What is the reason for low menstrual flow and dark color?

Low menstrual flow and dark color may be related to endocrine disorders, endometrial damage, anemia, polycystic ovary syndrome, hypothyroidism and other factors. Low menstrual flow and dark color usually manifest as a significant decrease in menstrual bleeding volume and dark red or brown menstrual blood, which may be accompanied by dysmenorrhea or cycle disorders.

1. Endocrine disorders

Long-term mental stress, excessive dieting or obesity may lead to hypothalamic-pituitary-ovarian axis dysfunction, affecting estrogen secretion and causing insufficient endometrial hyperplasia. It may manifest as light menstrual flow and dark menstrual blood, which may be accompanied by insomnia or mood swings. It is recommended to adjust your work and rest schedule, and if necessary, use estradiol valerate tablets, progesterone capsules and other drugs to regulate hormone levels as directed by your doctor.

2. Endometrial damage

Multiple induced abortions, uterine cavity operations or severe uterine cavity infections may cause damage to the basal layer of the endometrium, causing the endometrium to become thinner and reduce shedding. It usually presents with continued decrease in menstrual flow and dull color, which may be combined with lower abdominal distention. Ultrasound examination is required to evaluate the intimal thickness, and the doctor may recommend using aspirin enteric-coated tablets and Compound Danshen Dropping Pills to improve intimal blood flow.

3. Anemia

In iron deficiency anemia or blood loss anemia, the body gives priority to ensuring blood supply to important organs, which may reduce uterine blood perfusion. Common menstrual flow is reduced, menstrual blood is dark brown, accompanied by fatigue and pale complexion. Iron-rich foods such as animal liver and spinach can be added in appropriate amounts. The doctor may prescribe ferrous succinate tablets, Shengxuening tablets and other blood-enhancing drugs.

4. Polycystic ovary syndrome

Insulin resistance and hyperandrogenemia inhibit follicular development, leading to ovulatory failure and endometrial growth restriction. Typical symptoms include oligomenorrhea, light and dark menstruation, which may be accompanied by hirsutism or acne. Six hormone tests are required to confirm the diagnosis, and the doctor may prescribe metformin sustained-release tablets and ethinyl estradiol cyproterone tablets for conditioning.

5. Hypothyroidism

Insufficient thyroid hormone will reduce the metabolic rate and affect the normal proliferation of the endometrium. Common symptoms include decreased menstrual flow and darker menstrual blood color, which may be accompanied by symptoms such as sensitivity to cold and edema. Thyroid function needs to be tested. After diagnosis, you can use levothyroxine sodium tablets, thyroid tablets and other alternative treatments as directed by your doctor.

It is recommended to record changes in menstrual cycles and menstrual flow, and avoid excessive dieting or strenuous exercise. You can drink rose tea and brown sugar ginger tea daily to warm the menstrual flow and dispel cold. You can also add pumpkin, red dates and other blood-enhancing foods appropriately. If the symptoms last for more than 3 months or are accompanied by severe discomfort, you should go to a gynecologist or endocrinologist in time to determine the cause through sex hormone tests, ultrasound, etc., and avoid taking hormone drugs by yourself.
