My sister in law has complained about that for 25 years ! She has complained about that more than she complained about her cancer. 

It's my understanding, that one should eat a lot of fiber and drink water, and try to stay away from stressful situations.  My g. friend claims that ever time she eat both veggies and fruit together, that she gets diarrhea.

good advice from everyone, although you should keep well clear of processed foods especially fast "foods" (or crap as its usually called) and cut out sugar as its bad for you anyway, use honey instead. I have been devouring fermented foods over the last few years and the difference in digestive activity is great, i can tell the time by my daily movements :-). fermented food are full of flora and fauna that our body needs as humans are basically meat bubbles containing water and billions and billions of bacteria, so we need to keep the symbiotic relationship a happy one. also try kombucha tea, a little at first as you may have a  urgent explosion if you gulp it down, work your way up to a beer bottle size a day and you'll feel better within a month, its working for me :-)

The treatment for IBS is long term process. Trigger factors should be identified and treated. Specialist dietician can help you with that. I would suggest you to get an appointment gastroenterologist consultant .
