- Constipation can be defined as challenging or infrequent bowel movements.
- Normal bowel movement frequency ranges widely, from three times daily up to once or twice every week.
- Going more than three days without having a bowel movement can be considered too long and may result in harder, more difficult-to-pass stools.
- Constipation typically stems from functional issues within the bowels themselves rather than any anatomical defects that might exist.
