title: Evaluation and treatment of constipation and fecal impaction in adults.
abstract: Constipation is a common complaint that physicians encounter. Understanding the patient's definition of constipation and focusing the history and physical examination provide clues to the underlying cause. Initially, an empiric treatment trial is recommended. For patients with warning symptoms or those in whom treatment fails, a limited diagnostic work-up is suggested. Tests of physiologic function are reserved for patients whose condition is refractory to therapy. Fecal impaction can be considered extreme constipation. The pathophysiologic features of fecal impaction are discussed, and recommendations are provided for treatment and prevention.
