What does it mean if menstrual blood is very dark?
Dark menstrual blood may be related to physiological causes, or it could result from pathological conditions such as endometritis or intrauterine adhesions. It is important to seek prompt medical evaluation in obstetrics and gynecology for accurate diagnosis and appropriate treatment based on the underlying cause.
I. Physiological Causes
When menstrual blood remains in the vagina for an extended period, it undergoes varying degrees of oxidation due to the acidic environment, leading to abnormal coloration. If the menstrual cycle is otherwise regular and no discomfort is present, special treatment is usually not required.
II. Pathological Causes
1. Endometritis
Inflammation can cause uneven shedding of the endometrium during menstruation, resulting in reduced menstrual flow and dark-colored blood. It is recommended to promptly perform a drug sensitivity test and follow medical advice to treat with medications such as cefixime capsules, metronidazole tablets, or amoxicillin capsules to stabilize the condition.
2. Intrauterine Adhesions
Cervical or intrauterine adhesions can impair normal endometrial growth, preventing progesterone and estrogen from properly affecting the endometrium and disrupting its regular cyclic shedding. This may lead to menstrual disorders, including dark menstrual blood. Patients should consult their doctor about using medications such as estradiol tablets/estradiol-dienogest tablets or sildenafil citrate tablets. In severe cases, hysteroscopic adhesiolysis may be considered.
Besides the above, conditions such as pelvic inflammatory disease may also contribute. During illness, maintain good personal hygiene and follow medical advice for regular hospital follow-up visits.
