Costiveness is the term often used to describe constipation, which refers to infrequent and difficult bowel movements. There are a few synonyms for costiveness, including constipation, irregularity, obstruction, dyschezia, and the colloquial term, being "backed up". These synonyms all refer to the same condition, in which stool becomes hard, dry and difficult to pass, causing discomfort and pain. To alleviate costiveness, a healthy diet, regular exercise, and plenty of water can help keep bowel movements regular. In some cases, laxatives or other medications may be needed to provide relief and promote healthy bowel function.
