What are the symptoms of functional uterine bleeding?

Dysfunctional uterine bleeding refers to functional bleeding in women. This bleeding can occur at many time periods and is somewhat similar to the characteristics of menstruation. However, the difference between functional uterine bleeding and menstruation can be distinguished through examination. When women find that their menstrual flow is heavy and they have frequent menstruation, they must pay attention to the abnormal physical symptoms to prevent the functional uterine bleeding from occurring instead of normal menstruation. Patients can go to the hospital for examination based on these abnormal symptoms. So what are the symptoms of functional uterine bleeding?

Dysfunctional uterine bleeding is caused by dysfunction of the neuroendocrine system. It often manifests as irregular menstrual cycles, excessive menstrual flow, prolonged menstruation or irregular bleeding. Depending on whether ovulation occurs or not, functional uterine bleeding is usually divided into two categories: anovulatory type and ovulatory type. The former is the most common, accounting for about 80-90%, mainly occurring during puberty and menopause, while the latter is more common in women of childbearing age. Common symptoms of functional uterine bleeding include the following:

1. Irregular uterine bleeding. Menstruation is early or late, with no regularity at all.

2. Frequent menstruation. The menstrual cycle is shortened, generally less than 21 days, and the amount of bleeding and number of bleeding days are normal.

3. Excessive menstrual flow. The menstrual cycle is normal, but the amount of bleeding each time is excessive, reaching hundreds of milliliters.

4. Menstruation is continuous and continuous. Some women have normal menstrual cycles, but they may have a small amount of bleeding for several days before their period, and the bleeding is often dark in color. The bleeding continues for several days after their period, and may continue for more than ten days before and after their period.

5. Ovulation bleeding. About 10 days after the menstruation ends, a small amount of bleeding begins to flow out of the vagina, sometimes stopping in a day or two. This is called ovulation bleeding. Functional uterine bleeding, due to frequent bleeding, large amount of bleeding, and long bleeding time, patients often suffer from anemia or symptoms such as fatigue, dizziness, tinnitus, pale complexion, etc. In severe cases, shock may occur and even life-threatening.

6. Dysfunctional uterine bleeding during puberty: occurs in girls after menarche, due to the immaturity of the HPOU axis, which prevents regular ovulation. Clinical manifestations include infrequent menstruation after menarche, irregular menorrhagia after a short period of amenorrhea, prolonged menstruation, and continuous spotting, leading to severe anemia.

7. Menopausal (perimenopausal) functional uterine bleeding: that is, functional uterine bleeding in women aged ≥ 40 years to around the time of menopause. The incidence of anovulatory functional uterine bleeding increases year by year during this period. The clinical manifestations are: frequent menstruation, irregular cycles, excessive menstrual flow, and prolonged menstruation. 10-15% of patients present with severe irregular menstruation, menorrhagia and severe anemia. Endometrial biopsy often shows varying degrees of endometrial hyperplasia, so curettage is necessary. Special attention should be paid to excluding non-functional uterine bleeding caused by gynecological tumors (uterine fibroids, endometrial cancer, ovarian cancer, cervical cancer).

What are the symptoms of functional uterine bleeding? The symptoms of functional uterine bleeding are very obvious, but careless people will not find the problem.

Therefore, everyone should pay attention to functional uterine bleeding to prevent the disease from causing great harm to the body.
