What tests should be done for functional uterine bleeding in adolescence?

The reason for adolescent functional uterine bleeding is that the ovarian function and ovulation mechanism are not yet perfect. Due to high study pressure, mental stress or intense exercise, nutritional imbalance, etc., ovarian dysfunction and abnormal sex hormone secretion occur, resulting in irregular vaginal bleeding. "Metrorrhagia" is divided into "mid-blooming" and "low-blooming". Mid-blooming means bleeding like a flood, with a lot of blood. Some girls suffer from severe anemia due to excessive blood loss. Therefore, if you have adolescent functional uterine bleeding, you should go to the hospital for examination in time. Common examinations include:

(1) Basal body temperature measurement: Generally, it is monophasic. Since the hypothalamic cycle center of most patients matures late, the hypothalamus-pituitary-ovarian can only establish negative feedback, but not positive feedback. Therefore, there is no LH peak in the middle of the menstrual cycle, which prevents the ovulation of mature follicles, so it is anovulatory functional uterine bleeding.

(2) Vaginal secretion smear examination: On the one hand, it can understand the estrogen level and cyclical changes. Since the patient's ovaries do not ovulate, there is no progesterone effect and no cyclical changes. On the other hand, it can also rule out rare malignant tumors.

(3) Estrogen and progesterone measurement: Generally there is no periodic fluctuation, especially progesterone, which always remains at the level of the proliferation phase.

(4) Diagnostic curettage: This examination can understand the endometrial reaction, exclude intrauterine lesions and achieve the purpose of hemostasis. It is rare for adolescents to have organic lesions or malignant diseases, and generally diagnostic curettage is not needed to assist in diagnosis; unless there is severe bleeding or drug treatment is ineffective, diagnostic curettage is needed. Curettage is the most rapid and effective method of hemostasis. According to statistics, a certain number of patients can stop bleeding immediately and recover naturally after curettage. If curettage is for diagnostic purposes, it should be performed 1-2 days before bleeding or within 12 hours after bleeding.

(5) Laboratory examination: routine blood tests, platelet count, and bleeding and coagulation times to determine the degree of anemia and the presence of blood diseases.

(6) Others should be routinely tested for thyroid, adrenal and liver function to exclude anovulatory functional uterine bleeding caused by these diseases.
