    Low menstrual flow and blood clots may be caused by endocrine disorders, endometrial damage, anemia, adenomyosis, polycystic ovary syndrome, etc., which can be improved through hormone therapy, nutritional supplements, drug conditioning, etc.

    1. Endocrine disorders

    Staying up late or being under mental stress for a long time may lead to hypothalamic-pituitary-ovarian axis dysfunction, which is manifested by shortened menstrual cycles, reduced menstrual flow and black blood clots. It is recommended to adjust your work and rest and use progesterone capsules, estradiol valerate tablets and other medications as directed by your doctor.

    2. Endometrial damage

    Multiple artificial abortions or uterine cavity operations may damage the basal layer of the endometrium, resulting in thinning of the endometrium, poor menstrual blood discharge and formation of blood clots. When accompanied by lower abdominal pain, you can use Chinese patent medicines such as Guizhi Fuling Capsules and Shaofu Zhuyu Granules as directed by your doctor.

    3. Iron deficiency anemia

    When hemoglobin is lower than 110g/L, insufficient oxygen supply to the endometrium will affect the shedding process, causing menstrual blood to be dark in color, small in volume, and mixed with membrane-like objects. It is necessary to supplement iron supplements such as ferrous succinate tablets and ferric protein succinate oral solution, as well as the intake of iron-rich foods such as animal liver.

    4. Adenomyosis

    Invasion of the endometrium into the myometrium will cause the uterus to enlarge and harden. During menstruation, uterine contractions are weak and cause menstrual blood to be retained. A large number of dark red blood clots can be seen during discharge. After diagnosis, drugs such as dienogest tablets and leuprolide acetate microspheres for injection can be used to control the lesions.

    5. Polycystic ovary syndrome

    Hyperandrogenism will inhibit follicle development and lead to insufficient endometrial hyperplasia, which is manifested by oligomenorrhea, light menstrual flow and sticky blood clots. Long-term use of drugs such as ethinyl estradiol cyproterone tablets and letrozole tablets is required to regulate metabolic abnormalities.

    You should keep your abdomen warm every day, avoid strenuous exercise during menstruation, and drink 1500-2000 ml of warm water every day to promote metabolism. In the diet, increase the intake of iron-containing foods such as lean meat, spinach, and black fungus, and limit the stimulation of raw, cold, and spicy foods. If the symptoms last for more than 3 months or are accompanied by severe dysmenorrhea, gynecological ultrasound and six sex hormone tests must be performed promptly. Establishing a regular menstrual diary to record cycle changes can help doctors determine the cause of the disease.
