The classification of TCM syndromes of pediatric constipation was obtained by factor analysis and cluster analysis. Results：The statistical results shown 87 cases of simple syndrome type, a- mong them, 19 cases of dyspepsia internal heat, 31 cases of yangming dryness-heat, 37 cases of depletion of fluid causing intestine-dryness;30 cases of complex syndromes, among them, 12 cases of the dyspepsia internal heat with yangming dryness-heat, 5 cases of yangming dryness-heat with intestine-dryness due to consumption of fluid, 7 cases of dyspepsia internal heat with intestine-dryness due to consumption of fluid, 6 cases of dyspepsia internal heat, yangming dryness-heat with intestine-dryness due to consumption of fluid; 29 cases of no syndrome type. Conclusion： To use mathematical methods for syndromes classification and clinical diagnosis of syndromes is better in line with the practice. TCM syndromes of pediatric constipation can be divided into dyspepsia internal heat, yangming dryness-heat and intestine-dryness due to consumption of fluid.
