Hi, im 16 as well and Im dealing with IBS. I was just diagnosed a couple months ago and im still trying to figure out how to control my symptoms. I'm actually home today because I wasn't feeling well and thought I'd try to find some answers. The gas and bloating is the one thing that makes me really anxious about being in class. Last year my noises were really loud and it was definitely traumatic. I dont know if your stomach cramps but my gastroenterologist (check spelling) gave me Hyomax, a stomach relaxer. All it goes is relax your stomach so it doesn't spaz out and contract or whatever. I take it at night and it reallyy helps with cramps. She gave me Culturelle for the diarrhea and constipation, but it gave me gas. What helps me out in school is eating early so i have time to go to the bathroom before school. Also, when i get really hungry at school it gives me even more gas, so i eat a bite of my peanut butter sandwich (on gluten free bread b/c i also have celiac disease) whenever i feel even a little hungry. I also have become really good friends with the nurses at my school. They have a bathroom in there that's private (since "relieveing" myself in the public girls room is almost impossible) and I go there whenever I feel like I have to go to the bathroom or my gas is bothering me. Theyve given me a permanent pass so the teacher doesnt write one every time i go down there, and all i have to do is raise my hand and the teacher will quietly excuse me. I know kids wonder why I leave all the time but its much better than sitting in class uncomfortable and making noises. BUt like i said before, i still get gas and i get anxious in class, and i would love if someone knew any good medicines that made this stop ( ive tried Beano, Gas-X, and Tums but they made it worse).Idk if this will help but these are the foods that bother me( mostly because theyre acidic or have caffine):- milk, barbeque sauce, tomato sauce, ketchup, green veggies, fruit, fruit juice, tea, chocolate, and coffeeI'm not saying you have to eliminate these all, but maybe try taking out a couple n see what happensI hope this helps!
