Your gut and brain are more connected than you might think. Through what’s known as the gut-brain axis, your digestive system and brain communicate through a complex network involving the nervous system, immune system, hormones, and the trillions of microorganisms that make up the gut microbiome.
Because of this connection, gut health can play a role in mood, stress response, focus, and overall mental well-being. The gut microbiome also produces and influences compounds involved in brain function, while stress can affect digestion and the gut environment—making this relationship a two-way street.
This is one of the reasons we believe mental health should be approached from a whole-person perspective. Sleep, nutrition, movement, stress, physical health, relationships, and environment can all interact with how we think and feel, and understanding those connections can help us look beyond symptoms alone.
At Triad Functional Mental Health, we consider the many factors that may be influencing your mental well-being. If you’re interested in taking a deeper look at your mental health, visit triadstl.com to schedule your free consultation.
