Constipation in children can be caused by diet, lack of exercise, toilet training issues, and underlying medical conditions. Dietary management of childhood constipation focuses on education of parents, providing relief to the child, and modifying the child's diet. This involves increasing fiber intake through fruits, vegetables and whole grains, drinking plenty of fluids, limiting junk food and dairy, and establishing regular eating and exercise routines. Behavioral changes like scheduled toilet time and counseling can also help manage chronic constipation.
