Defecation should be regular, if often delayed defecation time, can make the defecation reflex weakened, causing habitual constipation. Therefore, to treat constipation, we need to change the bad defecation habits and rebuild the normal defecation reflex and normal defecation function. First of all, develop the habit of regular defecation, whether or not the intention to defecate, it is best to squat once in a fixed period of time. This time should be chosen in the morning after waking up or other time that you think is appropriate. Of course, the formality is not helpful. In the bowel movement to focus on the bowel movement, do not do other things such as reading books, listening to music, etc.. By developing the habit of regular bowel movements, you can increase the normal bowel reflex. Secondly, do not artificially control defecation, and defecate immediately when the feces enters the rectum and produces the urge to defecate. For people who have habitual constipation, any urge to defecate, even if it is very weak, is valuable. Once the urge disappears, it is not so easy to have it again. If you ignore the urge to defecate and do not defecate in time, the urge to defecate will be suppressed over time, and if the stool stays in the large intestine for too long, too much water will be absorbed and the stool will become dry, and as a result, the stool will not be easily discharged.
