Environmental and Lifestyle Factors in Inflammatory Bowel Diseases
AI summary Read the abstract
This review pulls together existing research on how everyday habits—diet, exercise, sleep, stress, and smoking—affect inflammatory bowel disease (IBD), a chronic condition causing gut inflammation. It found that eating more whole foods and Mediterranean-style meals (instead of heavily processed Western diets), staying active, and managing stress may help control symptoms, while emerging evidence suggests environmental pollutants like microplastics, pesticides, and heavy metals could also play a role in triggering or worsening the disease. The takeaway: for people with IBD, lifestyle choices matter alongside medication, though
Inflammatory bowel disease (IBD) is a chronic, multifactorial disease resulting from complex interactions between the immune system, gut microbiota, genetic susceptibility, and environmental factors. Although advances in pharmacologic therapies have improved disease control, increasing evidence indicates that lifestyle and environmental factors influence disease course and patient well-being. In this review, we assess the impact of lifestyle factors (diet, physical activity, sleep, mental health, and smoking) and environmental factors (pesticides, microplastics, and heavy metals) on IBD. Our manuscript highlights the importance of minimizing highly processed foods, such as those in the Western diet, while promoting a whole-food and Mediterranean diets, regular physical activity, and monitoring for micronutrient deficiencies. We also provide information on sleep disturbances, mental health, and disease activity, as well as interventions such as cognitive-behavioral therapy and mindfulness, which may improve the quality of life of these patients. Emerging evidence suggests that environmental pollutants, including microplastics and pesticides, may affect IBD risk and progression, highlighting the need for further research. Integrating structured lifestyle recommendations into clinical care may have a significant role in improving outcomes in patients with IBD.

Environmental pollutants and the rising burden of inflammatory bowel disease in East Asia: a narrative review
AI summary Read the abstract
This review pulls together existing research on why inflammatory bowel disease (IBD) is rising sharply in East Asia, pointing to air pollution, heavy metals in water and food, pesticides, and microplastics as likely contributors. Scientists think these pollutants may harm health by disrupting gut bacteria and weakening the intestinal lining, which can trigger chronic inflammation. This matters because it suggests that cleaning up our environment—not just changing diets or genetics—could be a real tool for preventing this painful, lifelong digestive disease.
The exposome and inflammatory bowel disease: a framework for primary and primordial prevention
AI summary Read the abstract
This review paper argues that everyday environmental exposures, like food chemicals, pollution, and even microplastics, may play a bigger role in triggering inflammatory bowel disease (IBD) than previously thought. The authors propose a prevention strategy: identifying at-risk individuals early, while also reducing harmful exposures for everyone to lower IBD risk community-wide.
Adverse health effects of emerging contaminants on inflammatory bowel disease
AI summary Read the abstract
This review summarizes how emerging environmental contaminants, including microplastics, endocrine disruptors, herbicides, and heavy metals, may contribute to inflammatory bowel disease. Researchers found evidence that these pollutants can disrupt gut barrier function, alter the microbiome, and trigger immune responses linked to bowel inflammation. The study suggests that reducing exposure to these increasingly common contaminants could help lower the rising incidence of inflammatory bowel disease.
Analysis of Microplastics in Human Feces Reveals a Correlation between Fecal Microplastics and Inflammatory Bowel Disease Status
AI summary Read the abstract
Researchers analyzed microplastics in the stool of patients with inflammatory bowel disease (IBD) and healthy volunteers, finding that IBD patients had significantly higher concentrations of microplastics in their feces. PET plastic and polyamide were the most common types found, likely originating from food packaging and dust. The positive correlation between microplastic levels and IBD severity suggests that microplastic exposure may be linked to gut inflammation, though it is not yet clear whether the plastics contribute to the disease or the disease causes more plastic retention.
Microplastics and Inflammatory Bowel Disease: From Environmental Exposure to Clinical Uncertainty
AI summary Read the abstract
This review paper summarizes existing lab and human research on tiny plastic particles and inflammatory bowel disease (IBD). Lab studies suggest these particles may disrupt the gut's protective lining and worsen inflammation, while human studies found associations between plastic levels and IBD symptoms, but do not prove plastics cause the disease.
