- Medication Group (Control) Patients in this group will be monitored on a weekly basis by a pediatric gastroenterologist, who will be unaware of which patients belonged to which treatment group, since patients were only receiving clinical follow-up. All patients will be prescribed a laxative (magnesium hydroxide), for which the dosage varied according to individual needs (a minimum of 2 ml/kg), and will receive guidance regarding fiber-rich foods, water and toilet training, under the same conditions as patients in the intervention group.
