Can an intense anxiety attack cause symptoms exactly like a stomach flu?

Hi! I’m coming down from a very intense anxiety attack caused by (non-GI related) health concerns that might actually be something scary, and as I was having the attack I started to feel extremely nauseous and my heart was skipping beats (which is something that happens a lot when I’m severely anxious) but THIS time it was also accompanied by the burning, bubbling feeling you get in your gut when you have diarrhoea and (EXTREMELY GROSS AND TMI) gas that weird heavy, lingering quality and smell you get with a virus. I’ve never had this combination of symptoms before and I was wondering if this is still anxiety or whether I somehow came down with something EXACTLY at the same time? The attack did start as I was eating dinner so I’m not sure if that’s relevant. Sorry about the gross question but it’s kinda freaking me out even more!
