stage after 12 months without a menstrual period
Postmenopausal refers to the stage in a woman's life that occurs after she has experienced 12 consecutive months without a menstrual period, marking the end of her reproductive years. This phase typically begins in women between the ages of 45 and 55 and is characterized by a decrease in the production of hormones such as estrogen and progesterone, which can lead to various physiological changes and symptoms, including hot flashes, osteoporosis, and changes in hair and skin.
