What are the abnormal menstrual manifestations in patients with functional uterine bleeding?

Lingling, who is already a sophomore, has been having irregular menstruation for some time. She often has irregular bleeding. Her menstruation is frequent, which makes her feel dizzy and listless at work. However, she never tells her parents about it because she is shy. However, her careful mother noticed that something was wrong with Lingling's face. After being pressed, Lingling finally answered the truth. Her mother took Lingling to the hospital immediately. After examination, she was diagnosed with dysfunctional uterine bleeding. This result made Lingling feel a little puzzled. She thought that her classmates also had irregular menstruation and heavy menstrual flow. Could it be dysfunctional uterine bleeding?

Irregular menstruation and heavy menstrual flow do not necessarily mean that you have dysfunctional uterine bleeding. Generally, there are four types of abnormal menstrual symptoms in patients with dysfunctional uterine bleeding:

①Menorrhagia: The cycle is regular, but the menstrual flow is excessive or the menstrual period is prolonged.

② Frequent menstruation: The cycle is regular but shorter than 21 days.

③Irregular uterine bleeding: uterine bleeding that occurs at any time other than normal menstruation.

④ Frequent menstruation: irregular cycles and excessive bleeding.

The menstrual abnormalities of anovulatory functional uterine bleeding are mainly manifested as abnormal menstrual cycle, menstrual period, and menstrual volume. The irregular cycle is sometimes preceded by a significant shortening of the cycle, followed by irregular vaginal bleeding; sometimes there is amenorrhea for several weeks or months, followed by irregular vaginal bleeding; sometimes there is irregular vaginal bleeding from the beginning; it can also be manifested as cyclical bleeding similar to normal menstruation, with a menstrual period lasting more than 10 days or even several months. Or the amount of bleeding is large and urgent, or the bleeding is more or less, and it is not clean. The menstrual abnormalities of ovulatory functional uterine bleeding are mainly shortened menstrual cycles, that is, frequent menstruation, which can be manifested as a small amount of bleeding a few days before the menstrual period, followed by the onset of formal menstruation. In addition, patients with functional uterine bleeding will also show symptoms such as physical weakness, dizziness, fatigue, fatigue, palpitations, shortness of breath, edema, decreased appetite, and insomnia.
