Amenorrhea is diagnosed when a woman does not get her period for at least 3-6 months. Primary amenorrhea is diagnosed when a woman never had a menstrual period or bleeding and when she does not get a menstrual period by the age of 14 or 16 years of age, while secondary amenorrhea is diagnosed in a woman who previously had a regular menstrual period but then it stopped. The main reasons for primary amenorrhea are blockages or narrowing of the cervix, a hymen that has no opening, a missing uterus or vagina and a vaginal septum (a wall that divides the vagina into 2 sections). The main reasons for secondary amenorrhea is when there is no ovulation such as in pregnancy, breastfeeding, and menopause, while other causes include polycystic ovarian syndrome, obesity, being underweight, thyroid disease, reduced ovarian function, taking certain medications and other causes.
