Irritable Bowel Syndrome Question?

I have been diagnosed with IBS recently. Although colonoscopy and other tests came normal, it hardly means I am alright. I suffer a lot from chronic abdominal pains, constipation, diarrhea, food reactions, etc etc.

I know for sure that eating some foods deteriorates my condition, especially wheat. Wheat products produce stomach pains and they irritate me a lot. But the gastro-entrologist says I should eat wheat products because they contain fiber in it.

However high fiber foods irritates my stomach and causes me to have stomach pains. Fiber irritates my gastro-intestinal system a lot, but then if I don't eat fiber i will get constipated. What to do in such situation?

If i eat fiber, my intestines are irritated and if I don't I am constipated. how to resolve this issue?

I understand your situation completely! I had a similar situation, one Dr. told me "eat as much fiber as possible!" which sent my intestines into an uproar, so a different Dr. told me, "avoid fiber at all costs!" !!! Confusing to say the least! The best thing for you to do is to follow the "elimination diet" which is designed to avoid any foods that may trigger irritating or allergic responses that worsen or cause your symptoms. It is important to follow the diet very carefully and be sure to check all food labels, even condiments, to look for ingredients that might irritate you. After following the diet for a month you are meant to add back in foods that you suspect cause problems for you ONE at a time. It takes time and effort but will be well worth the end result which is to minimize or even stop your symptoms all together. I find it odd that your gastroenterologist told you to eat wheat if you know it triggers your symptoms. There are so many alternatives to wheat! Fiber can be found in many sources that may be less irritating to your intestines, fresh fruits, oatmeal, whole grain brown rice......combined with drinking lots of water and being sure to get some daily exercise (even a 20 minute walk in the morning) will keep you from becoming constipated. Good luck.

it could be something besides IBS.
but if it IS ibs, it might just be the way your body handles stress.
and while you may not consciously be stressed, your body itself may be (like mine, i have this problem) so what helps is
every day i take a stress relief complex. its a product from shaklee containing L-Theanine, Ashwaganha, Beta sitosterol, and L-Tyrosine.
so if you can get your hands on this or a supplement containing these compounds, give it a try, and if it helps a little, try combining it with some Imodium or any other pills claiming to "increase/improve digestive health/regularity"

i hope i was some help.

Have you tried an antidepressant? Anxiety causes a lot of ibs and antidepressants usually help a lot. Even if you don't think you are anxious, antidepressants help. They regulate serotonin not just in the brain. The intestines depend on serotonin also.
