Why does menstruation appear dark, light, and long?

Normal menstruation lasts for 5-7 days, with a cycle of 28-31 days. However, due to many reasons, many women's menstruation becomes irregular. Nowadays, many women do not have their periods, or their periods last only three days, and their menstrual blood may be dark. Why does menstruation appear dark, light, and long? There are several reasons, as follows:

Women also experience very painful menstruation, especially dysmenorrhea on the first day. The number of days for menstruation varies depending on physical condition. For some people, menstruation can end in four days, while for others it takes a week. When menstruation comes, some blood is bright red, and some is black. What is the reason for a small amount of black blood and a long time of menstruation?

Dark menstrual color and small amount of menstruation may be related to endocrine disorders, gynecological inflammation, etc. The causes of scanty menstruation include

1. Excessive menstruation is caused by hypopituitarism, insufficient estrogen secretion from the ovaries, and low estrogen levels in the body, which leads to insufficient endometrial proliferation. 2. Endometrial hypoplasia and endometrial tuberculosis.

3. There are also individual differences, that is, after menarche, the menstrual flow is always very small, but ovulation and reproductive functions are normal. 4. Progressive menstrual reduction is often a precursor to amenorrhea. Therefore, it is recommended to go to the hospital for examination in order to find out the cause and treat it.

1. Poor uterine contraction ability:

The shed endometrium and menstrual blood flow out of the body under the pressure of the uterus. When the uterus contracts, it compresses the menstrual blood out of the body. If the uterus's contraction ability is not good, the menstrual blood will not flow out of the body easily. If it stays in the body for a long time, it will easily turn black.

2. Retroverted uterus:

For women with a retroverted uterus, the position of the uterus causes the cervix to be higher than the uterus, so menstrual blood cannot flow out of the body all the way. Therefore, menstrual blood accumulates in the uterus for a long time and turns dark red or black.

3. Cold body:

Generally, people with cold body have slow blood circulation, and because of the cold body, the menstrual blood is exposed to the cold and coagulates, so there will be black or dark black blood clots in the menstrual blood.

Why does menstruation occur? After a woman reaches maturity, a mature egg will flow out of the uterus every month because it fails to combine with sperm. At this time, it will be accompanied by menstrual blood, so the color of menstrual blood is dark red. If blood clots are formed, then it is normal for it to be black. If you have this problem and are very worried, then ask your doctor to prescribe some Chinese medicine for you.
