Why is there less blood during menstruation?

What is the reason for less menstrual blood volume? I believe many women don’t care about this. After all, society and economy are developing rapidly, and many things pass in the blink of an eye. If girls don't work hard, they will easily be left behind by society. How can they have the energy to pay attention to these small details? But no matter how tired you are at work, you still have to take good care of yourself. If possible, why not read the article and pay attention to your body from time to time.

What is the cause of less menstrual blood?

Small menstrual flow means that a woman has too little blood during her period, or her menarche is too short. Menstrual volume refers to the total amount of blood loss during a menstrual period. Normal menstrual volume is 20-8b250l. If it is lower than this standard, it is considered too little menstrual volume. Generally speaking, if a pack of sanitary napkins (10 pieces/pack) is not used in each period, and there is very little blood on one piece, but only soaking the surface, it means that the menstrual flow is small.

What is the reason for light menstrual flow? Some women have very light menstrual flow from the beginning of their first menstruation. This may be caused by uterine hypoplasia. If the menstrual flow, which has always been normal, suddenly decreases, it may be caused by abnormal hormone secretion or anovulatory menstruation.

The main reasons for the small amount of menstrual flow include the following three aspects :

1. Uterine hypoplasia. Menstruation is the shedding and bleeding of the uterine wall that occurs with the change of the uterine and ovarian cycle. If the uterus is underdeveloped, such as the uterus is not large or is deformed, only a small amount of uterine wall will fall off in each menstrual cycle, resulting in a small amount of menstrual flow. In addition, endometrial tuberculosis causing endometrial degeneration or curettage causing damage to the uterine wall can also lead to scanty menstruation or even amenorrhea.

2. Abnormal growth hormone metabolism. Estrogen can stimulate the proliferation of women's uterine wall. If the body's hormone secretion is abnormal, the proliferation of the uterine wall will not reach the required thickness, resulting in less menstrual flow. Excessive dieting, excessive work and rest time, bad mood, urinary system diseases, etc. will affect the female endocrine environment, causing abnormal hormone secretion and small menstrual flow.

3. Anovulatory menstruation. Women who do not ovulate will still have their periods, which is medically called "anovulatory menstruation." This is different from normal menstruation and falls into the category of "multifunctional abnormal uterine bleeding". The characteristics of this type of menstruation are irregular time and very little blood.

Will I continue to have my period if I'm pregnant?

Generally speaking, the first sign of a woman's pregnancy is amenorrhea. Under normal circumstances, women will not have their periods again after they become pregnant. A married or conjugal woman with a regular menstrual cycle should think of the possibility of pregnancy if her menstruation is delayed, but this is not certain. There are very few women who still experience vaginal bleeding at the time of their next menarche after becoming pregnant. This type of menstruation after pregnancy is called "pregnancy menstruation."

Its characteristics are less bleeding, lighter color, shorter duration, and different from all previous menstrual periods. In fact, this is not a real menstrual period. This condition usually occurs within 3 months of pregnancy and usually only occurs once. Some pregnant women also experience it 2 to 3 times.

1. Because the embryo implantation is not stable, the embryo has not been produced, and it is close to or on the day of menstruation, a perfect egg cell will be discharged, and then fall out of the body along the uterine wall, which leads to a small number of pregnant women thinking that they are having their period.

2. Due to individual differences and other reasons, some women's uterus and ovaries secrete relatively low levels of estrogen, especially progesterone, after pregnancy, causing a small part of the uterine wall to continue to fall off. Therefore, these women will still have their periods after pregnancy, but the amount of menstruation will be much less than in the normal stage. Until three months after pregnancy, the embryo is produced, and the female hormones and estrogen in the woman's body remain at a relatively high level. At this time, the uterine wall no longer falls off, and the menstrual period no longer comes.
