Physicians are also beginning to understand the direct connection between the brain and the gut1. This ‘gut-brain axis’ is a superhighway consisting of the vagus nerve,1 which runs from the brain to the gut, where nerve signals are sent and received. Communication also occurs via a series of hormones1 and other chemicals, some of which are released8 by gut bacteria, aka. the microbiota.
Because gut stress affects your whole body, this two-way network is essential for healthy body functioning, but sometimes things get out of balance. Emotions linked to stress can cause problems in the gut,1 while problems in the gut can lead to imbalances that eventually affect the brain.10
Look out for these symptoms of an imbalanced gut-brain connection:
- Heartburn or acid regurgitation1, 4
- Chronic pain relating to eating (dyspepsia) 1
- Feeling uncomfortably full during or after a meal, gastric pain or burning1,5
- Bloating and/or cramping (which may be relieved by defecation)1, 5
- Abdominal pain associated with constipation or diarrhea1, 5
- Lower abdominal pain linked to bloody diarrhea (i.e., symptoms of inflammatory bowel disease)1, 10
If these problems are not treated, there can be long-term health consequences,1 such as increased sensitivity to abdominal pain.1
