What is the cause of black menstrual blood

The appearance of black blood during menstruation may confuse many women and even worry them. In fact, the darkening of menstrual blood is usually because the blood stays in the uterus for a long time and becomes darker after oxidation. Generally speaking, this is not a big problem, but understanding the reasons behind it can help you better manage and pay attention to your health.

Dark blood during menstruation may be caused by slow menstrual blood flow. Menstrual blood stays in the uterus for too long and oxidizes when exposed to air, and the color naturally becomes darker. This is more common at the beginning or end of menstruation because the uterus does not contract strongly enough at this time, causing the blood to flow out more slowly.

Dark menstrual blood may also be related to the shedding of the endometrium. During menstruation, the endometrium is shed and discharged with the menstrual blood. If the endometrium is not completely shed, it may cause the menstrual blood to be dark in color. This condition is sometimes accompanied by mild abdominal pain or discomfort, but it is usually nothing to worry about.

However, if black menstrual blood is accompanied by other abnormal symptoms, such as severe abdominal pain, excessive or insufficient menstruation, irregular menstrual cycles, etc., you may need to pay attention. These symptoms may indicate endometriosis, uterine fibroids or other gynecological problems. In this case, it is recommended to consult a doctor as soon as possible to get professional advice.

In daily life, maintaining good living habits can help maintain menstrual health. Adequate sleep, a balanced diet and moderate exercise can help regulate hormone levels in the body and promote uterine health. It is also very important to have regular gynecological examinations to detect and deal with potential health problems in a timely manner.

In most cases, black blood during menstruation is a normal physiological phenomenon, but if it is accompanied by other abnormal symptoms, it still needs to be taken seriously. Pay attention to your own health and communicate with your doctor in a timely manner to better manage and maintain your health. I hope this information can provide you with some help and inspiration.
