Bowel incontinence affects roughly 1 in 12 adults worldwide, and most cases improve significantly with the right combination of dietary changes, exercises, and behavioral strategies. The approach that works best depends on what’s causing the problem: weak sphincter muscles, nerve damage, stool consistency issues, or a combination of these. Here’s what actually helps, from the simplest changes to more advanced options.
Why Bowel Incontinence Happens
Your ability to hold stool depends on a surprisingly coordinated system. The rectum can store up to 300 mL of stool without increasing pressure, but beyond that, you feel the urge to go. The internal anal sphincter, which you don’t consciously control, is responsible for 80% to 85% of your resting anal tone. The external sphincter, which you do control, kicks in during sudden pressure like coughing or lifting. A sling-shaped muscle called the puborectalis wraps around the junction between the rectum and anus, creating an angle that acts as a physical barrier.
When any part of this system is disrupted, leakage can follow. Vaginal delivery is one of the most common causes, since it can damage both the sphincter muscles and the nerves that control them. Stroke, spinal cord injury, diabetes-related nerve damage, chronic constipation with overflow, and inflammatory bowel conditions are other frequent contributors. There are two main patterns: passive incontinence, where stool leaks without you even noticing (pointing to nerve or reflex problems), and urge incontinence, where you feel the urge but can’t get to the bathroom in time (pointing to muscle weakness or reduced rectal capacity). Knowing which type you experience helps guide treatment.
Adjust Your Diet to Firm Up Stool
Loose stool is harder to hold than formed stool, so one of the fastest ways to reduce episodes is to change what you eat. Soluble fiber is the key ingredient here. It absorbs liquid in the gut and forms a gel, which thickens stool and slows transit time. Good sources include oats, bananas, applesauce, and white rice. Fiber supplements like psyllium (Metamucil) or methylcellulose (Citrucel) can also help. In clinical trials, providing about 15 to 17 grams per day of supplemental fiber brought participants close to the recommended 25 to 30 grams daily, and this was enough to meaningfully improve stool consistency.
Increase fiber gradually, because adding too much at once causes gas and bloating. Drink plenty of water alongside it, since fiber needs fluid to work properly.
At the same time, cut back on things that loosen stool or speed up the gut. Cleveland Clinic’s dietary guidelines for fecal incontinence specifically flag these triggers:
- Caffeine and alcohol, which stimulate the gut and can loosen stool
- Sugary foods like candy, cakes, cookies, regular soda, jam, syrup, ice cream, and sorbet
- Cruciferous vegetables like broccoli, cabbage, and cauliflower, which increase gas
- Sugar-containing nutritional supplements
You don’t have to eliminate everything permanently. Start by cutting the biggest offenders for two to three weeks, then reintroduce items one at a time to identify your personal triggers.
Strengthen the Pelvic Floor
Pelvic floor muscle training is one of the most effective conservative treatments for bowel incontinence, with studies reporting success rates of 50% to 80%. A systematic review of nonrandomized trials found that 49% of people were fully cured and 72% were either cured or significantly improved after pelvic floor rehabilitation.
The exercises themselves are variations of Kegel contractions, but focused on the anal sphincter rather than just the front of the pelvic floor. There are three main types to practice:
- Maximal sustained contractions: Squeeze the sphincter as hard as you can and hold for 5 to 10 seconds. This builds strength for urgent situations.
- Submaximal sustained contractions: Squeeze at about half effort and hold for 10 to 20 seconds. This builds endurance for daily resting tone.
- Quick-flick contractions: Rapidly squeeze and release in short bursts. This trains your muscles to react fast when you cough, sneeze, or stand up suddenly.
The challenge is making sure you’re actually squeezing the right muscles. Many people bear down instead of lifting up, which makes things worse. A pelvic floor physical therapist can use biofeedback, a technique where sensors placed near the anus display your muscle activity on a screen in real time, so you can see exactly when you’re contracting correctly. If you can access a specialist, biofeedback-guided training tends to produce better results than verbal instruction alone. Aim for three sessions per day, and expect to see improvement over 8 to 12 weeks of consistent practice.
Use Bowel Retraining
Bowel retraining teaches your body to have predictable, complete bowel movements at a set time each day, which reduces the chance of unexpected leakage later. The core principle is simple: your gut is most active 20 to 40 minutes after eating, thanks to a natural reflex triggered by food entering the stomach. Use that window.
Pick a consistent time each day, ideally after a meal, and sit on the toilet for up to 20 minutes. Lean forward slightly to increase abdominal pressure, and consider using a footstool to elevate your knees above your hips. This position straightens the anorectal angle and makes emptying easier. If you don’t have a bowel movement within 20 minutes, you can try digital stimulation: insert a lubricated finger into the anus and move it gently in a circle until the sphincter relaxes, then attempt again.
Consistency matters more than anything else with this approach. It can take several weeks for the bowel to adapt to the new schedule, but once it does, many people find their episodes drop significantly because the rectum is emptying more completely at a predictable time.
Medications That Can Help
If dietary changes alone don’t firm up your stool enough, over-the-counter anti-diarrheal medications can make a real difference. Loperamide (Imodium A-D) slows gut movement and increases sphincter tone, making it easier to hold stool. It’s often the first medication tried for bowel incontinence associated with loose or frequent stools.
On the other end, if chronic constipation is causing overflow incontinence (where liquid stool leaks around a hard blockage), gentle laxatives like polyethylene glycol (MiraLAX) or magnesium hydroxide can help clear the rectum so it functions normally again. Fiber supplements serve double duty here, both firming loose stool and softening hard stool to promote more complete emptying.
Protect Your Skin
Repeated contact with stool breaks down skin quickly, causing a condition called incontinence-associated dermatitis: redness, burning, rawness, and sometimes open sores. Preventing this matters both for comfort and for avoiding infections.
Skip regular soap and water for cleaning. Studies consistently show that perineal skin cleansers designed for incontinence care are gentler and more effective at preventing skin breakdown. After cleaning, apply a barrier product. Zinc oxide creams (like Sudocrem) provide a thick physical barrier. No-sting barrier films are thinner and reduce skin stripping better than petroleum-based ointments. Dimethicone-based wipes offer another protective option that was shown in one study to significantly reduce pressure ulcer rates in incontinent patients. The combination of a gentle cleanser plus a skin protectant outperformed either one alone in multiple studies.
Sacral Nerve Stimulation
When conservative treatments aren’t enough, sacral nerve stimulation is the most established next step. A small device, similar to a pacemaker, is implanted near the tailbone and sends mild electrical pulses to the nerves that control the sphincter, pelvic floor, and lower bowel. The exact mechanism isn’t fully understood, but the stimulation appears to improve both muscle function and rectal sensation.
The process starts with a temporary trial lasting about two weeks. If your symptoms improve by at least 50% during the trial, you’re a candidate for permanent implantation. In published data, about 56% to 80% of patients who undergo temporary stimulation go on to get a permanent device. Among those with permanent implants, 78% reported continued improvement at their most recent follow-up. This option is typically reserved for people who have at least one episode per week and haven’t responded to dietary changes, exercises, and medications.
Surgical Repair
Surgery is generally a last resort, reserved for people with a clearly identified structural problem that hasn’t responded to anything else. Sphincteroplasty, where a torn or damaged sphincter muscle is directly repaired, can help when the external sphincter has been disrupted by childbirth injury or trauma. However, the internal sphincter is not repairable with direct surgery.
For internal sphincter weakness, injectable bulking agents offer a less invasive alternative. These are injected around the anal canal to add volume and improve the seal. The procedure is quick and has minimal recovery time, though long-term outcomes are still being evaluated and head-to-head comparisons with other surgical options remain limited. More extensive procedures like artificial sphincter implantation exist but carry significant complication risks and are reserved for severe cases where other interventions have failed.
Combining Approaches for Best Results
Most people see the best improvement by layering several strategies together rather than relying on any single one. A typical starting plan combines dietary adjustments to improve stool consistency, pelvic floor exercises to strengthen the muscles, and bowel retraining to establish a predictable schedule. If stool remains too loose, adding a fiber supplement or loperamide can fill the gap. If progress stalls after 8 to 12 weeks of consistent effort, biofeedback-guided pelvic floor therapy or sacral nerve stimulation become reasonable next options. The important thing to know is that the majority of people with bowel incontinence see meaningful improvement with treatment, and many achieve full resolution.
