What causes constipation
Constipation means infrequent or difficult bowel movements. Most people experience occasional problems with normal bowel movements. But if constipation lasts for weeks and months on end, it is termed as chronic.
Symptoms of constipation have 1-2 bowel movements in a week, needing to strain to pass stools, difficulty in passing stools, hard stools and a feeling of incomplete evacuation.
There are several possible causes of constipation.

- Bowel stricture or colon becoming narrow
- Rectocele or a bulge or swelling in the rectum through the back part of the vagina
