You can catch the ‘nocebo’ effect from family, friends – even social media.

What’s Behind the Nocebo Effect?

In 1998, a mysterious phenomenon occurred in a Tennessee high school. Students and staff reported symptoms of chemical poisoning, with 38 people severe enough to require hospitalization. Investigators found no evidence of a gas leak, yet the symptoms persisted. This phenomenon is an example of the nocebo effect, where people’s negative expectations of a situation can cause them to experience symptoms.

What is the Nocebo Effect?

The nocebo effect is the opposite of the placebo effect, where a person’s positive expectations of a treatment can improve their health. The nocebo effect occurs when someone expects a negative outcome from a harmless situation, leading to the experience of symptoms.

How is this Relevant Today?

When a doctor prescribes a new medicine, they must warn patients about potential side effects. However, this warning can trigger the nocebo effect, leading to more side effects. A study found that nearly 73% of people in drug trials reported side effects even when given a placebo and told about possible side effects.

How Do Nocebo Effects Develop?

Previous experiences with treatments can shape our expectations and influence our health. Research has shown that the nocebo effect can also be transmitted socially, where observing someone experience pain from a treatment can lead to the observer experiencing more pain.

The Effects Can be Serious

For individuals, the nocebo effect can lead to unnecessary suffering and pain. Unpleasant side effects can also contribute to people abandoning their treatment. At a broader public health level, the nocebo effect can make it challenging to evaluate the safety of new technologies and public health interventions.

What Can We Do About It?

Individuals can reduce their likelihood of experiencing nocebo-driven symptoms by seeking reliable information from credible medical sources. Healthcare professionals can help by framing discussions of potential side effects in a positive way and emphasizing that most patients experience no problems.

Conclusion

The nocebo effect is a complex phenomenon that can have serious consequences for individuals and public health. By understanding how it works and taking steps to mitigate its effects, we can promote better health outcomes and reduce unnecessary suffering.
