According to a division of the National Institutes of Health, constipation is defined as having less than 3 bowel movements a week. In addition, stool is usually hard, dry, and difficult to eliminate.

The 3 most common causes of constipation are lack of fiber in the diet, not getting enough fluids, and insufficient exercise. Some medical conditions or an illness can also cause constipation.

There are simple things you can do to help prevent constipation. Be sure to eat a well-balanced diet that includes enough fiber, drink plenty of fluids, and get active every day.

Your choice of laxative to treat constipation should be guided by personal preference or a doctor’s recommendation. Some things to consider when choosing one for your need are how it is administered and how quickly it works.
