What’s going on in your brain can affect what’s happening in your gut, according to new research from the University of Georgia.

Researchers analyzed the gut microbiomes of healthy adults to understand how changes in the brain can influence stomach and intestinal functioning and vice versa. 

The body breaks down food, absorbs nutrients and removes waste through the gastrointestinal tract, where it hosts trillions of helpful microbes (the gut microbiome) that support immunity and connect to the brain.

The gut is sensitive to subtle shifts in mental wellbeing, and when it’s healthy, it can reduce symptoms including stress and depression, said UGA professor and researcher Franklin West.

"You have nerves running from the brain to the gut, and they actually see the serotonin and the melatonin," West said. "So, the bacteria in your gut that you're adding through the probiotic can actually release the serotonin. So, it's literally connected to your nervous system."

Changes in bacteria are also related to diseases like cancer, heart disease and stroke, West said.
