Microplastics could enter bone marrow and cause fractures, experts caution

Researchers in Brazil warn that tiny plastic particles may interfere with bone-cell health and raise risks of fractures and bone disease.

Microplastics are everywhere—from toothpaste and clothing to bottled water and food packaging.

New analysis from Brazil highlights a worrying twist in the microplastics story: these particles, smaller than a grain of rice, may not just affect lungs or digestion, but also sneak into our skeletons.

According to the study, microplastics have the capacity to reach bone marrow and impair osteoclasts, the cells responsible for breaking down old bone tissue. This disruption could slow down bone renewal, making skeletons weaker and more vulnerable to fractures.

Why it matters beyond the pollution debate

For years, the health focus around microplastics has been on ingestion, lung exposure or hormonal disruption. Now the research puts bones in the line of fire too—especially worrying in an ageing world where osteoporosis, diabetes and inactivity already threaten bone strength. If microplastics are an environmental factor affecting bone metabolism, it opens a new front in public-health concern.
