L.T.
I've had IBS for probably over 20yrs now on and off...it comes and goes depending on my stress level. I can go 5,6,7 yrs without any problems and then it will surface up due to stress and I will battle it for about a year seems like and then poof it's gone. I haven't had any problems in the last 4 yrs but when it does surface I have to watch my diet...stay away from "trigger" foods that aggrevates the IBS and try to get rid of the root of my stress. I've been to several doctors...all they ever wanted to do for me was prescribe me an anti-depressant which I was not in favor of...I asked the doctors why I should take an anti depressant when I'm not depressed...stressed maybe but never depressed. They kept explaining to me that there are two hormones that live in your stomach and when I stress it triggers those hormones to act up...the anti depressant is suppose to relax those hormones and help control the IBS. I still didn't like the idea of going on a med so I chose to deal with it and take control of my diet along with finding the root of my stress and fixing it!!! I'm pretty sure there's no real cure for IBS it just involves a lot of research on what your body likes and doesn't like...
I'm sure I'm not alot of help and know this is VERY frustrating. Hopefully you find what works for you. Another idea however is to have a colonoscopy just to make sure everything is ok. I had one done at the age of 25 and low and behold he found 2 parasites in me...we don't know how I got them...he said it could have been from sushi or it could have been from my trip to Tahiti...who knows but I'm glad they found them and we took care of that issue.
I wish you the best of luck and hang in there.
