Bowel movement. Figure out the problem.

I've been suffering from irregular bowel movement for the last 5 years.Earlier it was not so chronic,but now it is out of control.Mornings are nightmare for me .I have to attend nature calls at least for 4-5 times every morning,due to which other spheres of life have been badly affected.I retire to bed early(most probably by 11 pm) and woke up at 5 am , and does regular exercises like brisk walk,stretching etc in open area(ground) and in the evening plays outdoor games .Also , i don't smoke or drink either and eat simple food .In afternoon i don't have lunch due to workplace remote location,but i regularly have breakfast and dinner,in addition to that i have fresh fruit juices.But despite of following simple food regime and lifestyle it is not giving me the desired results.Kindly help me out to figure out the problem.
