[|Human|] I am sadiq from bangalore, india. I came to malvern, PA, USA 3 weeks back for work. I went to ocean city beach today (saturday) with my friends. After 2 hours of swimming in the beach, when we started, I fainted for couple of minutes, then after drinking ice water, i got it ready. Before entering to beach, i had chicken cheese pizza (First time, i am eating pizza from usa). While returning, I vomitted all pizza and feeling ok. When reached hotel, i got fainted again and managed to go to hotel. When I was in the beach, before fainting, my body was completely itching in the shoulder and i continued to play in the beach and then started leaving there. When i got fainted, I am able to hear what my friends are talking and able to answer them. I am confused, what could be the problem? This never happened before in india and this is my first trip to usa.
[|AI|]  Hi, I don't think, so it could be due to food allergy. As u swimmer for 2 hours and then took ice water, cheese pizza and then the fainting episodes and finally vomited out. This fainting episodes is known as occasional syncope, and it can occur without reason or just stomach trouble, excess of exercise or any other small reason.u might have stomach upset as u said u vomited.these problems usually subsides by itself but still u can consult gastroenterologist for further evaluation
