Bowel incontinence is more common than almost anyone assumes — affecting a meaningful percentage of adults, and considerably more among older people and women who have given birth. It is also the symptom people are least likely to disclose. Surveys consistently find that most affected people have never told a healthcare professional, and many have not told their partner.
That silence has a cost, because faecal incontinence responds well to conservative treatment. Specialist pelvic floor physiotherapy combining sphincter rehabilitation, biofeedback and stool-consistency management achieves significant improvement for the majority of patients — and it is recommended before surgical options are considered.
Jency Sudha works within the colorectal and pelvic floor team at the Royal London Hospital, where this is core clinical work rather than an occasional referral.
What counts as bowel incontinence
It is a spectrum, and the milder end is what most people experience and least often report. Any of these is worth assessing:
- Difficulty controlling wind — the most common and most under-reported symptom
- Urgency — needing to reach a toilet immediately, unable to defer
- Staining or soiling of underwear
- Leakage of loose stool, particularly when urgency strikes
- Leakage of formed stool
- Passive leakage — soiling without being aware of it
- Post-defaecation seepage — leakage shortly after opening your bowels
- Incomplete emptying — feeling you have not finished, then leaking later
Planning journeys around toilets, carrying spare underwear, avoiding eating before going out, or declining social events because of your bowels — these are all reasons to seek assessment, whatever the frequency of actual accidents.
Common causes
Obstetric sphincter injury
Third and fourth degree tears (OASI) damage the anal sphincter directly. Symptoms may appear immediately or emerge years later, often around menopause. See perineal tear recovery.
Occult sphincter injury
Sphincter damage that was not recognised at the time of birth is more common than the recorded tear rate suggests, and explains many cases presenting decades later.
Loose stool
A weak sphincter may cope perfectly with formed stool and fail entirely with loose stool. Stool consistency is frequently the decisive factor and one of the easiest to change.
Constipation with overflow
Counter-intuitively, a common cause. Retained hard stool causes liquid to seep past it. Treating the constipation resolves the incontinence.
Prolapse
Rectocele and rectal prolapse interfere with complete emptying and with sphincter mechanics. See prolapse physiotherapy.
Nerve-related causes
Prolonged straining, childbirth, diabetes, spinal problems and neurological conditions can affect the nerve supply to the sphincter and to rectal sensation.
Surgery and radiotherapy
Anal or rectal surgery, including haemorrhoid procedures and fistula repair, and pelvic radiotherapy can all affect continence.
Age-related change
Sphincter pressure and rectal compliance decline with age, which is why symptoms from an old injury often surface much later.
How it is treated
Conservative treatment is recommended first, and it is effective for most people. Treatment usually combines several strands.
Assessment
A detailed bowel history, a stool diary, and — with your consent — examination including assessment of anal sphincter resting tone, squeeze pressure and endurance, plus rectal sensation. This distinguishes a weak sphincter from poor sensation from a stool-consistency problem, which point to quite different treatments.
Stool consistency management
Often the single most effective intervention. The aim is a formed, soft stool that is easy to control — achieved through soluble fibre, fluid, dietary triggers, and where appropriate loperamide timed in advance of risky situations rather than taken reactively.
Anal sphincter rehabilitation
Targeted strengthening of the external anal sphincter and puborectalis, working on both maximum squeeze and — more importantly for continence — endurance, since the ability to hold for long enough to reach a toilet is what actually matters.
Biofeedback
Central to bowel rehabilitation. Many patients cannot tell whether they are contracting the correct muscle, particularly where sensation is altered. Visual feedback resolves that, and it is the modality with the best evidence in this condition. See biofeedback therapy.
Urgency deferral training
Progressively building the ability to hold on. Combines sphincter contraction, controlled breathing and positioning, then gradually extends the interval — the bowel equivalent of bladder retraining.
Rectal sensation retraining
Where sensation is blunted, structured retraining improves awareness of rectal filling so you register the signal earlier and have time to respond.
Defaecation mechanics
Positioning, breathing and avoiding straining, so the bowel empties completely. Incomplete emptying is a frequent cause of later seepage. See constipation physiotherapy.
What to expect from treatment
Most patients notice improvement within six to twelve weeks, with a full programme typically running three to six months. Improvement is usually incremental — better wind control first, then longer deferral time, then fewer episodes — rather than sudden.
Realistic goals matter. For some patients the outcome is complete continence. For others it is reliable control in everyday situations, freedom from constant toilet-mapping, and confidence to leave the house without planning around it. Both are life-changing, and the second is still a good result.
If conservative treatment does not achieve enough, that is useful information rather than a dead end — it supports onward referral to colorectal surgery for consideration of options such as sacral nerve stimulation, and your assessment findings go with you.
See your GP promptly for: bleeding from the bowel, unexplained weight loss, a persistent change in bowel habit lasting more than three weeks, or sudden loss of bowel control with numbness in the saddle area or leg weakness — the last of these needs emergency assessment.
Frequently Asked Questions
Is bowel incontinence common?
Considerably more common than people assume — affecting a meaningful percentage of adults, and more among older people and women who have given birth. It is also the least reported of all pelvic health symptoms: most affected people have never told a healthcare professional, which makes it seem far rarer than it is.
I can control stool but not wind. Is that worth treating?
Yes, and it is one of the most treatable presentations. Difficulty controlling wind usually reflects reduced anal sphincter strength or endurance, or altered rectal sensation, and it responds well to targeted sphincter rehabilitation with biofeedback. It is also an early sign worth acting on before it progresses.
Can physiotherapy really help bowel control?
Yes. Conservative treatment combining anal sphincter rehabilitation, biofeedback, urgency deferral training and stool-consistency management is recommended as first-line treatment ahead of surgery, and achieves significant improvement for the majority of patients. Biofeedback in particular has good supporting evidence in this condition.
My symptoms started decades after childbirth. Can it still be related?
Very possibly. Anal sphincter injury sustained during childbirth is often compensated for successfully for many years, then unmasked as sphincter pressure and rectal compliance decline with age or around menopause. Sphincter injury that was not identified at the time of birth is more common than recorded tear rates suggest, and this delayed presentation is a well-recognised pattern.
Will I need surgery?
Most people do not. Conservative treatment is recommended first and is effective for the majority. Where it does not achieve enough, options such as sacral nerve stimulation exist and are considered by a colorectal surgeon — and having completed physiotherapy strengthens rather than delays that pathway, because it establishes what conservative management has already achieved.
Do I have to have an examination?
No. Assessment of anal sphincter tone, squeeze strength, endurance and rectal sensation gives the most accurate picture and directly determines treatment, which is why it is offered. It is entirely optional, fully explained beforehand, and can be stopped at any point. Treatment can begin with history, stool diary and consistency management alone if you prefer.

You Are Not the Only One
Most people with these symptoms have never told anyone. It is common, it is treatable, and it will not surprise your physiotherapist.
