Im 21 yrs old and never have any GI problems until this year. Twice this year I had food poisoning symptoms d and vommiting, both times it took about a week for my stomach to settle and for my BM's to be regular. At the beginning of July I had sushi and within 2 hrs I had horrible D all night long. Ever since then my gut/belly button area has been hurting. First my doc took an x-ray and said i had a lot of stool in my gut and i was told to take lomitol for a week and a laxative for another week. I couldn't take the lomitol for more then a day because it made my pains worse, so I switched to the laxative which of course just gave me D. Next i went to the ER one night cause my stomach was hurting really bad and I had seen blood in my stool. They prescribed antibiotics "incase" I had a bug. While I was on those along with Bentyl I started to feel a little bit better. And even a week after i was feeling ok, but then back came the D. This whole month I haven't had a "formed" stool. So i went to see a GI specialist and he said it didn't sound like IBS cause usually people with IBS have more of a history of gut problems their whole life...my regular doctor said it might be IBS though...The GI doc said he is going to do a upper endoscopy and a colonoscopy on Tuesday. I'm really nervous about both procedurs but I just want to know whats going on. My bloodwork always comes back clear, and I'm still waiting for my stool results. Does this sound like IBS? Or bad luck with food this year? My gut hurts all day and is definetly a lot worse the earlier part of the day, and then whenever I do have a BM the pain is bad I feel like I'm going to pass out...any tips or advie?
