What causes dark-colored menstrual blood with a light flow?
In general, black-colored menstrual blood with a low volume may be related to factors such as age, stress and lifestyle, endometritis, polycystic ovary syndrome (PCOS), and endometriosis. If discomfort occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under the guidance of a healthcare provider. Specific analyses are as follows:
1. Age
During early puberty or around menopause, significant fluctuations in female hormone levels may lead to darker menstrual color and reduced flow. It is recommended to engage in moderate exercise and ensure adequate nutritional intake to help alleviate symptoms.
2. Stress and Lifestyle
Chronic psychological stress and unhealthy lifestyle habits may cause darker menstrual blood and decreased volume. It is advisable to adjust lifestyle practices by ensuring sufficient rest and sleep, maintaining a balanced diet, and engaging in regular physical activity.
3. Endometritis
The inflammatory response caused by endometritis may lead to uterine endometrial congestion, thereby affecting normal menstrual discharge. The inflammation may also interfere with the shedding and repair process of the endometrium, resulting in reduced menstrual flow and dark-colored blood. Symptoms may include lower abdominal pain and fever. Patients can use medications such as metronidazole tablets, clindamycin hydrochloride capsules, and amoxicillin granules under medical supervision.
4. Polycystic Ovary Syndrome (PCOS)
PCOS may cause elevated levels of androgens and relatively reduced estrogen levels in women, which can affect normal endometrial growth and shedding, leading to reduced menstrual flow and dark-colored blood. Symptoms may include infertility, hirsutism, and acne. Treatment may include medications such as ethinylestradiol/cyproterone acetate tablets, medroxyprogesterone acetate tablets, or dydrogesterone tablets, used according to medical advice.
5. Endometriosis
Endometriosis refers to the presence of endometrial tissue outside the uterus. During the menstrual cycle, this ectopic endometrial tissue bleeds, but due to its abnormal location, blood drainage is impaired. This may cause menstrual blood to remain in the body longer, resulting in darker blood color and reduced volume. Symptoms may include dysmenorrhea, painful intercourse, and infertility. Patients are advised to take medications such as danazol capsules, medroxyprogesterone acetate tablets, or norethisterone tablets under a doctor’s guidance.
Patients are encouraged to maintain healthy lifestyle habits, follow a regular daily routine, and eat a balanced diet, which may help alleviate symptoms.
