Microplastics have been discovered in the large neck arteries that supply blood to the brain, with stroke survivors showing the highest levels of accumulation, according to a recent small study.
Plaque buildup in the necks of stroke survivors may be loaded with microplastics

Key Takeaways:
- Microplastics are infiltrating major neck arteries.
- Stroke survivors have the highest amounts of microplastics in arterial plaque.
- Findings are based on a small study.
- Presence of microplastics could have health implications.
- Fatty buildup in arteries is a key site for microplastic accumulation.
Tiny Plastics in Vital Blood Vessels
Researchers have discovered that tiny pieces of plastic, known as microplastics, are infiltrating the large arteries in the neck that carry blood from the heart to the head.
Microplastics Explained
Microplastics are small plastic particles less than five millimeters in size. They result from the breakdown of larger plastic debris and can enter the human body through various means, including food, water, and air.
Study Highlights Elevated Levels in Stroke Survivors
A small study suggests that the highest amounts of these microplastics are found in the fatty buildup, or plaque, within the arteries of stroke survivors. This plaque accumulation is concerning as it can lead to arterial blockages, affecting blood flow to the brain.
Potential Health Implications
The presence of microplastics in arterial plaque might have significant health implications. While the exact effects are not yet fully understood, the findings raise questions about the role of microplastics in vascular health, especially in individuals who have experienced a stroke.
Call for Further Research
Given that the study is small, researchers emphasize the need for further investigation to determine the extent of microplastic infiltration and its impact on arterial health. Understanding this could be crucial for developing strategies to mitigate potential risks associated with microplastic exposure.
