Gut Health Linked to Social Anxiety Disorder
20 Feb
Summary
- Social anxiety disorder affects approximately 12% of people globally.
- New research suggests a link between gut bacteria and social anxiety.
- Mice transplanted with gut bacteria from anxious people showed social fear.

Social anxiety disorder, a condition characterized by an overwhelming fear of social situations, affects around 12 percent of the population globally, making it the most common form of anxiety. It typically begins in teenage years and can significantly disrupt daily life.
Emerging research indicates that social anxiety may have biological underpinnings beyond psychological factors, potentially involving gut health and brain changes. This contrasts with introversion, which is a preference for calmer environments rather than a fear of social interaction.
Studies have shown distinct gut microbiome profiles in individuals with various mental health conditions. In a recent investigation, researchers analyzed fecal samples from individuals with and without social anxiety, observing significant differences in their gut bacteria.
To test the impact of these gut bacteria, researchers transplanted fecal matter from human participants into laboratory mice. The mice that received transplants from individuals with social anxiety displayed heightened susceptibility to social fear, specifically in social contexts, and were slower to recover from negative social experiences.
