Patient's question:
What is functional uterine bleeding?Doctor's answer:
Functional uterine bleeding, abbreviated as FUB, is a common gynecological disorder characterized by abnormal uterine bleeding. After examination, no systemic or genital organic lesions are found, but it is caused by dysfunction of the neuroendocrine system. It is manifested as irregular menstrual cycles, excessive menstrual flow, prolonged menstrual periods, or irregular bleeding. Based on ovulation, FUB is typically classified into two major types: anovulatory and ovulatory. The former is the most common, accounting for 80-90%, and primarily occurs during puberty and menopause. The latter is more common in women of reproductive age.
