The normal rectum of a person has a certain threshold for pressure stimulation from feces. When this threshold is reached, the person will feel the urge to defecate. When 100 ml of feces fills the rectum by 25%, or the pressure in the rectum reaches about 2.4 kPa, the urge to defecate will occur. To reach the point where a bowel movement is necessary, rectal contents and pressure must increase threefold. But whether or not to defecate ultimately depends on whether the higher-level defecation center inhibits or enhances the effect of the lower-level center.

The frequency and habits of bowel movements vary from person to person, but generally it is once a day, after breakfast. Some people have bowel movements once every 3 to 5 days or even longer, but do not feel any difficulty in defecation. There is a comfortable and pleasant feeling after defecation. Therefore, constipation, diarrhea or changes in bowel movement patterns cannot be determined solely by the number of bowel movements, but should be determined based on each person's bowel habits.

Normal people usually have bowel movements 1 to 3 times a day or 3 times a week, and 95% of healthy people have bowel movements within this range.

So as to find the cause as soon as possible and give appropriate treatment in time.
