What if the cause of your health problem wasn’t actually the cause at all? What if the explanation you were given sounded logical, convincing, and scientific—but was actually just an assumption? Because this happens in medicine all the time.
A doctor sees two things occurring together and assumes one caused the other. Most patients never question it. Why would they?
If your doctor tells you stress caused your IBS, cholesterol caused heart disease, or too much stomach acid caused heartburn and reflux, most people accept that as fact. But there’s a huge problem.
⚠️ Association is not the same as causation.
Just because two things are found together does not mean one caused the other. That distinction matters a lot. Because if you’re treating the wrong cause—or something that isn’t actually the cause at all—you can waste years chasing the wrong answer.
I’m Dr. Stephen Wangen. I’ve been treating IBS and complex digestive conditions for over 25 years and founded the IBS Treatment Center in 2005, where we’ve helped more than 10,000 patients recover.
One of the biggest reasons people stay sick is because they’ve been given explanations that sound convincing but were never actually proven to be the true cause.
Association simply means two things are seen together. That’s it.
If people with condition A often also have finding B, they’re associated. But that does not tell us whether A caused B, whether B caused A, whether something else caused both, or whether they simply happen to occur together.
And that remains true even if they are found together a lot.
Causation means one thing is actually driving the other. That’s a much higher standard. Yet medicine often acts like association is enough.
Take cholesterol. Most people believe high cholesterol causes heart disease.
But here’s what many people don’t realize. If high cholesterol were truly the cause, then everyone with high cholesterol would develop heart disease. But they don’t.
Lots of people have high cholesterol and never develop any measurable signs of heart disease. And when I say lots, I mean about half of people with high cholesterol. At the same time, plenty of people with heart disease don’t have dramatically elevated cholesterol.
So what does that tell us?
It tells us cholesterol can be associated with heart disease. But association alone does not prove cause.
Something else is going on underneath:
• 🧬 Inflammation
• 🩸 Insulin resistance
• ⚡ Oxidative damage
• ❤️ Vascular injury
• 🔄 Or multiple factors together
Finding something present doesn’t automatically mean it created the problem.
Firefighters are always associated with fires. That doesn’t mean firefighters caused the fire.

I can’t tell you how many patients have told me:
“My doctor said my IBS is caused by stress.”
Really? Stress?
That’s a classic association-versus-causation mistake.
Because yes, stress can absolutely affect the digestive system. Stress can worsen symptoms, trigger flares, and make existing digestive issues feel much more intense. And lots of people have stress. In fact, stress never makes things better.
But does that mean stress caused your IBS?
Probably not. And certainly not in my world.
If you already have an underlying digestive issue, stress will simply make it more obvious. That’s association. It’s not the same thing as being the root cause.
Then people are told:
“Your gut is just sensitive.”
Again, is that the cause? Or is that the result of something else?
If your digestive system is reacting to foods, inflammation, infections, motility problems, bacterial imbalance, fungal overgrowth, immune reactions, or something else, then of course your gut may become sensitive.
Sensitivity is real. But sensitivity itself was probably not the original cause.
That distinction matters enormously. Because treating “stress” or “sensitivity” is very different from identifying why your digestive system became reactive in the first place.
The same issue applies to acid reflux.
People assume stomach acid is the cause. But acid belongs in the stomach. That’s normal.
So if acid is going somewhere it shouldn’t, the better question is:
👉 Why?
Acid is involved. But being involved does not make it the cause.
And taking acid blockers is not addressing the real issue.
We treat this too, by the way.
So why does this confusion between cause and association happen so often?
Because finding an association is easy. If two things frequently show up together, it’s easy to assume one caused the other.
But proving actual causation is much harder.
And the truth is, many times your doctor doesn’t actually know what caused your problem. Very few doctors are comfortable saying, “I don’t know.”
So instead, you’re often given an explanation that sounds logical:
• 🧠 Stress
• ⚠️ Sensitive gut
• 🔥 Too much acid
Maybe those things are involved. But most likely they aren’t the cause.
However, once an explanation sounds reasonable enough, it gets repeated over and over until everyone starts treating it like proven fact.
And that happens in medicine all the time.
Instead of asking:
“What label did I get for my symptoms?”
Ask:
“Does this really make sense?”
And:
“What actually caused this?”
Don’t stop asking questions.
I encourage you not to settle for anything less than the real answer.
If you’ve been told your digestive symptoms are caused by stress, sensitivity, or some explanation that never fully made sense—and you’re still not getting better—there is a better explanation.
At the IBS Treatment Center, we help people find out what’s actually driving digestive problems, rather than stopping at associations or labels. And we guarantee results.
We’d love to help you too. Regardless of where you live, you can work with us via telemedicine, so give us a call at 206-317-5662.
And remember to take good care of your body—it’s the only place that you have to live. 💙
