This is absolutely the ONLY reason and the only type of situation where I am actually not glad, but OK with having IBS. It's my go to excuse, that and the actual PCOS that I have to avoid food bullying at family gatherings. Maybe you can just start saying you've been recently diagnosed and eating that would upset your very delicate system or just say you have "stomach issues". I don't know. I'm normally too honest, not one for lying but good grief this constant trying to push food on people is beyond ridiculous.
