The majority of bleeding caused by endocrine disorders is caused by the shedding of the endometrium. If you have intercourse in this situation, because the vagina is connected to the outside world and to the cervix and the uterine cavity, intercourse may cause pathogenic bacteria to be brought into the vagina and then into the uterine cavity, and at this time the endometrium is shed and traumatized, which may cause pathogenic bacteria to infect the traumatized surface and cause endometrial inflammation and even pelvic inflammation, so intercourse is not recommended at this time. It is recommended to actively treat the endocrine disorder, to understand what causes it through examination and to give treatment according to the specific situation so as to improve the symptoms of vaginal bleeding.
