Functional uterine bleeding recovery time varies from person to person, mainly depending on the cause of the patient’s illness and treatment, the specific how long to recover in the clinic does not have an exact single point in time. Functional uterine bleeding includes ovulatory functional uterine bleeding and anovulatory functional uterine bleeding, and the causes of functional uterine bleeding are different for different ages and types of patients, and the treatment modalities are also different, so the recovery time also has individual variability. For example, anovulatory functional uterine bleeding often occurs in adolescent women, mainly due to the immature development of the hypothalamic-pituitary-gonadal axis, and the treatment should promote the development of the hypothalamic-pituitary-gonadal axis and ovarian ovulation while stopping bleeding. For perimenopausal women, it is necessary to counteract the effect of estrogen on the endometrium and promote amenorrhea in patients, which can be cured after curettage treatment in some patients. Prolonged blood loss in patients with functional uterine bleeding may lead to anemia, so treatment to stop bleeding should be accompanied by treatment to correct the anemia.
