Hello MCAS Community!
Have you ever had butterflies in your stomach when you’re nervous?
Or noticed that a stressful situation, day, or week can quickly turn into digestive problems?
And have you ever eaten the “wrong” food and ended up with a big flare of your MCAS symptoms?
These are all examples of how closely connected your gut, microbiome, immune system, and nervous system are.
**For many people with mast cell activation syndrome (MCAS), that communication can be pretty clear. And it shows up as symptoms. **
While you can’t take every stressor out of your life, you can support the systems that carry and respond to those signals.
In this post, you’ll learn:
What the gut-brain axis is
Paths it uses to communicate
How gut bacteria contribute to the conversation
How mast cells are involved in the connection
Gentle ways to consider supporting it all

What Is the Gut-Brain Axis (and Where do Mast Cells Fit In)?
Your gut and your brain talk to each other all day long.

About 80% of your vagus nerve fibers carry information to your brain. But your gut and brain communicate through several different routes.
Let’s take a look at a few of these conversation pathways.
