    GlossaryHypothalamic Amenorrhea (FHA)

    disruption in brain function stops menstruation due to stress

    Hypothalamic Amenorrhea (HA) is a condition where menstruation stops for several months due to a disruption in the normal functioning of the hypothalamus, a part of the brain that regulates reproductive hormones. This disruption can be caused by factors such as excessive physical stress, significant weight loss, or emotional stress, leading to a decrease in the release of gonadotropin-releasing hormone (GnRH) and subsequently affecting the menstrual cycle.
