Constipation occurs when bowel movements become less frequent and bowel movements become difficult to evacuate. It occurs most often due to changes in diet or routine, or due to inadequate fiber intake. You should call your doctor if you have severe pain, blood in your stool, or constipation that lasts longer than three weeks. However, spending more than 3 or more days without one is often too long.
After 3 days, the stool becomes harder and harder to evacuate. This means that an abnormal bowel movement schedule can vary depending on how often you defecate. Not defecating even for three days can be extremely unusual or unusual for some people. De Latour stated that eight days without defecating are worrying for most people.
While occasional constipation is very common, some people experience chronic constipation that can interfere with their ability to perform their daily tasks. Chronic constipation can also cause people to work too hard to defecate.
