When You've Done Everything Right and Still Can't Go
What I look for when chronic constipation won't budge
Let's talk about pooping. Or in this case, not pooping.
If you're here, I'm guessing you've already done the homework. You've eaten the prunes, bought the fancy fiber and supplements, you and your stool softener are like glue. And the bathroom has perhaps started to feel like an emotional purgatory.
Constipation is one of the most common things I see in my practice. It's also one of the most brushed off yet insidious symptoms. People get handed a laxative and a pat on the back, and years later they're stuck. Literally.
So let me tell you about someone who did everything right.
a recent case
A woman came to me in May after seeing several GI doctors. She'd had the workups. The scopes. The "everything looks fine" chats.
Her gut felt slow to the point of stopped. It churned and gurgled all day, she was gassy, and she was bloated by dinner no matter what she ate.
She'd cycled through the usual lineup: Restoralax (MiraLAX for my US friends), stool softeners, senna. The only thing that made a dent was magnesium citrate, and even that was a small dent.
She was drinking her water. Eating her veggies. Moving her body. She had the foundations down better than most people I meet, and she was out of ideas.
So we ran a SIBO breath test.
AND Methane came back high.
First, what actually counts as constipation?
A lot of people don't realize they're constipated because they still go. Technically.
Clinically, we look for things like:
Going fewer than three times a week.
Hard, pebbly stools (a 1 or 2 on the Bristol Stool Chart).
Straining, or feeling like you're pushing a boulder uphill.
That "I'm not done" feeling after you go.
Needing to press on your belly or shift positions to get things out.
You can go every day and still be constipated if it's a struggle every time. Ideally, a bowel movement is easy, complete, and takes a couple of minutes. No phone required.
Going every three days is common. Common is a low bar.
Why am I constipated if I eat healthy?
This is the question I hear most. And it makes sense. You'd think a gut full of kale would be a gut on the move.
But stool movement depends on a lot more than what's on your plate. Your gut needs muscle contractions to push things through, the right amount of water in the colon, a nervous system that feels safe enough to "rest and digest," and a microbial community that isn't pumping the brakes.
When one of those is off, fiber alone won't fix it. Piling on more fiber when you're constipated can just create a traffic jam.
Methane is a foot on the brake
Some of us have gut microbes that make methane gas. The main one is Methanobrevibacter smithii, which fun fact, isn't even technically a bacteria. It's an archaea, a whole separate branch of life that decided to move into your intestines and slow everything down.
When methane builds up, your gut contractions slow. In animal studies, methane infused into the small intestine stretched transit time by about 69%. In people, the more methane on a breath test, the worse the constipation and bloating tend to be.
This is now called IMO, intestinal methanogen overgrowth. You'll still hear people call it methane SIBO. Same idea, just with a fancy new name.
Once you know methane is in the picture, a lot of things make sense. Laxatives can push forward BUT they can't take the foot off the brake.
How methane SIBO is tested
The main tool is a breath test. You drink a sugar solution (usually lactulose or glucose), then blow into tubes at set times over a couple of hours. The microbes in your gut ferment that sugar and produce gases, which travel into your bloodstream and out through your breath.
For methane, a level of 10 ppm or higher at any point is generally considered positive.
It's a simple test you can do at home. The tricky part is reading it well. Prep matters, the timing of the gas rise matters, and the result always needs to be matched to your symptoms. A number on a page means more when someone knows your whole picture.
Clues it might be more than a fiber problem
In my practice, these are the very specific patterns that make me want to test:
Constipation that barely responds to laxatives, or only responds to the strong stuff.
Bloating that builds as the day goes on, even if you wake up flat.
Fiber and prebiotics making you more bloated.
Symptoms that started or got worse after food poisoning or a stomach bug.
Feeling a little better on a course of antibiotics, then right back where you started.
If you're thinking, oh wait this is me, a breath test is worth a conversation with a provider who knows how to read one!
For my client, it was the missing piece. We treated the methane, supported her motility afterward so it wouldn't creep back, and she now goes every single day.
Every day. After years! That's the kind of message I love getting.
Other things that might be slowing your gut down
Methane is one piece of the puzzle. When constipation sticks around, I also look at:
Your thyroid. Thyroid hormone sets the pace for your metabolism, and your gut follows along. A sluggish thyroid often means a sluggish gut, even when labs are on the edge of the range.
Your cycle. Progesterone relaxes smooth muscle, including the muscle in your gut. That's why so many women get constipated in the week or so before their period. If your constipation follows a monthly rhythm, your hormones are talking.
Estrogen clearance. Your body sends used-up estrogen out through your stool. When stool sits around too long, some of that estrogen can get reabsorbed. Constipation and heavy, painful, or PMS-heavy cycles love to show up together.
Stress. Your gut has its own nervous system, and it takes cues from your brain. When you're living in go-mode, digestion gets moved to the bottom of the to-do list.
Your pelvic floor. Sometimes stool gets to the exit and the muscles don't coordinate to let it out. If you strain a lot, feel blocked at the end, or need to change positions to go, a pelvic floor physical therapist can be a total game-saver.
Medications and supplements. Iron, opioids, some antidepressants, antacids, and even long-term stimulant laxatives can all slow things down.
And now…the plot twist
I've also had the opposite case. Lots of them, honestly.
A client who's doing almost everything right. Clean diet, supplements, the whole kit and caboodle. And the thing that changed her life was simply drinking a little more water and walking for 10 minutes after meals.
That's it.
It sounds too simple, which is exactly why so many people skip over it.
Small habits that make a big difference
When the basics are almost there, these are the tweaks that tend to move the needle:
Water, especially if you've upped your fiber. Fiber without water is like adding more cars to a traffic jam. Things get bulkier and go nowhere faster. Here in Arizona, you likely need more than you think.
A short walk after meals. Your gut likes a walk after dinner as much as your dog does. Gentle movement helps stimulate the contractions that push things along.
Increasing fiber slowly. Going from 10 grams to 35 overnight is a recipe for a very gassy week. Add a little at a time and let your microbes catch up.
Giving yourself time in the morning. Your colon has a natural wake-up window, usually after breakfast or coffee. If you're rushing out the door, you're skipping the appointment.
Answering the urge. Holding it teaches your body to stop sending the memo.
Feet up. A little stool under your feet straightens things out anatomically. Squatting is how we were built to go.
Space between meals. Your small intestine does a cleaning sweep between meals called the migrating motor complex. Constant grazing keeps interrupting the cleanup crew. Aim for about 3 to 4 hours between meals when you can.
Slowing down to eat. Sitting down, chewing well, and taking a few breaths before a meal tells your nervous system it's safe to digest. Your gut can't do its best work while you're answering emails.
When to see a doctor right away
Constipation is usually more annoying than dangerous. But some symptoms need a medical workup before anything else:
Blood in your stool or black, tarry stools.
Unexplained weight loss.
New constipation after age 45, or a family history of colon cancer.
Severe belly pain, vomiting, or not passing gas at all.
Low iron or anemia with no clear reason.
If any of these sound familiar, please get checked out first. Then we can talk about the rest.
Frequently asked questions
Is it normal to poop every few days?
It's common, and some people are fine with it. But if you're bloated, uncomfortable, or straining, your body is asking for more support. Most people feel their best going once or twice a day.
Can SIBO cause constipation?
Yes. Methane-dominant SIBO, now called IMO, is strongly linked to constipation because methane slows gut motility. Hydrogen and hydrogen sulfide types more often lean toward diarrhea or a mix of both.
Why don't laxatives work for me?
Laxatives work by pulling water into the bowel or stimulating the gut muscles. If something is actively slowing your gut down, like methane, thyroid issues, or a pelvic floor problem, laxatives are working against the current.
Is magnesium good for constipation?
Magnesium citrate and magnesium oxide pull water into the bowel and can be really helpful for some people. It's a great support tool. If you need a lot of it just to go, that's a sign to look deeper.
Can hormones cause constipation?
Absolutely. Progesterone, thyroid hormone, and stress hormones all affect how quickly your gut moves. Many women notice constipation right before their period, in pregnancy, or during perimenopause.
Can a naturopathic doctor help with chronic constipation?
Yes. My approach is to look at the whole picture, including your gut microbes, hormones, nervous system, and daily habits, and use functional testing when it makes sense. Some people need a breath test. Some need a water bottle. Most need a plan that fits their life.
So which one are you?
Maybe you're the case that needs a breath test. Maybe you're one walk away from a daily BM. Most people are somewhere in the middle, and part of my job is figuring out which small thing matters most for you.
You deserve to feel light after a meal. You deserve to not plan your day around your bowels. And you deserve a provider who keeps asking questions after the first round of "everything looks fine."
If you've done everything right and you're still stuck, let's look closer together.
With love (and a water bottle in hand),
Dr. Jess
