IBS is not simply a problem with your digestive system. Your gut and brain are in constant communication through what is known as the gut-brain connection.
This means that what you are feeling emotionally can influence your digestive system, and what is happening in your gut can affect how you feel emotionally.
When you are stressed, anxious or worried, your nervous system can become more alert. For someone with IBS, this may affect how the gut moves, how sensitive it feels and how strongly you notice digestive sensations.
Over time, this can become a frustrating cycle:
Symptoms › worry › increased alertness › greater sensitivity › more symptoms › more worry.
This doesn't mean that your symptoms are “all in your head”. IBS symptoms are real. Rather, it recognises that the brain and digestive system are closely connected and can influence one another.
