microbial gut-brain interactions

Microbial gut-brain interactions refer to the bidirectional communication between the microorganisms in our digestive system and our brain. The gut hosts trillions of bacteria that produce signals—such as chemicals and hormones—that can influence mood, stress, and cognitive functions. Conversely, the brain can affect gut bacteria through stress and other signals. This complex dialogue helps regulate digestion, immune responses, and mental health. Understanding these interactions highlights how gut health is interconnected with overall well-being, emphasizing that maintaining a balanced microbiome may support both physical and mental health.
