- Constipation refers to infrequent or hard stools, or difficulty passing stools.
- Normal patterns of bowel elimination vary widely from person to person and you may not have a bowel movement every day.
- Constipation is most often caused by a low-fiber diet, lack of physical activity, not drinking enough water, or delay in going to the bathroom when you have the urge to defecate.
- Children and adults should get enough fiber in their diet.
Alternative names
Irregularity of bowels; Lack of regular bowel movements
Definition
Constipation refers to infrequent or hard stools, or difficulty passing stools. Constipation may involve pain during the passage of a bowel movement, inability to pass a bowel movement after straining or pushing for more than 10 minutes, or no bowel movements after more than 3 days. Infants who are still exclusively breastfed may go 7 days without a stool.
Considerations
Constipation is a relative term. Normal patterns of bowel elimination vary widely from person to person and you may not have a bowel movement every day. While some healthy people have consistently soft or near-runny stools, others have consistently firm stools, but no difficulty passing them.
When the stool is hard, infrequent, and requires significant effort to pass, you have constipation. The passage of large, wide stools may tear the mucosal membrane of the anus, especially in children. This can cause bleeding and the possibility of an anal fissure.
Common Causes
Constipation is most often caused by a low-fiber diet, lack of physical activity, not drinking enough water, or delay in going to the bathroom when you have the urge to defecate. Stress and travel can also contribute to constipation or other changes in bowel habits.
Other times, diseases of the bowel (such as irritable bowel syndrome), pregnancy, certain medical conditions (like an underactive thyroid or cystic fibrosis), mental health problems, neurological diseases, or medications may be the reason for your constipation. More serious causes, like colon cancer, are much less common.
Constipation in children often occurs if they hold back bowel movements when they aren't ready for toilet training or are afraid of it.
Home Care
Children and adults should get enough fiber in their diet. Vegetables, fresh fruits, dried fruits, and whole wheat, bran, or oatmeal cereals are excellent sources of fiber. To reap the benefits of fiber, drink plenty of fluids to help pass the stool.
For constipated infants:
- Over 2 months old - try 2-4 ounces of fruit juice (grape, pear, apple, cherry, or prune) twice a day.
- Over 4 months old - if the baby has begun solid foods, try baby foods with high-fiber content (peas, beans, apricots, prunes, peaches, pears, plums, spinach) twice a day.
Regular exercise is also important in establishing regular bowel movements. If you are confined to a wheelchair or bed, change position frequently and perform abdominal contraction exercises and leg raises. A physical therapist can recommend exercises appropriate for your physical abilities.
