The 76-year-old woman is now 46 years old, and the absence of menstruation in women after the age of 45 can be considered a normal physiological phenomenon, or it may be related to diseases. Women between the ages of 45 and 55 have reached perimenopause, so it is normal for menstruation to stop during this period. Diseases may also cause menstrual disorders, such as polycystic ovary syndrome, etc. If middle-aged women do not have menstrual problems but also suffer from hairiness, acne, obesity, etc., they need to consider polycystic ovary syndrome, and can go to the hospital for a detailed checkup to rule out the possibility of delayed menstruation caused by diseases. It is recommended that when women have menstrual problems, they should not blindly use medication on their own, but should go to the hospital in time for examination to determine the cause, and then target treatment.
