The Vicious Circle – IBS and Stress

The link between irritable bowel syndrome and stress, and what to do

Originally published on: June 8th, 2022. Last modified on December 8th, 2022

A recent worldwide study has revealed that there is a close link between having irritable bowel syndrome and common mental health conditions such as anxiety and depression.

The research, which included over 40 institutions across the UK and Spain examined nearly 50,000 patients with IBS and found that IBS symptoms are caused by the same biological processes as anxiety1.

This of course seems to make sense as there is an overlap in the symptoms of both anxiety and IBS including gastrointestinal disturbances, avoiding social situations, feeling panicked and embarrassment. 

The link between Stress and IBS

Irritable bowel syndrome has long been connected to our mental wellbeing with stress being a well known trigger. It is often described as a vicious cycle as high levels of stress can trigger IBS symptoms (also known as stress induced IBS) but then having IBS symptoms can lead to high levels of stress, anxiety and depression.

The above image describes the vicious circle of anxiety and how a trigger – which might be a traumatic life event, infection or even both – can lead to changes in your bowel function. This can go on to cause bowel symptoms and changes to daily routines or eating habits as you try to cope. The concerns, which can be substantial, then start to disrupt our work or social lives, and then anxiety or depression can creep in.

The IBS Network have a useful factsheet about Stress, Trauma and IBS which puts this into context, which you can download from their website- this is also listed at the end of this article2.

If this resonates with you, the good news is that there is help available to help manage your symptoms and stress.

Martha Highton of NHS IAPT (Improving Access to Psychological Therapies) tells us:

Many symptoms of panic disorder and IBS are similar including avoidance of social situations, embarrassment and the overwhelming need to leave certain environments. Our minds and stomachs are strongly linked, meaning that often if there is an issue with one it often will affect the other.

Similarly if people are suffering with problems relating to their bowel or bladders, this will often cause symptoms of anxiety or depression.
