Long-term oral contraceptive use can lead to the occurrence of failure and therefore manifest itself in the form of unwanted pregnancies or recurrence of gynecological diseases in women. Oral contraceptives, on the one hand, can be used for contraception and, on the other hand, for the treatment of gynecological diseases, for example, when suffering from dysfunctional bleeding and endometriosis, long-term oral contraceptives can be used to relieve dysmenorrhea and reduce menstrual flow. In the case of polycystic ovary syndrome, it can help regularize the menstrual cycle and facilitate ovulation to facilitate pregnancy. Since birth control pills contain a large amount of hormones, women should take them according to their doctor’s instructions. Some medications should not be taken in combination to prevent the pill from failing and thus affecting a woman’s health.
