2025 meta-analysis of 15 studies covering 7,232 patients found a pooled prevalence of 34.8 percent, roughly one in three (1). Across IBD, individual studies report anywhere from 12.7 percent to 76 percent, because definitions and populations differ so much (2). Patient organisations describe it as affecting up to 7 in 10 people at some point (5).

Do pelvic floor exercises actually work for IBD?

The evidence is encouraging but limited. A systematic review in quiescent IBD found incontinence improved in 20 of 25 patients across 7 studies, though those studies were small and rated poor to fair in quality, with almost no long-term follow-up (4). The same review found no significant benefit before stoma closure (4). Worth trying with a trained physiotherapist.

Why has my doctor never asked me about this?

Fecal incontinence is described in the literature as underreported (2), and the asking matters: 63 percent of patients reported it when a clinician asked face to face, versus 56 percent completing the same survey alone (3). Screening is recommended in routine practice (3) but still frequently skipped, so you may need to raise it first.

Can surgery or nerve stimulation fix bowel incontinence?

Sometimes, in selected cases, but the evidence base is very thin. Small Crohn's series report benefit from posterior tibial and sacral nerve stimulation, and from anti-TNF therapy with surgical closure, all in very small numbers (1). Across IBD, sphincter repair and nerve stimulation studies included only 34 participants and were uncontrolled (2).

Are continence products and assessments covered by insurance?

This varies by country and insurer. Some health systems provide continence products and specialist assessment free or at low cost through a continence service, while elsewhere they are an out-of-pocket purchase. Your IBD nurse or a local IBD charity is usually the fastest route to finding out what is available where you live.

What should I ask my doctor about bowel incontinence?

Useful questions: could my current disease activity be driving this, is my sphincter likely damaged from previous surgery or perianal disease, can you refer me to a pelvic floor physiotherapist or continence service, would anything help firm up my stool, and are there red flags to watch for.
