Dysfunctional uterine bleeding can last for various durations; it varies from person to person. Some experience a shortened menstrual cycle, decreased period duration, prolonged menstrual duration, or excessive menstrual flow. Others may only have an extended cycle, and still others experience irregular, heavy, or prolonged bleeding. The duration of bleeding is not fixed and varies between individuals. When dysfunctional uterine bleeding occurs, endocrine tests are necessary, and corresponding treatment is required to address the issue. It is essential to seek treatment as early as possible.

What are the symptoms of functional uterine bleeding?

When women experience dysfunctional uterine bleeding, the clinical symptoms are varied. For example, some women still have a relatively regular menstrual cycle, occurring monthly, but exhibit bleeding between periods, such as the most common ovulatory bleeding. Other women experience vaginal bleeding before or after their period, such as when there is an abnormality in the function of the corpus luteum, leading to brown vaginal discharge clearly related to the menstrual cycle. Some women have irregular menstrual cycles, with no predictability of when menstruation will occur, characterized by intermittent spotting or irregular vaginal bleeding. If such conditions persist, they can lead to anemia from blood loss in women, manifesting as dizziness, fatigue, sleepiness, and loss of appetite.

Functional uterine bleeding is what?

Dysfunctional uterine bleeding is caused by abnormal ovulation, resulting in abnormal uterine bleeding. In adolescence, due to the immature development of the gonadal axis, most do not have normal ovulation. Although there is follicular development, the absence of ovulation means that the endometrium is not affected by progesterone. Therefore, when estrogen breakthrough bleeding occurs, it may manifest as irregular vaginal bleeding, excessive menstrual flow, or prolonged menstrual periods, which is the blood supply during adolescence. In menopause, women can also experience dysfunctional uterine bleeding due to ovarian failure, immature follicle development, abnormal ovulation, or the absence of ovulation, which can all cause irregular vaginal bleeding.

How to examine functional uterine bleeding?

Dysfunctional uterine bleeding primarily requires checking for any present anemia with routine blood tests and coagulation studies. Ultrasound is needed to examine the pelvis and uterine cavity, including the thickness of the endometrium. Treatment methods should be considered based on these results. Some cases can be managed with medication; others may require another diagnostic curettage to further clarify the condition of the endometrium; some may need contraceptives or similar treatments for 3-6 months, as this is fundamentally an endocrine issue involving hormonal imbalance, where hormonal treatment tends to be quite effective.

Is functional uterine bleeding related to a previous miscarriage?

Functional uterine bleeding in women, also known as dysfunctional uterine bleeding, occurs not due to organic lesions in the reproductive system but due to abnormalities in the function of the gonadal axis, leading to hormonal imbalances and dysfunctional uterine bleeding. This condition is generally unrelated to procedures like abortion or curettage. In some cases, it is triggered by issues such as delayed recovery of ovarian function following an abortion, excessive fatigue, or abnormalities in thyroid and adrenal gland functions, causing dysfunction of the gonadal axis. To address this issue, it is essential to first conduct tests, including a hormone panel and assessments of thyroid and adrenal gland functions, to identify the cause of the dysfunctional uterine bleeding and provide appropriate treatment.

Is functional uterine bleeding easy to treat?

Functional uterine bleeding is a common gynecological disease. The cause of functional uterine bleeding is relatively clear, so it is easier to treat clinically. Currently, oral hormonal drugs are widely used to treat functional uterine bleeding. Most patients have their endocrine disorders readjusted after taking oral hormonal drugs, returning to normal levels. After several courses of hormonal drug treatment, most women can recover and resume regular menstrual cycles.
