Traumatic brain injury (TBI) is a common disease with a high rate of death and disability, which poses a serious threat to human health; thus, the effective treatment of TBI has been a high priority. The brain-gut-microbial (BGM) axis, as a bidirectional communication network for information exchange between the brain and gut, plays a crucial role in neurological diseases. This article comprehensively explores the interrelationship between the BGM axis and TBI, including its physiological effects, basic pathophysiology, and potential therapeutic strategies. It highlights how the bidirectional regulatory pathways of the BGM axis could provide new insights into clinical TBI treatment and underscores the necessity for advanced research and development of innovative clinical treatments for TBI.

Background: Despite significant advances in the understanding of the pathogenesis of obesity and influencing factors, its prevalence continues to increase at an alarming rate. Social determinants of health (SDOH) encompass a broad range of psychosocial and environmental factors, including economic stability, education, access to healthcare, social support, isolation, neighborhood disadvantage, discrimination, early life adversity, and stress, all of which have been recognized to significantly increase the risk of obesity.
Aim: This review aims to elucidate the intricate relationship between SDOH and biological mechanisms related to the brain-gut-microbiome (BGM) system that lead to altered eating behaviors and obesity.

The brain-gut-microbiome (BGM) axis regulates interoception, metabolism, and immunity, with dysfunction linked to IBS, obesity, and mood disorders. Ultra-high-field (UHF) MRI advances neural imaging, enhancing resolution of vagal and spinal circuits mediating gut-brain communication. UHF enables real-time tracking of interventions like vagus nerve stimulation and probiotics, linking microbiome shifts to neural adaptations.

Convergent data across species paint a compelling picture of the critical role of the gut and its resident microbiota in several brain functions and disorders. The chemicals mediating communication along these sophisticated highways of the brain-gut-microbiome (BGM) axis include both microbiota metabolites and classical neurotransmitters. Amongst the latter, GABA is fundamental to brain function, mediating most neuronal inhibition.
