Up to 10% of children will be constipated at any given time. Other factors include the following:
- Constipation is slightly more common in boys.
- Children who have developmental delays, behavioral issues or problems affecting the anus or rectum may suffer from chronic (long-term) constipation.
- Older children and teens may become constipated if their diet does not include enough high-fiber foods and water.
- Children who are at toilet training-age may be holding in their stool.
