Dysmenorrhea - Classification

Classification

Dysmenorrhea can be classified as either primary or secondary based on the absence or presence of an underlying cause. Secondary dysmenorrhea is dysmenorrhea which is associated with an existing condition. The most common cause of secondary dysmenorrhea is endometriosis. Other causes include leiomyoma, adenomyosis, ovarian cysts, and pelvic congestions. The presence of a copper IUD can also cause dysmenorrhea. In patients with adenomyosis, the levonorgestrel intrauterine system (Mirena) was observed to provide relief.
