Chronic Illness and Conspiracy Theories: How They Connect

Explore the relationship between chronic illness and conspiracy theories — how they interact, overlap, and reinforce each other.

A chronic illness is a condition that endures for at least a year and requires ongoing medical care or consistently limits the scope of a person's daily activities. Major chronic conditions include cancer, heart disease, diabetes, lung disease, asthma, HIV/AIDS, stroke, arthritis, multiple sclerosis, epilepsy, Crohn's disease, chronic fatigue syndrome, fibromyalgia , and kidney disease, among othe

Conspiracy theories abound throughout history, especially in times of crisis, such as the worldwide Covid-19 pandemic. People who believe these theories often have a sense of existential threat: a perceived danger to one’s own life or well-being. People then consume, believe, and share these theories as a way of making sense of that threat.

The Link Between Chronic Illness and Conspiracy Theories

Chronic Illness and Conspiracy Theories are deeply interconnected psychological phenomena. Research shows that these two conditions frequently co-occur, with each often triggering or amplifying the other.

When someone experiences chronic illness, it can create conditions that make conspiracy theories more likely. Conversely, managing one can significantly improve outcomes for the other.

How Chronic Illness Affects Conspiracy Theories

The presence of chronic illness can impact conspiracy theories in several important ways:

  • Heightened nervous system activation from chronic illness can intensify conspiracy theories symptoms
  • Both share common underlying mechanisms in the brain's stress response systems
  • Addressing chronic illness often leads to measurable improvements in conspiracy theories
  • The combination can create self-reinforcing cycles that require integrated treatment

Practical Strategies When Dealing with Both

When chronic illness and conspiracy theories occur together, a combined approach is most effective:

  1. Seek professional assessment — get an accurate picture of how each affects you
  2. Address underlying causes — identify shared root causes (sleep, stress, trauma)
  3. Use evidence-based interventions — CBT, mindfulness, and behavioral approaches work for both
  4. Build support networks — social connection buffers both conditions
  5. Track patterns — use journaling to see how they interact in your life
