How is anovulatory dysfunctional uterine bleeding diagnosed?

Xiaohong recently had irregular menstruation, heavy menstruation, long menstrual period, and continuous bleeding. She told her sister who was a doctor in another province about this. Based on the symptoms she described, her sister suspected that she had dysfunctional uterine bleeding and told her to seek treatment as soon as possible to avoid affecting fertility. Although Xiaohong was a little confused and worried about this, she still rushed to the hospital and was diagnosed with anovulatory dysfunctional uterine bleeding. So how is anovulatory dysfunctional uterine bleeding diagnosed?

The key to the diagnosis of anovulatory functional uterine bleeding is to exclude organic lesions of the whole body and internal and external genitalia, including bleeding from non-genital tracts (urinary tract, rectum and anus) and other parts of the reproductive tract (cervix, vagina), bleeding caused by organic diseases of the whole body or reproductive system, and iatrogenic uterine bleeding.

The basic diagnosis is based on the medical history, the course of the disease, the time of onset, the current bleeding situation, the history of amenorrhea before bleeding, and the previous treatment. The four types of uterine bleeding are distinguished: menorrhagia, frequent menstruation, irregular uterine bleeding, and irregular excessive uterine bleeding. Anovulatory functional uterine bleeding is usually irregular, sporadic, and unpredictable in terms of menstrual volume, duration, and interval of bleeding. It is common in physiological stages prone to anovulation: puberty and menopausal transition and anovulatory pathology such as PCOS. Through medical history, general examination, auxiliary diagnosis includes uterine imaging and histological examination when necessary. Diagnostic curettage, hysteroscopy, ultrasound or CT to exclude space-occupying lesions or pregnancy-related diseases, basal body temperature measurement, cervical mucus crystal examination, vaginal exfoliated cell smear examination, and hormone measurement and timely detection of progesterone can clearly give a diagnosis of anovulatory functional uterine bleeding.
