If you’ve been diagnosed with IBS or you’re still trying to figure out what’s going on with your gut, you’ve probably heard a lot of conflicting advice.

Today, I want to break down the most common myths about IBS—misconceptions that could be keeping you stuck, frustrated, and still struggling with symptoms.

✅ Myth #1: “IBS is all in your head.”

This is one of the most damaging myths out there. And I cannot tell you how many times I’ve had patients tell me that they’ve been told this.

IBS is not just psychological. It’s a real, physical disorder involving all kinds of issues related to foods, your immune system, the microbiome in your digestive tract, the gut brain connection, and a whole lot of other things.

But it’s not a mental illness.

If someone tells you to “just relax” or that it’s “all in your head,” they don’t understand IBS. And you deserve better treatment than that.

✅ Myth #2: “IBS always involves diarrhea or pain.”

IBS can include diarrhea or abdominal pain or cramping. But those symptoms are not required for you to have IBS.

IBS can be just constipation.

Or it can be just gas or bloating.

And some people with IBS have alternating diarrhea and constipation, with gas and bloating.

And some people with IBS have only abdominal pain, with no digestive symptoms.

IBS is a very broad term, that covers a lot of ground.

✅ Myth #3: “IBS and IBD are basically the same thing.”

Nope! IBS and IBD might sound similar, but they are completely different conditions.

• IBS (Irritable Bowel Syndrome) largely means that you gut isn’t working right, but there’s no gross damage to the digestive tract, other than sometimes some relative mild inflammation.  

• IBD (Inflammatory Bowel Disease), includes Crohn’s disease and ulcerative colitis, and it involves significant visual damage to the gut lining and shows up on scopes or imaging.

So while the symptoms can overlap, the treatments and long-term concerns may be very different.

✅ Myth #4: “There is a test for IBS.”

There is no test for IBS.

There are tests for lots of other things, like IBD. But there is no test for IBS.

That’s why IBS is a diagnosis of exclusion. The doctor is testing for other things and ruling them out.

Then when they don’t find anything else, the label you with IBS.

Which is still not very useful. Because it doesn’t give you any more insight into what is causing your symptoms.

The next step is to work with a doctor who can help you figure out exactly what is causing your IBS.  

✅ Myth #5: “Stress causes IBS.”

Let’s clarify: Stress can make IBS worse, and managing stress is a helpful part of treatment.

But stress is not the root cause of IBS.

Still not convinced?  Let me ask you a question. What medical condition is not made worse by stress?  

I can’t think of one either, because there isn’t one.

So stress can make your IBS worse, but it’s most likely not the real cause of your IBS. It’s exacerbating something else that is already going on down there and making it worse.

So unless your digestion is completely awesome all the time when you don’t have any stress, stress it’s rarely the full story.

In fact, your IBS is probably one of main causes of stress in your life. Not the other way around.

✅ Myth #6: “You just have to live with it.”

Absolutely not. That is outdated thinking.

Too many people are told, “There’s nothing you can do,” “There is no cure” or “Just manage your stress and eat more fiber.”

But at the IBS Treatment Center we know that IBS is very treatable, especially when you take a root-cause approach. There are real solutions. The challenge is in sorting through all of them.

Don’t settle for suffering. The right help can make a huge difference.

✅ Myth #7: “Fiber always helps.”

This one’s tricky.

Fiber helps some people with IBS—especially soluble fiber. But for others, fiber can make things worse.

It’s not one-size-fits-all.

Fiber isn’t bad—but the type, amount, and timing all matter.

And even when or if fiber helps, it’s generally not addressing the root cause of the problem.

✅ Myth #8: “IBS is caused by eating the wrong foods.”

This oversimplifies things.

Yes, diet is a huge factor in managing IBS—but the cause is often deeper than food choices.

Some people eat a great diet and still have symptoms because of gut infections, microbiome imbalances, or immune responses to seemingly harmless foods.

It’s not just about “eating clean” or cutting out gluten. It’s about the entire environment and ecosystem in your digestive tract.

✅ Myth #9: “IBS only affects your digestion.”

This might surprise you—IBS isn’t just a digestive condition.

It’s very common for people with IBS to also experience:

• Fatigue

• Brain fog

• Anxiety or mood swings

• Skin issues

• Nutrient deficiencies

Why? Because the gut is connected to the whole body, especially the brain and immune system. When your gut is out of balance, it can affect everything from how you think to how you sleep.

So if you're dealing with symptoms beyond your stomach, you're not imagining it—it’s all connected.

🎯 Final Thoughts

There’s so much misinformation about IBS out there, and unfortunately, it keeps a lot of people from getting the help they need.

If you’ve been told to just deal with it, or if you’re overwhelmed by diet advice and still feeling lost—you’re not alone, and you don’t have to suffer.

The good news is, once you understand what’s really driving your symptoms, you can finally take back control of your gut—and your life.
