Constipation is a condition often seen in children. Constipation is often associated with impaired quality of life of the child and of great concern among parents. Despite the fact that both diagnosis and treatment is a simple task, it is often seen that the treatment fails, and many children are referred to a pediatric ward for specialized treatment.

There is currently little research on the subject and treatment is therefore based on expert knowledge rather than scientific research.

The study objective is to identify the most effective and least stressful treatment of children with constipation for both families and the health care system.

The following will be tested:

Does treatment of constipation in children require specialized knowledge and extensive resources or can the treatment be simplified?

The results from this study are expected to form the basis for a evidence based treatment of children with constipation.
