The Gut & Brain Connection
Stress is part of everyday life, but while we often focus on its impact on mental wellbeing, we shouldn’t overlook its effect on the gut. The gut-brain axis, the two-way communication between the gut and brain, plays a key role in how we respond to stress. When stress levels rise, the body releases cortisol, triggering a ‘fight or flight’ response, also known as activation of the sympathetic nervous system, which draws blood flow away from the gut. This diversion of blood disrupts the gut’s normal rhythm, slowing down digestion and potentially contributing to inflammation. For many people, stress can show up in the gut as bloating, cramps, nausea, or changes in bowel habits (including urgency or constipation), even if you’re otherwise healthy. Over time, this can alter gut bacteria and impact how effectively the gut and brain communicate.
