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.
Alternative Names
Irregularity of bowels; Lack of regular bowel movements
Considerations
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.
Fecal impaction (2 images)(Doctor-Reviewed information)
A fecal impaction is a large mass of dry, hard stool that can develop in the rectum due to chronic constipation. This mass may be so hard that it cannot come out of the body. Watery stool from higher in the bowel may move around the mass and leak out, causing soiling. Reviewer: Jenifer K.
