Irritable Bowel Syndrome Guide: The Brain-Gut Axis.
The gut has its own network nervous system. It is called the Enteric Nervous System. It has more nerve cells than the Spinal Cord. The Enteric Nervous System is connected to the Brain via the Vagus nerve which is the tenth cranial nerve.
This interconnection is part of the Brain-Gut Axis and through this Axis, events in the gut can be linked directly to Brain activity.
We know that anxiety, stress and depression have specific effects on the gut. Anxiety and stress can cause diarrhoea and depression can lead to constipation.
With no specific physical abnormality in sufferers with Irritable Bowel Syndrome, research is increasingly directed to the Body-Mind aspect of IBS. In Irritable Bowel Syndrome the Brain-Gut axis is faulty and to regain control of IBS it needs adjusting.
The effects of the brain function on the gut has been well documented but recent development in Brain Scans and Monitors have demonstrated that the Mid-Cingulate part of the brain Cortex is stimulated during emotional distress.
Under observation, when this part of the brain is in overdrive or being over stimulated during stress, gastro-intestinal effects develop. Patients develop spasms of abdominal pain and/or diarrhoea.
This explains why stress is an important trigger of Irritable Bowel Syndrome, and by reducing stress you are helping to control your Irritable Bowel Syndrome.
