What is Faecal Incontinence?

Faecal incontinence is a challenging and often distressing condition that occurs when you are unable to fully control your bowel movements. In simple terms, it means you may not make it to the toilet in time, or you may not even be aware that you need to go until it’s too late.

This loss of control can lead to accidental leakage of stools, which may vary from very mild to more severe. For some people, it may just be a small leak when passing wind, sneezing, or coughing. For others, it can involve unexpectedly losing a larger amount, or even an entire bowel movement. The impact can range from occasional accidents to frequent episodes, often affecting confidence, daily activities, and overall quality of life.

Why does Faecal Incontinence occur?

Maintaining control over your bowel movements is a complex process that relies on the coordinated function of the nervous system, rectum, and anus. When any part of this system is disrupted, faecal incontinence can occur. That’s why identifying the underlying cause is such an important step in finding the right treatment.

Some of the most common causes of faecal incontinence include:
Anal sphincter damage – often linked to a severe tear during childbirth or trauma.
Weak pelvic floor muscles, which provide essential support for bowel control.
Previous surgeries, such as rectal, anal, prostate, or gynaecological procedures, that may affect bowel function.
Chronic constipation, which can stretch and weaken the anus over time.
Stool build-up in the rectum, leading to overflow leakage.
Overuse of laxatives, which can disrupt normal bowel control.
Small intestinal bacterial overgrowth (SIBO), which may cause diarrhoea and urgency.
Irritable bowel syndrome (IBS), especially when diarrhoea-predominant.
Stress and anxiety, which can worsen symptoms and bowel urgency.
By understanding the cause—whether structural, functional, or lifestyle-related—patients and healthcare professionals can work together to develop the most effective management plan.

Faecal Incontinence Diagnosis

Faecal incontinence can develop for many different reasons, from relatively minor issues to more complex conditions. Because the causes can vary so widely, it’s essential to identify what’s happening in your body so that the right treatment can be put in place.

To get a clearer picture, doctors may recommend one or more of the following tests:

Endoanal ultrasound – uses sound waves to create images of the anal muscles and surrounding tissues, helping to identify any damage or weakness.
Anorectal manometry – measures the strength and coordination of the muscles in the rectum and anus.
Pudendal nerve function test – checks whether the nerves in the pelvic floor that control bowel function are working properly.
Whole-gut transit study – a non-invasive test that tracks how long it takes food and waste to move through your digestive system.
Defaecography – an imaging test that looks at how your rectum and anus function during a bowel movement.
Carbohydrate malabsorption breath test – helps detect intolerances to certain sugars, such as lactose or fructose, which can cause diarrhoea and urgency.
Small intestinal bacterial overgrowth (SIBO) breath test – identifies whether excess bacteria in the small intestine may be contributing to symptoms.
By running these tests, healthcare professionals can determine the underlying cause of faecal incontinence and create a tailored plan to improve bowel control and quality of life.

Frequently asked questions

Everything you need to know about the product and billing.
What is faecal incontinence?
Faecal incontinence is the inability to control bowel movements, leading to accidental leakage of stool. This can range from small leaks when passing wind to a complete loss of bowel control.
What are the main causes of faecal incontinence?
Causes can include muscle or nerve damage (for example, after childbirth or surgery), a weak pelvic floor, chronic constipation, diarrhoea, irritable bowel syndrome (IBS), or conditions like small intestinal bacterial overgrowth (SIBO). Stress and anxiety can also worsen symptoms.
Who is most at risk of developing faecal incontinence?
It can affect anyone, but it is more common in older adults, women who have given birth, people with long-term digestive issues, and those who have had rectal, anal, or pelvic surgery.
Is faecal incontinence the same as diarrhoea?
No. Diarrhoea can make faecal incontinence worse, but they are not the same. Faecal incontinence refers specifically to the loss of control over bowel movements, regardless of stool consistency.
How is faecal incontinence diagnosed?
Diagnosis usually involves a detailed medical history, physical examination, and specialised tests such as anorectal manometry, endoanal ultrasound, or gut transit studies to assess muscle, nerve, and bowel function.
Can faecal incontinence be treated?
Yes. Treatment depends on the cause and may include dietary changes, pelvic floor exercises, bowel training, medication, biofeedback therapy, or in some cases, surgery. Many people find their symptoms improve significantly with the right approach.
Are there lifestyle changes that can help manage faecal incontinence?
Yes. Eating a balanced diet, managing constipation or diarrhoea, doing pelvic floor exercises, and keeping a bowel diary can all help. Reducing caffeine, alcohol, and foods that trigger diarrhoea may also make symptoms easier to control.
Is faecal incontinence something to be embarrassed about?
While it can feel embarrassing, faecal incontinence is more common than many people realise. Millions of people live with the condition, and seeking medical advice is the first step towards finding effective treatment and improving quality of life.
