Women who have irregular menstruation at the age of 45 may not need treatment or may be treated symptomatically to stop the bleeding, as follows: 1. No treatment is needed: usually all may not need any treatment therapy, and as long as such women do not have vaginal bleeding for a long time, they may not need any special treatment. This is because the ovarian function of women at the age of 45 has declined and may even fail completely, which is why it leads to abnormal menstrual performance. This is a normal performance for women at this age, so there is no need to take special medication to regulate menstruation. 2. Symptomatic hemostatic treatment: Only a small number of 45-year-old women may have anovulatory blood supply, which may require symptomatic hemostatic treatment, including caffeic acid tablets and scraping surgery to stop the bleeding.
