Belief And Expectation Alone Can Create Symptoms


Hi Reader ,

Belief and expectation alone can create symptoms.

Take the fake knife prank on social media demonstrating the powerful connection between the mind and body, where a strong mental expectation of a real knife triggers intense fear, shock, and alarm.

Then there's the great example of the lemon imagery that will leave you puckering. Tap the button below to listen.

You can learn more about the lemon drop effect here.

And more recently, a February 2026 Lancet study reviewed 19 randomized controlled trials involving 124,000 people over an average of 4.5 years assessing undesirable effects of statin medication.

The finding was striking: 62 of the 66 listed statin side effects were not caused by the drug. Symptoms like fatigue, memory issues, sleep disturbance, and low mood occurred at the same rate in people taking a placebo. That's the nocebo effect: when the expectation of harm produces real symptoms.

Symptoms are real. The shock and alarm in the partners after they got pretend-stabbed are real.

But it is worth asking where symptoms originate. Belief, expectation and anticipation, all of which start in the mind, powerfully shape our physiology.

How we think and speak about our health and our body, and what we expect from a treatment, matter more than we realize.

The next time you worry about “catching” a cold, believe you will never get better, or doubt something will work, remember that you may be setting your body up to showcase the very thing you don't want.

I leave you with one of my most favourite Ted Talks: Dr. Lissa Rankin, MD, asking the question: Is There Scientific Proof We Can Heal Ourselves?

Mind your health (because what you believe and expect matter),

Hi! I'm Dr. Dominika Zarzeczny, ND

First inspired by the work of Dr. Gabor Mate, Dr. Dominika has focused much of her career on helping her patients connect the dots between early adversity and trauma and their impact on lifelong health and well-being. She knows that the reversal of chronic illness involves the nervous system, and so she has dedicated her practice to helping patients master their own nervous system to positively influence their mind and body, behaviours and ultimately health outcomes. Her explanation of disease doesn't pathologize or blame, but is nuanced, humanized and filled with hope. She trained with various psychologists and experts in the field of psychological trauma. She incorporates the principles of neuroscience, attachment theory, mindfulness, Polyvagal Theory and compassionate inquiry in her approach with patients. Combining these with her naturopathic training, she likes to say that she works at the intersection of science and human experience.
