Have you ever been so anxious that your stomach started hurting? In addition to its well-known impacts on mental health, stress can also make people feel physically ill—and a new study could help explain why.  

Although it’s fairly common knowledge that the gut “talks” to the brain by releasing hormones into the bloodstream, this recent study showed the relationship going back the other way: from the brain to the gut to the immune system.  

Researchers have found that removing key glands (called Brunner’s glands) in mice, which line the walls of the small intestine, triggered inflammation and increase the chance of infection. Similar thing happens in humans who’ve had tumours removed in their gut.  

It seems that removal of these glands leads to a reduction in gut bacteria which triggers inflammation and subsequent pain.  

When the researchers took a closer look at these glands, they discovered a connection to the vagus nerve that goes from the base of the brain to the internal organs, influencing digestion, blood pressure, and even memory and mood. Fibers that connect to Brunner’s gland lead directly to a region of the brain known as the amygdala, which plays a key role in emotion and the stress response.  

Researchers found that when mice are under chronic stress their glands shut down—causing gut bacteria to dwindle and intensifying inflammation.  

The take home message: being under mental stress can lead to a painful stomach! It highlights the importance of monitoring your stress levels and keeping good gut bacteria.
