Dyschezia literally means difficulty pooping. It describes a condition where you can’t have a bowel movement without significant straining, pain, or a feeling that stool is stuck and won’t come out. The term applies to both infants and adults, though the underlying reasons and outlook differ considerably between the two groups.
How Dyschezia Differs From Constipation
Many people assume dyschezia and constipation are the same thing, but they are distinct problems. Constipation typically involves infrequent bowel movements or hard stools, often linked to slow movement of stool through the colon. Dyschezia is an outlet problem: stool reaches the rectum but your body struggles to push it out. You may actually have soft stool and still not be able to pass it easily. The distinction matters because standard laxatives, which work by softening stool or speeding up the colon, often don’t solve dyschezia. The issue isn’t what’s happening upstream. It’s what’s happening at the exit.
What Causes It in Adults
A normal bowel movement requires two things to happen at the same time: your abdominal muscles push down to create pressure, and your pelvic floor muscles relax to open the passage. In most adults with dyschezia, these two actions are out of sync. Instead of relaxing during a push, the pelvic floor muscles tighten or fail to release. This is sometimes called dyssynergic defecation or pelvic floor dyssynergia.
Research shows this discoordination takes several forms. Some people generate too little pushing force. Others involuntarily clench the anal sphincter at exactly the wrong moment. Many have a combination of both problems. On top of that, 50 to 60 percent of people with dyssynergic defecation also have impaired rectal sensation, meaning the nerves that signal “it’s time to go” don’t fire as strongly as they should.
Structural issues can also contribute. Conditions like a rectocele (a bulge of the rectal wall), internal rectal prolapse, or scar tissue from surgery can physically block stool from exiting even when the muscles are coordinating properly.
Infant Dyschezia
Infant dyschezia looks alarming but is almost always harmless. It typically appears in the first six months of life. A baby will strain, cry, and turn red in the face for at least 10 minutes before eventually passing a soft stool, or sometimes not passing one at all. Parents often assume their baby is constipated, but the stool itself is normal in consistency.
The explanation is straightforward: newborns haven’t yet learned to coordinate the two muscle groups needed for a bowel movement. They know how to increase abdominal pressure (that’s the crying), but they haven’t figured out how to relax their pelvic floor at the same time. Each attempt is essentially trial and error. The baby cries and pushes until, by chance, the pelvic floor relaxes and stool passes through.
Infant dyschezia rarely lasts more than a week or two and resolves on its own as the baby’s nervous system matures. It has no connection to developing constipation later in childhood. Studies tracking children with infant dyschezia found no causal relationship between the two conditions, so they are considered separate problems entirely. No treatment, laxatives, or rectal stimulation is needed.
How It’s Diagnosed in Adults
Because dyschezia involves muscle coordination rather than stool consistency, diagnosing it requires tests that measure how your muscles behave during a bowel movement. The two most common are anorectal manometry and the balloon expulsion test.
Anorectal manometry uses a small, flexible catheter placed in the rectum to measure the pressures your muscles generate when you squeeze and push. It reveals whether your anal sphincter is clenching when it should be relaxing, or whether your pushing force is too weak.
The balloon expulsion test is simpler. A small balloon is inflated in your rectum, and you’re asked to push it out. Most people can do this in about 12 to 13 seconds. The upper limit of normal is generally one minute, though some researchers use a cutoff as short as 26 seconds. If you can’t expel the balloon within that window, it suggests an outlet-type problem.
Biofeedback Therapy
The most effective treatment for dyschezia caused by muscle discoordination is biofeedback therapy. This is a form of physical therapy that retrains your pelvic floor muscles to work in the right sequence. During a session, a small sensor is placed in the rectum, and a screen displays your muscle activity in real time. You practice contracting and relaxing your pelvic floor while watching the feedback, gradually learning to relax those muscles on command during a simulated push.
Sessions typically last about an hour and are done every other day for the first two weeks, then two to three times per week after that. You’re also asked to practice the squeeze-and-relax technique at home for about 20 minutes at a time, several days a week. The training focuses on two skills: bracing your abdominal wall to generate pushing force and simultaneously releasing the pelvic floor.
Success rates are encouraging. One study of 171 patients found that biofeedback was effective in about 81 percent of cases, with nearly three-quarters of patients rating the improvement as very significant. Across the broader research, improvement rates range from 44 to 100 percent depending on the study and how success is measured. Biofeedback works because the core problem is a learned (or never-learned) motor pattern, and the muscles themselves are healthy. They just need retraining.
When Biofeedback Isn’t Enough
For people who don’t respond to biofeedback or pelvic floor physical therapy, other options exist. Botulinum toxin injections into the pelvic floor muscles can help by temporarily relaxing muscles that won’t release on their own. In studies of women with pelvic floor muscle pain and associated dyschezia, injections produced significant improvement in dyschezia symptoms within 4 to 11 weeks. The relief isn’t permanent, as the effects of the injection wear off over several months, but it can break a cycle of muscle tightness and allow physical therapy to become more effective.
Earlier surgical approaches that involved cutting part of the anal sphincter muscle were largely unsuccessful, helping only 10 to 30 percent of patients. This makes sense given what we now know: the problem isn’t one rogue muscle but a failure of coordination among several muscle groups working together. Treating just one part of the system doesn’t fix the underlying timing problem.
Living With Dyschezia
If you’re dealing with chronic straining, pain during bowel movements, or a persistent sensation that stool is stuck, the most important thing to understand is that this is a coordination problem with a name and a treatment pathway. Many people spend years assuming they simply have stubborn constipation, cycling through fiber supplements and laxatives that never quite work. That frustration often has a specific explanation: the muscles responsible for releasing stool aren’t cooperating, and no amount of stool softening will fix a timing issue.
Keeping stool soft through adequate fiber and water intake still helps, because passing firm stool through a poorly coordinating pelvic floor is harder than passing soft stool. But the real gains come from addressing the muscle discoordination directly, most often through biofeedback or pelvic floor physical therapy.
