Generally, chronic constipation refers to a stool frequency of less than three per week that lasts several months. However, the symptoms can vary to include infrequent bowel movements for weeks at a time or having difficulty passing stools.
Constipation occurs when bowel movements become difficult or less frequent. The normal length of time between bowel movements varies based on the individual. Going longer than three days without a bowel movement, after which the stool or feces become harder and more difficult to pass, is a sign of chronic constipation.
