Microplastics, involved in IBD?

Microplastics are everywhere: in water, in the air, in food… The latest analyzes show that we consume tens of thousands of particles each year. However, studies on animal models have shown that exposure to these products leads in particular to intestinal inflammation and changes in the microbiome. This is why a Chinese team sought to determine whether these microplastics could contribute to the development of ulcerative colitis and Crohn’s disease, inflammatory bowel diseases (IBD). Especially since the incidence of these diseases is growing.

1.5 more particles in IBD

To do this, they started by comparing stool samples from 50 healthy people and 52 with IBD. Their finding is in line with their initial hypothesis since the samples from sick people contained about 1.5 times more particles per gram than those from the control group. Another observation: the samples from the sick group showed smaller particles.

Through a questionnaire, the researchers found that people with the habit of drinking bottled water, eating take-out food and who were exposed to a lot of dust had the most microplastics in their stool. And this in both groups. Finally, people with the most severe IBD symptoms had the most microplastics in their samples.

Although the evidence seems to point to a strong link between microplastics and MICI, researchers still refuse to establish a cause-and-effect relationship. Indeed, people with IBD may also accumulate more particles due to their disease.
