The differential diagnoses are broad and include gynecologic as well as gastrointestinal, urologic, musculoskeletal, neurologic, and psychiatric causes (Table 7B.1). Dysmenorrhea, in particular, is a common symptom among adolescents, affecting almost 70 percent of girls [1,2]. Primary dysmenorrhea, painful menstruation that cannot be attributed to pelvic pathology, is thought to be caused by an overproduction of uterine prostaglandins (PGs), which lead to increased myometrial contractility during menstruation. © Cambridge University Press, 2018." }
