Your Gut and Mood Are More Connected Than You Think

If you’ve ever had “butterflies” when nervous or a “gut feeling” about something, you’ve felt the link between your gut and your emotions. But the connection goes even deeper than that.

Your gut contains over 500 million neurons and sends more messages to your brain than your brain sends to it. That’s why it’s often called your “second brain.” When your gut is out of balance—whether from stress, diet, trauma, illness, or antibiotics—it can disrupt your mood, focus, and energy.

An imbalanced gut microbiome can lead to increased anxiety, depression, brain fog, and even sleep issues. This is especially important for those living with chronic illness, autoimmune conditions, or trauma histories. Nervous system dysregulation can inflame the gut, and gut inflammation can keep the nervous system stuck in survival mode.

It’s a two-way street—and healing one supports the other.

When your gut is inflamed or your microbiome is imbalanced, the vagus nerve (which connects the gut and brain) can become less active. This weakens your body’s ability to move out of fight, flight, or freeze responses and into a regulated, calm state. That’s why healing the gut isn’t just a physical process—it’s an emotional one too.

Somatic therapy, nervous system education, and trauma-informed care can help bring regulation back to the body, creating the conditions your gut needs to heal. Likewise, improving gut health through nutrition, rest, and nervous system work can support your mental health and emotional resilience.

At Integrative Healing, we understand the complex connection between gut health and mood. We support clients who are navigating both physical and emotional symptoms—without separating the two. If you feel like you’ve tried everything and still don’t feel better, this might be the missing link.
