Constipation is a common symptom in children, accounting for about 3% of consultations in routine pediatric practice and as much as 25% in pediatric gastroenterology clinics. Constipation is defined as the passing of hard stools, with a frequency of fewer than 3 times per week. It is usually accompanied by abdominal bloating, abdominal pain and poor appetite. There are multiple factors that influence constipation, such as dietary, physical, psychological, pathological, social and environmental factors. In the theory of Traditional Chinese medicine, the bodies of children are distinguished by frail zang-fu organs, bodies and qi that are not fully developed, and weakness of the spleen, the later leading to the inability to properly metabolize and transport nutrients. The causes of childhood constipation can also be due to congenital insufficiency and improper postnatal nourishment. Treatment by traditional Chinese medicine takes into consideration the above mentioned features and modifies prescriptions according to five types of main patterns: food retention, qi stagnation, dryness-heat, qi deficiency, and blood deficiency.
