Other causes of constipation
Bowel movements are under voluntary control. This means that the normal urge people feel when they need to have a bowel movement can be suppressed. Although occasionally it is appropriate to suppress an urge to defecate (for example, when a bathroom is not available), doing this too frequently can lead to a disappearance of urges and result in constipation.
Fiber is important in maintaining a soft, bulky stool. Diets that are low in fiber can, therefore, cause constipation. The best natural sources of fiber are fruits, vegetables, and whole grains.
One suspected cause of severe constipation is the over-use of stimulant laxatives (senna [Senokot], castor oil, and many herbs). An association has been shown between the chronic use of stimulant laxatives and damage to the nerves and muscles of the colon, possibly resulting in constipation. It is not clear, however, whether the laxatives have caused the damage or whether the damage existed prior to the use of laxatives. Nevertheless, because of the possibility that stimulant laxatives can damage the colon, most experts recommend that stimulant laxatives be used as a last resort after non-stimulant treatments have failed.
Hormones can affect bowel movements. For example:
- Too little thyroid hormone (hypothyroidism) and too much parathyroid hormone (by raising the calcium levels in the blood) can cause constipation.
- At the time of a woman's menstrual periods, estrogen and progesterone levels are high and may cause constipation. However, this is rarely a prolonged problem.
- High levels of estrogen and progesterone during pregnancy also can cause constipation. Continue Reading
