Po, means feces; secret, sound “bi” with “closed”, meaning closed and impassable. Dictionary explains “constipation” as “less frequent defecation, dry feces.” The Modern Chinese Dictionary explains it as “dry feces, a symptom of difficult and infrequent bowel movements, also known as constipation”. Many patients do not take constipation seriously, in fact, the intestinal tract is like the human body’s “sewer”, mainly responsible for the body’s dirty work. Once the blockage occurs, the stool is retained in the intestine for a long time, which may cause acute or chronic constipation. Therefore, it is necessary to further improve the understanding of constipation. 1, what is constipation medically speaking, constipation includes symptoms such as prolonged interval between bowel movements, dry feces, prolonged bowel movement, difficulty in defecation, small amount of fecal matter per bowel movement, and incomplete bowel movement. As the concept of constipation is complex, there is no standardized criteria. Therefore, our understanding of constipation should know the following points: constipation is a special symptom, understand the original bowel habits, pay attention to the length of the disease. 2. Is constipation a disease? Constipation is not a disease, but a symptom of many diseases, different patients have different meanings. It includes: too little stool, too hard, difficult to pass; constipation combined with some symptoms, such as inability to force defecation, rectal distension, incomplete defecation or the need to use manipulation to help; less than 2-3 times within 7 days of the number of bowel movements. When constipation is said to be a disease, it often refers to functional constipation. However, constipation in Chinese medicine is as a disease. 3. How many bowel movements are normal?
