Abnormal uterine bleeding (AUB): Abnormal uterine bleeding is bleeding from the vagina that occurs frequently or irregularly or lasts longer or is heavier than normal menstrual periods. The most common type of abnormal bleeding results from changes in the hormonal control of menstruation that cause problems with release of the egg (ovulation).This type is called abnormal uterine bleeding due to ovulatory dysfunction (AUB-O).
Amenorrhea: Amenorrhea is the absence of a menstrual period in a woman of reproductive age. Physiological states of amenorrhea are seen, most commonly, during pregnancy and lactation (breastfeeding), the latter also forming the basis of a form of contraception known as the lactational amenorrhea method.
Hormone replacement therapy: Hormone replacement therapy (HRT) is a treatment to relieve symptoms of the menopause. It replaces hormones that are at a lower level as you approach the menopause.
Endometrial hyperplasia: Endometrial hyperplasia is a condition of the female reproductive system. The lining of the uterus (endometrium) becomes unusually thick because of having too many cells (hyperplasia). It’s not cancer, but in certain women, it raises the risk of developing endometrial cancer, a type of uterine cancer.
