At 57 years old, it is normal to have menstruation all the time without menopause.
The average age of menopause for women in China is 49.5 years old, and 80% of them are between 44 and 54 years old, so it is normal for a small number of people to have menopause at a later age. If you have menstruation until the age of 57 and have not gone through the menopausal stage, it is considered normal. If you have been menopausal before, i.e., you have stopped menstruating for more than half a year, it is abnormal to have vaginal bleeding at age 57.
Menstruation is affected by the level of estrogen in the body. Different estrogen levels may cause menopause to occur earlier or later. Menopause indicates ovarian failure.
If you are still having menstruation at the age of 57 and are having regular menstruation, there is no need to worry too much, you can go to the hospital for sex hormone and other related tests to clarify the specific situation.
