What is amenorrhea?
Amenorrhea is the absence of a menstrual period.
- Primary amenorrhea is when a young woman has not yet had a period by age 16.
- Secondary amenorrhea describes someone who used to have a regular period but then it stopped for at least three months (this can include pregnancy).
What are the signs of amenorrhea?The main sign of amenorrhea is missing a menstrual period.
Regular periods are a sign of overall good health. Missing a period may mean that you are pregnant or that something is going wrong (see What are the causes of amenorrhea?). It’s important to tell your health care provider if you miss a period so he or she can begin to find out what is happening in your body.
Amenorrhea itself is not a disease, but is usually a symptom of another condition. Depending on that condition, a woman might experience other symptoms, such as headache, vision changes, hair loss, or excess facial hair.

- Hypothalamic or pituitary diseases and physical problems, such as problems with reproductive organs, can prevent periods from starting.
- Moderate or excessive exercise, eating disorders (such as anorexia nervosa), extreme physical or psychological stress, or a combination of these can disrupt the normal menstrual cycle.
- Secondary amenorrhea
- This problem is much more common than primary amenorrhea.
