There is no absolute relationship between post-menopause and the beginning or end of menopause. Generally, a few years before and after menopause fall within the scope of menopause, and since the physical quality of each woman is different, the time of entering menopause is also different. Menopause is characterized by the gradual shrinkage of the ovaries and the gradual decrease in the synthesis of estrogen and progesterone, which begins to manifest itself in the form of disorders of the menstrual cycle, abnormal uterine bleeding, and so on. Menopause occurs when menstruation stops for a year or more. The duration of menopause varies from one person to another, ranging from one or two years to more than ten years. In addition to disruptions in the menstrual cycle, menopause may also include hot flashes and night sweats, fatigue, irritability and insomnia. It is not possible to judge the beginning or the end of menopause by menopause, but it is important to consider the possibility of menopause if any of the above symptoms occur, and it is very important to pass through menopause peacefully, and if necessary, you may need to go to the hospital to have a checkup and take oral medication under the guidance of the doctor to regulate the situation.
