Patient's question:
Is menorrhagia the same as uterine functional bleeding? What are the symptoms?Doctor's answer:
Hello, dysfunctional uterine bleeding is abbreviated as DUB and is a common gynecological disease. It is caused by abnormal uterine bleeding due to disorders in the neuroendocrine mechanisms that regulate reproduction, while there are no organic lesions in the whole body or in the internal and external reproductive organs. DUB is divided into two types: anovulatory dysfunctional uterine bleeding and ovulatory dysfunctional uterine bleeding. The former occurs when ovulation function is impaired and is more common in adolescents and postmenopausal women; the latter is due to luteal dysfunction and is more common in women of reproductive age. The main symptoms of DUB include irregular menstrual cycles, increased menstrual flow, prolonged bleeding duration, and intermittent spotting.
