What is the difference between polycystic ovary syndrome (PCOS) and hypothalamic amenorrhea?
PCOS is the condition of androgen excess when all other causes of androgen excess have been ruled out. It’s often associated with irregular periods or no periods.
Hypothalamic amenorrhea (HA) is irregular periods (or no periods) due to undereating or other stressors. It can also present with mild acne, facial hair, and polycystic ovaries.
