Dyssynergic Defecation and Pelvic Floor Therapy for Constipation: What You Need to Know

by Valerie Polley | Feb 13, 2023 | 2 comments

Have you made changes to your diet but are still struggling to go? If so, you may have a condition called dyssynergic defecation. Dyssynergic defecation is a condition where your pelvic floor does not properly coordinate the nerves and muscles, making it difficult to have a bowel movement. 

Luckily, pelvic floor therapy for constipation is an effective method of treating dyssynergic defecation. To learn more about dyssynergic defecation and pelvic floor therapy for constipation, read on.

What is Dyssynergic Defecation?

The pelvic floor is a complex system of nerves and muscles located at the lower part of the abdomen. It supports the pelvic organs such as the bowel, uterus, and bladder. One of its most important functions is helping us have regular bowel movements.

To encourage a bowel movement, the muscles and nerves of the pelvic floor must move in a coordinated manner. With dyssynergic defecation, there is a problem with how the muscles and nerves in the pelvic floor function, and they do not relax properly to allow a bowel movement.  When stool isn’t passed regularly, it becomes hardened and can feel stuck in your bowels, making it more difficult to pass.

 

What are the Symptoms of Dyssynergic Defecation?

Symptoms of dyssynergic defecation are similar to those of severe constipation, and include:

  • Having fewer than three bowel movements per week
  • Excessive straining to have a bowel movement
  • Feelings of incomplete evacuation (like there is still some stool left in the rectum after you have a bowel movement).
  • Hard, painful stools
  • The need to use your fingers to remove the stool
  • Bloated stomach
  • Stomach pain
  • Anal pain

While it can feel embarrassing to discuss these symptoms with your healthcare provider, providing an honest report of your symptoms is important for helping receive a diagnosis and coming up with an effective treatment plan.

How Common is Dyssynergic Defecation?

According to the Cleveland Clinic, it’s estimated that 15% to 25% of all chronic constipation cases are caused by dyssynergic defecation. They also estimate that chronic constipation affects between 10% and 20% of people worldwide and is about twice as common in people assigned female at birth.

 

What Causes Dyssynergic Defecation?

In a study of 118 people with dyssynergic defecation, researchers found that about one-third of people developed it during childhood. Another one-third developed it after an event such as pregnancy, trauma, or back injury. As many as 40% of people with dyssynergic defecation developed it for unknown reasons.

Dyssynergic defecation is a functional bowel disorder, meaning that the exact cause is unknown.

 

How is Dyssynergic Defecation Diagnosed?

The first step in diagnosing dyssynergic defecation is excluding other underlying disorders. Slow passage of waste through the colon may exist in up to two-thirds of people with dyssynergic defecation, so a test to assess colonic transit can be beneficial.

Here are some other tests and procedures used to diagnose dyssynergic defecation:

 

Digital Rectal Examination

A digital rectal examination is a medical test during which your doctor will insert a gloved, lubricated finger into your rectum to check for any abnormalities.

During the test, you may be asked to “bear down” as if you’re trying to have a bowel movement. This will allow your doctor to feel how the muscles move. If the muscles are moving abnormally, it may indicate dyssynergic defecation.

 

Anorectal Manometry

An anorectal manometry test measures how well the rectum and anal sphincter work. During the test, a small, flexible tube called a catheter with a balloon on the end is inserted into the rectum through the anus.

As the balloon is gradually inflated, it mimics the feeling of stool in the rectum. A machine connected to the tube measures the contractions and relaxations of the rectum and anal sphincter. By assessing these contractions and relaxations, your doctor can determine whether there is a discoordination of your pelvic floor muscles.

 

Balloon Expulsion Test

During the balloon expulsion test, a small balloon filled with warm water is placed in the rectum. Once the balloon is placed, you will move to a private room and be asked to push the balloon out.

Normally, a person can push the balloon out of their rectum in under one minute. If someone has dyssynergic defecation, it will often take longer than one minute to push out the balloon.

 

Defecography

During defecography, X-rays are used to record moving images of barium (a semi-solid paste) as it passes through the rectum. The barium simulates the passing of a soft stool, and the test can provide valuable information about structural changes that may be responsible for constipation.

 

Pelvic Floor Therapy for Constipation      

Once you’ve received a diagnosis of dyssynergic defecation, it’s time to develop a treatment plan. The most common type of pelvic floor therapy for constipation is called biofeedback therapy or biofeedback training.

Biofeedback training teaches you how to properly engage and relax your pelvic floor muscles and is considered the best treatment for dyssynergic defecation. This technique, which can be completed by a trained pelvic floor physical therapist, is used to correct the coordination of the abdominal and pelvic muscles during evacuation and to improve the perception of stool in the rectum.

 

What to Expect During a Biofeedback Training Session

During a biofeedback training session, your pelvic floor physical therapist will insert a probe into your anal sphincter. They will then place sticky pads on your abdomen. This will allow them to detect the movement of the muscles as you simulate having a bowel movement.

As you simulate having a bowel movement, you will receive visual or verbal feedback about what the muscles in your abdominal wall and anal sphincter are doing during a bowel movement. The pelvic floor physical therapist will have you do breathing exercises and muscle strengthening and relaxation exercises. This is what retrains the movement and coordination of your pelvic floor muscles.

According to research, the best protocol for biofeedback therapy includes doing 30–60-minute sessions one to two weeks apart for four to six sessions. After this protocol is completed, reinforcement sessions should be completed at six weeks, three months, six months, and twelve months.

 

How to Find a Pelvic Floor Physical Therapist

The best way to find a pelvic floor physical therapist is to get a referral from another healthcare provider (such as your dietitian or family doctor) or by doing a Google search yourself.

Here are a few tips that can help you find a pelvic floor physical therapist:

  • Search “pelvic floor physical therapist near me” to find therapists in your area.
  • Look at prospective clinics’ websites. This will often answer commonly asked questions, explain what to expect at your first visit, and provide information about the therapist’s credentials and experience.
  • If you have questions that are not answered by the clinic’s website, reach out to the clinic by phone or email. They should be able to put you in touch with a therapist who can answer your questions.
  • Find out if pelvic floor physical therapy is covered by your insurance provider.
  • Don’t be afraid to “shop around.” Pelvic floor physical therapy is intimate care, and it’s important that you find a provider that makes you feel comfortable.

 

Final Thoughts

Dyssynergic defecation is a common cause of chronic constipation. Luckily, pelvic floor therapy for constipation is an effective treatment.

If you’re struggling with constipation, it’s important to ensure other modifiable factors are well-managed in conjunction with using pelvic floor therapy as a treatment. This includes getting enough fluid and fiber through your diet. If you’re struggling to make dietary changes to manage chronic constipation, a registered dietitian can help.

Spend any amount of time on social media these days, and you'd think protein is the answer to all your health concerns. Protein coffee, protein cereal, protein deserts…even foods that never needed protein are getting a boost.

Protein absolutely plays an important role in overall health. But when it comes specifically to gut health, fiber is the real MVP.

Why Gut Health Depends on What Your Microbes Eat

Your gut is home to trillions of microorganisms collectively known as the gut microbiome. These microbes, which include bacteria, viruses, fungi, and more, influence everything from digestion and metabolism to inflammation and immune function

But microbes need fuel to survive.

Unlike human cells, your gut microbes thrive on dietary fiber—not protein—as their main source of energy. When you eat fiber, your gut microbes ferment it and produce compounds that actively support health.

However, when fiber intake is low, your gut microbes are forced to rely on other sources of fuel, including protein. And that shift can change which metabolic byproducts are produced in your gut. And spoiler alert—that's not always for the better.

What Happens When You Eat Fiber

Fiber is a type of carbohydrate that resists digestion in the small intestine. Instead of being absorbed, it travels to the colon intact. 

This is where the magic happens. Your gut microbes ferment fiber, producing a variety of different compounds. Some of the most important byproducts of fiber breakdown by your microbiome are short-chain fatty acids (SCFAs).

SCFAs are incredibly beneficial for overall health. Here are just some of their benefits:

  • Nourish colon cells
  • Strengthen the gut barrier
  • Reduce inflammation
  • Support regular bowel movements
  • Maintain a healthy gut pH
  • Protect against several diseases

In other words, fiber doesn't just help you poop—it actively supports the structure and function of your gut.

The Different Types of Fiber (And Why They All Matter)

You might be surprised to learn that not all fiber works the same way. Soluble fiber, which dissolves in water to form a gel-like substance, slows digestion, helps regulate blood sugar, lowers cholesterol, and, in some cases, acts as fuel for your good gut microbes. The fiber that can act as fuel for your gut microbes is called prebiotic fiber, and you can think of it as fertilizer for your gut microbiome. 

In contrast, insoluble fiber does not dissolve in water, but adds bulk to stool, helping promote gut regularity and speeding up the transit of waste through your digestive tract.

Both types of fiber are needed for a healthy gut, but soluble fiber is typically "gentler" on digestion and can be especially helpful for people with IBS.

What Happens When Protein Reaches the Colon

Protein is essential for muscle repair, immune function, and hormone regulation, and most of it is digested and absorbed in the small intestine. However, when large amounts of protein (especially protein from animal products) reach the colon, your gut microbes break it down through fermentation. Unlike fiber fermentation, protein fermentation produces compounds that can negatively affect gut health.

Byproducts of protein fermentation can include ammonia, hydrogen sulfide, phenols, and indoles. In large amounts, these compounds have been linked to gut barrier irritation, increased inflammation, unfavorable changes in gut microbiome composition, and a potential increase in colorectal disease risk.

This doesn't mean protein is harmful, but it highlights that a high-animal-protein, low-fiber diet shifts microbial activity toward less beneficial metabolic pathways. In other words? The extremely popular carnivore diet is not a good choice for gut health. Overall, it's best to focus on plant-based sources of protein, which studies show can improve gut microbiome composition. 

Why Fiber Matters More Than Protein for Gut Health

From a gut health perspective, fiber has several advantages over protein:

  • Feeds beneficial microbes
  • Produces anti-inflammatory compounds
  • Supports stool consistency and transit
  • Improves microbial diversity

Most people meet or exceed the recommended protein intake, but fall dramatically short on fiber intake (some studies suggest that as many of 95% of people in the United States don't reach the recommended fiber intake).

The National Academy of Medicine recommends that women aim for around 25 grams of fiber per day, while men should target about 38 grams per day.

Simple Ways to Increase Fiber Intake

Increasing your fiber intake doesn't require a complete diet overhaul. Small, consistent changes tend to work best, especially if you have a sensitive digestive system.

Instead of removing foods from your diet, focus on adding fiber where you can or switching to higher fiber options:

  • Toss canned beans or chickpeas into salads
  • Add chia or ground flax seeds to your yogurt
  • Include at least one plant food at every meal
  • Switch to whole wheat or fiber-enriched pasta
  • Choose rolled oats instead of sugary breakfast cereals
  • Cook and cool starchy foods like potatoes, rice, and pasta before eating to naturally increase resistant starch (a type of prebiotic) content

To avoid digestive problems, increase your fiber intake slowly by 2-3 grams per day, and ensure you're drinking plenty of fluids to keep things moving smoothly. To increase the diversity of fiber you're providing to your microbes, aim to eat 30 different plant foods (which include fruits, vegetables, legumes, nuts, seeds, herbs, and spices) per week.

The Bottom Line

Protein is essential for overall health, but when it comes to gut health, fiber plays the starring role. It feeds your beneficial gut microbes, strengthens the gut linking, and produces anti-inflammatory compounds that help keep your digestive system running smoothly. Meanwhile, diets high in protein but low in fiber may encourage metabolic byproducts linked with less favorable gut outcomes.

If your priority is improving gut health, the evidence consistently points in one direction. Eat more fiber, and your gut microbes will thank you.

    I have chronic constipation, low motility, Ehlers Danlos syndrome and am working with a GI at UCLA who has recommended a manometry test and biofeedback. Am interested in the biofeedback and what it involves and if it’s too late for me brain and body to relearn at age 71.

      Alicia,
      It is worth trying biofeedback therapy with a physical therapist trained in this area. I have had clients in their 80’s meet with physical therapists trained in pelvic floor therapy for constipation and have results.
