White Coat Syndrome and the Nocebo Effect

What if the biggest enemy of your healing isn’t your illness, but the person in the white coat who tells you that you can’t get better?

Doctors have an enormous influence on their patients. There’s even such a thing as “white coat syndrome.” This refers to people who experience high blood pressure mainly when they’re at the doctor’s office, but at home, their blood pressure is normal. That’s why you might sometimes be advised to measure your blood pressure at home as well, to check whether the doctor is causing this effect or if you’re actually suffering from high blood pressure[1].

This alone shows that the white coat can have a significant impact on a person’s physiology, but that’s not all.

Last weekend, I taught Module 5 of Level 3 in our training program. Students submit videos of sessions they conduct with clients, and I provide feedback on them.

It’s super interesting, and especially amazing to see how much growth is evident time and again between Block 4 and Block 5. But this time, there was one session that made my hair stand on end.

The case involved a client with colitis. For decades now, the medical community has been saying in unison: colitis is incurable. Period. All scientific studies indicate that it is impossible to cure this condition, let alone through hypnotherapy.

While hypnosis is already more or less the standard treatment for Irritable Bowel Syndrome [2], this is not the case for colitis.

And you know what? Up to a point, I can go along with the doctor on that. If, as a doctor, you firmly believe what science has fed you, then that is your worldview.

But then comes the moment when such a patient suddenly returns to you after a few hypnotherapy sessions. No more complaints, no more prednisone, able to eat whatever he wants again, and feeling radiant and fit.

So what is a doctor’s role? You might think: “Wow, that’s fantastic! My goal is to help and heal people, and apparently I’ve succeeded, even though I don’t fully understand the exact path to get there. Let’s keep going!” But no, not at all.

This doctor was determined to change that perception.

The Power of the White Coat and the Nocebo Effect

That doctor launched into a real tirade: “That’s impossible! It can’t be done! It doesn’t exist! It’s incurable! All the studies say the same thing! ”Just imagine that. You walk in, full of pride, with the best news of your life: after decades of pain and misery, you’re cured. And your treating doctor just crushes you like that.

After that pleasant consultation, the man gets into his car and drives home. But what do you think happens at the roundabout? That authoritarian doctor’s voice continues to ring loud and clear in his head.

Nonsense, it’s impossible, you’re incurable—that’s not true!

At the second roundabout, his stomach suddenly starts rumbling again. He hadn’t had any problems for months, and then just one day later? All the symptoms are back with a vengeance. It’s even known that doctors can accidentally cause this[3].

Now that’s what I call a top doctor, isn’t it? Fire him immediately—send him packing on the spot with a coat of tar and feathers. You’re a doctor, aren’t you?

Your job is to help people get better, not to single-handedly talk someone who has just recovered back into illness simply because it doesn’t fit into your narrow-minded box.

This is a textbook example of the nocebo effect: the dark counterpart to the placebo effect. Thanks to the negative suggestions from an authority figure—in this case, a doctor in a white coat who takes your symptoms completely seriously—the brain simply brings the symptoms back to the surface.

The Amazing Placebo Effect

Medical science often dismissively exclaims, “Yeah, but that’s just a placebo!”

But wait a minute. Do you have any idea how powerful a placebo is? Serious research has been conducted on sham knee surgeries, in which the patient received only an incision but was not actually operated on. What did they find? Those placebo surgeries were just as effective as the real procedures[4]!

The human brain and our bodies are so incredibly complex and wondrous; we actually still know very little about them.

A placebo isn’t “just” something; it’s an incredibly powerful mechanism. A doctor in a white coat already has a built-in placebo effect that increases a medication’s effectiveness by about fifteen percent. If a doctor says, “This is a very strong painkiller,” then it feels like a strong painkiller, even if it’s just a sugar pill.

I’ve experienced it firsthand myself. Years ago, after a severe allergic reaction to concrete, I broke out in hives all over my body and within a day I could no longer walk. I looked just like a Michelin man. My family doctor gave me two capsules from a special cabinet and said, “Take one first, and if it works, bring the other one back because they’re from Switzerland.”

I took one, and my symptoms went away immediately! It wasn’t until much later that I realized they were just placebo pills—when I found out that my neighbor behind me and my father were given the exact same pills for completely different conditions.

Was that doctor a charlatan? Well, I was damn glad about it! I was able to move forward again. And isn’t that exactly what a doctor is supposed to do? Help people move forward, instead of pinning them down with statistics and dogmatic rules.

Time for a breath of fresh air in healthcare

Of course, I fully understand that doctors want to work based on evidence. That makes sense—that’s their training, and that’s how the system is set up.

And fortunately, there are also doctors who maintain a level-headed perspective on the matter.

When I recovered from an overactive thyroid back then—which, according to my doctor at the time, was absolutely impossible—he at least dryly remarked, “Well, you’re a laboratory anomaly.”

Okay, well, fine then—I’m that person! But at least he didn’t shoot me down right away.

The ideal doctor says: “Personally, I don’t understand a thing about it and I don’t believe in it, but if this has apparently worked for you: wow, that’s great—keep it up!”

And then they go back to business as usual. They certainly don’t have to immediately start referring patients en masse to alternative practitioners or hypnotherapists—as long as they respect the patient’s positive outcomes and don’t undermine them with their own limiting beliefs.

It’s time we really thought hard about how we communicate. Words have an impact. Suggestions have an impact. Whether you’re a doctor, a parent, a manager, or a coach: what you say makes an impression.

Let’s stop dismissing or mocking results that simply fall outside our own frameworks, and instead learn to make the most of the immense power of our own minds.

What do you think about this? Have you ever had a doctor or expert say something that immediately made you feel worse, or have you experienced a miraculous breakthrough that, according to the books, was impossible? Let me know in the comments below—I’m really curious to hear your stories!
