Disruption of this axis, through dysbiosis, altered intestinal barrier integrity, microbial translocation, and maladaptive immune activation, has become a central mechanism in the onset and progression of chronic liver diseases. Common pathways include changes in microbial composition and altered production of metabolites such as short-chain fatty acids, bile acids, ethanol, and trimethylamine N-oxide and activation of proinflammatory cascades via Toll-like receptors, NOD receptors, and inflammasomes. These alterations lead to steatosis, oxidative stress, fibrogenesis, and carcinogenesis. Notably, each liver disease presents distinct alterations. Beyond pathogenesis, modulation of the liver-gut axis has been shown to have therapeutic potential. Microbiota-targeted interventions, bile acid signaling modulators, and dietary and lifestyle strategies can restore microbial balance, strengthen the intestinal barrier, and attenuate liver injury. However, long-term safety, disease-specific efficacy, and integration with standard treatments remain key challenges. This review aims to provide an overview of the liver-gut axis.

These phenomena can impact the quality of life both independently and together. The United Nations Environmental Program has labeled these changes as a “nature crisis” because they affect various aspects of human life. In this context, health issues can be categorized as direct or indirect effects of the nature crisis. Direct effects: i. Temperature change: Heat waves are rapidly increasing mortality rates. ii. Hydrometeorological hazards: Floods can compromise water quality, creating health risks. iii. Air pollution: Climate change can increase the mobility of pollutants, worsening air quality. Indirect effects: i. Vector-borne diseases: For example, changes in weather patterns can alter the distribution of vectors, such as mosquitoes, affecting disease transmission. ii. Water-borne diseases: Increased incidence of diarrheal diseases can occur as water quality deteriorates. iii. Food-borne diseases: For instance, climate change can increase pathogens in agricultural products, posing health risks. Health impacts vary by regions, and vulnerable populations often have lower adaptive capacities. Health policies must be tailored globally and locally to address these issues, emphasizing protection for the most at-risk groups. Collaboration between the health and environmental sectors is essential to solve these growing problems. However, current adaptation policies are constantly challenged by the nature crisis.
