Fecal Incontinence: Symptoms, Causes, Diagnosis & Treatment

Written by Medicover Team and Medically Reviewed by Dr Raosaheb Rathod , Gastroenterologists Medical



Fecal incontinence is the inability to control bowel movements, leading to the accidental leakage of stool or gas. It can result from muscle or nerve damage, chronic diarrhea, constipation, childbirth, or other underlying medical conditions. Early diagnosis and appropriate treatment help improve bowel control, reduce symptoms, prevent complications, and enhance quality of life.


What are the Symptoms of Fecal Incontinence?

The symptoms of fecal incontinence can differ among individuals, but common manifestations include:

  • Sudden urge incontinence to defecate that cannot be controlled
  • Leaking stool during physical activities or movements
  • Inability to reach the toilet in time
  • Diarrhea or constipation-related leakage
  • Occurrence of stool stains on underwear

These symptoms can significantly impact one's quality of life, leading to social embarrassment, isolation, and mental health challenges.


What Causes Fecal Incontinence?

Faecal incontinence can occur for a variety of reasons, often involving multiple contributing factors. Understanding these causes is essential for effective management and treatment.

Muscle or Nerve Damage

Damage to the anal sphincter muscles or the nerves that control them is one of the primary causes of fecal incontinence. This damage can result from childbirth, surgery, or trauma. Additionally, nerve damage related to diabetes or multiple sclerosis can contribute to bowel control issues.

Medical Conditions

Several medical conditions can exacerbate faecal incontinence:

  • Chronic Constipation: This can lead to faecal impaction, where hard stool gets stuck in the rectum, causing liquid stool to leak around it.
  • Diarrhea: Loose stools can be more challenging to control than solid stools, increasing the risk of incontinence.
  • Inflammatory Bowel Diseases (IBD): Conditions like Crohn's disease and ulcerative colitis cause inflammation of the digestive tract, affecting stool consistency and control.

Age-Related Changes

As individuals age, the muscles and nerves of the rectum and anus may weaken, leading to decreased control over bowel movements. While not all elderly individuals experience fecal incontinence, age-related changes in bowel function can increase susceptibility.

Other Contributing Factors

Other factors include:

  • Pelvic Floor Dysfunction: Weakening or injury to the pelvic floor muscles can lead to fecal incontinence.
  • Surgery and Radiation Therapy: Procedures involving the pelvic organs can damage nerves and muscles, affecting bowel control.
  • Prolonged Use of Laxatives: Overuse can weaken bowel muscles, leading to dependency and eventual incontinence.

When to See a Doctor for Fecal Incontinence?

Fecal incontinence can affect daily activities and emotional well-being. Medical evaluation by a gastroenterologist medical is important if symptoms persist, worsen, or interfere with routine life, especially when associated with underlying digestive or neurological conditions.

You should see a doctor if you have:

  • Frequent or uncontrolled bowel leakage
  • Difficulty reaching the toilet in time
  • Persistent diarrhea or constipation

Get medical help immediately if:

  • Severe abdominal pain or swelling
  • Sudden loss of bowel control with weakness
  • Signs of infection or dehydration

These could be signs of a serious complication like a Fecal Incontinence, which needs urgent care.

How is Fecal Incontinence Diagnosed?

Diagnosis involves identifying the underlying cause through a detailed medical history, physical examination, and specialized tests of bowel and pelvic floor function.

  • Medical history and assessment of bowel habits.
  • Physical and digital rectal examination.
  • Anal manometry to measure sphincter muscle strength.
  • Endoanal ultrasound to evaluate sphincter damage.
  • MRI of the pelvic floor when indicated.
  • Colonoscopy or sigmoidoscopy to examine the rectum and colon.
  • Nerve function testing in selected cases.

What are the Treatment Options for Fecal Incontinence?

Effective management of fecal incontinence often requires a multifaceted approach, combining lifestyle modifications, medical treatments, and, in some cases, surgical interventions.

Lifestyle and Dietary Modifications

Making specific lifestyle and dietary changes can help manage symptoms and improve bowel control:

  • Dietary Adjustments: Consuming a diet high in fiber can help regulate bowel movements and improve stool consistency. Identifying and avoiding trigger foods, such as caffeine or artificial sweeteners, is also beneficial.
  • Scheduled Toilet Use: Establishing a regular toileting schedule can help train the bowel to evacuate at certain times.
  • Pelvic Floor Exercises: Strengthening pelvic floor muscles through exercises such as Kegel exercises can improve sphincter control.

Medications for Fecal Incontinence

Several medications can assist in managing fecal incontinence, depending on the underlying cause:

  • Anti-diarrheal Medications: Drugs like loperamide can help solidify stool and reduce urgency.
  • Laxatives and Stool Softeners: For those with constipation-related incontinence, these can help regulate bowel movements.
  • Topical Treatments: Creams and ointments can help protect the skin around the anus from irritation caused by leakage.

Advanced Therapies and Surgical Options

In cases where conservative measures are insufficient, more advanced therapies may be considered:

  • Biofeedback Therapy: This technique involves using electronic devices to help patients gain better control over their pelvic muscles.
  • Sacral Nerve Stimulation: A device is implanted to stimulate the nerves, control the bowel, and improve sphincter function.
  • Surgical Interventions: Surgery may be necessary to repair damaged muscles or nerves or to create a colostomy in severe cases.
