Abnormality of bowel transit that causes infrequent bowel movements (less than three per week), usually characterised by sparse and hard stools. It is a common reason for seeking medical attention in children and adolescents.
The main cause is a slowing of bowel transit and a diet with little or no fibre; some diseases also promote it.
Diagnosis is clinical, by interview and clinical examination. Patients should be asked about their diet, medication and co-morbidities. Depending on the symptoms, tests may be needed to determine the cause: abdominal X-ray, colonoscopy, etc.
Treatment depends on the underlying cause. In most cases, adding fibre to the diet, drinking plenty of water and regular exercise are recommended.
