Overview
Amenorrhea is the absence of menstrual periods in women of reproductive age. There are two types of amenorrhea: primary and secondary. Amenorrhea can be caused by a variety of factors, including pregnancy, menopause, hormonal imbalances, and certain medical conditions such as thyroid disorders, polycystic ovary syndrome (PCOS), and eating disorders. Treatment for amenorrhea depends on the underlying cause and may include hormone therapy, surgery, or lifestyle changes.
