If you have constipation, it’s usually because your stools are moving too slowly through your colon. Too much water is absorbed from the colon and your stools end up hard, dry and therefore difficult to pass.
Normally, your poo is about three quarters water, with the rest being mostly undigested solids including fats, protein and food residues.
What causes constipation?
Constipation in adults may be caused by lifestyle factors, medical reasons or as a side effect of certain medications.
Common lifestyle causes of constipation include:
- Low fluid intake
- Low fibre intake
- Lack of regular exercise
- Ignoring the urge to go
- A change in routine or diet
- A period of illness (particularly when bed rest is required)
