DEFINITION--Severe, painful cramps during menstruation. Primary dysmenorrhea
means pain has recurred regularly since periods began. Secondary dysmenorrhea means pain
began years after periods started. Women with dysmenorrhea are generally fertile. Severity
of symptoms varies greatly from woman to woman, and from one time to the next in the same
woman. Dysmenorrhea usually is less severe after a woman has a baby.
BODY PARTS INVOLVED--Female reproductive system, especially the uterus.
SEX OR AGE MOST AFFECTED--Women of childbearing age.

- Cramping and sometimes sharp pains in the lower abdomen, lower back and thighs.
- Nausea and vomiting (sometimes).
- Diarrhea (occasionally).
- Sweating; lack of energy.
- Strong or prolonged contractions of the muscular wall of the uterus. These may be caused
by concentration of prostaglandins (hormones manufactured by the body). Research shows
that women with dysmenorrhea produce and excrete more prostaglandins than those who don't
have as much discomfort.
- Dilation of the cervix to allow passage of blood clots from the uterus to the vagina.
- Other causes include pelvic infections; endo-metriosis, especially if dysmenorrhea
begins after age 20; benign tumors of the uterus.
