Gut Biome-Mediated Barriers to Nutrient Absorption: Investigating the Impact of Dysbiosis

Abstract

The gut microbiome is essential for nutrient absorption, immune function, and overall metabolic health. A balanced microbial community allows for the breakdown of carbohydrates, proteins, fats, vitamins, and minerals into maximally absorbed nutrients and provides protection against inflammation. Dysbiosis, or microbial imbalance, disrupts these processes and leads to malabsorption, barrier dysfunction, and toxic metabolite production. These imbalances contribute to a wide variety of diseases, from obesity, diabetes, and cardiovascular disease to anemia, osteoporosis, and nervous system dysfunctions. Advances in sequencing, metabolomics, and functional assays have facilitated an enhanced understanding of the ecological and biochemical complexity of gut microbes. AI-based models are also providing new insights into personalized diet and therapeutic approaches. Through the redefinition of malnutrition and chronic disease within microbial ecology, science proves the potential for engineered probiotics, precision prebiotics, and gut-targeted therapies. These innovations hold the potential to improve global health and propel precision medicine in nutrition.
