What does the term "amenorrhea" refer to?

Amenorrhea specifically refers to the absence of menstruation in a woman of reproductive age. This condition may indicate a range of health issues, including hormonal imbalances, pregnancy, significant stress, excessive weight loss, or other medical conditions affecting the reproductive system. Amenorrhea can be classified as primary (when menstruation has not begun by age 15) or secondary (when menstruation stops for at least three consecutive cycles after having been regular). Understanding that amenorrhea denotes the lack of the menstrual cycle helps in diagnosing and treating potential underlying health problems effectively.
