This is an updated guideline from the BGS on IBS. It was published in June 2021. The last guideline they published was in 2007. NICE also has a guideline on IBS, which was published in 2008, but which has been updated several times since then. This is much more detailed and is, I think, therefore more useful.
If you are interested in the pathophysiology of IBS, then a 10 minute read through that section of the guideline is really very useful. I will definitely be changing how I talk to patients with IBS based upon my reading of this.
I am going to outline what is new or what I found interesting in this guideline, and then going to do a summary of the guideline.
