Which of the following is a potential cause of secondary amenorrhea?

The potential cause of secondary amenorrhea indicated by the selection is accurate as eating disorders like anorexia nervosa can significantly impact hormonal balance and overall reproductive health. In individuals with anorexia, the body often enters a state of energy deficit, which can disrupt the hypothalamic-pituitary-ovarian axis, leading to anovulation and interrupted menstrual cycles. This disruption can culminate in the absence of menstruation, which is defined as secondary amenorrhea when a person who previously had regular menstrual cycles stops menstruating for an extended period.

Other choices represent different biological or physiological states. Menopause is a natural transition in life where menstruation ceases, typically occurring around the age of 51, and is not considered secondary amenorrhea since it's a normal biological process rather than a result of an underlying condition. Late puberty indicates a delay in the onset of menstruation for individuals who are developing, and does not pertain to secondary amenorrhea, which primarily concerns individuals who have previously menstruated. Regular contraceptive use may also suppress menstruation, but it is not classified as a cause of secondary amenorrhea since it often leads to amenorrhea by design rather than due to an underlying health issue.
