When women experience dysfunctional uterine bleeding, if this occurs during an anovulatory period, such as in adolescent or menopausal women, they generally do not experience abdominal pain. Some women have relatively regular menstrual cycles and only exhibit irregular bleeding between periods; these women still ovulate, and they may experience painful menstruation when their period comes.

Furthermore, if dysfunctional uterine bleeding persists, it can lead to a decrease in a woman's immunity. Some women may develop concurrent gynecological inflammation, such as inflammation of the endometrium or adnexa. Even if menstruation does not occur, these women may experience abdominal pain, presenting as unilateral lower abdominal pain or heaviness, and the pain may intensify during menstruation.

What to be aware of during a functional uterine bleeding curettage?

When women experience dysfunctional uterine bleeding, if oral medical therapy is ineffective, diagnostic curettage can be used to stop bleeding and to understand the causes of the bleeding. Before undergoing curettage surgery, women should not have sexual intercourse within five days to avoid infections in the reproductive tract. During the curettage process, it is crucial to thoroughly scrape the entire uterine wall, especially the areas around the corners of the uterus. If any abnormal scrapings, such as dirty, greyish-white substances that resemble endometrial cancer, are encountered during the scraping, the procedure should be terminated immediately to avoid causing uterine perforation. For one month after the surgery, sexual intercourse, sitz baths, and swimming should be avoided to prevent infections in the reproductive tract.

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.

What causes functional uterine bleeding?

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.

What are the symptoms of functional uterine bleeding?

Functional uterine bleeding is primarily characterized by severe disruptions in menstrual cycle, amount, and duration. The disruptions in menstrual cycles typically manifest as an early onset of menstruation. The amount of menstruation is typically characterized as excessive, and the duration tends to be prolonged. Some women experience heavy bleeding or incomplete clearing, where they may remain unclean for half a month or even one or two months. This condition is primarily seen in adolescent girls and women going through menopause. Adolescent girls with uterine bleeding may experience anemia, and it could lead to infertility later on. Menopausal uterine bleeding may be accompanied by severe anemia, requiring some to be hospitalized for blood transfusions. Moreover, it is essential to perform an ultrasound if the uterine endometrium is thick, to rule out endometrial pathology.
