Constipation causes: Common causes of constipation are dietary. Sit down and write out all the foods you have eaten over the past week or two. Eliminate all the grains: rice,barley,oats; also milk,bananas,apples. Within a few days your stool should soften dramatically. You don't want to become laxative dependent. You may have megacolon. See a gastroenterologist.
