World Menopause Day is observed worldwide every October 18. It was initiated by the International Menopause Society, a UK-based organization established in 1978 during the second Menopause Convention in Jerusalem, Israel. The day aims to promote knowledge about menopause, its symptoms, and the impact of estrogen loss on women's health. It focuses on various aspects of women’s health related to menopause, such as cardiovascular health and memory problems. Menopause, which typically occurs between ages 49 and 52, marks the end of menstruation and fertility due to decreased hormone production by the ovaries. The observance encourages the dissemination of information to help women cope with this significant life transition.
