title: Menstrual disorders. Amenorrhea.
abstract: Adolescent patients with amenorrhea often present to primary care providers. A basic understanding of menstrual and pubertal physiology enables clinicians to initiate the clinical evaluation. A thorough history and physical examination focusing on pubertal development indicate the appropriate diagnostic algorithm. Usually, an accurate diagnosis can be obtained quickly. Management includes restoring ovulatory cycles if possible, replacing estrogen when necessary, reassurance, and re-evaluation.
