Hi Marcia,
First I just want to say that I'm so sorry you're dealing with a stomach flu right now and I hope it doesn't last much longer. Of course, if you haven't already, it's probably worth asking a doctor this same question just to make sure what you're dealing with is normal, but I also wanted to share a blog post that one of our contributors wrote a few months ago on this topic. It sounds like he also deals with worse symptoms from a stomach flu due to IBD. Here's the link if you're interested and I'm sending positive thoughts your way: https://inflammatoryboweldisease.net/living/normal-stomach-bug/

Yes. I believe stomach flu can last longer and become more severe with IBD.
I once got food poisoning in Costa Rica. I shared a meal with a friend and his food poisoning was not bad at all. A day at worst.
Mine was five days and was very severe. That's just one example of how a flu or stomach poisoning can exacerbate your underlying condition and wreak havoc on your body.
