Why do I feel sick when I fancy a guy and he liked me back?

Question

Like every time I like a guy, I’m excited and attracted but when they show interest in me or when we go on dates, I get this super nauseous feeling. It makes me get a funny tummy and I feel anxious that I want to run away from it all. Then over time it subsides but then I don’t like them as much after that. 
I feel a bit broken

Answer

Have you ever considered going to a therapist about this? Do you think it could be trauma related?

Answer

Maybe you just like the feeling of the chase.

Answer

So this what my gastroenterologist told me BUT don't ever take advice from people on the internet over seeing your own doctor.
Our gut makes some chemicals/hormones related to stress (the good and not so good kinds) and anxiety. For some of us (myself included) it is overactive and creates too much at once. So, when we get anxious, happy, angry etc, we get too much of them compared to people with a normal acting gut. The effects of that in the gut is feeling nauseated, vomiting, diarrhea, bloating and overall digestive problems for several days until it goes back to normal. That's why some people puke before a presentation or have frequent bathroom visits during stressful situations or want to avoid too much social interactions even when they're positive experiences.
The things we can do to help are stress management, possibly starting medications to control our overactive gut, and having remedies and OTC medications for the symptoms when it does become overactive.
