Dysmenorrhea: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Although primary dysmenorrhea has no known single cause, possible contributing factors include hormonal imbalances and psychogenic factors. The pain of dysmenorrhea probably results from increased prostaglandin secretion, which intensifies normal uterine contractions. (See Causes of pelvic pain, page 938.) Dysmenorrhea may also be secondary to such gynecologic disorders as endometriosis, cervical stenosis, uterine leiomyomas, uterine malposition, pelvic inflammatory disease, pelvic tumors, or adenomyosis.

Because dysmenorrhea almost always follows an ovulatory cycle, both the primary and secondary forms are rare during the anovulatory cycles of menses. After age 20, dysmenorrhea is generally secondary.

About prevalence and incidence statistics:

The term 'prevalence' of Menorrhagia usually refers to the estimated population of people who are managing Menorrhagia at any given time. The term 'incidence' of Menorrhagia refers to the annual diagnosis rate, or the number of new cases of Menorrhagia diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
