Notions of bowel habits lie in the eyes of the beholders. Constipation is one of the most difficult gut symptoms to define. Patients, physicians, and physiologists have different views of the condition. The difficulty lies in the many, but variably present, features of constipation.

Many manage happily with less, while others within that range are decidedly uncomfortable with what they believe is constipation. Reviewed and updated 2021.
