if the problem persists more than a couple weeks, return to the doctor. a change in fluid intake and fiber and exercise maybe all you need, however, the doctor may want to take that next step to the colonoscopy. prostate problems can aggrivate bowel regularity, so if you have prostitis you may need an antibiotic or a drug that can help shrink the size of the prostate (they have them now).. only the doctor will be able to assess this situation. if you have tried the dietary changes, definately seek professional help
