What is Gut–Brain Axis?

Your gut and brain communicate in real time via the Gut–Brain Axis—a two-way highway connecting the enteric nervous system, microbiome, immune signals, and vagus nerve. This connection has a major influence on mood, stress, and sleep quality

Gut microbes produce neurotransmitters like serotonin and GABA, along with metabolites (e.g., short-chain fatty acids). These signals travel to the brain, helping regulate stress, mood, and sleep patterns

Stress and anxiety can disrupt gut function—hurting motility, causing cramps, bloating, or constipation .
