When one cannot pass stools or finds it difficult to have a clean bowel movement at least three times a week, it is diagnosed as constipation. The bowel movement could be painful, and the stool could be small, hard and dry. Moreover, one could feel bloated before and after passing stools. While doctors may prescribe some treatment options, one can ease constipation by following a fiber-rich food regime. Causes of constipation Constipation is a common problem, affecting both children and adults but the cause of the condition may vary among children and adults. Young children may withhold their bowels or may not have adequate toilet training. Some may feel shy or repulsed at the idea of passing stools. Changes in food regime, inadequate hydration, and lack of fiber-rich foods can cause constipation in children.  In adults, nutritional deficiencies, lack of adequate fiber, dehydration, and improper habits are the major reasons for constipation. In some cases, preexisting conditions like irritable bowel syndrome (IBS), diabetes, hypercalcemia, hyperthyroidism, and muscular dystrophy can also cause constipation.  If one has had constipation for more than two weeks, experiences severe abdominal pain, or notices blood in stools, it is important to visit a doctor immediately. Doctors will prescribe treatment options that soften stools and conduct additional tests to identify the root cause of constipation.
