It is important for physicians who deal with adolescents to become familiar with the multiple facets of the symptom of constipation. Constipation is not a life-threatening problem; however, affected patients may suffer a great deal of angst and have their lives disrupted, especially when it is left untreated. A thorough history and physical examination will uncover the majority of predisposing problems that may contribute to constipation. Most adolescents are adequately treated by appropriate behavioral and lifestyle changes and pharmacologic interventions. Failure of treatment despite good compliance requires reconsideration of the differential diagnosis, further evaluation, and possible referral to the subspecialist.
