The idea of “treating disease before its onset” is an important part of traditional Chinese medicine.Its core idea is divided into three parts，namely，“precautions before occurrence”，“controlling the development of existing disease”，and “prevention of recurrence of the disease”.“Precautions before occurrence” emphasizes prevention and avoiding diseases.“Controlling development of existing disease” emphasizes that the disease needs treating early，preventing progression，and avoiding other viscera involvement.“Prevention of recurrence of the disease” emphasizes regulation when the disease has just recovered，thus preventing disease recurrence.The idea of “treating disease before its onset” plays a crucial role in the prevention and treatment of chronic constipation.Intervention in various stages of patients with chronic constipation through various means is of great significance to improve the quality of life of patients.
