What are the reactions before menstruation?

Some female friends will feel vague abdominal pain before their menstruation, and often have the urge to have diarrhea. This is the most typical clinical manifestation. In addition, they will feel some blood on their underwear, but there is no obvious menstrual blood. This is mostly a sign that their menstruation is coming. During this period, you should take good care of your body to avoid catching a cold.

Symptoms

Before menstruation, there will usually be some small bloodstains on the underwear.

Before menarche, women's bodies undergo a series of changes. If you understand these changes, you can estimate the time of menarche.

Premonition

1. Measure weight and height: After a girl enters puberty (11-14 years old), measure her height and weight twice every six months. If a sudden increase in height and weight is found during a measurement, it indicates that the girl may have menstruation in the following six months.

2. Observe the condition of the breasts: If you find that the breasts begin to develop, swell and develop an areola, and there is a lump when touched, then menarche will occur within the next two years.

3. Check for leucorrhea: If a transparent or milky white, fishy or odorless, slightly viscous liquid like egg white flows out of a girl's vagina, it is a normal phenomenon; if the leucorrhea is found to be brown, it indicates that the first menstruation will come in 2-3 days.

If acne occurs (acne on the cheeks and forehead with small pustules), menstruation will come within 2 to 3 months.

Disease Signals

If a girl is over 18 and still has no menstruation, it is called primary amenorrhea; if a woman has had normal menstruation in the past but has stopped menstruating for more than three months, it is called secondary amenorrhea (excluding those caused by pregnancy, breastfeeding, and menopause), it is necessary to check whether there is lower reproductive tract closure, congenital apogonadism or uterine dysplasia, ovarian tumor, pituitary tumor or dysfunction, endocrine or wasting disease. In addition, changes in the time, amount, and accompanying symptoms of menstruation are also important clues for the discovery and diagnosis of many diseases.

Hematopoiesis

Menstruation causes the body to lose blood and produce blood regularly, which gives women's circulatory and hematopoietic systems a kind of "training" that men don't have. It makes women more able to withstand the shock of accidental blood loss than men, and can produce new blood more quickly to make up for the lost blood. Practice has shown that if men and women of the same weight and health status lose the same proportion of blood due to accidental blood loss, men will die, while women have the possibility of being successfully rescued and eventually recovering.

Reduce iron damage

There is a hereditary disease called hemochromatosis, which can easily cause iron metabolism disorders in patients, and excessive iron will accumulate in the body; excessive iron will slowly lead to lesions in the skin, heart, liver, joints, pancreatic islets, etc. One of the ways to treat excessive iron is to discharge a certain amount of blood regularly. The chance of organic damage caused by hemochromatosis in women is much lower than that in men, and it almost never occurs. The role of menstruation - periodic blood loss just consumes the excess iron.
