The age of menopause is between 45 and 55 years old, with the average age being around 50 years old. However, the age of menopause varies from woman to woman due to different life factors, work stress, genetic factors, etc., which may affect the hormone levels, and thus the age of menopause also varies. Menopause is also known as menopausal transition, which refers to the period from the beginning of the menopausal trend until the last menstrual period, and is generally more common in women over the age of 40, with some women having a shorter history, which may take 1-2 years, and some patients having a longer history. During the menopausal transition period, ovarian function gradually declines, the number of follicles decreases significantly, and follicular hypoplasia occurs easily, leading to irregular menstruation, often characterized by anovulatory menstruation. It is recommended that women who experience discomfort during menopause should consult a specialist.
