Constipation might happen from a huge buildup of dry or hard waste in your bowels. It is one of the most occurring digestive problems that affect almost 2 million people in America. Constipation might occur for various reasons but the two most occurring reasons are not consuming sufficient fiber or not attaining sufficient fluids. Too little fiber or water makes your stool more difficult to pass and become harder. Slow-moving, hard waste puts more pressure on the colon that might be the reason for abdominal pain.
