Dysfunctional uterine bleeding refers to the situation where a woman's uterus, ovaries, and brain do not have any actual organic lesions, such as the absence of uterine fibroids or ovarian cysts, yet there are functional changes that lead to bleeding. For example, the most common causes include excessive mental stress during schooling, emotional changes due to the death of a family member, or changes in living environment due to business trips, all of which can trigger uterine bleeding. In some cases, uterine bleeding may be a manifestation of a systemic disease; for instance, some women may experience it due to severe anemia or as a result of prolonged dieting and poor dietary habits leading to malnutrition and weight loss, especially if there is a sudden drop in weight. Additionally, some women may have metabolic diseases that can also cause uterine bleeding. Metabolic diseases include conditions such as elevated blood sugar, abnormal lipid levels, or anomalies in thyroid and adrenal gland functions.

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 heavy?

Functional uterine bleeding can be classified into different types. Clinically, some functional uterine bleeding can cause a large amount of bleeding in the vagina in a short period of time. In such cases, hemostatic treatment is crucial. If the patient does not receive timely hemostatic treatment, the continued vaginal bleeding and increasing blood loss can potentially lead to hemorrhagic shock. Therefore, in clinical practice, if there is a significant amount of functional uterine bleeding, diagnostic curettage is often used as a treatment approach. This method not only serves a diagnostic purpose but also achieves immediate hemostatic effects in a short duration.

Is functional uterine bleeding serious?

Dysfunctional uterine bleeding severity varies from person to person, depending on the specific bleeding situation and individual differences. Some people have mild symptoms and can improve by changing their lifestyle, such as losing weight, gaining weight if underweight, avoiding staying up late, and maintaining a regular life schedule. However, in some cases, dysfunctional uterine bleeding can lead to severe anemia, ineffective drug treatments, or endometrial changes, requiring procedures like curettage.

How to treat functional uterine bleeding?

Functional uterine bleeding should be treated according to the patient's age. If functional uterine bleeding occurs during adolescence, menstrual regulation treatment is needed. If it occurs during the reproductive age, it requires menstrual regulation and hemostasis, along with treatment to promote ovulation. If functional uterine bleeding occurs during menopause, it is mainly due to a lack of progesterone, and treatment with progesterone can be applied at this time. If there is endometrial thickening, dilation and curettage may be necessary, and the treatment plan should be determined based on the pathological results after the procedure.

Functional uterine bleeding is a common disease in women. The main cause of functional uterine bleeding is due to hormonal imbalances in the body, leading to irregular vaginal bleeding. This condition is divided into several different categories, each of which involves different types of endocrine disorders. Therefore, when a woman experiences functional uterine bleeding, it is advisable to visit a local hospital for gynecological color ultrasound and sex hormone tests, among others, to assess the state of the female reproductive and endocrine systems and to formulate the next steps in the treatment plan based on different results.
