Constipation: Why You Can’t Poop and How Pelvic Floor Physical Therapy Can Help

We all know it. We need to poop. Every day, if possible.

If you've ever been constipated, you know how awful you can feel when you just can't have a bowel movement. You may feel bloated, uncomfortable, heavy, nauseous, or just plain off. It can be incredibly frustrating when something that should happen automatically suddenly becomes something you have to think about, plan for, and work at.

And constipation is incredibly common.

But constipation isn't always as simple as “you need more fiber” or “drink more water.” There can be many different factors contributing to constipation, and often there is more than one.

Hydration, nutrition, gut motility, hormones, your microbiome, pelvic floor function, your nervous system, medications, activity level, and underlying health conditions can all affect bowel function.

Some of these things we have a lot of control over, while others we have much less control over.

Health conditions such as Ehlers-Danlos syndrome (EDS), hypermobility spectrum disorders (HSD), POTS, MCAS, pregnancy, endometriosis, and other chronic conditions can also contribute to constipation and other forms of bowel dysfunction.

Understanding why constipation is happening can be the key to finding treatment strategies that actually work for you.

Let's look at some of the most common contributors.

Hydration

One of the first things to consider with constipation is hydration.

Your body needs adequate fluid to help keep stool softer and easier to pass. When you're dehydrated, your colon absorbs more water from the stool as it moves through your digestive tract, which can contribute to harder, drier stool.

But “drink more water” isn't necessarily the whole answer.

Your individual hydration needs vary based on your body, activity level, environment, diet, medications, and health conditions. For people with POTS or other conditions affecting fluid and electrolyte balance, hydration may need to be approached differently.

The goal isn't simply to drink as much water as possible. It's to make sure your body has the fluids and electrolytes it needs to function well.

Nutrition and Fiber

What and how much you eat can also affect bowel function.

Fiber can be incredibly helpful for constipation because it can increase stool bulk and support regular bowel movements. But more fiber isn't always better.

If you're under-fueling, eating very little fiber, or suddenly increasing your fiber intake without adequate fluid, you may actually experience more bloating and discomfort.

There are also different types of fiber, and people respond to them differently. Someone with significantly slowed gut motility may not tolerate large amounts of certain high-fiber foods.

This is why constipation treatment needs to be individualized.

The goal isn't simply to eat more fiber. It's to figure out what your digestive system can tolerate and what helps your bowel movements become more consistent.

Hormones

Hormones can have a significant effect on bowel function.

Many people notice changes in their bowel habits throughout their menstrual cycle. Pregnancy can also dramatically change gastrointestinal function, particularly as hormonal changes can slow gastrointestinal motility.

Postpartum hormonal changes can create another significant shift in bowel function.

Some people also experience changes in constipation during perimenopause, menopause, or when starting or stopping hormonal medications.

If you notice that your constipation follows a predictable hormonal pattern, that's valuable information. It can give you and your healthcare providers a clue about what may be contributing to your symptoms and when additional support may be most helpful.

Gut Motility and EDS/HSD

For people with EDS or HSD, constipation can be particularly complicated.

Some people with hypermobility disorders experience gastrointestinal symptoms such as constipation, bloating, abdominal pain, reflux, or changes in gut motility.

There may be multiple overlapping contributors, including connective tissue differences, autonomic dysfunction, medication effects, dietary restrictions, and pelvic floor dysfunction.

This means treating constipation in someone with EDS/HSD may require looking beyond the bowel itself.

If gut motility is reduced, simply adding more fiber may not solve the problem. In some people, increasing fiber too aggressively can actually make bloating and discomfort worse.

The goal is to understand what may be slowing things down and address the factors that can be modified.

Your Nervous System Matters

Your digestive system is closely connected to your nervous system.

Your body needs to be able to shift into a state that supports digestion and elimination. Chronic stress, pain, poor sleep, illness, and autonomic dysfunction can all affect the way your nervous system communicates with your digestive system.

For people living with chronic pain or complex conditions, the nervous system may spend a lot of time in a heightened state of alertness. Others may experience periods of shutdown or reduced autonomic responsiveness.

This isn't as simple as telling someone to “relax.”

Instead, we want to help your nervous system develop more flexibility so your body can appropriately support digestion and elimination.

Interoception: Can You Feel When You Need to Go?

Another often-overlooked piece of constipation is interoception, which is your ability to sense what's happening inside your body.

You may think the urge to have a bowel movement should be impossible to miss. But for some people, signals from the bowel can be muted, delayed, or difficult to recognize.

You might regularly ignore the urge because you're busy, at work, caring for your kids, or simply don't feel a strong signal until the stool has already accumulated.

Over time, repeatedly ignoring these signals can contribute to changes in your awareness of bowel fullness and urgency.

This can create a cycle:

Less sensation → fewer bowel movements → more stool accumulation → altered sensation → even less awareness of the urge to go.

Improving bowel function may therefore involve learning to recognize your body's earlier signals rather than waiting until the urge becomes overwhelming.

And sometimes improving interoception means turning down the “noise” from other body signals.

If your nervous system is constantly processing pain, muscle tension, fatigue, dizziness, or other symptoms, subtle signals like thirst or the urge to have a bowel movement can be much harder to notice.

Are You Gripping Your Way Through Life?

This is one of the pieces of constipation that is often overlooked.

Your abdominal muscles, diaphragm, and pelvic floor work together to manage pressure inside your abdomen.

When you have chronic pain, hypermobility, pelvic floor dysfunction, or a history of injury, you may develop a habit of constantly bracing or gripping through your abdomen and pelvic floor.

This can happen so automatically that you don't even realize you're doing it.

When you have a bowel movement, your body needs to generate pressure from above while allowing the pelvic floor and anal sphincter to relax and open.

If you're bearing down while simultaneously gripping your pelvic floor, you may end up working against yourself.

It's a little like trying to push something through a door while someone is holding the door closed.

Pelvic Floor Tension and Coordination

Your pelvic floor plays an important role in bowel function.

These muscles need to be able to:

• Contract when you need them to provide support and maintain continence

• Relax when you need to empty your bowel

• Coordinate with your diaphragm and abdominal muscles

• Respond appropriately to changes in pressure

• Lengthen and open enough to allow stool to pass

A pelvic floor that is weak can contribute to bowel dysfunction.

But a pelvic floor that is too tense, overactive, or poorly coordinated can also make it difficult to have a bowel movement.

This is why “strengthening your pelvic floor” isn't automatically the answer.

Sometimes the most important thing your pelvic floor needs to learn is how to let go.

A pelvic floor physical therapist can assess whether your muscles are weak, tight, poorly coordinated, or some combination of these things—and help you retrain them accordingly.

How Can Pelvic Floor Physical Therapy Help Constipation?

At Intrinsic Physical Therapy & Wellness, we look at constipation from a whole-body perspective.

As pelvic health physical therapists with experience treating EDS/HSD, POTS, MCAS, and other complex conditions, we understand that constipation often doesn't have just one cause.

Our goal is to figure out what is contributing to your bowel dysfunction and develop a treatment plan that addresses those factors.

Treatment may include:

Hydration and nutrition education

We can help you understand how hydration, nutrition, and fiber may be affecting your bowel function and identify strategies to support more consistent bowel movements.

Improving interoception

We can help you learn to recognize your body's internal signals, including abdominal fullness and the urge to have a bowel movement.

Breathing and toileting mechanics

Your breathing, diaphragm, abdominal muscles, and pelvic floor all work together during a bowel movement.

We can teach you breathing strategies, positioning, and toileting techniques that help you work with your body's natural mechanics rather than against them.

This also includes learning when it's time to stop trying. Sitting on the toilet and repeatedly straining isn't necessarily helping. Sometimes your body simply isn't ready to empty.

Pelvic floor coordination

We can help you learn when to activate your pelvic floor—and, perhaps even more importantly, when to relax it.

For someone with pelvic floor overactivity, learning to lengthen and release these muscles can make a significant difference in bowel function.

Manual therapy

Depending on your individual presentation, manual therapy may be used to address abdominal wall tension, pelvic floor muscle tension, rib cage and diaphragm mobility, and other areas that may be contributing to difficulty with bowel movements.

Some patients may also benefit from visceral mobilization techniques intended to support mobility of the abdominal organs.

Nervous system regulation

We also look at your nervous system and help you develop strategies that support regulation and flexibility.

This can be particularly important for people living with chronic pain, POTS, EDS/HSD, MCAS, or other complex conditions.

Working alongside medical management

Sometimes you need help now.

Medications or laxatives may be appropriate as a short-term strategy, particularly during pregnancy, after surgery, medication changes, or significant hormonal shifts.

Physical therapy doesn't replace medical management when medication is needed. Instead, we can work alongside your medical providers to address the physical and functional contributors to your bowel dysfunction.

When Should You See Your Doctor About Constipation?

While constipation is common, some symptoms warrant medical evaluation rather than simply trying to manage the problem at home.

Talk with your healthcare provider if you experience blood in your stool or rectal bleeding, unexplained weight loss, persistent or severe abdominal pain, repeated vomiting, fever, a significant or unexplained change in your usual bowel habits, or constipation that is persistent, worsening, or not responding to your usual strategies.

If you are unable to pass stool or gas and have significant abdominal swelling or pain, seek prompt medical attention.

Your doctor or other medical provider can help determine whether there is an underlying medical condition, medication effect, or other issue that needs to be addressed.

You Don't Have to Just Live With Constipation

Constipation isn't simply an inconvenience.

When you're not having regular bowel movements, it can affect your comfort, appetite, energy, pelvic health, abdominal pressure, and overall quality of life.

And if you've been told to “just drink more water,” “eat more fiber,” or “take a laxative” without anyone looking at the bigger picture, it can be incredibly frustrating.

Your bowel function is influenced by your entire body.

Hydration. Nutrition. Hormones. Gut motility. Your nervous system. Your breathing. Your abdominal muscles. Your pelvic floor. Your ability to sense what's happening inside your body.

All of these pieces can matter.

At Intrinsic Physical Therapy & Wellness, we help people with complex pelvic health and bowel dysfunction understand what's happening in their bodies and develop strategies that address the why, not just the symptom.

If you're struggling with constipation, incomplete bowel movements, straining, bloating, or feeling like you have to work way too hard just to poop, reach out to learn how pelvic health physical therapy may be able to help.
