Hey Torrie, I'm so sorry to hear that your daughter is going through all of this. It's a painful and sometimes embarrassing problem for adults to deal with (I'm a single women in her 30's and I've got a few dating nightmare stories!) I can't imagine what it's like to have all these difficulties at 16 when your biggest worry should be who's going to invite you to prom! Anyway, I have a few suggestions too. Definitely work the peppermint teach, it's a god-send for nausea. Also, see if you can find Aloe Vera suppliments, I have a friend with IBS who swears by them. I think they sell them at Walmart. She could try two or three tabs a day. Another "alternative" method is to try yoga and meditation. It sounds wacky but I did an IBS trial where they had us do these things along with drug treatment and they really seemed to work. Sometimes you can lessen symptoms with mind over matter. It's kind of like lamaz for IBS sufferers. I find that I make my symptoms much worse if I'm concentrating on them, so having a distraction or being able to "leave your body" for a few minutes with meditation techniques seems to stop me from panicking (thus making the situation worse). On the medical side, has she had an ultrasound to rule out gallstones or gallbladder issues? I had some success with a medication called Desiperamine, which is an anti-depressant, but for some it has unpleasant side-effects. Unfortunately it seems this is all a trial and error process, but I was diagnosed with IBS about 18 years ago and we've made a LOT of progress since then and we're continuing to move forward with new treatments. Good luck, I'll be praying for Kayla.
