Also called: Fecal incontinence; anal incontinence
Exercise is the main treatment
Strength
Loss of control over wind or stool - one of the most isolating symptoms there is, and one of the least often mentioned. It is usually a weak or poorly coordinated sphincter, most often after childbirth, and it responds well to training that almost nobody is offered.
How common: Around 8% of adults; up to 15% of older women; massively under-reported
What it is
Continence depends on the internal anal sphincter, which works involuntarily, the external sphincter and puborectalis, which are under voluntary control, and on the sensation that tells you something is arriving. Damage or weakness in any of these produces leakage.
The commonest cause in women is obstetric injury - a tear involving the sphincter, or nerve damage during delivery - and symptoms often appear years or decades later as age-related weakening removes the remaining margin. It is substantially under-reported: most people never tell anyone, including their doctor, which is why it goes untreated for years.
What it feels like
- Leaking wind without meaning to
- Staining or leakage of stool, particularly when it is loose
- Urgency - having to reach a toilet within minutes
- Planning every journey around toilets and, often, avoiding going out
- Wearing pads and telling nobody, which is the most common pattern
What causes it
Most people have more than one of these at once, and they feed each other. Read the
list looking for the two or three that sound like your week rather than for the one
true answer — the ones that describe you are the ones worth acting on.
- Obstetric sphincter injury
- A third or fourth degree tear during delivery damages the anal sphincter directly. Even repaired, function is often incomplete, and symptoms may only appear decades later as other margins are lost.
- Pudendal nerve damage
- Stretching of the nerve supply during a long second stage or instrumental delivery weakens the sphincter without any visible tear. It is a common and invisible cause.
- Age-related sphincter weakening
- Sphincter pressure falls with age like any other muscle. Someone with a compensated old injury reaches the point where the reserve runs out.
- Loose stool
- Continence for liquid is much harder than for solid. Anything causing loose stool - IBS, medication, dietary triggers, infection - can produce leakage in someone whose sphincter would cope otherwise.
- Constipation with overflow
- A hard stool blocking the rectum allows liquid to leak past it. It is a common cause in older adults and in children, and it is treated by relieving the constipation, not by strengthening anything.
- Previous anal surgery
- Surgery for haemorrhoids, fissures or fistulas can affect sphincter function, sometimes years later.
- Rectal prolapse and pelvic organ prolapse
- Both alter the anatomy the continence mechanism depends on and frequently coexist with the symptom.
- Neurological conditions
- Multiple sclerosis, spinal cord injury, diabetes-related neuropathy and stroke all impair sphincter control or the sensation that precedes it.
- Inflammatory bowel disease
- Urgency from active inflammation can overwhelm a normal sphincter, and long-standing disease can damage it.
- Never telling anyone
- Not a physical cause but the reason most cases go untreated. The embarrassment is enormous and the treatments are genuinely effective, which makes the silence particularly costly.
Who tends to get it
- Women who had a third or fourth degree tear, or an instrumental delivery
- Older adults, in whom sphincter pressure declines
- Anyone with loose stool from IBS, inflammatory bowel disease or medication
- People with constipation, where overflow is a common mechanism
- Anyone with a neurological condition or previous anal surgery
What makes it worse, and what settles it
Makes it worse
- Loose stool, which is much harder to hold than formed stool
- Constipation with overflow, which needs treating in the opposite direction
- Caffeine and other gut stimulants
- Not telling anyone, which is the main obstacle to effective treatment
- Avoiding going out, which is the consequence rather than a cause but shapes everything
Settles it
- Pelvic floor and anal sphincter training, which improves symptoms in a majority of people
- Biofeedback with a specialist physiotherapist, which is more effective than exercises alone
- Firming up stool consistency - fibre supplementation and, where appropriate, medication
- Treating constipation where overflow is the mechanism
- Telling a clinician, which is the step that unlocks every effective treatment
What actually helps
The short version: Weak or poorly coordinated anal sphincter and pelvic floor, often after obstetric injury
Strength work: Core: Pelvic Floor - pelvic floor and sphincter training, ideally with biofeedback; Core: Transverse Abdominis
Stretching: Hips: Adductors
Massage: Not primary
Also worth doing: Stool consistency management; bowel retraining; biofeedback improves results substantially
What the evidence says: Pelvic floor muscle training with biofeedback is first-line conservative treatment. Under-reported because people do not raise it - naming it in an app is itself useful.

Get it checked if…
New bowel incontinence with back pain or leg numbness is a cauda equina red flag; blood or sudden change needs colorectal review
And whatever the body part: chest pain or unusual breathlessness on
exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and
unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or
one calf that is swollen, warm and painful. Any of those, stop and get assessed.
How it usually goes
Pelvic floor and sphincter training with biofeedback improves symptoms substantially in a majority of people over three to six months, and further options - sacral nerve stimulation, surgical repair - exist for those who do not respond. The largest obstacle by far is that people do not mention it. Prevalence is far higher than reporting suggests, particularly in older women, and it is one of the most treatable symptoms that is routinely endured in silence.
Prevalence basis: Colorectal and continence surveys
Others the same routine covers
These share the Pelvic Floor & Core Recovery routine, so the work is the same. If one of them also
sounds like you, that is a reason to expect more from it, not less.
This is general information, not a diagnosis, and it cannot examine you.
If it matches you, use it to ask better questions of a clinician rather than to replace one.
