Constipation can develop as a result of a disease or even without any disease.
Constipation in children : It occurs in babies (or infants) who are completely or partially fed upon artificial diet, and in those whose mothers take improper diet. Mother’s milk has a laxative effect, therefore breast feeding must be encouraged.
Constipation during pregnancy : Hormonal changes, poor intake of fluids, vomiting results into a constant worry for many pregnant women.
Constipation in older adults : With the age, people tend to reduce their physical activity, develop other complaints, and the normal bowel movement is first to be effected.
Constipation in general

- Medicines prescribed for certain ailment like anticonvulsants (used for treatment of fits) can slow passage of food along the bowel, iron supplements (for treating anemia), antidepressants (to treat depression), or pain medications (especially narcotics).
- Ignoring the urge to have a bowel movement that allows the stool to stay for a longer period in intestine and there is a greater absorption of water from it, so as to make it harder and more difficult to pass. It is usually seen due to :
- Shyness, inhibition, concern over cleanliness in public places or while traveling. This is one of the underlying causes for ‘travel constipation’.
- Many kids refusing to use school bathrooms resulting in suppression of desire.
