By Noah Williams Let’s be honest—pooping is something we all do, but it’s not exactly dinner table conversation. Still, if you’ve ever wondered why it feels so satisfying to go, you’re not alone. So, we went straight to the experts: gastroenterologists.
Turns out, there are real scientific reasons behind that “ahh” feeling. “Pooping involves a mix of body and brain working together—not just to get rid of waste, but to make you feel better afterward,” says Dr. David D. Clarke, a gastroenterologist and professor emeritus at Oregon Health & Science University. In short: nope, you’re not imagining it. Here’s what’s really going on.
It Triggers a Chill-Out Response
That post-poop sense of calm? You can thank your vagus nerve for that. This nerve starts in your brain and stretches all the way down to your digestive organs, acting like a control line for a bunch of body functions—including digestion and going to the bathroom.
“When you poop, the vagus nerve gets stimulated, which can slow your heart rate and lower your blood pressure a bit—leading to a relaxed, even euphoric feeling,” says Dr. Clarke. Some people even call it ‘poo-phoria.’ Yep, that’s a thing.
Your Gut Pumps Out Feel-Good Chemicals
Serotonin is one of the body’s main mood boosters—and guess what? Most of it (about 90%) is actually made in your gut, not your brain.
“It’s released by cells in the intestines and helps move poop along by triggering muscle contractions,” says Clarke. So not only does serotonin help with digestion, but it can also lift your mood after you go.
But too much or too little serotonin can mess things up. “Low serotonin can make you constipated. Too much? That might cause diarrhea,” says Dr. Adam Moskowitz, a GI expert in New York. He adds that serotonin imbalances are also tied to IBS and stomach pain.
It Feels Like a Huge Relief
Holding it in? Not fun. But finally going? Total relief—physically and mentally.
And ignoring the urge too often? That’s a one-way ticket to constipation. When your body says it’s time, try to listen and go.
That said, if pooping hurts, don’t just deal with it. “Pain during bowel movements could mean something’s up—like hemorrhoids, fissures or even inflammatory bowel issues,” says Clarke. Avoiding the bathroom out of fear can actually make symptoms worse, so talk to a doc if things don’t feel right.
How to Keep Things Moving Smoothly
Now that we know why pooping feels awesome, here’s how to make sure you stay regular and comfortable:
1. Eat More Fiber.
“Fiber helps with both constipation and loose stools—it’s kind of a gut superhero,” says Moskowitz. Most of us don’t get enough. Aim for 25–30 grams daily.
Bianchini, a registered dietitian, suggests simple add-ins: “Chia or flax seeds are super easy—toss them in yogurt or smoothies. Beans are amazing too—just a cup gives you half your daily fiber needs.”
2. Drink Plenty of Fluids.
“Water helps soften stool and move everything along,” says Bianchini. And if you’re boosting fiber, hydration is extra important.
Don’t forget that fruits, veggies, coffee, and herbal teas (like ginger) also count toward your fluid intake.
3. Stay Active.
“Movement helps digestion—and most of us don’t move enough,” says Moskowitz. Even a short daily walk can keep your gut in good shape. No need for intense workouts; just keep your body moving.
4. Eat Regular, Balanced Meals.
Your gut loves a steady routine. “Skipping meals or eating erratically can slow things down,” says dietitian Destiny Howard. Nourish your body consistently, and your bowels will thank you.
5. Slow Down When You Eat.
Shoveling food in fast can leave you feeling bloated. “Chew well, eat slowly and try to enjoy your food,” says Howard. Sitting down to eat mindfully helps your digestion work better.
6. Stick to a Routine.
Ever notice you need to poop at the same time every day? That’s your body’s internal clock doing its thing.
“Going around the same time daily helps keep your digestive rhythm steady,” says Clarke. When the urge hits, don’t wait—answer the call!
Bottom Line
If going to the bathroom makes you feel good, you’re not weird—it’s totally normal. According to gut health pros, that feel-good sensation comes from your body relaxing, your brain getting a dose of serotonin, and just plain old relief.
But if things are off—like if you’re going too rarely or only passing loose stool—it’s worth chatting with your doctor. Because honestly, pooping should feel good!
