# The PTSD-Bone Axis: Evidence, Mechanisms, and Management

## TL;DR

This paper reviews how PTSD affects bone health through stress-related biological pathways and suggests ways to manage the resulting skeletal issues.

## Contribution

The paper provides a comprehensive review of the PTSD-bone connection, highlighting novel therapeutic approaches like exosomal profiling and microbiome modulation.

## Key findings

- PTSD is linked to reduced bone mineral density and increased fracture risk.
- Stress disrupts bone remodeling via HPA axis, SNS activation, and inflammation.
- Personalized interventions and trauma-informed care may improve both mental and bone health.

## Abstract

This review explores the relationship between post-traumatic stress disorder (PTSD) and bone health, focusing on how chronic psychological stress influences skeletal integrity through neuroendocrine, immune, and behavioral pathways.

Clinical and preclinical studies demonstrate PTSD is associated with reduced bone mineral density, impaired healing, and fracture risk. Mechanistic insights implicate hypothalamic-pituitary-adrenal (HPA) axis dysregulation, sympathetic nervous system (SNS) overactivation, and chronic inflammation in disrupting bone remodeling. Additional risk modifiers include sex-specific biology, early-life adversity, and glucocorticoid sensitivity. However, selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), anti-inflammatory agents, and emerging tools like exosomal profiling and microbiome modulation show promise in mitigating stress-related bone loss.

PTSD contributes to skeletal fragility through complex, multisystem mechanisms. Trauma-informed care integrating bone health screening and personalized interventions may improve psychological and musculoskeletal outcomes. Future research should prioritize longitudinal, mechanistic studies to guide holistic management of trauma-related disease.
