What causes scanty menstrual flow and light blood?

Low menstrual flow and light blood may be caused by endocrine disorders, endometrial damage, anemia, polycystic ovary syndrome, hypothyroidism, etc. Symptoms usually include shortened menstrual periods, reduced menstrual blood volume, and lighter menstrual blood color.

1. Endocrine disorders

Long-term mental stress, disordered work and rest, or excessive dieting may lead to hypothalamic-pituitary-ovarian axis dysfunction and insufficient estrogen secretion. This kind of situation may be accompanied by menstrual cycle disorders, which can be improved through regular work and rest, and a balanced diet. If necessary, it is necessary to follow the doctor's advice and use drugs such as estradiol valerate tablets and progesterone capsules to regulate it.

2. Endometrial damage

Repeated abortions, uterine cavity operations, or severe infections may damage the basal layer of the endometrium, resulting in thinning of the endometrium and reduced shedding. Such patients may suffer from periodic abdominal pain and need to be diagnosed by ultrasound. They can use estradiol and dydrogesterone tablets as directed by the doctor to promote endometrial repair. Severe cases require hysteroscopic treatment.

3. Anemia

Iron deficiency anemia or megaloblastic anemia will cause the blood's oxygen-carrying capacity to decrease, causing menstrual blood to be diluted and appear pale pink. Patients often suffer from fatigue and dizziness, which can be diagnosed through blood routine. It is recommended to increase the intake of red meat and animal liver, and follow the doctor's advice to supplement ferric protein succinate oral solution, compound ferrous sulfate folic acid tablets and other drugs.

4. Polycystic ovary syndrome

Insulin resistance and androgen excess can inhibit follicular development, leading to oligoovulation and scanty menstrual flow. Patients often suffer from acne and hirsutism and require sex hormone examination and ultrasound diagnosis. They can use ethinyl estradiol and cyproterone tablets as directed by the doctor to adjust the cycle, and use metformin sustained-release tablets to improve metabolism.

5. Hypothyroidism

Insufficient thyroid hormone can reduce metabolic rate and affect endometrial hyperplasia. Patients often have symptoms such as cold sensitivity and weight gain, and their thyroid function needs to be tested. After diagnosis, long-term oral replacement therapy with levothyroxine sodium tablets is required, and TSH levels are regularly monitored.

It is recommended to record changes in menstrual cycle and menstrual flow, avoid excessive dieting or strenuous exercise, and ensure daily intake of sufficient high-quality protein and iron, such as lean meat, spinach, etc. If the symptoms last for more than 3 months or are accompanied by severe discomfort, you should promptly see a gynecologist or endocrinologist, complete six sex hormones, thyroid function, pelvic ultrasound and other examinations, and avoid taking hormone drugs by yourself.
