Why do I get constipation for no reason?

It sounds like the problem is psychological - only thing to do is to set aside large blocks of time to spend in the bathroom. (I'm sure you'll think of something else to do whilst waiting for your intestines to come back into action again! Or if you genuinely are feeling constipated, why not just take an enema and get it over with)

Are your stools thin or flat ? then it could be irritable bowel syndrome (ibs).. a main reason for IBS could be stress.. stress so i agree with susan friar that the problem could be psychological so even if you eat a ton of fruits the problem may still exist... but one thing you could try is some yoga for constipation...there are certain yoga positions that can cure constipation and also certain breathing techniques.. Another main reason for constipation is lack of activity, if you are not doing enough exercises that can also be a reason.. Il share a video in the source on " yoga poses for constipation" that could help.. cheers
