Unfortunately, menstruation for many women is comparable to flour. Despite the fact that this is an important physiological process. He is often accompanied by pain, irritability and weakness. But thanks to such a complex process of our body, we can conceive, endure and give birth to a child.
Process physiology
Not every girl knows why women have their periods. It is no secret that menstrual flow is a reflection of the internal state of health.
Menstruation begins in girls aged 11-13 years. The first discharge is irregular and not abundant. The average duration ranges from 3 to 5 days. In the first days, abundant discharge can be observed, which decreases by the third day.
It is worth noting that menstruation can take place both painlessly and be accompanied by unpleasant sensations in the lower abdomen.
Body features
The female uterus is presented in the form of an empty sac located in the lower abdomen. She has two fallopian tubes adjacent to the ovaries, which store a certain supply of eggs. In them, in turn, there are female chromosomes, which, when merged with the sperm, provoke the nucleation of a new organism.
As you know, girls from birth are given a certain set of eggs. That is why we can understand why women have their periods. The egg passes through the fallopian tube toward the uterus. This period is called the ovulatory cycle. At this point, a woman may become pregnant. If the sperm meets the egg, then they form a zygote, which moves to the uterus.
If the process of fertilization has not occurred, then the mucous layer of the uterus is rejected and comes out with menstruation.
Unfortunately, during menstruation, a girl may experience a change in psychological state. Most often, it is accompanied by tearfulness, irritability and short temper.
In such a period, a hormonal surge occurs in the female body . Signs of drowsiness, lethargy, nausea, skin rashes, and even diarrhea may appear. An unpleasant fact, but in some girls a few days before the start of the menstrual cycle, acne and acne can be observed.
Especially young girls often wonder why women have their periods. Some are hard to tolerate this period, as it is painful and is accompanied by violent emotional outbursts. But, each of us must understand that this process is conceived by nature and is necessary for the emergence of a new life.
What are the periods for?
The main task of the menstrual cycle is to prepare the woman’s body and body for the upcoming pregnancy.
It is believed that after the completion of menstruation in a woman’s body, a number of positive changes occur:
- In the brain, the active production of the hormone gonadoliberin begins, which subsequently sends a signal to stimulate the follicles. Then the follicle develops with the egg.
- Additionally, the production of the female hormone - estrogen. It is necessary for the regeneration of the uterine mucosa .
- Two weeks later, the luteal phase begins, and estrogen in the blood begins to decline.
- When the follicle bursts, the egg leaves the ovary in the uterine region and awaits the fertilization process. Then, the tissues under the influence of the hormone estrogen and progesterone turn into the corpus luteum. If conception has not occurred, then the level of hormones naturally decreases, and the mucous membrane of the uterine region begins to break down. The next menstruation comes, according to the length of your menstrual cycle.
Such a complex process takes place in the body of a woman every month to prepare for a future pregnancy and bearing a baby.
Menstruation during pregnancy
If fertilization has occurred, then why do women have their periods? The month following the onset of pregnancy, accompanied by spotting, cannot be called the menstrual cycle. In the period after fertilization, you must be as careful as possible about changes in your body. And in no case do not neglect the appeal to the gynecologist.
If a woman is pregnant, why do menstruation go? Unfortunately, most often this phenomenon is facilitated by pathological processes in the body of the expectant mother. And if you do not consult your doctor in time, then detachment of the fetal egg may occur, which as a result can lead to a miscarriage.
Most often, the discharge occurs due to an insufficient amount of the hormone progesterone. Also, the developmental pathology of the fetus, ectopic pregnancy and poor attachment to the uterine mucosa may be the reasons for the development of this condition.
Severe pain
Pain in the lower abdomen can begin to bother a woman several hours before the start of the menstrual cycle. The pain can last throughout the first day following the onset of menstruation. Today, it is difficult to answer: why some have discomfort during this period, while others have no discomfort.
Pain can be described as cramping, which can be followed by nausea, migraine, weakness and diarrhea. All these conditions are considered to be the norm, but if the nature of the discomfort and the amount of discharge has changed significantly, then it is better to consult a doctor.
Long menstruation
Why does a woman have a long period? During puberty and menopause, hormonal changes are possible, which have a significant impact on the duration of the menstrual cycle. Most often, the reason lies in estrogen. Despite the lack of discomfort in such periods, you need to contact a gynecologist to identify the cause.
Unfortunately, the question of why menstruation often goes on in women also requires the obligatory consultation of a specialist. This phenomenon can be caused by uterine bleeding and other troubles. Only a qualified specialist can determine the exact cause and make a diagnosis. And you, in turn, must visit the gynecologist in a timely manner and not let the solution to the problem by chance. After all, the birth of an unborn child depends on your health.
