Common Causes of Constipation. To understand how to prevent constipation, it helps to know what causes it. As food passes through your colon, your body absorbs the water from it, and what's left forms into stool. Your muscles move it through the colon to the rectum, where you pass it. When this movement slows down, your colon draws too much water. Stools get dry and hard to pass, causing constipation.
