Uterine bleeding caused by endocrine disorders is considered to be related to mental stress and gynecological endocrine diseases. 1. Mental stress: If a woman’s recent work pressure is relatively high or she often stays up late, it may lead to endocrine disorders, which may result in ovarian dysfunction, failing to produce estrogen and progesterone on a cyclical basis, which in turn leads to the endothelium not being able to be completely stripped off and continue to increase, and then lead to a significant increase in the amount of menstrual blood at the time of next menstrual period. 2. Gynecological endocrine diseases: for patients with polycystic ovary syndrome, hyperprolactinemia and other diseases, due to the body’s high androgen levels, low levels of estrogen and progesterone or elevated levels of prolactin, which in turn affects the follicle’s growth, development and discharge, the endometrium can not be peeled off in a regular manner, which may lead to heavy menstruation, prolonged menstruation, and other clinical manifestations. For women with endocrine disorders and heavy uterine bleeding, it is recommended that they go to the gynecology department of a regular hospital for consultation and active treatment under the guidance of a doctor after clarifying the cause of the disease.
