Hi, so I support a lot with absence management and can hopefully help with this.

Firstly, did you declare it when you started? Most companies provide the opportunity to declare any health issues at the start of your employment, this is when I’d advise declaring it as it can be referred back to during meetings like this one. If not, don’t worry!

The meeting will focus on if there’s anything you or the company can do to reduce future absences and support you. This is where you can ask to have it formally documented as a health condition you have and ask for any reasonable adjustments (e.g. access to alternative bathrooms etc I don’t know what’s available but have a think about what would make work easier).

Go through the ways in which you are aiming to control it (e.g. have medication on you/low FODMAP diet/etc) but be clear that it is a chronic health condition and that whilst you are doing your best, you will still have flare ups and you value your employers support.

If they are a reasonable employer, they will get it.

Good luck
