What causes bowel incontinence and what can actually help

Bowel incontinence—losing control of your bowels involuntarily—usually comes from one of a few treatable causes: weak pelvic floor muscles, nerve damage, chronic diarrhea, or a blockage from constipation. The good news is that most people see real improvement once a doctor identifies which one is happening. Treatment ranges from simple habit changes and exercises to medications, dietary shifts, or in some cases, procedures. The first step is always a conversation with your doctor, because what works depends entirely on why it's happening.

You are not alone in this. Bowel incontinence affects millions of adults, and doctors have straightforward ways to figure out the cause and build a plan. Many people regain control without surgery or long-term medication.

Key Takeaways

  • Your doctor will ask about your bowel habits, medical history, and medications, then may perform a physical exam or imaging test to find the cause.
  • Pelvic floor exercises (Kegel exercises) strengthen the muscles that hold stool, and work best when done consistently over weeks or months.
  • Dietary changes—adding fiber gradually, staying hydrated, and avoiding trigger foods—often reduce accidents without medication.
  • Bowel training (using the bathroom at set times each day) helps your body develop a predictable routine and can significantly reduce leakage.
  • If simple measures do not work, medications, biofeedback therapy, or procedures are available options your doctor can discuss.

How your doctor will figure out what is causing it

Your doctor will start by asking detailed questions: How often do accidents happen? Are they liquid or solid? Do you feel the urge beforehand or does it happen without warning? They will also ask about your medical history, recent surgeries, medications you take, and whether you have had other bowel or nerve problems. This conversation alone often points toward the cause.

Next comes a physical exam. Your doctor will feel your abdomen and may perform a digital rectal exam (inserting a gloved finger into the rectum to check muscle tone and sensation). They may also order tests: a colonoscopy to rule out blockages or disease, an ultrasound or MRI to look at muscle structure, or anorectal manometry (a thin tube that measures how well your anal sphincter muscles squeeze). These tests are not painful, though they can feel uncomfortable.

Once your doctor knows the cause, they can recommend the right treatment. This is why the exam matters—treating constipation looks completely different from treating nerve damage, even though both cause incontinence.

Pelvic floor exercises to strengthen the muscles that hold stool

Kegel exercises target the pelvic floor muscles, which wrap around your bowel and help you hold stool. If these muscles are weak, accidents happen. Strengthening them takes time but works for many people.

To do Kegels: Tighten the muscles you use to stop the flow of urine or stool (you can identify them by actually stopping mid-stream once, though do not do this regularly). Hold the squeeze for three to five seconds, then relax for three to five seconds. Start with 10 squeezes, three times a day. Over weeks, work up to holding for 10 seconds and doing 20 to 30 squeezes per session. The key is consistency—you need to do them most days for at least four to six weeks before you notice improvement.

Some people find it helpful to do Kegels at the same time each day (while brushing teeth, during a commute, or before bed). A physical therapist who specializes in pelvic floor therapy can watch you do them and make sure you are using the right muscles, which makes a real difference in results.

Dietary changes and bowel habits that reduce accidents

What you eat and drink directly affects your bowel control. If you have diarrhea or loose stools, your bowel is harder to control. If you are constipated, stool can back up and leak around a blockage. Both situations improve with the right diet.

Start by adding fiber gradually—too much too fast causes bloating and gas. Aim for 25 to 35 grams a day from sources like whole grains, beans, vegetables, and fruit. Drink at least six to eight glasses of water daily; dehydration makes stool hard and constipation worse. Limit foods that trigger loose stools for you personally (common culprits are caffeine, alcohol, fatty foods, and high-sugar items). Keep a simple food diary for a week to spot patterns.

Bowel training teaches your body to have bowel movements at predictable times. Pick a time each day when you normally have the urge (often 20 to 40 minutes after eating), sit on the toilet for 5 to 10 minutes, and try to go—even if nothing happens. Do this every day at the same time. Over weeks, your body learns the routine and accidents become less frequent. This works especially well for people whose incontinence follows a pattern.

Medications that can help control bowel movements

If diet and exercises are not enough, medications can help. The choice depends on your specific problem. For diarrhea or loose stools, your doctor may prescribe loperamide (Imodium) or diphenoxylate (Lomotil), which slow bowel movement and make stool firmer. For constipation, stool softeners or mild laxatives help prevent the backup that causes leakage.

Some medications you already take might be making incontinence worse—certain blood pressure drugs, antidepressants, and pain medications can affect bowel control. Talk to your doctor about whether any of your current medications could be contributing. Sometimes switching to a different drug in the same class solves the problem.

Medications work best alongside diet and exercise changes, not instead of them. Your doctor will start with the lowest dose and adjust based on how you respond.

When to consider biofeedback or other treatments

Biofeedback therapy uses sensors to show you in real time how your pelvic floor muscles are working. A therapist guides you through exercises while a screen displays your muscle activity, helping you learn to control them better. Studies show biofeedback works well, especially for people whose incontinence comes from weak muscles or poor coordination. Sessions usually happen once a week for 4 to 6 weeks.

If exercises, diet, and medication do not work after three to six months, your doctor may discuss other options. Sacral nerve stimulation uses a small device (similar to a pacemaker) to send electrical signals to the nerves that control bowel function. Sphincter replacement surgery is rare but available for people with severe muscle damage. These are last-resort treatments, but they do help some people regain control.

Your doctor will explain the pros and cons of each option, including recovery time and success rates for your specific situation.

Managing daily life while you work on improvement

While you are working through treatment, practical steps make daily life easier. Wear absorbent pads designed for bowel incontinence (they are different from urinary pads and more discreet). Keep a change of clothes and wipes in your bag or car. Use a waterproof mattress cover at night. These are not permanent solutions—they are tools that let you live normally while your body heals.

Incontinence can feel isolating, but talking to your doctor and a therapist (if anxiety or depression is part of the picture) helps. Many people improve significantly once treatment starts, and knowing what to expect makes the waiting period less stressful.

Frequently Asked Questions

How long does it take for pelvic floor exercises to work?

Most people notice improvement after four to six weeks of consistent daily exercises, though some take longer. Improvement continues for three to six months. The key is doing them nearly every day—skipping days slows progress. If you see no change after three months, ask your doctor whether you are doing them correctly or whether a different treatment might help.

Can bowel incontinence go away on its own?

It depends on the cause. Incontinence from temporary diarrhea or a medication side effect may resolve once the cause is treated. Incontinence from weak pelvic floor muscles or nerve damage usually requires active treatment—exercises, diet changes, or medication—to improve. Your doctor can tell you whether your situation is likely to improve without treatment.

What should I eat if I have bowel incontinence?

Focus on regular fiber (25 to 35 grams daily), plenty of water, and consistent meal times. Avoid foods that trigger loose stools for you personally—these vary by person but often include caffeine, alcohol, high-fat foods, and artificial sweeteners. Keep a food diary for a week to spot your personal triggers, then avoid them while you build control.

Is bowel incontinence a sign of a serious disease?

Bowel incontinence itself is not a disease—it is a symptom of something else. Most causes (weak muscles, constipation, medication side effects) are treatable and not serious. Rarely, it signals a condition like inflammatory bowel disease or nerve damage that needs attention. Your doctor will rule out serious causes during the exam and testing.

What if nothing seems to be working?

If diet, exercises, and medication have not helped after three to six months, tell your doctor. You may need different testing to find a cause you were missed, a different medication, or a referral to a colorectal specialist or pelvic floor therapist. Some people need a combination of treatments, and adjusting the plan based on your response is normal.
