Constipation is very common in children and can be characterized by decreased frequency of bowel movements (≤2 times/week); dry, hard stools; difficult (laborious, time-consuming) bowel movements; painful bowel movements; and a sense of incomplete bowel movements. The prevalence of constipation in children is reported to be 0.7% – 29.6% (median 12%), 90% of which are functional constipation. The diagnosis of functional constipation in children is mainly based on the Rome III criteria. The North American Society for Paediatric Gastroenterology and Hepatology and Nutrition developed guidelines for the management of functional constipation in children in 1999, which were updated in 2006 and 2014; the National Institute for Health and Clinical Excellence (NICE) in the UK The treatment strategy for functional constipation in children mainly includes basic treatment, pharmacological treatment, behavioral treatment, surgical treatment and follow-up. Basic treatment is based on family education, dietary modification and lifestyle changes. It is important to drink sufficient amount of water (including water and juice in food), balanced diet (encourage breastfeeding and increase the intake of dietary fiber), appropriate exercise, and reasonable toilet training (for children over 4 years old, toileting after each meal for 5-10 min per day). If basic treatment does not work for 2 weeks, medication should be started. Medication is preferred to oral osmotic laxatives (polyethylene glycol or lactulose) or rectal laxative, and continues for 3 Surgical treatment is indicated for refractory constipation, and if medication is ineffective, chronic constipation or manual laxation is required, cathartic enema (cecum stoma) or sigmoid colectomy can be performed. The treatment of constipation is long-term and usually easy to recur, parents may seek treatment in multiple hospitals, so follow-up is particularly important. Family education and health education should be emphasized to guide a reasonable diet and lifestyle, and the application of non-pharmacological therapies should be emphasized. We should also pay attention to the warning signs and symptoms of constipation and correct the diagnosis in a timely manner. In addition, multidisciplinary association should be strengthened to improve the diagnosis and treatment of functional constipation in children.
