Normal menstruation is usually dark red in color. If the menstruation is black, it means that the menstrual flow is small and it is oxidized and turned black in the vagina, which may be caused by endocrine disorders, uterine adhesion or damage to the uterine lining.
1. Endocrine disorders: If you suffer from endocrine disorders, low levels of estrogen and progesterone cause the endometrium to be thin, and a small amount of exfoliation bleeding during menstruation will cause black menstruation.
2. Uterine adhesion: women with uterine adhesion will also have abnormal proliferation of endometrium and relatively small area of endometrium, resulting in less menstrual flow, and menstruation staying in the uterine cavity for a long time will cause black menstruation.
3. Damage to the uterine lining: If you have had multiple medication abortions or abortions, you will damage the uterine lining, resulting in a thinner lining, and black menstruation will occur when you have your period.
It is recommended that women who have black menstruation should go to the hospital in time for relevant examinations to clarify the cause of the disease, and then carry out symptomatic treatment under the guidance of the doctor.
