The normal amount of menstrual blood for women should be around 30-80 milliliters. If it remains below the lower limit for a long time, it indicates insufficient menstrual blood volume, especially for some women who not only have small menstrual blood volume but also turn black in color. This should be considered as an abnormal phenomenon during menstruation. So, what is the reason for women's infrequent and dark menstruation?
1. The color of female menstrual blood is black and the menstrual flow is small, which may be a normal physiological state, but pathological reasons cannot be ruled out. However, common physiological reasons are often related to women's age. For example, when some women enter menopause, their ovarian function gradually deteriorates with age, resulting in a corresponding decrease in the secretion of estrogen and progesterone. This can also lead to a decrease in physiological menstrual flow, and a small amount of menstrual blood may accumulate and be difficult to discharge from the uterus, leading to blackening of menstrual blood color.
2. There are many causes of blackening of menstrual blood color and reduced menstrual flow due to pathological reasons, such as a history of multiple induced abortions in women, which can lead to thin endometrium and poor postoperative recovery, resulting in endometritis and intrauterine adhesions. This can also significantly reduce menstrual flow each time, and inflammation can also cause blackening of menstrual blood color.
3. Women with less menstrual blood and black color also need to consider whether there are systemic diseases, such as thyroid dysfunction, endocrine disorders, etc. These causes are also important factors leading to less menstrual flow and black color of menstrual blood in women. Moreover, pathological reasons can lead to abnormal menstruation in women, which is often accompanied by various other discomfort symptoms. Therefore, women who experience multiple discomfort symptoms should seek medical attention promptly to clarify the cause and receive treatment.
