Expected Duration

In many teenagers with primary amenorrhea, puberty is late. But there is no permanent problem.

How long secondary amenorrhea lasts depends on the cause.

For example:

  • Pregnancy will stop a woman's menstrual periods until after childbirth.

  • A woman who stops taking birth control pills may not have a period for three months to a year.

  • Emotional or physical stress may cause amenorrhea for as long as the stress remains.

  • Rapid weight loss or gain, medications and chronic illness can cause missed periods.

  • Amenorrhea is permanent after menopause begins or after hysterectomy.
