Dysmenorrhea

Overview

Definition

Dysmenorrhea is a painful menstrual period. It may be pain in the pelvis, abdomen, back, or legs, abdominal cramps, headache, and fatigue. This pain is severe enough to make day to day habits hard to get through.

There are 2 types of dysmenorrhea:

  • Primary—caused by uterine muscle contractions
  • Secondary—caused an underlying condition, such as endometriosis

Causes

Primary dysmenorrhea is caused by high levels of a hormone called prostaglandins.

Secondary dysmenorrhea is caused by a health issue such as:

  • Endometriosis
  • Ovarian cysts
  • Infection of the female reproductive organs—pelvic inflammatory disease
  • Noncancerous growths in the uterus—uterine fibroids
  • Intrauterine device (IUDs)
  • Scars from previous surgery
  • Tumors
  • Inflammatory bowel disease

Diagnosis

The doctor will ask about symptoms and past health. A pelvic exam will be done. Other tests may be done to look for possible causes. Tests may include:

  • Pelvic ultrasound
  • Hysteroscopy
  • Hysterosalpingogram
  • Pelvic laparoscopy
