What is the reason for less black menstrual blood?

Some female friends may find that their menstrual flow is relatively small and dark in color. Such symptoms can be considered as irregular menstruation. However, the symptom of irregular menstruation can be caused by many gynecological diseases, so patients must know what is wrong with their bodies. If you want to know more, you can check out the information below.

1. Hormonal imbalance: It is the most common cause of uterine bleeding, especially in adolescent girls and menopausal women. Hormonal imbalance causes anovulatory bleeding, which results in irregular menstruation during the first menstruation or when menopause is about to begin.

It will also cause unlimited growth of the endometrium, until the thickness of the endometrium grows to a level that the uterus cannot bear, causing breakthrough bleeding. Therefore, the amount of menstrual blood is often small and dark brown in the early stages, and will develop into heavy bleeding over time.

2. Difficulty in blood clotting: For example, people who lack platelets or have leukemia will have coagulation disorders, which will cause them to be unable to stop bleeding after menstruation, resulting in heavy menstrual flow.

3. Thyroid problems: If the thyroid function is too low or too high, it will cause ovarian dysfunction and irregular menstruation.

4. Poor liver function: Poor liver function can slow down female hormones, causing endometrial hyperplasia and abnormal bleeding.

5. Pregnancy: Due to problems with implantation or endometrial support, there will be abnormal bleeding in the early stages of pregnancy. At this time, you need to be careful about premature birth or miscarriage.

6. Malignant tumors: such as cervical cancer, endometrial cancer, ovarian cancer and some tumors that secrete female hormones, which cause the proliferation of the endometrium and lead to irregular menstruation, or direct invasion of the cervix by the tumor, causing bleeding.

7. Uterine tumor: This is the second most common cause of uterine bleeding. For example, uterine polyps, uterine fibroids, uterine adenomyomas, etc. can cause excessive menstrual bleeding. Some people with submucosal uterine fibroids or endometrial polyps often have heavy bleeding.

The situation and reasons for the small amount of black menstrual blood have been explained clearly above. I believe that after reading this, you will have a clearer understanding of irregular menstruation. In fact, female friends must have good living habits in life so that they can stay healthy. If you have irregular menstruation, you should also know how to regulate your body and restore your health.
