Constipation
Constipation is difficulty passing faeces because they have become hard. It happens when faeces stay too long in the large intestine and too much water is absorbed from them.
- Too little fibre in the food eaten.
- Not drinking enough water.
- Putting off going to the toilet.
- Some medicines taken for other illnesses.
If it goes on
Straining can tear the lining of the rectum and cause bleeding, and continued constipation can lead to piles.
