Your gut and brain are constantly communicating—and the vagus nerve is the key link.
What Is the Gut-Brain Axis?
This connection allows signals to travel between your digestive system and brain.
The vagus nerve helps regulate:
- Digestion
- Inflammation
- Gut motility
The vagus nerve also plays a key role in anxiety and stress regulation, not just digestion. When vagal tone is low, it can affect both mood and gut function at the same time.
If you want to understand this connection in more detail, I cover it here in my article on vagus nerve stimulation for stress relief.

The Stress–Gut Connection
Low vagal tone can lead to:
- Bloating
- IBS symptoms
- Poor digestion
Chronic stress weakens this connection.
Which can:
- Slow digestion
- Disrupt gut bacteria
- Increase intestinal permeability (“leaky gut”)
This then leads to the symptoms listed above, such as bloating.
This is why stress management is essential for gut health.

Supporting the Vagus Nerve Through Nutrition
You can support vagal function with:
- Omega-3 fatty acids
- Polyphenol-rich foods
- Fermented foods (if tolerated)
- Magnesium-rich foods

Alongside this, tools that support vagal tone—such as vagus nerve stimulation devices — can help improve communication between the gut and brain.
