I can''t poo unless I take dulcolax. I eat LOTS of fiber everyday, drink 3 lt of water, and work out. What should I do?

BM frequency. Bowel movements may occur, and be considered normal, anywhere from three times a day to three per week. You should see a gastroenterologist to be sure there is nothing causing a blockage. If all's clear, you may need to do bowel retraining to help decrease your dependence on medication. If you have chronic constipation, there are medications that need to be monitored, but may help.
