Abstract

The human gastrointestinal tract (GIT) contains a dynamic and diverse collection of bacteria, archaea, and fungi termed the "gut microbiome." The gut microbiome has a major impact on the host during homeostasis and disease. The connection between both the host and the microbiome is complex, although its manipulation may assist prevent or treating a multitude of morbidities. These microorganisms play a critical role in the host's energy metabolism and homeostasis. According to new research, the microbes in the gastrointestinal tract play a substantial role in host health, and alterations in its composition and function might lead to the emergence of metabolic disorders like non-alcoholic fatty liver disease (NAFLD). The resilience of the GIT microbial ecology and its tolerance to perturbation are robust but not ideal. Several factors may disrupt the GIT microbiome's homeostasis leading to dysbiosis, characterized by an imbalanced equilibrium and perturbations in gut homeostasis. Irritable bowel disease (IBD), malnutrition, and metabolic disorders, such as NAFLD, have been associated with the dysbiotic gut microbiome. Recent evidence suggests that utilizing medications, prebiotics, probiotics, and fecal microbiota transplantation (FMT) to manipulate the microbiome could be a viable method for treating NAFLD.
